FRUITFUL FUTURES

April 15, 2021/10 Comments/in Fruit/by Lee Reich

Making the Best of It

Eek! Mice (or rabbits)! Not the animals but the damage they have wrought. The bark on virtually all my pear grafts of last year has been nibbled off enough to kill the grafts.

Once I calmed down, I realized that all was not lost. All the chewing was above ground level, leaving a small amount of intact bark still in place. The plants aren’t dead, just their portions above the chewing. The near-ground portions could be grafted again.

(Most fruit trees neither come true from seed nor root readily from cuttings, so are propagated by grafting a scion — a short length of one-year-old stem — of the desired variety onto a rootstock. The rootstock is the same kind of plant as the scion variety and could be a seedling or a variety developed for special rootstock purposes. My nibbled trees are pear trees, Highland, Blake’s Pride, and other varieties, each grafted on a rootstock named Old Home X Farmingdale 87, which dwarfs the trees’ final height to about half that of a full-size pear tree, as well as induces it to yield its first fruits sooner.)

Damaged rootstock

Crouched way down at ground level would be a tough position for grafting, not to mention trying to keep dirt and debris off the cut surfaces. So I dug up each plant for “bench grafting,” so named because it’s done at a bench or, more generally, upright and in the comfort and better light of indoors.

My graft of choice for these wounded plants is the whip graft. It’s a simple graft, especially for apple and pear; I typically expect 95+ percent “takes.” With a well-honed, preferably straight-edged (and preferably single-bevelled) knife, I make a smooth, sloping cut about 3/4-inch long on the rootstock. Typically, I would make the cut longer but there’s not that much viable stem above-ground.

Making the cuts on rootstock and scion

Next, I take a scion of similar thickness to the rootstock, although this is not all-important, and make a similarly smooth, sloping 3/4-inch long cut.

If the cuts are secured face to face and then sealed against moisture loss, cells at the cuts start to multiply, eventually knitting the two pieces together and joining their vascular tissue. If the two plant pieces are not matching in thickness, success can still be achieved if just one side of the two of them is aligned. A piece of rubber, either a cut open rubber band or a bona fide grafting rubber, keeps cut edges of scion and rootstock intimate, and then the wound is sealed with Tree-Kote or similar tree wound material, or Parafilm tape.

Sealing the graft with Parafilm

Keeping the roots moist and the plants indoors for a couple of weeks speeds growth of new cells. After that, the plants will go outdoors, either potted up or planted in the ground.

The Downside to Low Grafting

Grafting so low on the plant does have its downsides. For one thing, a certain amount of rootstock stem above ground level is needed for the dwarfing effect. For full effect, grafts are usually made 6 to 12 inches above ground level.

Also, if a graft is very low on a plant so that over the years it gets covered with soil, the scion is could eventually root. At which point the dwarfing and other benefits of the rootstock are lost.

On the plus side, if any of my grafts fail, the still viable rootstock will undoubtedly send up a new shoot, which can be grafted next spring — and done well above ground level.

So How Do You Get a Rootstock?

The way to get a rootstock is to buy one (ha, ha). But how does as nursery make, for instance, an Old Home X Farmingdale 87 pear rootstock if pears (and most other tree fruits) are so hard to root and don’t come true from seed.

Rootstocks are bred or selected to impart special characteristics to the tree for which they provide roots and a short length of stem — very short stems in the case of this week’s pear grafts. Another characteristic that might be sought in a rootstock is ease of propagation, perhaps even by cuttings.

Whereas a pear variety such as Blake’s Pride is propagated from mature, fruiting wood, a rootstock might be propagated from juvenile wood, that is, wood that that has never grow to maturity. All plants are easier to multiply from juvenile wood. Near the base of a plant that has been raised from seed, the wood retains its juvenility, so a seed-propagated rootstock variety that was repeatedly cut back would provide stems that were juvenile and could be rooted as cuttings.

And there are other ways to coax new plants from an existing plant, such as tissue culture and stool layering. Maybe something about these methods at another time.

Fruitful Near Futures

Even grafted higher atop a rootstock that imparts precocity, my pear grafts aren’t apt to yield their first crop for a few years. My Nanking cherry bushes (Prunus tomentosa), on the other hand, are slated to have bright red cherries arching their stems to the ground in a couple of months or so.

A profusion of Nanking cherries!

The cherries are small, but are very juicy with a refreshing flavor that combines that of sweet and tart cherries. Another plus for these plants is that they are more or less free of pest problems, requiring no care on my part beyond picking the fruit. Read more about them in my book Landscaping with Fruit.

No need to ignore the bushes until payday because payday is also right now, visually. Along the length of my driveway, the hedge of Nanking cherries has turned into a cloud of dense, slightly pink, white flowers. This time of year it’s not uncommon for a biker or walker to stop and ask the name of the plants. “Nanking cherry!”

OUTDOOR MAPLES AND INDOOR KUMQUATS

February 24, 2021/23 Comments/in Fruit, Houseplants/by Lee Reich

Sap Season

Get your taps in. It’s syrup weather. Maple syrup. At least here in New York’s Hudson Valley, the sunny days in the 40s with nights in the 20s that are predicted should get the sap flowing.

I say “should” because I haven’t yet checked sap buckets that I hung out on the trees a few weeks ago when winter temperatures suddenly turned warm; it was sap weather back then. That day was hopeful: I drilled holes an inch and a half deep, lightly hammered in the spiles, hung buckets, and attached covers over the buckets. Frigid days and nights that descended soon after that kept sap flow in abeyance.

My “sugar bush” amounts to only three sugar maple trees. I used to have four, but a large tree that was a truly magnificent representative of its species began an irreversible path to its death. “Maple decline” is a disease complex brought on by some combination of drought, soil compaction, road salt, root damage, and air pollution. Upper branches are usually the first to go, and once decline begins, secondary fungi and insects speed the process along.

I’m not sure about my tree, though, because its lower branches were the first to go. Also, the tree grows along the back edge of my property, where it’s been shielded from those usual causes for decline.

One more contributor to decline is overtapping. I plead not guilty. My fading tree was larger than the 8 or10 inch minimum diameter for tapping, and I only tapped it once, when the tree, it turned out, was already going downhill. The lack of sap flow was what prompted me to see all this. And then I noticed many rows of sapsucker holes in the bark.

Long story short: The tree became firewood.

My three other, healthy maples might yield me only a quart of finished syrup. The reasons? One quart is enough for me, so I’m tapping only one of them. Also, they’re relatively young. I planted those three trees about 25 years ago, and they’re now only about 8 inches in diameter.

I highly recommend planting trees, for their beauty, for what food they might offer, and for the mere satisfaction of watching the plants grow. Especially if they are small when planted. Small trees also establish quickly to require less aftercare, often soon outgrowing their initially larger compatriots. Those three maple trees? From one perspective, it seems like a long time ago that I dug holes and set the saplings in the ground; from another perspective, it seems like I planted them, walked away, then turned right around to find that these young ‘uns have grown into bona fide trees!

Birch Sap

I may end up with more sap than planned, but not maple sap. Along with the three sugar maples I planted way back when, I also planted three river birches (Betula nigra). They grow, appropriate to their name, in a wet area just out of a swale through which water runs in spring, each a clump of a half dozen or so sturdy trunks reaching skyward to about 35 feet.

Maple might be the heaviest sap producing tree, but it’s not the only kid on the block. Many people tap their black walnut trees. Call me provincial, but black walnut syrup, much as I love the nuts themselves, has no appeal me even though I’ve never tasted it.

Birch syrup though . . . mmm. Never tasted that one either, but it sounds good. Three birch taps should offer an ample amount for tasting.

What a Funny Name

I don’t need to see the small, pebbly-skinned, orange orbs on grocers’ shelves to know that it’s kumquat season. My own Meiwa kumquat is looking very pretty, with a good crop of fruit staring out from their backdrop of glossy, forest-green leaves. I’ve trained the plant as a “standard,” that is, as a miniature tree with a crown of branches perched atop a four foot trunk.

The present crop is my best ever, and traces its success back to last spring. In previous years, I was too timid with pruning. And pruning is necessary, every year. Pruning keeps the plant from growing disproportionately large for its pot -– or my house — and coaxes growth of new, fruiting wood.

The roots also get pruned each year to make space for new potting soil for root growth and nutrients. I laid down the plant and pot to easily slide out the root ball. After slicing an inch or two of roots and potting soil from all around the outside of the root ball, back into the pot the plant went, with new potting soil packed in the space between the shaven root ball and the inside edge of the pot. The seemingly brutal treatment took place last year just as the garden awoke in yellow blossoms from daffodils.

As soon as weather warmed, new sprouts began to grow. By midsummer, the plant was fragrant with blossoms. By late summer, little, green fruits were forming which, with careful watering, survived the environment change as the plant moved indoors in October. The plant stood at attention in a sunny window in the cool bedroom for weeks, and a couple of months ago, the fruits started turning orange. They are now ripe and delicious!

THANKS

February 17, 2021/11 Comments/in Fruit, Gardening/by Lee Reich

I’d like to highlight, today, what makes this blog possible.

First of all, it’s you, readers. The positive feedback I get is very rewarding. I’ve had great opportunities — academically and “in the field” — to learn about growing plants and caring for the soil, and have put all this into practice for decades. My hope is that in entertaining you with all this, your tomatoes, apples, zinnias, and all the rest grow healthier and tastier or prettier. I appreciate the positive (even the sometimes negative) comments from you all.

Second, if you’ll look at the bottom right corner of my blog posts (or scroll way down near the end on a mobile device), you’ll see some banner ads. Nothing flashy or moving or obnoxious in any other way. Just simple links to a few advertisers.

These seven advertisers are special; these are companies whose products I stand behind. I’ve used them and can attest to their quality.

Fruit Plants Galore

Uncommon Fruits of Fall

Uncommon fruits of summer

Take, for instance, Raintree Nursery and Cummins Nursery. I’m a “fruit nut” (and a “nut nut”) and, except when I propagate my own plants, these two nurseries are my go-to nurseries for fruiting trees and shrubs.

Raintree Nursery stands out for the wide variety of common and uncommon fruits they offer, everything from apples to jujubes to musk strawberries to wintergreen to hardy passionfruits. All top quality plants.

Heirloom apples

Cummins Nursery also offers top quality plants, trees in this case. Steve Cummins, the present owner, started the nursery with his dad, Jim, and other family members. Back in the 20th century, when I worked in research for Cornell University, Dr. Jim Cummins also worked there. For many years, he was the rootstock breeder. (A rootstock, on which a Honeycrisp, Mutsu, or other variety of fruit is grafted in order to propagate it, can impart special qualities to the resultant tree, such as early production, eventual tree size, pest resistance, and tolerance to poor soil conditions.)

So I turn to Cummins Nursery if I’m interested in a common (vs. uncommon) fruit tree on a special rootstock, with many, many varieties of fruit to pick from. Or if I want to purchase a rootstock to graft myself. Or if I want a scion of any one of the many, many different varieties of fruits grown at Indian Creek Farm, the pick-your-own farm they run adjacent to the nursery.

You’ll note that Raintree Nursery is in Washington state and Cummins Nursery is in New York state. No matter. These nurseries are selling named varieties of fruit plants. A McIntosh apple grown in Washington state is genetically identical to that variety grown in New York state, so will have the same cold-hardiness, pest resistance, and other characteristics. Of course, a particular season’s weather, wherever the tree is planted, could influence flavor and texture.

Essential, Quality Tools

If you grow fruit plants — or vegetables or ornamentals or houseplants — you’re going to need certain tools. Glance down, then, to my next three advertisers: OESCO (“Oesco” is the acronym for “orchard equipment supply company)”, ARS (the exclusive agent for ARS pruning tools), and Scythe Supply Co.

Whether it’s pole pruners, pruning saws, or most other pruning tools, ARS are among my favorites, and especially for hand shears. The ARS website shows the complete line of ARS tools, as well as where you can purchase them.
ARS web page
One place for many of those pruning tools, ARS or otherwise, is OESCO. And much more. Trowels, all sorts of shovels, hedgers, sharpeners, grafting knives and sealants, stuff for making trellises, and, of course, many kinds of hand pruning shears.
OESCO web page
Scythe Supply Co is where I purchase all my scythe blades, sharpening stones, peening tools, and, originally, my snath and grips (I’ve since made these last two parts myself, when needed). You might think a scythe to be an archaic tools. Not so; it works even early mornings without waking the neighbors and in ground too wet or grass too high for a mower. Swinging a scythe is a meditative, first-class exercise.
Scythe Supply Co, webpage
My property was originally a mere 3/4 of an acre. Besides my home, vegetable garden, and fruit trees, I was able to dedicate a portion of that property to a mini-hay field, where I let the grass grow high and then periodically scythed it as food for my compost pile. It was decorative and functional. (Okay I did encroach on the actual hayfield bordering my 3/4 of an acre; I eventually bought it and now have a bona fide hayfield, portions of which I scythe.)

Two More Essentials

You might wonder, “What’s with Bobbex and Sensorpush?”, the last two ads on these blog pages?”

Bobbex webpage

In the past couple of winters as Daisy and, especially Sammy, matured beyond their super energetic puppy stages,

deer have taken note and become bolder. My initial testing of Bobbex, a deer repellent, seemed promising. I’ve since become amazed at its effectiveness. Deer are here, but not feeding on any of my sprayed plants. And spraying is only needed once a month.

I’ve waxed enthusiastic about Sensorpush many times here on this blog. Basically, it’s a one inch square by 1/2 inch device that you place wherever you want to know the current and historical temperature, relative humidity, barometric pressure, dewpoint, and vapor pressure deficit. There’s one in my greenhouse, and it can alert me if the temperature goes above or below whatever temperature specified. The one on my garden gate is especially useful in spring and fall, when frosts threaten. As soon as the snow melts, my third Sensorpush will go beneath the pile of leaves protecting a fig tree I planted outdoors to monitor winter temperatures there. (Much more about this at a later date.)

So there you have it: seven companies whose products, in my opinion, make for better gardening or farming.

Get Ready for Spring

Are you interested in having a weedless garden this season? Learn how, at my upcoming WEEDLESS GARDENING webinar.

FROM GROCERS’ SHELVES TO MY FLOWER POTS

January 27, 2021/6 Comments/in Fruit, Houseplants/by Lee Reich

Exotic, tropical fruits are turning up more and more frequently on grocers’ shelves these days: dates, papayas, guavas, and others. I look upon these fruits opportunistically, because within each lies dormant seeds that can be coaxed to become exotic, if not beautiful, indoor plants that might even provide a delicious fruit harvest. Such plants provide a break from the humdrum of spider plants, philodendrons, and Swedish ivies.

Seeds of tropical fruits usually germinate best if planted as soon as the fruits are eaten. Cold-climate fruits, in contrast, have innate inhibitors that prevent seed germination until they feel that winter is over.

So all that’s necessary to grow most tropical fruits is to wash their seeds and sow them in potting soil, using the old rule of thumb of burying a seed to twice its depth. And then wait.

DELICIOUS, BUT HARD TO SAY

I have harvested fruit grown from the seed of a grocery store bought pineapple guava, also known as the feijoa (pronounced FAY-HO’-A, from the generic part of its unwieldy Latin name, Feijoa sellowiana, recently change to Aca sellowiana). The fresh seeds, scooped from the fruit, germinated and grew.
Feijoa fruit
Feijoa seems to me an ideal plant to grow. Even outdoors where it’s native, the tree is small, so does not mind being kept five foot high in a pot which can be carried indoors during our frigid winters. The plant is subtropical rather than tropical, so can stand a bit of cold, down to about 10 degrees Fahrenheit.

Feijoa has leaves which are shiny and dark green on their upper surfaces, and felt-like and silvery on their lower surfaces. My plant spends winter decorating a sunny, south-facing window in a cool room in my house. The flowers’ stamens are arranged in a tuft like a red bottlebrush, and the petals are thick, purple and white. Those petals are very edible and very delicious, with a sweet, pineapple-minty flavor.
Feijoa flower
But best of all is the fruit itself. Beneath the thin skin is a gelatinous center with a spicy pineapple flavor. My feijoa plant hasn’t provided sufficient harvest to satisfy my feijoa-ish needs.

A LONG TIME TO WAIT FOR A DATE

The waiting period for a date fruit can be a long time, even a long time for the seed to germinate. But stop for a moment and think about deserts, where dates are native. Should a date seed send up a leafy shoot with the first hint of moisture? Of course not. The dry desert air would dehydrate the sprout in short order. When a date seed germinates, first its thick taproot grows straight downwards, seeking permanent moisture, long before even a small sprout appears aboveground.

I once planted some date seeds (first making sure they came from unpasteurized dates). Knowing that I would have a long wait before the first sprouts emerged, I planned to watch the roots grow to keep myself from becoming too impatient. I put an inch of water in the bottom of a peanut butter jar, slid a tube of rolled-up blotting paper (watercolor paining paper would probably also work well) into the jar, and then “planted” the date seeds halfway up the jar, pressed between the glass and the paper.

As predicted, the roots appeared and thrust downwards before there was any sign of a shoot. When I eventually became bored watching the progress of the roots, I planted the seedlings in potting soil.

Leaves finally did poke up through the soil, an event that was far from dramatic. Each emerging seedling looked like a green toothpick stuck into the soil. In time, the “toothpicks” did unfurl into a succession of fan-like leaves which would match any ordinary houseplant for beauty and tolerance of neglect.

Fruit production from a homegrown date palm is well-nigh impossible. The plant grows slowly. Climate here in northeastern U.S. is suboptimal, to say the least. And only female plants produce fruit, so enough plants would have to be grown to flowering size to ensure at least one male (for pollination) and one female (for fruit).

PA-PA-PAPAYA

One winter day a number of years ago, I planted seeds from a papaya fruit I had just eaten. Having seen papayas growing wild throughout the tropics, I assumed they would not be hard to grow. I scooped the seeds from the fruit, washed them to remove their gelatinous coating, and sowed them immediately.

Growing papayas proved as challenging as growing dates. In this case, not only were the seeds slow to germinate, but the young seedlings were extremely fragile and subject to damping-off. I nursed a single survivor beyond this wimpy initial stage, and, in time, it began to grow robustly.

Potted papaya at Chanticleer

In the tropics, papayas are short-lived trees that often bear their first fruits as early as eleven months after seed is sown. My papaya tree was outgrowing its one-foot-diameter pot when warm weather arrived, so I decided to plant it outside and hope for fruit. Imagine the astonishment of my neighbor, who grew up in Florida, when he saw a tropical papaya tree in my garden!

Unfortunately, my plant succumbed to the first fall frost before it had a chance to fruit. Fruiting would have been chancy anyway, because papaya plants come in various combinations of sexes. Some plants have only male flowers; others only female flowers; and still others have bisexual flowers. Papaya have been known to switch their sex under certain conditions. To fruit, my single plant would have needed bisexual flowers, which remained so.

The feijoa, date palm, and the papaya take their place in the long line of avocados, prickly pears, tree tomatoes, kumquats, lemons, tangerines and other forgotten grocery store plants that once were and, in some cases, still are part of my indoor jungle.

ALMOST LIKE SUMMER

December 30, 2020/17 Comments/in Flowers, Fruit, Houseplants, Vegetables/by Lee Reich

Fresh Veggies

When I was a child, it seemed that winter vegetables were mostly peas and diced carrots, conveniently poured frozen out of plastic bags into pots of boiling water. Yuk! Winter notwithstanding, my backyard garden still offers plenty of fresh winter vegetables. Let’s have a look. Kale, of course, looks unfazed by snow and plummeting temperatures. Not only does it look unfazed; it also tastes very delicious.

More surprising is the endive that I planted back in August, then covered beneath a “tunnel” of clear plastic and slightly insulating row cover held aloft by metal hoops in late October. Temperatures about a week ago went as low as -8° Fahrenheit! Thanks to the additional insulation from almost a foot of snow, now melted, the endive is still lush and tasty.

The rest of winter’s fresh garden vegetables are not in the garden. Most are in plywood boxes in cold storage, first in my mudroom, then moved out to my cooler. vegetables of winter (The cooler is an insulated room cooled with an air conditioner that has been tricked, with a device called CoolBot, into bringing the temperature down just below 40° F.) One box houses Hakurei turnips, Watermelon radishes, and Daikon radishes picked around the middle of December.

The same day I pulled the turnips and radishes, I also dug up leeks, now nestled into another box. With snow cover, both leeks and turnips probably would survive winter out in the garden, but reaching into a box is easier than chopping through ice and snow out in the garden to get at these vegetables.

Yet another box has a few heads of cabbage, also harvested that day in December. Lopping off the outer leaves, which anyway were looking ragged and slug-eaten, cuts water loss from the tight heads and keeps them fresh. One more box is packed full of napa type Chinese cabbages, good for “Asian slaw” or stir fry.

Most years I would have braids of onions also. Not this year. Crop failure. All the onions, both direct-seeded and grown from my transplants, didn’t grow large enough to bother storing. The problem was a clog, too long undetected, in the water line to the seasonal irrigation pump at, evidently, a critical time in onion bulb development.

(I also have a 400 square foot greenhouse packed full of fresh, growing lettuce, mustard greens, arugula, celery, claytonia, kale, chard, and mâche, with a little fresh dill, cilantro, and parsley. But that’s a whole other story.)

Summer Berries

I may be addicted to blueberries. I now eat them pretty much every morning year ‘round. That’s fresh blueberries beginning at the end of June, and frozen ones from mid-September on. I pace myself. The frozen blueberry season opens with about 70 bags (each bag about 5 cups) in the freezer, enough to keep us “berry happy” on into June.
Blueberries, frozen and defrosted
I highly recommend planting blueberries. They are easy to grow organically, the plants are beautiful, and the berries are very healthful and taste great. They’re also easy to freeze: Just spread them on a tray until frozen, then pack them into bags. Their two main requirements are suitable soil, easily made so, and protection from birds, with netting. Each bush will net you 8 pounds, or more, of berries.

Thawed in the refrigerator, the berries taste as good as fresh ones. Or maybe I believe that only because in late December it’s been so long since I’ve had a fresh blueberry.

Olfactory Romance

Man cannot, of course, live by bread alone. I could use some fragrance, some olfactory hint of spring — or summer, or fall. Years ago, I grew “many-flowered jasmine” (Jasminium polyantha). A misnomer for my plant. Its fragrance was heavenly but it only coughed up a few blossoms each winter, despite my subjecting it to a period of temperatures below 60 degrees F. and some drought to give it a rest before it (was supposed to) burst into flowering abundance.

Gardenia was another one of my plants for winter fragrance. It did bloom in winter, late winter, and its fragrance was heavenly. But it proved to be a magnet for scale insects, one of the most difficult house plant pests to control organically. Both plants have long ago been composted.

I’m now eagerly awaiting blossoms on my Meyer lemon plant. The plant is easy to bring into bloom, and there’s the added bonus of delicious lemons. Being a hybrid of lemon and sweet orange, Meyer lemon has a slightly different flavor from that of lemons.
Meyer lemon tree in pot
The other plant to — reliably, I hope — blossom now, in early winter is sweet osmanthus (Osmanthus fragrans), specifically the variety Goshiki. Why Goshiki? Because it has variegated leaves, green and white with splashes of pink, spiny like those of holly. It’s cold-hardy to Zone 6. My plan is to grow it in a pot to bring indoors to a cool sunny window in late fall to spend the winter.

This is all a pipe dream so far because all I have is a spindly stem I cut to root from a plant beckoning me from a sidewalk near Philadelphia. The cutting doesn’t look hopeful. The quest begins.

SNOW’S COME AND SO HAS FRUIT

December 23, 2020/8 Comments/in Fruit, Soil/by Lee Reich

Free and Attractive Mulch

Beautiful. Floating down from the sky. A white blanket of “poor man’s manure.” That’s what gardeners and farmers have called snow.
Garden under snow
In fact, snow does take some nitrogen from the air and bring it down to ground level for plant use in spring. Not that much, though. Just a few shovelfuls of real manure could supply the same amount of nitrogen as a blanket of snow.

Mostly, what I like about the 15 inch deep fluffy whiteness now on the ground is the way it insulates what’s beneath it. Fluctuating winter temperatures wreak havoc on plants, coaxing them awake and asleep and awake and asleep as air temperatures go up and down and up and down. Each time plants are awakened, they become more susceptible to subsequent cold, the whole problem exacerbated with borderline hardy plants.

Anticipating cold weather and snow, last fall I cut back a cardoon plant and two artichoke plants, covered each with a large, upturned plastic planter, and then smothered everything in autumn leaves. Cardoon and artichoke, in fall with leafy cover Both kinds of plants are probably cold-hardy to about zero degrees Fahrenheit, but here winter temperatures, except last winter, typically drop to about minus 20 decrees Fahrenheit. That snowy blanket provides extra protection that the plants might need — especially after last Saturday’s unseasonal low of minus 8 degrees. Cardoon and artichoke, snow covered

Hardy orange (Citrus trifoliata) is another plant to benefit from snow cover. It’s a Citrus that’s allegedly cold-hardy into zone 5 (-20°F minimum temperature). I planted some seeds outdoors a few years ago and, while their roots survive winter cold, the tops die back to resprout each spring. I also planted out a more mature hardy orange that was given to me; it also suffered some cold damage.

The deeper this winter’s snow and the longer it stays deep, the more of the hardy oranges’ stems will survive till spring. Perhaps, helped along with global warming, enough of the above ground parts of the plants will survive to reward me one year with sweet-smelling blossoms and, less appealing, their very puckery fruits.

Multiplying Currants and Grapes

Last fall, I cut stems from my black currants and grapes into 8 inch lengths. In the bare ground between some dwarf apple trees, I scratched some lines and pushed a straight-bladed shovel into the ground on that line. Levering the handle of the shovel opened up just enough space in which to shove one or two of those cut stems, distal ends up, right up to their topmost buds. Then I moved along the scratched line, pushed the shovel in again, shoved in more stems, and so on down each line. If all goes well, each of those stems will grow into a good sized plant that I can dig up and transplant next autumn.
Rooted currant cuttings
That is, unless alternating freezing and thawing of the soil heaves those stems up and out of the ground. I’ve seen it happen, leaving a row of carefully inserted stems sitting on top of the ground by winter’s end.

All of which is another reason I’m thankful for the snow. In addition to protecting plants from cold, the blanket modulates soil temperatures, keeping cold soil cold, which is how I’d like it to remain until spring. I could have — should have — thrown some fluffy, organic mulch, such as leaves or straw, over the stems to do the same thing. But I didn’t. I hope the snow stays.

Where One Plus One Does Not Equal Two, Figuratively Speaking

The harvest has begun: I picked the first fruit of the season this week. Not only that, but it was the first fruit I harvested from the particular plant. The fruit was a Sunquat, planted in a pot a year and a half ago. It summers outdoors and winters indoors, basking in sunlight streaming through a south-facing window.

Not many people have heard of Sunquats. I hadn’t. Citrus plants hybridize freely and Sunquat is one of many citrus hybrids, this one a mating of kumquat (Citrus japonica) and Meyer lemon. I happen to be a big fan of the tart flesh and spicy, sweet skins of kumquat fruits. I also happen to be a big fan of Meyer lemon, which is not a true lemon but is probably a hybrid of lemon and sweet orange.

Meyer lemons are juicy and somewhat sweet, with a flowery aroma. They also bear prolifically. As testimonial to their precocity, I once had a cutting that flowered soon after rooting, when it was only a few inches tall.
Meyer lemon cuttings rooted

So what could be bad about combining kumquat and Meyer lemon? A Sunquat! The skin was sour without picking up any of the spicy tang of a kumquat’s skin. The flesh was much less puckery than kumquat or lemon, but was uninteresting, just bland. Perhaps harvesting a bit underripe, before the skins turn full yellow, will put some pizazz in a Sunquat.

If not, I’ll stick to growing Meyer lemons and kumquats, each on their own and with their own delectable flavor.

CLOSING “SHOP”

Chips, Not Hay, In This Case

“Make hay while the sun shines.” Good advice, literally in agriculture and figuratively in life. And I’m following it these days, in agriculture. Not making hay of course, because that sunshine is only effective in summer and fall, partnered with heat.

The “hay that I’m making” is actually mulch that I’m spreading. A few weeks ago I put my “WOOD CHIPS WANTED” sign out along the road in front of my house. In a short time, an arborist was kind enough deposit a truckload of chips. I figured I could spread it on the ground beneath some of my trees and shrubs, especially the youngest ones. There, next summer, the mulch would keep weeds at bay, slow evaporation of water from the ground, and feed soil life, in so doing enriching the soil with nutrients and organic matter.

Usually, by this time of year, my piles of wood chips have frozen solid or are white mounds beneath snowy blankets. Not so this year.

So I’ve been loading up garden cart after garden cart with chips to haul over to the garden. (Once the ground disappears beneath a heavy, white layer of snow, moving heavy cartloads becomes nearly impossible.)

Since the most important trees and shrubs had already been mulched earlier in autumn, I decided it was a good time to add a layer of chips to the paths in the vegetable garden. Mulching chestnut trees Chips there are mostly to suppress weeds which thrived with last season’s unusually abundant rainfall and to soften, by spreading out, the impact of footfall on the paths. I generally “chip the paths” every couple of years at a minimum if for nothing more so that the height of the paths keeps up with the rising height of the vegetable beds which get — and already got, at the end of this season — a one-inch deep blanket of compost annually. (Besides the usual benefits of mulches, the compost provides enough nutrients for the intensively planted vegetables for the whole season. No fertilizer per se is needed.)

After decades of my adding an inch or more of wood chips to the paths and compost to the beds, you might suppose that the whole vegetable garden has risen a few feet above the surrounding area like a giant stage. Nope. The goodness of organic materials, such as the compost and wood chips, comes from soil organisms chewing them up and breaking them down. As decomposition takes place, the bulk of these materials, which are mostly carbon, hydrogen, and oxygen, is released into the air as carbon dioxide and water. The minerals that remain feed the plants.

Pine Berries?

One bed in the vegetable garden is home to strawberries. That bed also needs mulching, for different reasons and with different materials than the other beds, and needs it every year about now.

A strawberry plant is mostly nothing more than a stem, a stem whose distance from leaf to leaf has been telescoped down to create a stubby plant. Drawing of strawberry plant Like the stems of any other plant, a strawberry stem each year grows longer from its tip and also grows side shoots. So a strawberry stem rises ever so slowly higher up out of the soil each year.

Strawberry stems are not super cold-hardy. As a stem slowly rises higher in the ground, it’s exposed to more and more cold, and more apt to dry out.

What’s needed is to protect the stems with an insulating blanket of some loose organic material. Straw is traditional — and one possible root of the name “strawberry” — but good straw reliably free of weed seeds is hard to find. Instead of straw, I often use wood shavings, conveniently available in bagged bales. This year I decided that the giant pine tree here could spare a few pine needles, raked up to share with the strawberries.

The goal of mulching strawberries isn’t to keep cold out, just to moderate the bitterest cold. Strawberry bed mulched with pine needles Mulching too early might cause the stems to rot. I typically wait until the ground has frozen about an inch deep which usually occurs towards the end of December here, and then cover the plants with about an inch depth of wood shavings.

Come spring, the mulch needs to be pulled back before the plants start growing. Tucking the mulch in among the plants provides the usual benefits of mulch, especially important for strawberries because of their shallow roots, and provides a nice, clean bed on which the ripening berries can lie.

(More about growing strawberries can be found in my book GROW FRUIT NATURALLY.)

Hey, Good Looking

I admire the look of my vegetable gardens this time of year. With the chipped paths and compost lathered beds, some also with a tan cover of winter-killed oat plants, they look very tidy and ready to welcome new seeds and transplants in the months ahead. The look doesn’t compare with the lush greenery and colorful fruits of the summer garden, all of which is nothing more than a memory.

FINAL HARVESTS

December 9, 2020/10 Comments/in Books, Fruit, Vegetables/by Lee Reich

Compressed Gardening Experience

People are so ready to sit at the feet of any long-time gardener to glean words of wisdom. I roll my eyes. Someone who has gardened for ten, twenty, even more years might make the same mistakes every year for that number of years. I, for instance, swung a scythe wrong for 20 years; I may have it right now. Even a wizened gardener who has evaluated and corrected their mistakes has garnered experience only on their own plot of land; these experience may not apply to the differing soils, climates, and resources of other sites.
Lineup of my books
When I began gardening, my agricultural knowledge and experience was nil, zip, niets, rien, nada. But — and this is important — I had easy access to a whole university library devoted solely to agriculture. Hungry to learn, I read a lot. (I also was taking classes in agriculture.) In one year I was able to garner years of, if not actual experience, much of the knowledge that comes with that experience. And my garden showed it.

I’ve now gardened many decades and still gobble up the written word.

All of which is to say that reading reputable sources about gardening can make anyone a much better gardener and do so quicker than by gardening alone. “Reputable” is a key word in the previous sentence. So here’s the, to use the phrase of Magliozzi brothers on the radio show Cartalk, Shameless Commerce Division of this blog: a plug for my books. I stand firmly by anything I’ve written and am open to criticism.

Here’s the book list, all available from the usual sources or, signed, from me through this website (good gift idea, also):

•A Northeast Gardener’s Year: A month by month romp through all things garden-wise, what to do, how to do it, and when to do it.
•The Pruning Book: Plant responses, pruning tools, how to prune just about every plant (indoor, outdoor), and final sections on specialized pruning techniques, such as scything and espalier.
•Weedless Gardening: A four-part system, emulating Mother Nature and based on current agricultural research, that makes for less weeds and healthier plants, along with other benefits such as more efficient use of water and conservation of humus.
•Landscaping with Fruit: Following introductory chapters about designing your landscape is a listing of the best fruits to use for “luscious landscaping” in various regions and how to grow each of these fruiting trees, shrubs, vines, and groundcovers.
•Grow Fruit Naturally: Describes multi-faceted approaches to growing fruits without resorting to toxic sprays, starting with selecting kinds of fruits and varieties and moving on to encouraging natural predators, beefing up the soil, and more.
•The Ever Curious Gardener: Using a Little Natural Science for a Much Better Garden: Knowing some of the science behind what’s going on in the garden can make you an even better gardener; here’s how.

Vegetable Finale

And now, on to some gardening . . .

I’ve said it before and Yogi Berra said it before me, “It ain’t over till it’s over.” Last night’s temperature plummeting to 18°F was still not enough to put the brakes on the vegetable garden. Beneath their covered “tunnels,” arugula, mustard, endive, and napa Chinese cabbage still thrive. Along with mâche and kale, which aren’t under cover, all these greens are looking as perky as ever and, most important, taste better than ever.

Interestingly, temperatures I’ve measured within the tunnels are not that different — actually, not different at all — from temperatures I’ve measured outdoors. But something’s different. The increased humidity under the tunnels is probably at least partially responsible for the fresh tastes and appearances.
Endive in tunnel
It’s a wonder that these tender, succulent leaves tolerate such temperatures. You’d think the liquid in their cells would freeze and burst the contents to smithereens. That would have been the case if the 18°F had come on suddenly, without any precedents.

Plants aren’t passive players in the garden. Increasingly cold weather and shortening days acclimated these plants to cold. (A month ago, temperatures dropped one night to 16°F.) Plants move water in and out of their cells, as needed, to avoid freezing injury. And increasing concentrations of dissolved minerals and sugars in the cells make the water freeze at lower temperatures. Perhaps that’s one reason why these vegetables taste so good. The tunnels also slow down swings in temperature, giving plants time to move water in and out of their cells and whatever else they do preparing for and recovering from cold.

Too many people, even gardeners(!), consider endive as nothing more than a bitter, green leaf best used as garnish. Reconsider. Given close spacing so that inner leaves of each head blanche from low light along with cool and cold temperatures, and endive takes on a wonderful, rich flavor. Blanched interior of endive Only the slightest hint of bitterness remains, enough to make the taste more lively — delicious in salads, soups, and sandwiches.

Fruit Finale

The last fruits of the season, Szukis American persimmon, were harvested last week after over a month of eating them. Definitely the easiest fruit I grow. No pruning, no pest control. And definitely one of the tastiest: imagine a dried apricot soaked in water, dipped in honey, then given a dash of spice.

Fruits were very mushy for the final harvests — perfect for a jam. Squeezing a bunch of the fruits in a mesh bag (such as used for women’s “delicates” in a washing machine) pushed out Making persimmon jam the pulp without seeds. No sweetener needed. Just jar it up and refrigerate (keeps about 2 weeks) or freeze. Delicious.

FROM PAST TO PRESENT

November 11, 2020/4 Comments/in Fruit/by Lee Reich

Br-r-r-r-r-r

This post originally appeared November 7, 2009. Here’s an update with commentaries on how things have changed — and not changed — over the past 11 years.

Dateline: New Paltz, NY, October 19, 2009, 5:30 am. I bet my garden is colder than your garden. I was startled this morning to see the thermometer reading 23 degrees F. Not much I could do at that point about protecting “cold weather” vegetables still in the garden, some covered with floating row covers and some in “plein aire.” The thing to do under these circumstances was wait for the sun to slowly warm everything up and then assess the damage.

2009

I ventured out to the garden for a survey in the sunny midafternoon. Joy of joys. None of the cold-hardy vegetables was damaged by the cold. Romaine lettuces stood upright and crisp, arugula was dark green and tender, radishes were unfazed, and the bed of endive, escarole, and radicchio looked ready to face whatever cold the weeks ahead might offer.

That 23 degree temperature reading came from my digital thermometer, read indoors from a remote sensor out in the garden. Most surprising was the reading from the old-fashioned minimum/maximum registering mercury thermometer out in the garden. This thermometer remembered the night’s lowest temperature as 20 degrees F. Brrrrrrrr.

2020

Dateline: New Paltz, NY, November 11, 2020. This fall has likewise had a few frigid dips in the thermometer, down a couple of times to 24°F, and cold temperature vegetables have likewise fared well. Nowadays I check temperatures with a high-tech, but reasonably-priced, Sensorpush, a small sensor strategically hung in the garden. It beams current temperature and humidity back to my smartphone, and keeps a record of them throughout the day, week, month, and year. Its reporting jives with that of my “old-fashioned minimum/maximum registering mercury thermometer”.

What has changed is the weather over the past couple of weeks, with sunny days and temperatures hovering around 70°F. A fitting closing for a stellar year in the garden: best harvest, best fall color, congenial weather.

The effect of microclimate has been startling. I live about 4 miles out of town, on a road that follows the valley along the Wallkill River. On clear nights, radiation frosts spill cold air downhill to bring the temperature at the farmden about 5° colder than in town. A couple of evenings ago, temperature in town, as displayed on the local bank building and on my car thermometer as I drove through town, was 55°. Arriving at the farmden, the car thermometer, Sensorpush, and the “old-fashioned minimum/maximum registering mercury thermometer” registered 42° — quite a dramatic difference for a 40 foot elevation difference.

Mediterranean Fancies

(2009) Moving, figuratively, to warmer climes: the Mediterranean. I’m taking the Mediterranean diet one step further by trying to grow some of the delectable woody plants of that that region.

Figs are a big success, and not an unfamiliar sight well beyond their natural range. I’ve tried all the usual methods of growing them in cold climates. I’ve grown them in pots brought indoors for winter; I’ve bent over and covered or buried the stems to protect them from cold; I’ve swaddled the upright stems in leaves, straw, wood shavings, or other insulating materials. All yielded some fruit, but none of these methods beats having a small greenhouse with the trees planted right in the ground. Handfuls of soft figs, so ripe that each has a little tear in its “eye,” follow each sunny day and should do so for a few more weeks.

Bay (as in “bay leaf”) also does well, this one potted. After 20 years, my bay laurel is a

Bay laurel, 2009

handsome little tree, trained to a ball of leaves atop a single, four-foot trunk. The fresh leaves are much more flavorful, almost oily, than dried leaves, especially the old, dried leaves typically offered for sale.

(2020) Yes, figs have been abundant in the greenhouse over the past 11 years. But diminishing sunlight and cooler temperatures, even in the greenhouse (37° minimum temperature), have drained the flavor from the few ripe, remaining figs.

After 30 years, the bay is still thriving, valued as much for its beauty as for the flavor of its fresh leaves. It’s still trained as a small tree, smaller than in the past. I lopped the whole plant to the ground a few years ago to give it a fresh start, trained as round-headed tree only thirty inches tall.

Bay Laurel 2020

(2009) Three hopeful Mediterranean transplants are my olive, feijoa, and lemons. I purchased the olive tree in spring, whereupon it flowered and has actually set a single fruit! The feijoa, also known as pineapple guava, has two fruits on it, which might not seem like a big thing except that those two fruits represent the culmination of about 15 years of effort. (More on that some other time.) True, feijoa is native to South America, but it thrives and is often planted in Mediterranean climates. The same goes for lemon, except that it is native to Asia. My Meyer lemon hybrid, like the olive, was potted up this past spring and sports a single fruit.

The long shots among my Mediterreans are pomegranates. My two plants – the varieties Kazake and Salavastki – are cold-hardy, early ripening, sweet varieties from central Asia, so should do well here in a pot. (They are cold-hardy for pomegranates, down to a few degrees below zero degrees F.) They have yet to flower and fruit.

In a few weeks I’ll move all the potted fruits to the sunny window in my very cool basement, where winter weather is very Mediterranean-esque.

(2020) All three trees are still residents here, although the feijoa tenuously so. It’s a pretty plant but what I really want from it is fruit. Yields have been paltry. I’ve repeatedly threatened it with the compost pile, but repeatedly reneged. Besides its beauty, it often flowers, and the flower petals, fleshy, pinapple-y, and minty, are delicious.

One year, in an effort to downsize plant-wise, I was also going to walk the olive to the compost pile. And then someone reminded me that the olive is a symbol of peace, so I kept it. It’s a pretty plant, an easy to care for houseplant, and occasionally bears tasty olives.

The Meyer lemon offers so much everything: deliciously fragrant flowers, verdant leaves year ‘round, and tasty lemons. Just not enough of them. Meyer lemon is actually a hybrid of lemon and sweet orange. Meyer lemon tree in pot

Pomegranate is still a long shot. I’m down to one plant, Salavastki. It often flowers and sets a few fruits, but the fruits drop off. I’m still not sure why.

Still Great After All Those Years

Szukis persimmons ripening on leafless stems

2009

(2009) Persimmon is another tree grown in Mediterranean countries, although it’s not native there. Up here, I grow American persimmon, an outdoor tree that is cold hardy to below minus 20 degrees F.. Besides yielding delectable fruits, it’s a tree that requires almost no care, not even pruning. Some of the tree’s branches are deciduous, naturally dropping in autumn.

Heavy winds of a few weeks ago took the persimmon’s self-pruning theme too far and blew the top off my 20 year old tree. Fortunately, my three other persimmon trees remained unscathed. I’ll just trim the break from the decapitated tree and it will be fine.

2020

(2020) Persimmon is still thriving, still care-free, and still delectable, the ripe fruits tasting like dried apricots that have been soaked in water, dipped in honey, and given a dash of spice. My persimmon “herd” has been thinned to my two best-tasting, most reliable varieties: Szukis and Mohler. Both are well-adapted to ripening in the the relatively short season (for a persimmon) this far north. Right now, the leafless tree is leafless and still loaded with fruit for the picking, much more than I can eat.

GRAPE and NUTS

October 21, 2020/12 Comments/in Fruit/by Lee Reich

Long-term Grapes

About a month ago, I picked a bunch of grapes as I was walking around the farmden with a friend, and handed it to him to taste. “Wow,” he exclaimed, eyes lighting up, “that really has taste.” That was the variety Brianna, one of many I grow that are otherwise not well-known, surely not to anyone who doesn’t grow grapes. My friend and I went on to agree that store-bought grapes are, “at best, nothing more than little sacks of sugary water.”

All that’s history now. Over the past month, most of the remaining grapes have either been harvested, eaten by birds or insects, or rotted, although a few very tasty berries can be salvaged here and there from some ugly bunches still hanging.

But are those grape-ful days gone yet? Years ago I read about how, over a century ago in France, fresh grapes were sometimes preserved by cutting off bunches along with a length of stem, the bottom of which was slid into a narrow-mouthed, water filled bottle. These bottles were then placed in a rack on shelves in cold storage which, where outdoor temperatures rarely dipped below freezing, was nothing more than a slightly insulated, outdoor room.

Grapes, fresh picked

A month ago, I emulated those French grape growers of yore, in this case using Corona beer bottles, three of them, three grape varieties, and my refrigerator — very decorative looking.

Grapes, after 1 month storage

For a modern version, another bunch of grapes went into the refrigerator in a sealed freezer bag. Grapes in freezer bag If any of this worked out, the plan was to use either the old-fashioned or modern method with a whole bunch of bunches in my walk-in, insulated and with some cooling or heating, as needed, fruit and vegetable storage room.

Back in the olden days, storing fresh grapes was not so rare even on this side of the Atlantic. Professor Frank Waugh, in his 1901 book Fruit Harvesting Storing, Marketing, wrote “An acquaintance of mine from the grape-growing district wrote me the other day (March 12th), ‘A neighbor of mine has one hundred tons of Catawbas still in storage.’” Probably not as single bunches on stems in bottles of water!

Anyway . . . drum roll . . . yesterday it was time to taste my stored grapes. One variety, Glenora, didn’t hold up well. The other two, Lorelei and Brianna, were very good. “Bottled” bunches were very slightly shriveled, but tasted quite good. Perhaps they would do better in the more humid atmosphere of the walk-in cold storage room. The bagged bunch, Brianna, was plump and also tasty.

Admittedly, none of the stored bunches had the crisp texture or fresh flavor of the few berries hanging on ugly bunches still outside. But all were better than any fresh grapes I can buy.

Walnuts at the Car Wash

Storage of nuts, also abundant this time of year, is more straightforward. You pick them up from the ground, let them cure in a cool place away from squirrels, then crack and eat them at your leisure.

With black walnuts, the green husks must be removed and the nuts within cleaned up. Leaving the husks to soften and darken a little makes them very easy, although tedious, to remove. Of the many suggested methods, twisting them off with two rubber-gloved hands seems most effective.

As far as cleaning up the hulled nuts, an old fashioned washing machined, earmarked only for this purpose, would work well. I don’t have one, so came up with an effective alternative.

After spreading out all the husked nuts into eight black plastic vegetable harvest boxes, I loaded them in the back of my truck. And then it was off to the car wash. A couple of rounds with the high pressure water spray did the trick. It was a messy job that I was prepared for with rain coat and pants, boots, hat, and face shield. The truck needed a washing anyway.

Spreading out the trays on the deck exposed for a few days to bright sunlight had them all clean and dry. Squirrels would normally be a threat but the deck is also where Sammy and Daisy, my dogs, spend much of their days.

Finally, the nuts were put into five half-bushel baskets for cracking beginning towards the end of December, which is about when last year’s nuts will be finished up.

Harvest Tragedy

I was never that hopeful for English walnuts here (also called Persian or White walnuts). This species is not all that cold-hardy, their blossoms are susceptible to late frosts, which are common here on the farmden, their leaves are susceptible to anthracnose disease, and the only place I had for them was near the road, along the squirrel highway (telephone, cable, and electric wires).

Still, I couldn’t resist, back in 2006, an offer of seeds for some “hardy” varieties. I planted two groups of three trees each, planning to cull out any weaker ones in each group.

All the trees grew well, and I eagerly awaited blossoms which, finally, this year, appeared in abundance. That abundance was followed by an abundance of nuts, and everything looked healthy. Then disaster, in the form of squirrels, struck. Every single nut was stripped from the trees.

Well, not every single nut. One nut was left, which I harvested, easily popped out of its husk, and let sit — cure — on the kitchen table for a couple of weeks. Then, with great fanfare, it was cracked open and eaten.

This year’s English walnut harvest

As luck would have it, I also had a bag of store-bought English walnuts with which to compare in taste. No contest. Store-bought tasted rancid in comparison.

Next year, in enough time before the nuts start to ripen, I plan to spray all the trees with a hot pepper spray.

Any other suggestions would be most welcome.
