PRUNING FOR BEAUTY, FUN, AND FLAVOR

April 29, 2020/16 Comments/in Fruit, Pruning/by Lee Reich

Yew Love

Mundane as she may be, I love yew (not mispelled, but the common name for Taxus species, incidentally vocalized just like “you”). Hardy, green year ‘round, long-lived, and available in many shapes and sizes, what’s not to love? Perhaps that it’s so commonly planted, pruned in dot-dash designs to grace the foundations in front of so many homes.

Still, I love her. For one thing, Robin Hood’s bow was fashioned from a yew branch (English yew, T. baccata, in this case). Two other species — Pacific yew (T. brevifolia) and Canadian yew (T. canadensis) — are sources of taxol, and anti-cancer drug.
Yew berries
At a very young age, I became intimate with yew bushes surrounding our home’s front stoop, on which my brother and I would often play. Yew’s red berries, with an exposed dark seed in each of their centers, would give the effect of being stared at by so many eyes. Sometimes we’d squish out the red juice, carefully though, because we were repeatedly reminded that all parts of the plant are poisonous. (I’ve since learned that the red berries are not poisonous; but other parts of the plant, including the seed within each red berry are poisonous.)

If yew has, for me, one major fault, it’s that deer eat it like candy. Interesting, since grazing on yew can kill a cow or a horse.

Mostly, I love yew because she takes to any and all types of pruning. My father once had a very overgrown yew hedge threatening to envelope his terrace. I suggested cutting the whole hedge down to stumps. Following an anxious few weeks when I thought my suggestion perhaps overly bold, green sprouts began to appear along the stump. A few years later the hedge was dense with leaves, and within bounds.

Although usually pruned as a bush, yew can be pruned as a tree. A trunk, once exposed and developed, has a pretty, reddish color. Deer sometimes take care of this job, chomping off all the stems they can reach to create a high-headed plant with a clear trunk.

As an alternative to being pruned to dot-dash spheres and boxes, yew hedges can be pruned to fanciful shapes, including animals, or “cloud pruned” (niwaki, the Japanese method of pruning to cloud shapes). Many years ago, I followed the herd and planted some yews along the front foundation of my house, pruning them to one long dash. No dots.
Yew caterpillar
Since then, I’ve converted that hedge to a giant caterpillar and, more recently, tired of the caterpillar and attempted to cloud prune it, not with great success so far. (It’s my shortcoming as a sculptor, not the plant’s fault.) The goal in this case is not the kind of cloud pruning with clouds as balls of greenery perched on the ends of stems. My goal is to blend the four plants together as one billowy, soft cloud.

Facing my kitchen window is another yew, a large one that was planted way before I got here. Its previous caretaker, and up to recently I, have maintained it as a large, rounded cone. Last year I decided to make that rounded cone more interesting, copying a topiary in Britain. The design is in its early stages, awaiting some new growth this year to fill in bare stems now showing in interior of the bush.

Not Too Late for Peaches

Moving on to more pragmatic pruning . . . peaches. No, it’s not too late. In fact, the ideal time to prune a peach tree is around bloom time, when healing is quick. This limits the chance of stem diseases, to which peaches are susceptible.

Peach tree, before pruning

Peach trees need to be pruned more severely than other fruit trees. As with other fruit trees, the goals are to avoid branch congestion so remaining branches can be bathed in light and air, to plan for future harvests, and to reduce the crop — yes, you read that right — so that more energy and better quality can be pumped into remaining fruits.

To begin, I approached my tree, loppers and pruning saw in hand, for some Sawing peach limb major cuts aimed at keeping the tree open to light and air.

Peaches bear each season’s fruits on stems that grew the previous season. So next, with pruning shears, possibly the lopper, in hand, I went over the tree and shortened some stems. This coaxes buds along those stems to grow into new stems on which to hang next year’s peaches.
Shortening peach branch
And finally, I went over the tree with pruning shears, clipping off dead twigs as well as weak, downward growing stems. They can’t support large, juicy, sweet fruits.

Done. I stepped back and admired my work.

Spring: A Manic Time in the Garden

April 22, 2020/23 Comments/in Flowers, Fruit, Planning/by Lee Reich

The Season’s Ups and Downs

To me, spring can be a manic time of year. On the one hand, no tree is more beautiful or festive than a peach tree loaded with pink blossoms. I’d say almost the same for apples, pears, and plums, their branches laden with clusters of white blossoms.
Peach tree in bloom
And it’s such a hopeful season. If all goes well, those blossoms will morph, in coming months, into such delicacies as Hudson’s Golden Gem and Pitmaston Pineapple apples, and Magness, Seckel, and Concorde pears. My peach tree was grown from seed, so has no name. With all this beauty and anticipation, I can periodically forget the pandemic that’s raging beyond my little world here.

But even as my eyes feast on the scene and I forget about the pandemic, I can’t forget about the weather’s ups and downs. Specifically, the temperature: Frosty weather has the potential to turn blossoms to mush and ruin the chances for fruit. Especially on my farmden, here in the Wallkill River valley. As in other low-lying locations, on clear, cold nights, a temperature inversion occurs, with heat radiated to the clear sky making ground level temperatures low. Cold air is denser than warmer air, so all the cold air flows down slopes to collect in valleys.

There’s not much to do to avert that frost damage. A blanket thrown over a tree would help but my trees are too large and too many. Branches could be sprayed with water; water, in transitioning to ice, releases its heat of fusion as long as it’s continuously applied. A helicopter or a “wind machine” could dilute colder air at ground level with warmer air from higher up. These methods might be used commercially but, to quote the sage of Newburgh (that’s another story), “That’s not gonna happen” here.

Therapy, a Plan

Rather than worrying myself into the manic phase of spring, I’m going to assess the damage and live with it. For starters, I need to know the temperature.

I have been using is a nifty little device called Sensorpush, a 1-inch square cube, perhaps a half-inch thick, that I have mounted outside and that continually transmits the temperature to my cell phone. Sensorpush receiver Great. Even better, temperature (as well as humidity) is recorded, and can be displayed graphically or downloaded to my computer. So I didn’t have to be awake to find out the mercury hit 32.5°F at 12:16 AM on the night of April 17th and stayed there until it began rising around 7 AM.
Sensorpush readout
Fortunately, researchers have compiled temperatures at which damage to blossoms occurs. Specifically, damage enough to wipe 10% of the crop, and damage enough to wipe out 90% of the crop. And more specifically, applying those numbers to various kinds of fruits, which vary in their blossom’s cold tolerances. And even more specifically to the various stages of blossoming for each kind of fruit. Generally, less cold is required to kill a blossom the closer it is to bloom time.

Here is a chart compiled and photographed by Mark Longstroth of Michigan State University:
Critical temperatures for fruit buds

So now I can take this information, couple it with data recorded by Sensorpush, and foretell my sensory future, pomologically speaking. Below freezing temperatures since trees awakened have been 24° on April 17th, 27° on April 19th, and 26° on April 21st. Of course, it ain’t over till it’s over, and the average date of the last frost here is about mid-May.

Peach bloom

Plum blossoms

My plum trees were in full bloom on April 13th, at which time the blossoms are susceptible to 10% kill at 28° and 90% kill at 23°. That makes only 10% loss. The peach tree was also in bloom on that date, and is very similar in it’s blossom’s cold tolerance, so only 10% loss there also, so far.

Asian pears were showing “first white” and “full white” on April 19th, when the low hit 27°. That temperature would cause them no damage. The same would be true, going forward, for subsequent temperatures above 27°. The Europeans should be fine because today, April 21st, they are in tight cluster, and cold hardy to 24°.

Asian pear full white

European pear tight cluster

Apples also are fine, also in tight cluster so, according to the chart, undamaged by temperatures above 27°.

Apple blossom tight cluster

And a Sprinkle of the Unknown

All this seems very science-y comforting, and it is. As with most garden science, though, things are more complicated, to some extent, than can be easily predicted. For one thing, some variation in cold hardiness undoubtedly exists from one variety to the next. In the case of my trees, I have an American hybrid and some European hybrid plums; they might more generally differ in blossom hardiness. And what about the length of time at a given temperature, and the effect of humidity?

Overall, the chart has calmed me down. Not to mention that a certain amount of fruit loss would be a good thing. A tree has just so much energy, and too big a crop makes for less flavor and size. Only 5% of blossoms of an apple tree need to set fruit for a full crop.

Now, I can move on to worry about insect and diseases that might hone in on my fruit.

Pruning, Flowers

February 27, 2020/14 Comments/in Flowers, Fruit, Pruning/by Lee Reich

Much of Pruning is About Renewal

Why am I spending so much time pruning these days? To keep plants manageable and healthy, of course. But also so that flowering and fruiting trees, shrubs, and vines keep on flowering and fruiting. “Renewal pruning” is what does this.

Pruning apple spur

As plant stems age, they — like all living things — become decrepit, no longer able to perform well. But any plant’s show or productivity can be kept up if stems that are too old are periodically lopped back, which promotes growth of new, young, fecund stems. That’s all there is to renewal pruning.

Ah, but the devil is in the details. One important detail is how old is “too old.” That depends on the flowering and fruiting habit of the plant.

Near one extreme would be pear trees. Along pear stems grow stubby growths, called “spurs,” which bear the tree’s flowers and fruits.

Young pear spur

Older pear spur

These stubby growths grow only an inch or less each year. Over time, spurs branch and these small branches, in turn, branch to create what look like miniature trees perched along the tree’s stems.

A pear’s individual spur can remain vibrant for about a decade, so little pruning is needed annually. But eventually, even a spur grows old and decrepit. I renewal prune my pears by cutting back some of the stubby parts of a spur system to coax out younger stubby growths or even by lopping back a whole stem on which they sit, stimulating new stem growth on which will develop new spurs.

Near the other extreme in pruning would be an everbearing raspberry plant, which bears flowers and fruits on young shoots arising from ground level. Those bearing stems are very short lived. One way to prune an everbearing raspberry plant would be to lop all stems to the ground each winter. Having borne, those stems are aging rapidly, and pruning stimulates a flush of new, bearing stems that will come up from ground level in spring.

Everbearing raspberry growth habit

(Not to muddy the waters, but everbearing raspberry stems actually bear late in their first summer of growth, then again in midsummer the following year, so stems could be left one more season to bear that second crop. After that, though, the two-year-old stems need to be cut back. They die after their second year anyway.)

Pear and everbearing raspberry represent two extremes in bearing habit and, hence, method of renewal pruning. Other plants lie somewhere on the spectrum between these extremes. Where? It depends, as I wrote, on their particular bearing habit. For instance, blueberry stems are most productive on stems up to 6 years old, gooseberries on stems 2 and 3 years old, and grapes and peaches on stems one year old. So I cut away stems older than 6 years old from my blueberry bushes, stems older than 3 years old from my gooseberry bushes, and stems older than a year old from my grape vines and peach trees.

For other plants grown for either their flowers or their fruits, find out how to renewal prune them by watching how they bear for a season or more, or get the information from a book (such as my book, The Pruning Book).

A Workshop

If you’re interested in delving deeper into pruning, I will be holding a pruning workshop here on my farmden in New Paltz, NY on March 28, 2020. For more information about this workshop, please go to https://leereich.com/workshops.

Not Forgetting the Flowers

Flowers are at a premium this time of year. Here on my farmden, the only flowers blooming outdoors are winter aconite and snowdrops.

Winter aconite

(Typically, my ‘Arnold’s Promise’ witch hazel would be bursting into bloom about now but a few years ago I performed dramatic renewal pruning to reduce the size of the plant. No special technique was involved other than lopping the whole plant to ground level. Witch hazel’s stems bear flowers for many, many years, so don’t need regular pruning; it does take a few years, though before stems are old enough to begin bearing.)

Indoors, plants sense the lengthening days of brightening sunlight. African violets have been blooming for a couple of weeks and will go on doing so for weeks to come.

African violet

The same goes for the Odontoglossum pulchellum orchid, whose stems are weighed down with small waxy white, fragrant flowers.

One surprise was a butterfly bush that was in a large pot that I had brought indoors for winter. This plant enjoys bright sun and hot days, neither of which it receives indoors — it has, nonetheless, managed to cough forth, so far, a singe blue blossom. I stick my nose into the flowers, close my eyes, and inhale, and it’s midsummer.

Butterfly bush, indoors

Most dramatic are the humongous, fire engine red bloom of an amaryllis plant. It is gaudy, but appreciated anyway.

My favorites are the white blossoms now opening on Meyer lemon. The blossoms aren’t all that showy but their fragrance is heady and heavenly. No need even to get my nose up close.

I did catch one other bit of welcome color outdoors: my first sighting of bluebirds. The day is gray but the bluebird, to quote Thoreau, was “carrying the [blue] sky on its back.“

I Think My Vegetables are Nutritious

January 22, 2020/16 Comments/in Fruit, Soil, Vegetables/by Lee Reich

Nutrient Declines in Fruits and Vegetables

Growing vegetables is really quite simple. You put the seeds or transplants into sunny ground, you water and weed, and then you harvest your bounty. For that small effort, you can put on your plate food that is organically, sustainably, and (very) locally grown. Perhaps even richer in nutrients than food you can buy.
Healthy, healthful, vegetables
Studies over the past 15 or so years have documented a general decline in nutrients in our fruits and vegetables. Some people contend that our soils have been mined for their nutrients, worn out from poor farming, and therefore no longer able to provide us with nutritious food. The cure, according to these “experts,” is to sprinkle mineral-rich rock powders on the soil to replenish and rebalance that which has been lost. It all sounds very logical.

You might have sensed a big “but” looming. Here it is: But . . . further studies have pinned that nutrient decline on a dilution effect from increased yields. Pump up production with nitrogen fertilizer and water, or by breeding for increased yields, and nutrient concentrations decline; it’s as simple as that.

The final nail in the “worn out soil” coffin comes from side-by-side plantings of low- and high-yielding varieties of specific vegetables. The higher yielding varieties end up with lower concentrations of minerals and protein. The problem, then, if there is one, can be blamed on breeding and farming practices aimed at producing more bulk.

But . . .

I’m not concerned with nutrient decline in my own garden. First of all, I’ve chosen the varieties I grow — Blue Lake beans, Cherokee Purple tomatoes, Lincoln peas, Early Jersey Wakefield cabbage, Ashmead’s Kernel apple, and Fallgold raspberry, as examples — with

one thing in mind: flavor! Peas in pod It just so happens that the most flavorful fruit and vegetable varieties are ones that have been around a long time. Yields may not be heavy, but these varieties are rich in flavor. (And perhaps nutrients. Anyway,

Ashmead’s Kernel apple

if something doesn’t taste that good, I’m not going to eat much of it, so it’s irrelevant how high it is in nutrients.)

I’m also not concerned with nutrient decline because I don’t push yields to the max with repeated applications of soluble, nitrogen-rich fertilizers. My soil management is simple: One inch of compost per year spread on top of the ground of permanent vegetable beds; compost, wood chips, hay, and/or leaves around my fruit plants. As these organic materials decompose, nitrogen and other essential nutrients are bled slowly into the soil only in response to warm temperatures and moisture, the same environment that spurs plant growth.
Spreading compost
That compost is not serving up only nitrogen to my plants, or even just the big three nutrients, nitrogen, phosphorus, and potassium. Into my compost goes orange peels from Florida, avocado skins from California, and other kitchen waste, garden trimmings, some weedy hay, and, occasionally, horse manure. So the ground gets a wide variety of organic materials that, in turn, feed the compost and, in turn, feed the soil and the plants a wide spectrum of nutrients. And just to make sure that my soil lacks nothing, I occasionally sprinkle some powdered kelp around.

Herbs for Flavor, in Winter, Not Nutrition

Even if herbs were rich in nutrients, their nutritional contribution to our diets would be minimal because of the relatively small amounts actually eaten. But the small amounts needed to pizazz up a tomato sauce or frittata in winter also make herbs ideal for growing indoors in winter. A little goes a long way.

The basic problem is that many cooking herbs are Mediterranean plants that, of course, thrive best in Mediterranean conditions, with bright hot sun beating down on them. So the expectations and the reality of a windowsill herb garden often diverge. Forget about growing basil or oregano in January.

With that said, I nominate two herbs perfect for indoor growing in winter. The first is bay laurel. This plant, a small tree trained as a “standard,” has spent the last 29(!) winters near a sunny window. A freshly plucked leaf brings to soups and stews a flavor only hinted at by the dried leaf; to me, in addition to its distinctive flavor I sense an oleaginous quality hinting of olive oil.

Bay laurel

The second herb, rosemary, is my favorite for indoor growing. Rosemary tolerates being trained as a standard or fanciful topiary; it looks equally good left to its own devices to grow as a relaxed, small shrub. (Mine are trained as standards.) Pinching off a few stem tips

Small, indoor rosemary “tree”

with leaves not only puts some warm, Mediterranean sunshine into tomato sauce but also encourages growth of side shoots to keep the plant dense with shoots and leaves.

Once spring warmth has settled in around here, the bay laurel and rosemary will move outside to bask in the full force of Hudson Valley sunshine.

FOR THE GARDENER WHO HAS EVERYTHING

December 19, 2019/1 Comment/in Books, Fruit, Gardening, Tools/by Lee Reich

How Cold? How Humid?

Do you want to send a really good gift to a really good gardener? (Perhaps that gardener is you.) Problem is that most really good gardeners have pretty much everything they need except for expendables like string, seeds, or potting soil (unless they make their own. Don’t despair; I’ve come up with a few items many really good gardeners with (just about) everything they need might find useful.

At the top of my list is a nifty, little device with the odd name of Sensorpush. It’s not much bigger than an inch square pillbox, less than 3/4 inch thick, that you place wherever you want to monitor temperature and humidity — from your smartphone, via bluetooth.

Sensorpush, graph of the week’s outdoor conditions

Sensorpush, screen shot of current readings

Couple it with the WiFi Gateway and temperature and humidity can be monitored from anywhere on your smartphones. I periodically checked on my greenhouse and the outdoor temperatures here in New York when I was recently thousands of miles away in Israel.

SensorPush in greenhouse

My original use for the Sensorpush was for the greenhouse, to alert me, which it can do, if temperatures drop to a minimum that I set at 37°F. I now have another, outdoors, which alerted me to the one late frost (28°F) last spring which wiped out the crop on my peach tree. I may also put ones in my freezer and walk-in cooler.

All past information is available graphically and can be downloaded to a computer.

Water is Important

Much, much more low-tech is my new favorite watering can. It’s not any old blue watering can, it’s the French Blue Watering Can. It has everything I would look for in a watering can: hold lots of water, in this case 3 gallons; good balance when being carried and in use; and water exiting in a stream that’s gentle but not too slow. For optimum balance, get two, one for each arm.
Watering can, French blue
Although the French Blue Watering Can now beats out my previously favorite Haw’s 2 gallon, zinc plated cans, which are, admittedly, more visually elegant, Haw’s is still in the running with their beautiful, copper-enameled, 2 quart watering can that I use mostly indoors. For indoors, it’s a good volume, and the long spout can reach in among plants for more pinpoint watering once its rose is removed.
Watering can, green Haws

Books, of Course

I can’t help but mention books. Those that I mentioned last week were general categories; the really good gardener has, of course, some very specific interests and expertises. And there are books for these (I’ll stay away from my special interests to avoid having to mention, once again, any of the books that I have authored).

So, for instance, if you’re interest is in unusual vegetables, you could start with A. C. Herklots’ 1972 publication Vegetables of Southeast Asia. The book is especially rich in “greens,” including shepherd’s purse (Capsella bursa-pastoris), garland chrysanthemum (now Glebionis coronaria), and honewort (Cryptotaenia japonica). Also a slew of “Asiatic cabbages.” For something even less contemporary, there have been various printings of The Vegetable Garden by Vilmorin-Andrieux,scion of the famous French seed company. In addition to many common vegetables, of which many interesting varieties are mentioned, ferret around in the book and you’ll also find some unusuals: olluco (Ullucus tuberosus), rampion (Campanula Rapunculus), and seakale (Crambe mariitima).
Books, unusual vegetables
Eric Toensmeier’s Perennial Vegetables offers a much more contemporary take on unusual vegetables. Most of the vegetables mentioned are not really perennial in cold climates but they surely are unusual. The last I heard, very few people were growing nashua (Tropaeolum tuberosum), Chinese artichoke (Stachys offinis), chufa (Cyperus esculentus var. sativa), or winged bean (Psophocarpus tetragonobolus).

Tools and Plants

Finally, I’d like to give a shout out to the five advertisers on my blog posts (to your right). These are not just any old companies that choose to advertise. They represent businesses whose products and, in some cases, owners I know and trust (by experience) to offer the highest quality products.

Let’s start with the two nurseries. Looking for a place to buy high quality plants of pawpaw, persimmon, quince, medlar, or even more common fruits. Raintree Nursery is the one. I’ve even sent them stems from some of my more unique plants to propagate. Cummins Nursery is the go to nursery for a very wide selection of varieties of apple, pear, peach, and other familiar tree fruits on a variety of rootstocks. The rootstock helps determine such tree characters as size, adaptability to various environments as well as how soon and how much fruit you’ll pick.

(Incidentally, a nursery tree grown hundreds of miles away can be just as adapted to your site as one grown around the corner. Genetics is important, so an Ashmead’s Kernel apple grown in Washington is genetically identical to one grown in New York, or anywhere else.)

With all those new plants, some tools will be needed to help care for them. For everything from high quality soil sampling tubes to grafting supplies to hoes to tripod ladders (very stable, I own two different sizes), look to Orchard Equipment Supply Company (OESCO).

If you’re looking very specifically for cutting tools — pruning shears, pruning saws, loppers, pole saws, and the like — look no further than ARS. You can’t go wrong purchasing an ARS tool. After writing a book about pruning, I was sent many samples of pruning equipment; among the shears, ARS — specifically the VSX Series Signature Heavy Duty Pruner — is my favorite, with good weight, good steel, replaceable parts, and easy opening with just a firm squeeze of the handles. They slightly edged out my Felco and Pica shears.

Scythe Supply sells just one thing: scythes. But they offer the best of the best, as well as sharpening services and instruction. Don’t expect one of those picturesque, old scythes often turning up at garage sales, more useful for decorating a barn wall than cutting tall grass. Scythe Supply scythes are super light and well balanced with blades hammered razor sharp like those of Samurai swords. One-time Congressional candidate, homesteader, and swinger of a scythe into his nineties, Scott Nearing had this to say about scything: “It is a first-class, fresh-air exercise, that stirs the blood and flexes the muscles, while it clears the meadows.” So true. I use my mowings for compost and mulch.

FRUITS OF ISRAEL

November 20, 2019/4 Comments/in Fruit, Gardening/by Lee Reich

Olives Galore

Now I feel foolish buying olives. I recently returned from visiting Israel where there were olive trees everywhere. Irrigated plots of greenery thrived in the broad expanses of the otherwise grays and browns of the desert. Trees popped up here and there in backyards and front yards of homes in streets lined with apartment buildings as well as along cobblestone streets in rural areas. Trees were even prominent in city parks, either as self-sown wildings in less tended areas or as formal plantings.
Woman harvesting olives in Jerusalem park
And oodles of ripe or ripening olives were clinging to branches or littering the ground. Need some hand lotion? Just pluck a ripe olive, squeeze it gently, and spread out the fresh oil that drips onto your hand.

Want some olives for eating? Not so fast. Fresh-picked ripe or green olives are extremely bitter (due to oleuropein). That bitterness is removed with brine, multiple changes of water or lye solution followed by fermentation. My favorite olives are “naturally, sun-cured,” which, I imagine, means left hanging on the tree a long, long time. The dried, ripe olives I found still-clinging to branches tasted awful!
Green olive fruits
I was tempted to harvest some olives to bring home. A few other people had similar ideas, as evidenced by one woman on a ladder in a park in Jerusalem. Of course, these people were only miles or less from home; I was 5,000 plus miles from home. I let the olives be.

I actually grow olives here in the Hudson Valley, in a large container that spends summers outdoors basking in sunlight and winters in my cold basement near a large window. I should say that I grow an olive tree, rather than olives. My maximum harvest has been a half-dozen olives — which I did let hang for a long, long time, at which point they tasted delicious.
My potted olive tree My olive harest-3 fruits
Olive fruits are borne on one-year-old shoots. This year, before moving my tree to the basement, I pruned more severely than usual. That should stimulate more one-year-old shoots this spring, to, I hope, yield more fruit.

——————————————

Another of my favorite Mediterranean fruits also growing in abundance in as many guises as olive in Israel was pomegranate. Unfortunately, I just missed the harvest of this fruit. All that remained on wild plants were a few red arils still clinging to darkened portions of skins. Fruits must have been ripe somewhere because ripe fruits and fresh squeezed juice were available in markets and and street carts everywhere.
Pomegranate espalier, Israel Pomegranate display, Israel
I, of course, also grow pomegranate, similarly to olive except that, being deciduous, this plant does not need light in winter. It spends those months in a dark, walk-in cooler.

Sad to admit, my yields of pomegranate fruits have been even less than my yields of olive. As in zip, zilch, zero. The plants flower every spring and with a small brush I’ve transferred pollen from the anthers of male blossoms to the stigmas of female blossoms. (Plants each have separate male and female blossoms.) Bases of female blossoms begin to swell hopefully. Then they drop.

Every year I threaten my plant with a walk to the compost pile — to no avail.

——————————————

The third plant of the triumvirate of my favorite Mediterranean fruits is, of course, figs, which I saw in abundance in Israel mostly in wild settings. The plants lacked fruit, except for a few with small, green figlets that will either drop or ripen next spring. Fig is rather unique in its fruiting habit, able to bear fruit on one-year-old wood as well as on new, growing shoots, and the latter crop just keeps forming and ripening as long as growing conditions are to its liking.
Wild olive tree in Israel
One old tree growing in a courtyard in charming town of Sfad was hosting an old friend — or, rather, enemy — of mine, fig scale insects. I’ve battled it one my greenhouse figs.

Figs were available in the markets but I was reluctant to even try them knowing that figs must be dead ripe to taste good. At that, stage they can hardly be transported more than arm’s length from hand to mouth.
Figs for sale, Israel
Figs are one Mediterranean fruit that I grow with great success, both in my greenhouse (minimum winter temperature 37°F) and, wintering in my walk-in cooler and summering outdoors, in pots like my pomegranate. Figs are generally easy to grow because of their unique bearing habit, their lack of need for pollination, and their general tolerance for abuse.

My last day I broke down and, against my better judgement, bought some figs. Mine are better.

YOGI WAS RIGHT

October 30, 2019/9 Comments/in Fruit, Vegetables/by Lee Reich

To Do List

“It ain’t over ’til it’s over” said Yogi Berra, and so says I. Yes, the outdoor gardening season is drawing to a close around here, but I have a checklist (in my head) of things to do before finally closing the figurative and literal garden gate.

Trees, shrubs, and woody vines can be planted as long as the ground remains unfrozen. To whit, I lifted a few Belaruskaja black currant bushes from my nursery row and replanted them in the partial shade between pawpaw trees. A Wapanauka grape vine, also in the nursery row, is now where the Dutchess grape — berries too small and with ho-hum flavor — grew a couple of months ago. And today a couple of black tupelos are moving out from the nursery row to the edge of the woods, where their crimson leaves, the first to turn color, can welcome in autumn each year.

Kale, lettuce, endive, turnips, radishes, leeks, and celery still grow in the vegetable garden, but many beds are vacated for the season. Any remaining old plants will become food for the compost pile and the cleared off beds will then get a one-inch dressing of crumbly, brown compost from a pile put together last year.
Clearing bed of all weeds and plants in preparation for its layer of compost.
Freezing weather would burst the filter, pressure regulator, and timer for the drip irrigation system, so these components have been brought indoors. The rest of the system stays in place.

The drip system may now be out of commission but some watering may be needed. Occasional days with bright sunlight and warm mean hand watering. How primitive!

Planning Ahead, Soil-wise

Making compost for use next year, same time, same place, is also on my checklist. Especially today, so the compost creatures within the pile can take advantage of lingering warmth in the air to work overtime. A pile that gets hot cooks to death most weed seeds and pests that hitchhike into the pile on what I throw in. And I throw in everything, in spite of admonitions from “experts” to keep diseased or insect-ridden leaves, stems, or fruits out of compost piles.

So today, after loading horse manure, with wood shavings bedding, into my truck pitchforkful by pitchforkful, I drove home and unloaded everything pitchforkful by pitchforkful into my compost bins. Each bin got a lot more than a restricted diet of just the horse manure mix, though. I alternated layers of manure with mowings scythed from my small hayfield, wetting down each layer well and sprinkling occasional layers with soil, for bulk, and ground limestone, to counteract soil acidity.
Compost bins
Manure is not a necessity for good compost. The manure mostly is for nitrogen, one of the two main foods of compost microorganisms. Some of my piles get that nitrogen from soybean meal, an animal feed usually meant for creatures that you don’t need a microscope to see. Early in the season, young grasses and weeds, which are high in nitrogen, do the same. And truth be told, any pile of plant material, if left long enough, will turn to compost. The nitrogen helps the material chug along faster on its way to compost, and the faster the microbes work, the hotter it gets.

Winter Work for Microbes

I’ll be feeding my last compost pile of the season all winter long. Just a little at a time, mostly scraps and vegetable trimmings from the kitchen with occasional toppings of leftover hay. Adding stuff slowly to a compost pile doesn’t let enough critical mass build up for heat, and especially not in winter’s cold.
Dog and chickens on compost pile
No matter. I just let piles that don’t heat up sit longer before I use them. It’s the combination of time and temperature that does in all the bad guys that hitchhike into my compost piles. So 1 hour at 140° F. might have the same deadly effect as a week at 115° F. My hot piles sit for a year before I use them; the cold piles cook longer. It ain’t over ‘til it’s over.

TASTING AND TIDYING, OR NOT

Fruit Heaven

Hudson’s Golden Gem apple

I remember a few years ago of having a most fruitful — and I mean this very literally — experience visiting one of the USDA’s germplasm repositories. “Germplasm repository” doesn’t sound like the kind of place anyone would want to be, but these USDA repositories are, in fact, sunny, colorful places, often redolent with enticing aromas. In the case of the one I visited, the aroma was of ripening apples.

Germplasm is the stuff that gives rise to an organism, and the USDA has set up repositories around the country to house various kinds of plants. Each repository is situated where a particular group of plants grows well. So Davis, California is home to the repository for figs, pomegranates, and Asian persimmons; Corvallis, Oregon is the repository for pears, gooseberries, and mint; and Geneva, New York, where I visited, houses the collections of apples and American-type grapes. (My own gooseberry collection helped build the gooseberry collection at Corvallis about 30 years ago.)

Taking into account seed collections and other, related work, these repositories maintain over 20,000 accessions of plants representing over 300 species. Germplasm from these collections is available to scientist and other interested citizens, which is how I obtained grafting wood to make most of the rare varieties of apples and pears that I grow.

So there I was — a fruitophile — standing with clipboard in hand and camera in pocket in in a field of apple trees, each one a different variety. My mission: Photograph and collect 3 to 4 samples of a couple of dozen varieties. What sweet labor! (I had previously contacted the repository staff and received permission).

Up and down the rows I went, photographing, collecting, and, of course, tasting. Apples have been cultivated for so long and are so popular a fruit that it’s no wonder that such great variation exists in the fruits’ appearances and flavors. Flavors include anise-flavored Ellison’s Orange, sweet Mollie’s Delicious, spicy-tart Cox’s Orange Pippin, and everything in between and beyond. The range in color goes from gray-brown Pomme Grise to cheery red-splashed yellow King of the Pippin. And then there are variations in fruit size and shape and, less obvious, characteristics such as pest resistance, productivity, and cold tolerance.

Ashmead’s Kernel apple

Most important, to me, is flavor. I should have brought a palate cleanser because after a while all the varieties were beginning to taste like . . . well . . . apples. Nonetheless, two varieties that I did not grow did stand out for flavor; I ordered grafting wood of Hudson’s Golden Gem and Pitmaston Pineapple to graft onto trunks of my Ingrid Marie trees once I lop their tops off.

After the apples, there were grapes to photograph and sample.

Tidy Not

Boy, would I love to tidy things up with some pruning now. The Golden Celebration rose bush would look nicer in coming months with those couple of tall, gawky stems cut off or back.

Grape and hardy kiwi stems are reaching out all over the place, grabbing onto each other and anything else they can wrap around.
Kiwi vines
The pear trees have a nice spreading form — except for watersprouts shooting vigorously skyward from the uppersides of some of the spreading branches. How nice it would be to cut these plants back now rather than in spring.

But I’m going to restrain myself from doing any pruning. As stated in The Pruning Book (by me!), “Although immediate regrowth rarely occurs after late summer or autumn pruning, cells right at the cut are stirred into activity to close off the wound. Active cells are liable to be injured by cold weather, which is a reason to avoid pruning in late summer or autumn except in climates with mild winters or with plants that are very hardy to cold.”

Gooseberries and currants are super cold hardy plants and begin growth relatively early in spring. All of which makes a good case for pruning those plants now.

And a Case for Not Tidying

Rather than prune, a good place to re-channel that “tidy everything up” urge is in the vegetable and flower garden.

Cleaning up is one way to lessen pest problems next year. As I pulled out spent bush bean plants, I gingerly placed them into the garden cart and, from there, onto the compost pile, trying not to disturb the resident bean beetles. Those bean beetles had hoped to spend the winter on site, to emerge next spring and lay eggs on next year’s bean plants. I’m hoping to “cook” as many of them as possible in the compost pile.

Tomato plants are looking a bit ragged even though they’re still bearing some tomatoes for fresh eating. Gathering up all stems, leaves, and old fruits and composting them reduces the inoculum load of diseases such as early blight and septoria leaf spot. Left in place, they would spend winter out in the garden ready to infect next year’s plants. It’s not a question of eradication, which isn’t possible, but of balance.
Tidy vegetable garden beds
Cutting down old peony stems and composting them takes inoculum for next years botrytis disease off-site. Left to infect plants next spring, botrytis could keep peony flower buds from unraveling.

As Charles Dudley Warner wrote over a hundred years ago (in My Summer in the Garden, which I highly recommend and is much more than a gardening book), “the closing scenes are not necessarily funereal . . . a garden . . . goes into winter-quarters . . . neat and trim . . . so that its last days shall not present a scene of melancholy ruin and decay.”

Battle for Figs: Victory

October 15, 2019/32 Comments/in Fruit, Pests/by Lee Reich

Some History

I don’t know the score over the years, but this year’s victory is mine. The battles have been with scale insects, both armored scales and their cousins, mealybugs (but rarely both in the same year), on my greenhouse fig plants.
Eating a fig
Those fig plants are planted in the ground in a minimally heated greenhouse, where winter temperatures can sink to about 35°F. The oldest of these plants have trunks 8 inches in diameter. They thrived for years without any pest problems, scale of otherwise. A few years ago, the insects made their appearance, sometimes ruining almost the whole crop.
Mealybug
Over the years I fought them in various ways. One year it was spraying the dormant plants with alcohol. Another year it was, more aggressively, scrubbing trunks and stems of dormant plants with a toothbrush dipped in alcohol. Ants herd and protect scale insects, so another year I fenced the ants off the plants with a band of masking tape coated with forever (almost) sticky Tangletrap around the trunk of each plant.

An expensive but short-lived success was the two releases of the predatory ladybird beetle Cryptolaemus montrouzieri and the parasitoid wasp Anagyrus pseudococci.

Mealybug destroyer

These biocontrol helpers ended up valuing each fig at about a dollar, still worth it. I screened all openings in the greenhouse, hoping to perennialize them inside. (It was not effective.)

Battle Plan, Done

So this year I tried a multipronged approach.

The biggest change was, rather than growing the figs as bushy trees, training them as espaliers. Espalier is the training of plants to an orderly, usually two-dimensional form both for beauty and, in the case of fruit plants, for good production of high quality fruit. For my figs, an additional benefit would be that each plant would only have one point of contact — its trunk — with the ground. IA band of masking tape coated with Tangletrap would be a roadblock on the ant highway. (Plus the look of the plants always elicits a “Wow” from visitors.)
Rabbi Samuel fig, espaliered in greenhouse
The fig plant growing near the greenhouse endwall has a short trunk that, after rising to about 18 inches from ground level, bifurcates into two, self-supporting horizontal arms extending parallel to the wall in opposite directions. At the head of each of the south beds, a fig tree is planted each of whose trunk is terminated by just a single, self-supporting, horizontal arm reaching down the bed to the sidewall. With just a trunk and one or two arms, thoroughly scrubbing down the dormant plant with alcohol is a relatively quick job. Quick enough to prevent 2 or 3 scrubbing before plants resume growth in early spring from becoming tedious.

Another nice feature of this training system is that pruning the plants at the end of the season is a no-brainer. Vertical shoots that rise up from the horizontal arms are thinned to keep neighboring shoots 8 inches apart and helped along in their vertical growth by being trained to pieces of bamboo attached to the greenhouse roof. (Yes, an ant could walk up the wall and across the roof of the greenhouse and then down the bamboo to get at the plants but they are either not that smart or energetic; it hasn’t happened.)

A little later in the early part of the greenhouse growing season I gave the plants some dowsings with neem oil. I’m not sure how effective the neem component is but “horticultural oil” itself is effective in fighting off scale insects.

A ring of cinnamon around the base of each plant provided further disincentive to the ants, who will not cross a cinnamon line. The cinnamon and the Tangletrap did need renewal once per season.

As new fig shoots soared skyward near the greenhouse roof, I used a pole pruner to prune out the top of the growing shoot. Side branches, of course, then grew, and I periodically had to to hack them back also.

Uh Oh, But All Still Good

Everything was copacetic and we were harvesting figs, which formed along the vertical stems at the juncture of almost every leaf. Then, in late August I noticed some mealybugs on one plant. Time for Cryptolaemus montrouzieri again. I released them in early September and we were back in business, harvesting large handfuls of three different varieties of delciously sweet figs — San Piero, Brown Turkey, and Rabbi Samuel — daily.

And then, just today, I noticed armored scales on the plants, and a few ants! I’m not sure how the ants are getting onto the plants, but one possible “benefit” of the armored scales is hardly any mealybugs. Perhaps they can’t coexist.
Fig scale
All the measures I took against mealybugs should also be effective against the armored scales, except for the Cryptolaemus montrouzieri. Their predator Aphytis melinus, also known as the Golden Chalcid, has been effective against armored scales.

I’m not taking action. With less sunlight and cooler temperatures the figs trees have slowed down, running out of new stems on which to hang fruit. No matter; it’s been a good season of fresh figs.

TWENTY-TWENTY FORESIGHT

September 19, 2019/8 Comments/in Flowers, Fruit, Gardening, Planning/by Lee Reich

North Vegetable Garden

I’m stepping outside this sunny afternoon for a walk around the farmden, pad and pen in hand to evaluate some of this season’s goings on to make notes for next season. Not that the season is anywhere near over yet. I expect to be out and about with pitchfork, harvest basket, and garden cart at least into December. But no surprises are expected at this point.

Starting in the north vegetable garden: tomatoes. Over the years I’ve honed the number of varieties here from too many to our half-dozen or so favorites.

Valencia tomato

The goal is top-notch flavor and reasonable productivity. San Marzano, which is very productive, might taste like cotton fresh but it’s a must for the best-tasting cooked tomatoes. The San Marzanos get their dedicated canning jars, but also good canned is Blue Beech and, great for fresh eating also, are Amish Paste and Anna Russian.

Three more, mostly for fresh eating next year, are Paul Robeson, Belgian Giant, and Valencia. Valencia has year after year proven to be a very good, very beautiful, and productive tomato. Pretty also, round, smooth, and pale orange. Cherokee Purple hardly produced this year, and hasn’t in years past, so it’s scrapped from the list for next year.

I consider Sungold to be the best-tasting cherry tomato, and it’s still bearing a daily abundance of persimmon-orange fruits. I put in 8 plants; next year, I’ll plant a few more.

That makes a total of only seven tomato varieties — unless someone twists my arm into trying any other variety.

I’ll try for a repeat abundance of peppers next year by again growing Carmen and Sweet Italia.

Sweet Italia peppers

Sweet Italia tastes better but Carmen bears a little better, especially now. The non-hot hot pepper Habenada, is billed as having hot pepper flavor minus the hotness. More like no hotness and no flavor, a no-go for next year.

South Vegetable Garden

Walking over to the “south garden,” the highlights this year were cauliflower, beans, and squash. Cauliflower is allegedly a challenge to grow. I don’t like it so grew it just for the challenge, and because Deb likes it. I was successful, and she can eat it all.

Blue Lake and Kentucky Wonder pole beans keep pumping tender new beans, as pole beans are wont to do. Or is it Blue Lake and Romano? Or Kentucky Wonder and Romano? The row label is buried deep in a wall of foliage so I won’t know until the end of the season. I guess two plants per pole, with poles about a foot apart, is too crowded. Next year: one plant per pole.

Pole beans begin bearing late so I also grow bush beans (bush Blue Lake and bush Romano), which peter out after a couple of weeks but yield an early crop for the freezer. I usually put in a second planting also, which is — note for next year — not needed. We didn’t have to harvest any of them because the pole beans kicked in soon enough.

It’s been a banner year for winter squash. I usually plant squash out in the meadow in the cleared strip of land between the dwarf apple trees. And usually, deer or my poultry eat the vines or the fruit so the harvest is usually nil. This year I planted squash in the rich soil along and inside the back fence of the south garden, which backs up to the poultry run. The squash climbed up and over the fence and onto the fenced roof of the run; now there’s plenty to harvest, perhaps too many! Winter squash on poultry run

South Vegetable Garden

Two flowers were standouts this year: On a whim I purchased red buckwheat seed from Baker’s Creek (www.rareseeds.com). With no place special in mind about where to plant it, I ended up sprinkling the seed in a bed just outside the north vegetable garden.

For the past couple of months it’s been a 4-foot high cloud of pale red beauty, which, along with how easy it is to grow, earns it a place in next year’s garden. But where?

One other flower stood out also, delphinium. Not a five foot spire of pale blue — I also have them, the Pacific Giant hybrids — but a spire less than two feet tall with dark blue flowers.
Delphinium, Blue Mirror
It’s Blue Mirror Chinese delphinium (www.reneesgarden.com) and it surprised me by blooming its first year from seed. Let’s see how perennial this perennial turns out to be. Around here, its giant cousins typically die out after a couple of years.

All in all, it’s been an excellent growing season. Spring frost hazard was minor for tree fruits. Rainfall and sunshine were balanced well. Pest problems were minor. Pears are still challenging to harvest at just the right moment so that they can ripen indoors to that delectable window between underripe grassy and overripe sleepy. I did get Concorde at the right moment this year. The ripe fruits are delectable, combining some of the smooth buttery sweetness of Magness pear along with a dash of vanilla.
