Future Tense, Present Tense

July 25, 2018/14 Comments/in Fruit, Planning, Pruning/by Lee Reich

Past is Present . . . No! . . . Present is Future

Gardening is so much about planning for the future. Dropping seemingly dead, brown specks into a seed flat in spring in anticipation of juicy, red tomatoes in summer is fun and exciting.

But now, in the glory of summer, I don’t particularly like planning, which means thinking forward to the crisp days of autumn that lie ahead. But I must. I know that when that time finally comes, I’ll have had my fill of hot weather. And the cooler weather coupled with shorter days and low-hanging sun will have tomatoes, cucumbers, peppers, and other summer vegetables on the wane. Planning and action now let me have a whole other garden come autumn, a garden notable for its shades of green (from leaves) rather than the reds and yellows (from fruits) of summer’s garden.

I’ll need plants and free space ready for my autumn garden. Some plants are already in place: One bed has been home, since early spring, to kale, which keeps growing as we harvest leaves through spring and summer, and brussels sprouts, from which harvest won’t even begin until early October.

Cabbage plants sown in seed flats in early June are about ready to plant now out in the garden for autumn harvest. Today I sprinkled seeds of endive into mini-furrows in potting soil in a seed flat. The endive seedlings will be ready to move out into the garden in 5 or 6 weeks. I’ve also sown more kale seeds to supplement the spring kale for harvest into and perhaps through (depending on the weather) winter.

Early August will be a good time, around here, for planting Watermelon — the Watermelon variety of winter radish, whose innards look like cut watermelon but taste very radish-y. Also turnips, the delicious variety Hakurei.

I’m also sowing lettuce seeds, which I’ve been doing since spring and continue to do every few weeks. They also go into seed flats, ‘GrowEase’ seed starters, from which I can pop out transplants into any spaces that open up here and there around the garden.

Looking for an Opening

So where am I going to plant all those endives, cabbages, winter radishes, and turnips? The autumn garden will also need room for direct sowings of quickly maturing autumn vegetables like arugula, mustard, and lesser known salad “greens” like mâche (corn salad), erba stella (minutina), and claytonia (miner’s lettuce). The garden is packed full of plants now.

Endive, radish, radicchio in fall

Going into August, space will open up for those autumn garden plants. From my first planting in mid-May, I’ll pick the last ripe ear of Golden Bantam sweet corn around mid-August, then have a whole bed available as soon as I clear away the spent stalks. Similarly for the beds of onions, early bush beans, and edamame.

Black Raspberries (Blackcaps) Redux

Enough planning for autumn and beyond. I’m going outside to feast on blueberries, black raspberries, and gooseberries, for me the essence of summer. Black raspberry

Now that I think of it, as soon as the black raspberries finish up, which is very soon, I do have to plan for them also, for late summer and autumn. The varieties I grow — Niwot and Ohio’s Treasure — are unique in being two-crop black raspberries, just like my “fall-bearing” (“everbearing”) raspberries. That is, they bear in early summer on stems that grew last year, just like conventional black raspberries. But — and here is where they are unique — they also bear in late summer and autumn beginning at the tips of new stems that rose from ground level this spring.

Last year’s stems are just finishing fruiting, after which they begin to die. I’ll cut them away to make room for the new stems and to keep the late summer and autumn harvest from these new stems from becoming a thorny nightmare. Black raspberry fruit

Berries Begin

Green Thumb Not Necessary

Every day, for some time now, my strawberry bed has yielded about five cups, or almost 2 pounds of strawberries daily. And that from a bed only ten feet long and three feet wide, with a double row of plants set a foot apart in the row. Strawberry harvest
Good yield from a strawberry bed has nothing to do with green thumbs. I just did what’s required to keep the plants happy and healthy. To whit . . .

I planted the bed last spring to replace my five-year-old bed. About five years is about how long it takes for a strawberry bed to peter out due to inroads of weeds and diseases, including some viruses whose symptoms are not all that evident.

To keep my new plants removed from any problems lurking in the old soil, I located the new bed in a different place from the old one. Further forestalling problems, plants came not from a generous neighbor and not from my old bed, but from a nursery selling “certified disease-free” plants.

I chose to grow them in a “spaced plant” system (which does not involve getting plants high, ha, ha) but allows each plant a square foot of space. Throughout the growing season, I clipped off any runners and daughter plants attempting to establish themselves and crowd into the mother plant’s space.

Other growing systems allow for runners, which makes for more economical planting of a bed but reduced initial yield. Given free rein, though, new plants eventually become the worst weed in any strawberry bed; they must be dealt with in some way.

Did I mention that the new bed, like the old one, was in the vegetable garden, where the soil is rich in nutrients and organic matter, with plants’ thirst quenched daily via drip irrigation?

In late December, when the ground had frozen about an inch deep, plants were snuggled beneath mulch as protection from winter cold. Straw, pine needles, wood shavings — any loose organic material will do.

Come spring, just as soon as plants began to awaken, I pulled back new growth beneath the mulch and tucked it under the plants’ leaves. I also trimmed off any dead leaves. The new job for the mulch was then to keep the soil moist and the soon-to-form ripening berries clean of soil.

That’s it, for all those berries, fresh picked every morning. Every morning for a little while longer, that is. I planted a “junebearing” variety of strawberry, Earliglow, known for earliness and good flavor, but bearing only for a few weeks in June. Other varieties, so called “everbearing” and ”day neutral” varieties, bear repeatedly through the season.
Netted strawberries Once Earliglow stops bearing for the season, the bed will need renovation and, through the season, its runners pinched off weekly to keep each plant “spacey.”

Better Berries

You might wonder: Why such a relatively small planting of strawberries, and why only junebearers? This admission may be sacrilege: I’m not a big fan of strawberries. I like the fruit well enough, but mostly because they are the first fresh fruit of the season.

(One other fruit does beat out strawberries as the first fruit of the season. They are honey berries, a kind of edible honeysuckle. Their flavor, thus far, has not impressed me. Breeding and cultivating honeyberries is in its infancy. They’re perhaps where apple was 2000 years ago, and the future might bring more flavorful ones.)

Back to strawberries . . . another of their deficiencies, in my view, is that you have to crawl for the fruit. And, as mentioned previously, although technically perennial, beds should replanted in a new location every 5 years or so.

The Best Berries

The fresh strawberries came on the scene on the tails of last year’s frozen blueberries, one of my favorite fruits. Perfect. (The loss of frozen blueberries is softened by the freshness of the strawberries.)

Last frozen blueberries, fresh picked strawberries

And just as the fresh strawberries fade out for the season, fresh blueberries will begin yielding this season’s bounty. Also, at the same time, black currants and red currants. And then black raspberries, and then . . . and on and on.

All You Need To Know About Blueberries

Interested in growing your own blueberries? It’s easy, if you meet their basic needs, all of which, including varieties, harvest, and other pressing questions about growing blueberries, will be covered at my upcoming BLUEBERRY GROWING WORKSHOP. The workshop will take place on my New Paltz farmden on July 22, 2018 from 9:30-11:30am, at a cost of $48. Registration is a must.

Bedding Down

May 24, 2018/6 Comments/in Design, Planning, Vegetables/by Lee Reich

Flat Beds

My vegetable garden is in beds. Your vegetable garden is in beds. Seems like just about everybody plants in beds these days. And with good reason. Beds make more efficient use of garden space. Soil compaction is avoided because planting, weeding, pruning, and harvesting can be done with feet in the paths. And the shapes of the beds can help make even a vegetable garden look prettier, especially with decorative plants edging the beds.

Raised beds are also one way to grow happy plants in otherwise poorly drained ground, or in ground that has been contaminated by lead or arsenic. Such contamination is likely to occur from past use of leaded gasoline near roadways, from old paint near buildings, and from residual pesticides in sites that were once orchards.

My vegetable garden is laid out in 3-foot-wide beds with 18-inch-wide paths between them that feed into one 5-foot-wide path down the center of the garden. Many gardeners, when considering planting in beds, equate that with RAISED beds. My vegetable beds are not intended to be raised even a hair above the paths. My garden's beds

When I began my garden, I laid out the beds and covered them with compost, and then laid wood chips from local arborists in the paths. The difference in appearance of the two materials makes it easy to see where to walk and where not to walk. (For most people, that is. A well-known food writer once visited my garden. As I walked up a path, he tromped along next to me — right up the middle of the bed adjacent to the path! — until I let out a scream that brought him to an abrupt stop. Some lush plants in the bed were admittedly flopping onto the path, obscuring the difference between walking and planting areas.)

Raised Beds

Soil in raised beds is usually held there with boards or other edging. That edging material might itself be decorative: lumber, bricks, roof tiles, or, in a “colonial” garden, logs. Garden beds

Ideally, any wooden edging is rot resistant. Locust or redwood would be my top choices, but hard to get. “Manufactured” lumber, such as Trex, is another possibility. Then again, pine or spruce boards are readily available, relatively inexpensive, and should last quite a few years.

A six-inch-high bed provides enough well-drained root depth for pretty much all vegetable plants.

One disadvantage to raised beds is that you have get soil to fill them up. That soil could, of course, come from what will be the paths. Metal edged raised beds If the area is wet, though, taking soil from paths is going to lower them, making them that much wetter.

Most people bring in soil for raised beds, and, in the interest of having the best possible garden, make that “soil” compost. Not a good idea. For one thing, compost is mostly “organic matter,” meaning compounds of carbon, hydrogen, and oxygen. With time, as organic matter decomposes to nourish soil microorganisms and plants, it disappears, literally, becoming carbon dioxide and water. So a raised bed filled with compost will eventually shrink down to almost nothing.

The thing to do is to fill beds almost to their brims with any any well-drained soil. Fertility is not important; that will come from the one to two inches of compost with which the soil is topped. Replenishing the compost each year will provide all the nutrition plants need for that year; no additional fertilizer is necessary. And no need to dig or rototill the compost into the ground.

One more thing about raised beds: The improved drainage also means that they dry out faster, so benefit from irrigation.

Table-like Beds, Not

If you were to walk into my garden, you might notice that my planting beds are indeed a bit higher than the paths. This was not deliberate.

Each year for many years I’ve topped all my beds and an inch or two of compost. Dog Sammy and garden beds Paths get replenished with wood chips only if they start to get weedy or bare soil starts peeking through.

If it weren’t for decomposition, those yearly additions of compost would have made each bed into a “table” more than three feet high. It hasn’t. Q.E.D.

(Micro)climate Change

May 3, 2018/3 Comments/in Fruit, Gardening, Planning/by Lee Reich

As the train rolled southbound along the east bank of the Hudson River, I took in the varied landscapes along the opposite west bank. Spilling down the slope to the river on that bank at one point was what appeared, from a distance, to be a vineyard. I was envious.

(I never could understand why the region here is called the Hudson Valley. Along much of the Hudson, the land rises steeply right up from river’s edge. Where’s the valley?)

I wasn’t envious of the riverfront site of the vineyard property. I wasn’t even envious of having a whole vineyard of grapes. (I cultivate about a dozen vines.)

What I did envy was the microclimate of the site. Microclimates are pockets of air and soil that are colder, warmer, more or less windy, even more or less humid than the general climate, due to such influences as slopes, walls, and pavement.

The vineyard was not that far from my home, but the microclimate was worlds apart. Every parcel of land, from a forty-acre farm field to a quarter acre lot, will have some microclimates, and siting plants with this in mind can spell the difference between whether or not they thrive or even survive. Microclimate, early tulips I’m banking, for instance, on the slightly warmer temperatures near the wall of my house to get my stewartia tree, which is borderline hardy here, through our winters. (It has.) And I expect spring to arrive early each year, with a colorful blaze of tulips, in the bed pressed up against the south side of my house. Proximity to paving also warms things up a bit.

Microclimate for cold, microclimate for warmth

Microclimate isn’t always about trying to keep a plant warmer in winter, or speeding up growth in spring. It’s also useful for keeping plants cooler. By training my hardy kiwifruit (Actinidia spp.) vines right up against the shaded, north sides of their hefty supports, I keep the sun off their trunks in winter and avoid the splitting that occurs when trunks are warmed during winter days, then precipitously cooled as the winter sun drops below the horizon. Microclimate, lingering snow By planting the coveted blue poppy in a bed on the east side of my house, I hoped to give the plant the summer coolness that it demands. (That east bed was still too sultry; the plants collapsed, dead.)

Microclimates are important when growing fruit plants that blossom early in the season because frozen blossoms do not go on to become fruits. Early season bloomers need microclimates that are slow to warm up.

South facing slopes stare full face at the sun, so these slopes warm up early in spring and are warmer in both summer and winter. Therefore, a south facing slope—even if the grade is only slight—can be used to hasten fruit ripening on a plant like persimmon, which blooms late but needs a long season when grown near its northern limits.

Right after I push soil over the first seeds of sweet corn that I plant, I firm it over that hole with my foot at an angle to make a south-facing depression in the ground. That mini-slope will warm up just a wee bit sooner than flat ground.

The sun glances off north slopes, delaying their warming in spring and keeping them cooler in summer. Such a microclimate is ideal for an early blooming fruit tree like apricot or peach, and for plants, such as sweet peas, that enjoy cool summer weather. Likewise ideal for such plants is near the north side of a building, where shade remains through winter and the early part of the growing season.

If a slope actually has some elevation to it, the air is going to cool by one degree Fahrenheit every three-hundred feet going up the slope. If I had sloping ground, which I don’t, and sought a cooler location for planting, I’d avoid planting at the very top of the slope, though, because the upper reaches are usually windy.

A cold spot, here

Ideal vineyard site, from plant perspective, in Germany

Counterintuitively, the very bottom of a slope will also be a cooler microclimate. On nights when the sky is clear, with no clouds or leafy trees to block re-radiation of the sun’s heat from the ground back to the heavens, the air at ground level cools. An “inversion” occurs, with warmer air higher up. The cold air, which is denser than warm air, flows downhill to settle into depressions, just as a liquid flows downhill. A low point would be the worst possible location for planting strawberries, which grow near ground level and whose early blossoms are threatened by late frosts in spring. Any dense fence or shrubbery on a slope stops the downward flow of cold air, which will pool, just as dammed water would, near the upper side of the barrier.

Among the fruits I grow are apples, peaches, plums, and pears, all of which tend to bloom early. My site, unfortunately, is just about the worst possible site for growing these fruits. Apple blossoms The cold air that settles here on clear spring nights increases the likelihood of late frosts and also causes moisture to condense on the plants, leaving them more susceptible to disease. Hence my envy for that sloping vineyard site.

Warm, Spring Weather is Coming

March 21, 2018/0 Comments/in Flowers, Gardening, Planning/by Lee Reich

Poppies in Snow

Snow today (March 7) — a perfect time to plant seeds outdoors. Yes, really!
Obviously, not just any seed can be sown in snow. The ground is still frozen solid so I can’t easily cover seeds with soil. And cold temperatures are going to rot most seeds before the weather warms enough for them to germinate and grow.

I’m planting poppy seeds. It does seem harsh to sow a flower whose seeds are hardly finer than dust and whose petals are as delicate as fairy shawls. But early sowing is a must, because poppy seedlings thrive during the cool, moist weather of early spring. Covering the seeds with soil? No problem: Poppy seeds sprout best left uncovered. And because poppies don’t transplant well, their seeds are best sown right where the flowers are going to grow.

I’ll be sowing annual poppies, whose petals and leaves are more delicate than those of Oriental poppies. Corn poppy (Papaver rhoeas) once dotted the grain fields of Europe with its blood red flowers.

Corn poppy

Corn poppies and pear trees

These flowers were immortalized in the poem Flander’s Fields, symbolizing lives lost in World War I. On Memorial and Veteran’s Day, red tissue-paper “corn poppies” are still distributed in memory of wars’ victims. Shirley poppy is a kind of corn poppy that has white lines along the edges of its petals. Corn and Shirley poppies begin blooming shortly after spring-flowering bulbs have finished their show, and continue blooming through July.

California poppy (Eschscholtzis californica) was named in honor of Dr. Eschscholtz, a Russian ship surgeon who found these bright orange flowers blanketing California hillsides. California poppy is a perennial but in our harsh winters must me treated like an annual and sown yearly.

Each winter, it doesn’t seem possible that the dust-like seeds I sprinkle atop the ground’s chilly, white blanket could ever amount to anything. Each spring, I’m amazed to see myriad of ferny poppy leaves, then flowers.

Warmer Spring in Greenhouse

The sun is getting brighter in the sky day by day so it’s mostly lack of heat that’s holding back plant growth. Outdoors, there’s not much to do about a lack of heat. In the greenhouse, it’s time to turn up the thermostat a bit.

Thus far, I’ve let greenhouse temperatures drop no lower than about 38 degrees F. During bright, sunny days, of course, temperatures push up into the 80s. Seedlings in greenhouse An exhaust fan keeps temperatures from getting too high, which, with lows in the 30s, would wreak havoc with plant growth, at the very least causing lettuce, mustard, and arugula to go to seed and lose quality too soon.

Adding just a few degrees at the bottom end of the temperature scale will spur growth in the newly sprouting lettuce, arugula, onion, and leek seedlings. This new minimum temperature of 43 degrees Fahrenheit strikes a congenial balance between plant growth and the cost and conservation of energy, propane in this case.

Bottom Heat for Seedlings

I’m not skimping on heat when it comes to germinating seeds. Seeds require more heat to sprout than seedlings need to grow. Too little heat and seeds either rot or sprout too slowly. Heating mat
Fortunately, seeds need little or, in some cases, no light to sprout. Some people use the warmth atop their refrigerator for seed germination; the top of my refrigerator isn’t warm at all. Some people germinate their seeds at a warm spot in their house, such as near a heating duct; my home, heated mostly with wood, has no such oases. The temperatures near the wood stove swing over too wide a temperature range for good germination.

Years ago I invested in a thermostatically controlled heating mat, made especially for gardening. The mat is in the greenhouse, so even if greenhouse temperatures drop to 43 degrees F., my seed flats sit with their bottoms soaking up 75 degree warmth from the mat below.

That’s how much warmth is needed to get the pepper and eggplant seeds I sowed this week to sprout.

This Bud’s for You

March 14, 2018/2 Comments/in Flowers, Fruit, Planning, Pruning/by Lee Reich

Swelling Buds

What an exciting time of year! After a spate of 50 plus degree temperatures, lawn grass — bare now although it could be buried a foot deep in snow by the time you read this — has turned a slightly more vibrant shade of green. Like a developing photographic film (remember film?), the balsam fir, arborvitae, and hemlock trees I’m looking at outside my window, have also greened up a bit more.

Going outside to peer more closely at trees and shrubs reveals the slightest swelling of their buds. Earlier in winter, no amount of warmth could have caused this. As a cold weather survival mechanism, hardy trees and shrubs are “smart” enough to know to stay dormant until warm weather signals that it’s safe for tender young sprouts and flowers to emerge.

These plants stay asleep until they’ve experienced a certain number of hours of cool temperatures, the amount varying with both the kind and variety of plant.

Once that cold “bank” has been filled, the plants merely respond to warming temperatures. Which, for many plants, is now.

Physiology aside, the buds provide an interesting winter diversion; look at their sizes, their shapes, their colors, and textures. (Admittedly, their interest would pale in the landscape exploding into flowers and leaves, when the buds anyway mostly disappear into flowers or leaves until later in summer when new ones re-form.)

More than just interest, buds are useful. Buds can be used to identify the kind of plant as well as whether flower buds are in the offing. Or perhaps that flower buds were in the offing but were damaged by winter cold.

Info from Buds

The first bit of information I glean from winter buds is plant identification. To begin, how are the buds arranged along the stem? Buds directly opposite each other, which is relatively rare for local trees, narrows the choice down to maple, ash, dogwood, and horse chestnut, or, as some people remember it, MAD Horse.

L to R: peach, pawpaw, fantail willow, viburnum, dogwood

Of course, once I identify a tree as, for example, a maple, I have to look for other details, such as the bark, to tell if it is a red, sugar, silver, or Norway maple.

(A few less common trees also have opposite leaves, including katsura and paulownia, both non-native, and viburnums, some of which are native. Most shrubs have opposite leaves.)

Buds that are not opposite each other along a stem might be alternating along the stem, they might be whorled, or they might be almost, but not quite opposite, presenting a much wider field of plants from which to choose.

Then it’s time for a closer look at the buds themselves. Some plants—viburnums, for example—have naked buds, enveloped only by the first pair of (small) leaves, rather than the scaly covering protecting the buds of most other plants. Buds of plants such as maples have buds enclosed in scales that overlap like roof shingles. Or two or three scales might enclose a bud without any overlap, as they do on tuliptree.

Mature plants have two kinds of buds. Those that are longer and thinner will expand into shoots. Flower buds are usually fatter and rounder. I note how dogwood flower buds stand proud of the stems like buttons atop stalks — very decorative if you take the time to have a look. I take a look at a peach branch with its compound bud: a single, slim stem bud in escort between two fat flower buds.

Peach buds

Apple and crabapple flower buds occur mostly at the ends of stubby stems, called spurs, that elongate only a half an inch or so yearly. Pawpaws fruit buds are fat and round with a brown, velour, covering.

Practicalities aside, buds can predict what kind of flower show or fruit crop to expect, barring interference from late frosts, insects, diseases, birds, or squirrels. If peach fruit buds just sit in place rather than fattening as winter draws to a close, I’ll know that the night back in January when temperatures plummeted to minus 18 degrees Fahrenheit did them in, or at least some of them.

More Winter Details

Back to winter plant identification and entertainment. Looking more carefully at these leafless plants promotes familiarity. Notice the intricacies of their various barks; shagboark hickory, sugar maple, persimmon, white birch, and, my favorite, hackberry,

Hackberry bark

are very characteristic. Note twigs’ color, presence of ridges or lenticels (corky pores), even their taste or aroma. The aromas of yellow birch (wintergreen aroma), sassafras, and black cherry (almond) practically shout out their identification.

End of Year Punch List

December 20, 2017/6 Comments/in Fruit, Pests, Planning, Tools/by Lee Reich

Winterizing

My carpenter friends, near the end of their projects, have their “punch lists” to serve as reminders what odds and ends still need to be done. I similarly have a punch list for my gardens, a punch list that marks the end of the growing season, a list of what (I hope) will get done before I drop the first seeds in the ground next spring.

(No need for an entry on the punch list to have the ground ready for that seed. Beds have been mulched with compost and are ready for planting.)

Hardy, potted plants, including some roses, pear trees, and Nanking cherries, can’t have their roots exposed to the full brunt of winter cold. plants, almost ready for winter I’ve huddled all these pots together against the north wall of my house but soon have to mound leaves or wood chips up to their rims to provide further cold protection.

I’ll save some leaves to protect strawberry plants. Their insulating blanket won’t go down until weather turns colder, with the soil frozen an inch deep, or else their evergreen leaves will rot beneath the leaves.

I’ll be digging out or cutting down a number of woody plants, some even 10 or 20 years old, in the next few days or weeks to make way for better ones. (Ruthless!) Anna hardy kiwifruit, short for Annanasnaya, grows very well but ripens a bit late and doesn’t have quite as good flavor as my other varieties: Geneva, MSU, and Dumbarton. So out it goes. The same goes for Mars, Concord, and Cayuga White grapes; their flavor isn’t up to snuff. And Halle’s Giant, Lewis, and Clark filberts, except that their shortcoming is their susceptibility to the disease filbert blight.

A 5 gallon bucket filled with equal parts sifted compost and soil will be ingredients for any potting soils I’ll need for seedlings from midwinter on. For the finished potting soil, I’ll mix in another 5 gallon bucket with equal parts peat moss and perlite.

One sunny day soon I’ll lean pitchforks, rakes, and shovels against the garden carts and brush them with linseed oil diluted with equal parts paint thinner. Tool handles, readied After the handles have been wiped down, 10 minutes later, they’ll be in good condition for at least another year.

Pruning hardly needs to be added to my punch list. I’m reminded about this annual job every time I look out the window or walk out the back door.

Deer at Bay

Protecting some of my trees and shrubs from animals doesn’t make it to the punch list either — because it needs to be done by now! Young pears (Concorde, Abbe Fetal, and Lady Petre) and apples (Liberty, Macon, Hudson’s Golden Gem, Ashmeads Kernel, and Pitmaston Pineapple) already have their hardware cloth and/or plastic collars protecting their bottom couple of feet of growth.

What about branches higher up, the ones the deer would find tasty. Thanks to fencing at both the north and south ends of my property, a couple of Deerchaser battery-powered repellants, two outdoor dogs, and vibes from me, deer rarely venture on site. But, as I discovered this past summer, just one deer on just one night can do a lot of damage to a young tree.

So this year I’m putting 5 foot high by 3 foot diameter cages of 2×4 welded wire fencing around my young apple trees. Deer protection, high fence The pear trees, close to the house, don’t get bothered. The problem with such cages is that it’s a hassle to weed or prune within the cage — both very important for young trees. Two metal stakes, each a 5 feet length of EMT electrical conduit, woven into part of fencing on opposite sides allows me to slide the fence up and down to get inside a cage to work. These trees, which are replacing my very dwarf apple trees, are semi-dwarfs which can fend for themselves once they get above 5 feet. Then I’ll remove the cages.

Memorables, for Vegetables

And now, some notes for next season’s vegetable garden . . .

Reduce the number of pepper varieties to those that perform and taste best here: Sweet Italia,

Italian Sweet peppers

Carmen, and Escamillo. And stake them right from the get go.

Plant a greater proportion of tight-necked onions, such as Patterson, New York Early, and Copra, to avoid bacterial diseases.

Plant less bok choy; no need to be inundated by them just because the space is available.

Keep an eye out for whiteflies and caterpillars on cabbage family plants; act sooner rather than later to keep them in check.

Plant more Shirofumi edemame; 30 feet of bed should be about right, they need a long, hot season.

Try King of the Garden Limas again, but plant even earlier indoors.

Get Out!

Okay, time to get outside to work on my punch list before any snowfall limits the possibilities.

Autumn’s Leaves

December 15, 2017/2 Comments/in Design, Planning/by Lee Reich

Wherefrom the Colors?

Autumn is a season when New York’s Hudson Valley, and much of the Northeast, unfolds in all its glory. Not this autumn, though. What’s going on in the leaves this year? Is there anything I can do about it?.

Chlorophyll is what makes leaves green, but hidden behind that green, all season long, are some of autumn’s colors. Chlorophyll must be continually synthesized for a leaf to stay green. The shorter days and lowering sun of waning summer are what trigger leaves to stop producing chlorophyll and let some of the other colors come to the fore.

Yellows and oranges, no longer masked by chlorophyll green, come from carotenoids, which help chlorophyll do its job of harvesting sunlight to convert into plant energy. Thank carotenoids for the warm, yellow glow they give to gingko, aspen, hickory, and birch leaves.

Gingko

Tannins are another pigment, actually metabolic wastes, that all summer are hidden by chlorophyll. Their contribution to the fall palette are the season’s subdued browns, notable in some oaks and enriching the yellow of beeches.

Because leaves harbor carotenoids and tannins all summer long, nothing particular about autumn weather should either intensify or subdue their autumn showing. I’m blaming this autumn’s poor show on the season’s extended warm weather. It was slow to arrest chlorophyll production and induce leaf drop. A couple of hard freezes brought the whole works to a screeching halt, so instead of showy yellow leaves, my witchhazel’s stems are now “adorned” with wrinkled, green leaves frozen in place. Other trees and shrubs suffered a similar fate, and their frozen, green leaves are dropping without any fanfare.

Autumn color also spills out reds and purples, most evident in red maples and some sugar maples, scarlet oak, sourwood, blueberry, and winged euonymus. Those reds and purples come from anthocyanins, yet another pigment. Except for trees like Purple Fountain beech and Royal Purple smokebush, whose leaves unfold dusky red right from the get go in spring and remain so all season long, in most leaves anthocyanins do not begin to develop until autumn.

Sugar maple

Anthocyanin formation requires sugars, which accumulate best with a combination of warm, sunny days to maximize photosynthesis, and cool, but not frigid, nights to minimize nighttime burning up of accumulated sugars. A cloudy, rainy autumn means less red because less anthocyanin is formed, and any that does form is diluted. Warm nights, such as characterized much of autumn, reduce anthocyanins by burning up much of each day’s sugar production. The result: Less reds and purples, as evidenced by the blah color of this year’s blueberries in my garden and maples in the forests.

Can We Make the Color Better?

Is there anything we can do about the autumn show?

Here in the garden, my role in the autumn show is to plant trees genetically programmed for good autumn color. Colorful trees and shrubs include goldenrain tree, hickory, ironwood, and black tupelo. Certain varieties within each species might pack a bigger wow than the others. Hence the spicebush variety Rubra, brick red in fall, or Wright Brothers sugar maple, whose leaves become a mottling of gold, pink, orange, and scarlet. Other especially colorful varieties include Autumn Flame and October Glory red maple, Commemoration and Legacy sugar maple, Autumn Gold and President gingko, and September Beauty Chinese sumac.

Japanese maple

Despite this autumn’s weather, fothergilla and Japanese stewartia both managed to look as flamboyant this year as in others. If you believe that, going forward, autumn weather is going to bring on less spectacular color, choose varieties that originated from more southerly latitudes.

And if warmer autumns are going to be one effect of global warming, we can help the autumn show beyond our gardens, in the forests, by traveling less or more efficiently, using less plastic and other petrochemicals, eating more locally grown food and less farmed meat, investing in energy-efficient appliances and renewable energy, etc. (For more, see https://www.conserve-energy-future.com/stopglobalwarming.php.)

Back in the garden, my other role in ratcheting up the reds and purples is to make sure that leaves bask in light. I plant a tree where light is adequate (for that species) and, as necessary, prune so that branches don’t shade each other. Street lights don’t count as light, and actually have a negative effect, disrupting the signal that days are getting shorter and it’s time to slow chlorophyll production.

Lee’s New Book!!

Knowing something about how plants work can make gardening more interesting as well as make the landscape prettier and vegetable gardens more productive. And that’s the thrust of my upcoming book, The Ever Curious Gardener: Using a Little Natural Science for a Much Better Garden, to be published in early spring of 2018 but available for pre-order through Amazon or, signed, from me.

Some Fruits and a Ornamental Veggie

Happy Blueberries, Happy Me

My sixteen blueberry plants make me happy, so I make them happy. (They made me happy this year to the tune of 190 quarts of berries, half of which are in the freezer.) I don’t know how much work bearing all those berries was for them, but I just finished my annual fall ritual of lugging bag upon bag of leaves over to the berry patch to spread beneath the whole 750 square foot planted area. Blueberry fruit cluster

I don’t begin this ritual spreading until the blueberries’ leaves drop. Then, old leaves and dried up, old fruits are on the ground and get buried beneath the mulch, preventing any disease spores lurking in these fallen leaves or fruits from lofting back up into the plants next spring. Rainy, overcast summers or hot, dry summers or any weather in between — my bushes have never had any disease problems.

In past years, I did do two things before spreading that mulch. First, I spread some nitrogen fertilizer: my universal pabulum, soybean meal, at the rate of 2 pounds per hundred square feet. And second, I spread some sulfur, at about the same rate, to keep the soil acidic. After many years of mulching, the soil has built up an ample reserve of organic nitrogen — evidenced by the plants’ 2 to 4 feet of new stem growth each year. So I no longer add extra nitrogen.

With all those years of mulching, levels of decomposed and decomposing soil organic matter have greatly increased the soil’s buffering capacity for acidity. That means that I no longer have to pay such close attention to acidity, so I rarely add sulfur anymore.

Sammy also likes the mulch

Besides all these other benefit, the mulch has created a soft root run that retains moisture, just what blueberries’ thin roots really like. Fruit is borne on shoots that grew the previous season, so each year’s vigorous new growth translates into a good crop in the offing for the next year.

New York Bananas

Although the crop seemed paltry at first this year, by the time autumn came around, pawpaws were in abundance. This uncommon fruit is the northernmost member of the tropical custard apple family, and the fruit does indeed taste very tropical — a flavor mix of banana, mango, avocado, and vanilla custard — even though it’s easy to grow and native throughout much of the eastern U.S.. Pawpaw, like crème brûlée

Two trees would be adequate for most households; I have about 20, just so I can learn more about them and their individual differences. That makes for a lot of pawpaws! (I test market most of them.) Row of pawpaw & black currant

Pawpaw fruits are very variable in both size and flavor even among the branches of a single tree. One year, I tried thinning the fruits to see if that would increase size of remaining fruits, as it does with apples and peaches. Pawpaw has a multiple ovary so each blossom can give rise to as many as 9 fruits. The small fruits are hard to see because they match so closely the green color of the leaves, so I didn’t thin as many as I had hoped. That said, at season’s end, fruits on thinned clusters seemed no larger than fruits on unthinned clusters.

Beginning around the middle of September, I began harvesting the first fruits. I picked some up from the ground and picked some softening ones from the trees, all of which continued through October. By putting them immediately in a cooler at 40°F, I still had good fruit into the middle of November.

Scarlet Runners

Every year I fear that at season’s end I’ll remember something I forgot to plant. This year it was scarlet runner beans. Scarlet runner bean flower

Despite the “bean” in the name, I’ve grown this vining bean, as do most people, primarily as an ornamental, for its scarlet blossoms. I occasionally eat the fat, hairy, yet delectable green beans.

Every year I collect some of the matured black and pale purple, calico seeds for replanting the following year. One year, I decided to cook up some of these seeds and taste them. Scarlet runner bean seeds are quite tasty (and, I learned prior to eating, nonpoisonous). Scarlet runner beans

Next year I’ll remember the scarlet runners. My yard will be aflame in scarlet flowers and, because the plant is pest-free — even to Mexican bean beetles — I expect to reap a bumper crop of beans.

Leafy Exercises

November 22, 2017/9 Comments/in Gardening, Planning, Soil/by Lee Reich

A New Exercise: Un-Rei-King

A few years ago I wrote that, among the many benefits of gardening is the opportunity it offers for varied, productive exercise. At that time I highlighted rei-king (ray-KING). Now, let’s add un-rei-king to join rei-king, zumba, cardiofunk, and other ways modern humans build and maintain sleek, fit bodies. Leaf bags with pawpaws

In fact, many people, including couch potatoes and nongardeners, practice rei-king this time of year. You can see them practicing this sweeping motion on their lawn amidst gathering piles of leaves.

Un-rei-king is a more rare form of exercise, of which I am a practitioner. Rei-kingers gather those piles of leaves that are a byproduct of their exercise into large bags, then muscle them curbside. I gather said bags, muscle them gardenside, and launch into un-rei-king. That is, I employ a similar motion to rei-king, except more jagged and with a pitchfork, spreading the leaves once I have freed them from their baggy confines.

Feeding the Soil to Feed the Plants

Exercise aside, my goal is to blanket the ground beneath one row of pear trees, a large bed of gooseberry bushes and grapes, and another long row of pawpaw trees and blackcurrant bushes with 6 to 12 inches of autumn leaves. That fluffy blanket will hold autumn’s warmth in the soil long after bare soil has frozen solid to a few inches depth.

I have to practice un-rei-king every year in November because by this time next year, that leafy blanket will have pretty much evanesced into thin air, literally. Leaves are composed mostly of carbon, hydrogen, and oxygen which becomes, over the course of the year, carbon dioxide and water vapor.

All this may seem like wasted effort (except for the exercise), but it’s not. The transmutation of leaves to carbon dioxide and water happens as bacteria, fungi, worms, and other soil organisms gobble up the leaves. Mostly, these creatures are beneficial, helping plants to fight off pests.

Leaves are mostly, but not only carbon, hydrogen, and oxygen; also contained therein are a slew of minerals needed by plants. In addition to feeding soil life, as the leaves decompose they’re also fertilizing the ground. More than that, natural, organic compounds are being formed that help make minerals already in the soil more accessible to plants.

All this living activity also releases into the ground other natural, organic compounds that aggregate soil particles to create pores for good aeration as well as to act spongy to help the ground, at the same time, hold moisture.

All of which is to say that after years of un-rei-king, my soil is soft, fluffy, moist, and very much alive. The pear trees, gooseberry bushes, etc. love it.

Uh-Oh, Mice

Meadow mice also enjoy the fluffy blanket, beneath which they can nest — and feed on plant roots and bark! So as I lay down that blanket, I’m also putting an 18-inch high cylinder of hardware cloth or some commercial wrap around the bottom of the tree trunks to fend off the mice.

I’ll also keep the leaves a few inches back off the trunks to keep mice at bay and avoid rotting of the trunk. Such precautions are unnecessary for shrubs, whose fresh supplies of stems that grow each spring at ground level can replace any chewed ones. (That’s why they are shrubby.)

And Some Leaves — For Next Year

Not yet finished with leaves. Every autumn a local landscaper dumps a truckload of vacuumed-up leaves here. On that pile I grow watermelons all summer long. By now, the leaf pile has about half-decomposed into “leaf mold” which is pretty much the same thing as compost. Except rougher, because it’s not yet in the final stages of decomposition.

Being richer in nutrients than freshly fallen leaves, leaf mold is just the ticket for loading into a cart for mulching some special plants: a young chestnut tree, filbert bushes, and semi-dwarf apple trees. Plus, it brings along all the aforementioned benefits of raw leaf mulch. Mulch, leaf mold on pear
