ROSES AND STRAWBERRIES AND — OH NO! — HONEYBERRIES

June 10, 2021/22 Comments/in Flowers, Fruit/by Lee Reich

Roses, Oh Yes

I bake really good bread, but “man can’t live by bread alone.” Sometimes, you’ve got to “stop to smell the roses.” Enough with the quotations! But back to the roses.
Roses in a vase
A love of roses has crept up on me over the years, due mostly to changes in kinds of roses available. Up until about 30 years ago, hybrid teas were pretty much the only roses on the block. These plants’ gangly stems are each capped by a vividly colored, fairly stiff, formal blossom whose petals wrap together into a pointy peak. You see where I’m going: hybrid teas are ugly, to me at least.

Also available were grandiflora and floribunda roses. Grandifloras are like hybrid teas, except their stems end with clusters of a few, but smaller, blossoms. Floribunda roses have even larger flower clusters of even smaller flowers. Despite being bushes more full with flowers than hybrid teas, grandiflora and floribunda flowers are still rather prim and proper except for their traffic-stopping colors.

Then so-called species and old-fashioned roses entered the scene, roses that are as nature made them or only slightly hybridized. These roses constitute broad groups, but generally, what they have going for them are more subdued — think pastel — colors and more blowsy blossoms on more heavily branching, fuller-bodied, shrubs.

The downside to species and old-fashioned roses, even if you like their blossoms and their growth habits, is that many bloom only in the spring. Hybrid teas pump out blossom after blossom all summer long.

Rose d’Ipsahan

Enter Rose de Rescht, my first old-fashioned rose, given to me by a local, fellow gardener. Ann told me that this rose variety had soft pink flowers and heavenly scent. She was right about the appearance and fragrance, wrong about the name. After years of sleuthing, I’ve identified the rose as Rose d’Ispahan, probably originating in Persia but first discovered in a garden in Isfahan, Iran, renowned for its gardens and roses.

If I had to grow only one variety of rose, Rose d’Ispahan would be the one, for the beauty of its flowers, for its intense fragrance, for its cold-hardiness, for its lack of large thorns, and for its pest resistance. And that’s even though it blossoms only in spring. (It does so over a long period, though.)

Rose d’Ipsahan

But I don’t have to grow only one variety of rose. My other favorites are some of rose breeder David Austin’s varieties which combine the pest resistance and repeat blooming of modern roses with the blowsy, fragrant, pastel colored blossoms and full-bodied shrubs of old fashioned roses. My currant, and perhaps all-time, favorites are Lady of Shallot and, in my opinion needing a more euphonious name, Golden Celebration.

Golden Celebration rose

Both sport yellow — no, Golden! — blossoms, some apricot in those of Lady of Shallot, and a rich yellow, all contained in a petal-filled cup-shape in those of Golden Celebration. Another of my favorites, Lady Judi Dench, never woke up in spring a year ago; perhaps it was the cold, perhaps something else.

Lady of Shallot rose

I also grow another David Austin Rose, LD Braithewaite, with deep red blossoms and dark green, slightly reddish leaves. Not my favorite as far as appearance but this rose is very cold hardy and pumps out tons of blossoms almost all season long.

And Strawberries, Oh Yes

Strawberries and roses On to strawberries. I’m growing three kinds: the Pineapple Crush variety of white alpine strawberries; the Earliglow variety of garden strawberry; and a few varieties of vescana strawberries, which are hybrids of garden and alpine strawberries. This also is the order, starting with the best, of flavor for the three types.

Why do I grow anything but the best? Because alpines are so small that it’s hard to fill a bowl with them. I grow vescanas, for the first time this year, because I never grew them before.

The Earliglow berries taste good and do quickly fill a bowl, ideally yielding one quart of berries per plant over the course of the season. Except this year, a problem has surfaced. Leather rot is a fungal disease (Phytophthora cactorum) that rears its ugly head — infected berries that taste bitter and have white patches that turn brown — usually following excessively wet periods from late spring to early summer, which is odd because weather has been on the dry side. Also odd because I’ve never seen the problem here before.
Strawberry leather rot1
Which brings me back to vescana and Pineapple Crush. Both are very disease resistant, and vescana berries are almost as big as garden strawberries, so I’m thankful to have them, even if they do taste like canned strawberries.

And Honeyberries, Oh NO!

After three weeks of hanging on (the berries, not me), honeyberries, which are edible honeysuckles, are ready for a fair tasting. I wrote previously about the awful flavor of this new fruit and was instructed to let the berries hang till dead ripe.

The berries sampled this year were so ripe that each had to be plucked from the branch with my palm facing upwards beneath the berry; a mere touch would cause ripe ones to drop.

Rat-a-tat-tat-tat-tat (a drum roll). First to be tasted was the variety Solo. Reaction: spit it out quickly. Tart with bad flavor. Second fruit tasted was Sugar Mountain Blue. Also spit out, but not quite as quickly. And finally, Sugar Mountain Eisbär. Although retained in the mouth and having a hint of sweetness, this one, like the others, had bad flavor.

The flavor of honeyberries is allegedly like a mix of blueberry and raspberry. Not so! If you have space, plant blueberries or raspberries instead.

MARKING SPRING’S ONWARD MARCH

April 28, 2021/8 Comments/in Flowers, Planning/by Lee Reich

It’s spring, a time when a man’s thoughts turn to . . . flowers, of course. (At least this man’s thoughts, some of them, do.) Sure, I’ve been reveling in the colorful progression of blossoms beginning, this year, with cornelian cherry and hellebore on about the first day of spring, and moving on to forsythia, plum, Asian pear, flowering quince, European pear, cherry, and — probably by the time you read this — apple followed by shipova. All this is the flamboyance of spring.

This year, I’ve also been admiring a few of the more subtle flowers of spring.

MAPLE BEAUTIES, AND OTHERS

Some of the maples are now in bloom. Sugar maples (Acer saccharum) is perhaps the prettiest and most useful of the maples. Unfortunately, it’s also the least tolerant of compacted or wet soils, or a warming climate. The beauty of sugar maples lies not just in the leaves’ autumn show of color or the majestic form of an older tree.

Acer, sugar maple flowers, closest

Check out sugar maple’s flowers. They dangle like pale green wisps of lace from the branches, subtly attractive in their own right viewed up close and especially so in the forest. As a prominent species in the Shawangunk Mountains here in New York’s Hudson Valley, en masse the trees suffuse the view of the mountainside from afar with a welcoming softness.
View of Shawangunk Mountains
Red maple I(Acer rubrum) is another very attractive — and very variable — maple. The showiness of its blossoms relies on color, a deep, deep red. The blossoms arrive very early, and what I’m seeing is the aftermath of the blooms, clusters of red seeds, their wings spread as if ready to fly, which they soon will.

Acer, red maple seeds

Not nearly as appealing, in many ways, as a tree, but even more cosmopolitan in its environmental tolerance, is silver maple (A. saccharinum). Flowers are blah. The tree tends to drop branches. No autumn color to speak of, either. It is fast-growing, though. As expected, the roots are equally fast growing and shallow. I once lived in a house in front of which grew two giant silver maples. One day, while investigating a clogged water line in the crawlspace, I came upon what looked like a thick, half-buried leg of an elephant. It was one of the silver maple’s roots.

The last —unfortunately too common — maple around here whose flowers or fruits I’ve been noticing is Norway maple (A. platinoides). This species was once widely planted as an ornamental but is now frowned upon because it casts a lugubrious shade beneath which grass or, in the woods, many wildflowers have difficulty growing. It’s an invasive plant that can displace sugar maple in wild settings. In autumn, leaves hang on for a long time, long enough to look forlorn after being burned by a freeze or, barring that freeze, for occasional leaves to begin turning a sickly yellow before naturally dropping.

Norway maple flowers

Norway maple’s flowers, viewed up close, are surprisingly attractive, something like those of sugar maple as clusters of them hang downward on stalks, something like a chandelier. But with none of the grace of sugar maple’s long flower stalks.

PHENOLOGY

I believe I have earned the title of “phenologist.” No, I haven’t been measuring skulls to assess character, which is the realm of phrenology. Phenology, which I have been practicing, is the study of climate as reflected in the natural cycles of plants and animals.

For the past 30 plus years, I have recorded the dates on which various plants have blossomed or ripened their fruits. My interest has been horticultural: In spring, plants blossom after experiencing a certain accumulation of warm temperatures; fruit ripening reflects, to a lesser degree, further accumulation of warmth. The amount of warmth needed to bring on those flowers or ripen fruits varies with the kind of plant, sometimes even with the variety of plant.

Forsythia in bloom

Depending on late winter and spring weather, blossoming dates for various plants can vary quite a bit. Microclimate also plays a role, so I’ve tried to always note blossoming on the same plant from year to year. This year, forsythia bloomed about April 9th, which is pretty early as compared with previous years although in 2010 it bloomed on April 1st and that was topped by 2012’s bloom on March 20th. Contrast that with 1984, when it bloomed on April 25th! On average, bloom dates have crept earlier and earlier over the years, a reflection of global warming.

In the garden, seeds and seedlings shouldn’t be sown or transplanted until the soil has warmed sufficiently, which likewise reflects that accumulation of warmth. Some seeds or seedlings require more warmth before they can grow (or survive) than do others. Knitting all these phenomena together, I plant, for example, lettuce seeds when forsythias blossom, broccoli transplants when pears blossom, and sweet corn when honeysuckles blossom.

Pears in bloom

These sunny days and balmy temperatures are heavenly – except that they’re also coaxing earlier blossoms from my fruit trees, blossoms that could get burned by subsequent frosty nights. The earlier these trees bloom, the more chance for those blossoms to get burnt on a subsequent frosty night.

The historical average date of the last killing frost around here is about the middle of May. Even warming trends might accommodate a frosty night or two that can wipe out a whole season’s harvest of apples or peaches, the first of which is about to bloom and the second of which has bloomed.

Still, it’s a glorious time of year, with no small contribution from the maples.

SOUTHERN FRANCE, IN SCENT AND SIGHT

April 1, 2021/9 Comments/in Flowers, Vegetables/by Lee Reich

Heaven Scent Flower

I trace the origin of my present obsession with growing carnations – big, fat, fragrant carnations (Dianthus caryophyllus) – to the movie, Jean de Florette, that I saw back in 1986. Not that I aspire to labor under the weight of hauling water long distances to care for my plants, as did Ugolin. And not that I’m hoping to get good money selling the cut flowers at a local market.

Actually, my only memories of the film are of the charming countryside of Provence, of Ugolin crouching over the plants and lavishing them with care, and of the pretty pink flowers. Come to think of it, I’m not sure Ugolin’s carnations even got as far as the flowering stage. Anyway, in my mind’s eye I see those pink blossoms and smell their spicy perfume.
Carnation, fragrant and pretty
With good soil and ample water, my carnations have an easier time of it that did Ugolin’s. Too easy, perhaps. Carnations don’t need or like overly rich or wet soil. When it came time to plant out my seedlings, I recalled those scenes in Jean de Florette. The ledge of soil held up by a stone retaining wall along the south side of my house provide the good soil drainage and sunlight that suits carnations. Lavender, another Mediterranean plant growing on a wall nearby, will help make the carnations feel right at home.

The biggest threat to my carnations is winter cold and wetness. And even then, these carnations, although technically perennials, are typically short-live perennials that peter out after a couple of years. Luckily, they are easy to grow from seed or root from cuttings.

Like Ugolin, I’ll soon be carefully nurturing some new seedlings. Whether planting, picking, taking cuttings, or preparing them for winter, I’ll also be hunched over my carnations and lavishing them with care, in the months ahead. It’s worth it, for the pastel flowers, and especially for the flowers’ heavenly scent.

And Some Things for the Other Senses

What’s the attraction of southern Europe? The climate there is so different from here in the Wallkill River valley, yet I am attracted to and keep trying to grow Mediterranean plants such as carnations, figs, pomegranates, lavender, black mulberry, and rosemary. All these plants thrive in dry summers and cool, not frigid, winters; minus 20°F is not an uncommon low winter temperature here.

Cardoon, last year

Add to the roster here artichoke and cardoon, two more Mediterranean plants that I set out last spring, for the artichoke, the spring before for the cardoon. (The very mild temperatures of the previous winter let the cardoons survive their first winter outdoors.) That was after sowing each plant in later summer and having it winter in the very cool temperatures of my greenhouse, which provided the vernalization the plants need to flower their first season outdoors.

Both cardoon and artichoke grow as a whorl of spiny leaves from the center of which rises a main flower stalk with smaller flower stalks branching off lower down. Like carnations, they are short-lived perennials. Like carnations, they are easily propagated, in this case by seed or by offshoots that grow at the base of the plant

Cardoon in bud

Like carnations, the biggest threat to artichokes and cardoons around here is winter wetness and, especially, cold. Winter cold will assuredly kill them unless they are protected in some way. To that end, late last fall, I cut down the plants and covered each with a large, inverted flowerpot in which and on which piled leaves for insulation.

Cardoon & artichoke protected for winter

During the warm spell a week or so ago, I pulled back the leaves and uncovered the plants. Cardoon leaves had sprouted more than a foot high within their winter home! Without light, the leafy stalks were ghostly white.

Cardoon, after winter

That’s okay; cardoon is sometimes purposely blanched to make its flavor more mild. A few days of light will green them up. That’s okay too; I’m growing cardoon for its bold visual presence — last year the plants leaves formed a 3-foot-high, blue-green, mound of spiny leaves up the center of which rose flower stalks at the top of which opened blue flowers resembling enormous thistles.

Cardoon flower

As for the artichokes: Not a sign of life. Perhaps winter cold or moisture did them in. Perhaps mice lunched on the roots. Perhaps there’s life beneath the ground, still to awaken. I’ll keep my fingers crossed.

BEE GLORY, GONE (FOR NOW)

March 24, 2021/5 Comments/in Flowers/by Lee Reich

Arnold’s Promise?

I miss the bees. No, they’re not gone from here because of Colony Collapse Disorder (CCD), widely responsible for the loss of bees. Most years, they would have been here and perhaps gone on to greener pastures by now.
Honeybee on witchhazel
The bees come for my witchhazel, and the reason for their absence this year is because my witchhazel didn’t bloom. It usually blooms in late winter or very early spring. And it won’t bloom this season at all. The reason is because it bloomed last fall.

It’s not uncommon for an early spring bloomer such as witchhazel to jump the gun and bloom in fall. And the cause for this behavior is growing conditions through summer that send the plant into a kind of sleep, then fall conditions that all of a sudden shake the plant awake. My guess is that the plant considered the very dry weather last summer an ersatz winter, and cooler and moister conditions in fall were an ersatz spring.

Witchhazel, spent blooms from past autumn

I’d prefer, and the bees also might prefer, for the plant — Arnold’s Promise variety of witchhazel — to bloom on its usual, this side, of the calendar. We’re all much hungrier now for all that visual and aromatic glory. The bees seem happiest with the spring blooms, making the bush all a-buzz with their frenzied flitting moving from flower to flower. These early blossoms provide the nectar and the pollen they need to get going in spring.

Witchhazel in full bloom in past years

What’s So Good About Honeybees?

Honeybees are much more valuable for their pollination services than for the honey and beeswax we sneak from them. Many crops – almost all those with showy flowers – need the pollination services of bees in order to set seeds or make fruits.

I once kept bees, so can attest to the fact that they make very interesting pets. Their social organization rivals that of any other creature. (Humans are not even in this running.) Each bee knows and does his or her job. The hive’s sole queen leaves the hive but once in her life to get fertilized by males, after which the latter, their genitals ripped from their bodies, die. Guard bees protect the entrance from interlopers.

On calm, balmy days, workers spend their days seeking out and gathering nectar and pollen from flowers. A worker, upon finding a good source of nectar and pollen, returns to the hive and does a dance that communicates to other workers the location of that bounty. This bee “language” is so evolved that different varieties of bees have different “dialects.”

For a fascinating description of the experiments that led to the discovery of those “bee dances,” take a look at the book The Dancing Bees by Karl Von Frisch, who, in 1973, received the Nobel Prize for his work with bees.

Luckily, There are Other Bees

Looking at those ecstatic bees on my witch hazel bush years ago, it struck me that perhaps what I was looking at were not, in fact, honeybees. My personal observations here on the farmden notwithstanding, honeybees are, in fact, on the decline. But they’re not the only bees on the block. Honeybees weren’t even “on the block” a few hundred years ago because they’re not native to North America.

North America has plenty of wild bees, though, almost 4000 species of them! Our wild bees – including, for example, carpenter bees, bumblebees, orchard mason bees, and hornfaced bees — are very efficient pollinators, going outside to work during weather in which honeybees remain huddled in their hives. These native bees get up earlier in spring and earlier each day, and don’t need the calm weather (wind less than 15 mph) and warm temperatures (greater than 55 degrees F) demanded by honeybees. Native bees also are more gentle than honeybees, rarely stinging. They don’t, however, make honey or beeswax.

Bumblebee on blueberry plant

Unfortunately, native bee populations are also on the decline these days, due mostly to habitat destruction and pesticide poisoning. Some people build special nestboxes for these helpful insects, which require nothing more than tubes in which to lay eggs, anything from bundles of straws to wooden blocks into which holes have been drilled.

Whatever I’m doing that has kept those bees on my witchhazel happy will have similar effect whether the bees are honeybees or native bees. Because some native bees nest in the ground, our gardening practices can influence their well-being. The website of the Xerces Society details the effects of a number of gardening practices on native bees. Tillage, for example, can be detrimental, as are the pesticides copper sulfate, sulfur, and rotenone. Maintaining wild habitats is also important to their survival.

I’m hoping next winter or spring to see my Arnold’s Promise awash in fragrant, yellow blossoms and all abuzz with bees, whether honeybees or native bees.

ALMOST LIKE SUMMER

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

Fresh Veggies

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

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

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

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

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

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

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

Summer Berries

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

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

Olfactory Romance

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

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

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

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

COMPOST, KALE, A FLOWER, AND AN ODD ONION

September 16, 2020/8 Comments/in Flowers, Vegetables/by Lee Reich

Ins and Outs of Compost

Mostly, what I’m doing in the garden these days is making or spreading compost. Lots of good stuff — old vegetable plants, hay, weeds, rotted fruits — is available to feed my compost “pets.” And compost spread now has the ground ready for planting in spring.

Do you have any questions about composting? Want to know how to make best use of co compost pile being watered mpost? Interested in details about how to make gourmet compost? This is a reminder that on Wednesday, September 23, 2020 from 7-8:30pm EST, I’ll be hosting a webinar about composting. For more information and registration, go to https://leereich.com/workshops.

A recording of the webinar will be available for a limited time period to anyone who registers but can’t make it to the live presentation.

Kale, You’re More than Beautiful

I’m lucky enough to have a French window of two big, inward swinging panels out of which I can look over my vegetable garden every morning. Oddly enough, the garden bed that is catching my eyes these mornings for its beauty is the bed mostly of kale plants.

No, it’s not a bed of colorful, ornamental kale, not even a reddish kale such as Russian Red. I grow just plain old Blue Curled Scotch kale, which is no more bluish than any other kale, or any other member of the whole cabbage family for that matter. What catches my eye each morning is the way the curly leaves flow together like an undulating wave of verdant frilliness.
Kale, from upstairs window
My vision could be swayed by my knowing that kale is such a healthful vegetable, being especially rich in calcium and vitamin A. Or the fact that it’s so easy to grow. I sowed the seeds in early March, set out transplants out in early May, have been harvesting it since the end of May, and will continue to do so probably well into December. (Another bed of kale, which I seeded right out in the ground at the end of May, is also looking good.)

Unlike broccoli, whose prime is past once buds open into flowers, or cabbage, which splits if left too long, kale doesn’t need to be harvested at just the right moment. It just keeps growing taller, with more leaves, if left alone.

The only thing kale needs protection from is rabbits and woodchucks, like most vegetables, and from cabbage worms. A fence and two dogs keep rabbits at bay. One or two sprays of the biological pesticide Bacillus thurengiensis, sold commercially under such trade names as Thuricide and Dipel, is all that’s needed for the worms (they’re actually caterpillars, not worms). Or nothing. Some years, damage is light enough so that no control is necessary.

What more could I ask for from a plant: good looks, good health, and good flavor?
Row of kale

Kiss Me Over the Garden Gate

I take it upon myself to personally promote the revival of an old-fashioned flower: kiss-me-over-the-garden-gate (Persicaria orientalis). It’s big, it’s beautiful, and it’s distinctly old-fashioned.

If you know the weed called smartweed, you have a hint of what kiss-me-over-the-garden-gate looks like. Smartweed is a trailing weed, usually no more than a foot or so high, with what look like small droplets of pink dew at the ends of its stems.

Kiss-me-over-the-garden-gate looks like smartweed on steroids, the “droplets” the size of bb’s and, rather than trailing, the plant rises with robust arching stems to more than seven feet high. It’s just the right height and form for growing next to a garden gate, which is where my plants sometimes grow.
kiss me over the garden gate
Kiss-me-over-the-garden-gate is a little hard to get started because the seeds germinate slowly and erratically. My plants thankfully live up to their reputation of being self-seeding annuals. The self-seeding plants come up more robustly than the coddled few seedlings I used to transplant each year.

Kiss-me-over-the-garden-gate’s self-seeding habit is restrained enough to keep it from being frightening. All I do each spring is weed out the few extra plants, as well as those that stray too far from my garden’s gate.

Evergreen Onions

For many years, in addition to starting onions from seed, sown in February, I also would go the more conventional route and bought a few “sets” for planting. Sets are those small bulbs that grow first to become scallions, which are mostly leaf, then go on to fatten into bulbs that can be harvested and stored.

Nowadays, instead of planting sets for scallions, I grow bunching onions, yet another type of onion, one that never ever makes fat bulbs. I’ve sown them in February for later transplanting, or directly in the garden. They always remain scallions, never bulbing up, and multiply by growing new baby plants at their bases.
Evergreen onion
The variety I grow, Evergreen Hardy White, can allegedly live through winters here. Come spring, the plants can be divided to make more scallions for eating and for growing. (I’ve always eaten them all; this year I’ll leave some to challenge their winter hardiness.)

Tops of my bulbing onions dried down and were harvested weeks ago, but these bunching onions never cease to maintain their fresh, green scallion-y character.

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°.

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.“

Catalog and Weather Watchin’

January 8, 2020/15 Comments/in Flowers, Planning, Vegetables/by Lee Reich

Armchair Gardening

Pretty much the only “gardening” I’m doing now is thumbing through the seed catalogs arriving in dribs and drabs in my mailbox. I’ve ordered and received what I thought I’ll need, but you never know; maybe there something else interesting out there to grow.

Among the most fun of these catalogs, and strictly for the plant-crazed, is “The 2020 Ethnobotanical Catalog of Seeds,” which used to be called Hudson’s Seed Catalog. The catalog originates in the Santa Cruz mountains of California (once home to Ken Kesey) but offers seed from all corners of the world. Only recently have they come online, at www.jlhudsonseeds.net.
Hudson catalog
I’ve ordered from this catalog for decades, each winter pleasurably and slowly wading through the almost 100 black-and-white pages of small print listings of botanical names and descriptions. For this first run through the catalog, I sit poised with red pen, ready to make a star next to any seed listing that looks particularly interesting. After I go through the whole catalog once, I’ll re-examine all those starred listings and select which seeds to actually order and grow.

Judging from what I’ve so far starred, I seem this year to be drawn to scented plants. Achlys triphylla, also known as vanilla-leaf or sweet-leaf, is one such plant: “Dense spikes of tiny flowers held above the trifoliate fan-shaped leaves. Moist woods from B.C. to California. The sweetly fragrant leaves were highly valued by settlers, who hung bunches in their houses. Sow 1/4″ deep in rich woodland soil, and keep moist. Slow to germinate.”

Another is Adenophora lilifolia, also known as ladybells. This one is described as “sweet-scented light blue 1/2″ wide bell-shaped nodding flowers borne profusely in summer. Very hardy perennial to 1-1/2 to 3 feet, with round, heart-shaped basal leaves. Eurasia. Cultivated in Japan for the thick, edible roots. Germinates in 2 weeks.” For only $2.50 a seed packet, oodles of each of these plants can be growing in and perfuming my backyard this summer.

It’s not just visions of fragrant, comely, or tasty plants that make this catalog fun to read. Berkheya purpurea is native to Africa, with a common name Zulu warrior. How many plants conjure up an image like that!? The plant seems to me less warrior-like, with flowers that are large, silvery-blue to lavender daisies with dark centers. Interesting, but I don’t need another daisy for now.

Short quotes interspersed throughout the catalog set the tone and are food for further thought. Here’s one from Thomas Jefferson: “It does me no injury for my neighbor to say there are 20 gods or no God. It neither picks my pocket nor breaks my leg.” Or, going back 17 centuries, to Aesop: “Any excuse will serve a tyrant.” And then forward, to General Douglas MacArthur: “ If you win, you stand only to lose. War contains the germs of double suicide.” Or, to another American general, Dwight Eisenhower: “Things are more like they are today than they have ever been before.”

So far, I’ve only gotten as far as “D” in the seed listings. There’s still time.

Where’s Winter?

Aren’t temperatures supposed to get colder and colder and colder until the end of this month, and then get warmer and warmer and warmer? That’s how temperatures generally trend in coastal regions, near large bodies of water, and in western Europe. Not so here in the Hudson Valley and over most of continental North America.
Current winter scene
In my garden, the low was 3 degrees in early December and the high was 59 degrees a couple of weeks ago. Such fluctuations are not that uncommon over much of continental U.S. If you don’t like winter, you welcome those balmy winter days; if you like winter and/or like plants, those balmy days make you shudder.

Plants that can take our cold weather like the weather to stay cold all winter. Each time temperatures warm, especially after we’ve had a spell of cool weather, these plants start to awaken slightly from their winter slumber. The closer to spring and the warmer the weather, the more they awaken. Problem is that the more awake a plant is, the more likely damage, even for a cold-hardy plant, from subsequent frigid weather.

All this makes a good case for growing native plants. They’re more used to our mercurial weather and know better than to let a winter warm spell entice them out of their slumber.

However, many cultivated plants are not native. I like to grow fruits, and any fits of warm weather in weeks to come are going to make me nervous about the apples, plums, hardy kiwis, and pears, all non-native and sometimes awakening early enough to be damaged by subsequent cold.

Blueberries, pawpaws, persimmons, raspberries, and mulberries should be fine. Let’s hope for steadily cold weather and plenty of snow for the rest of winter.

SEED TIME

January 1, 2020/14 Comments/in Flowers, Vegetables/by Lee Reich

Late this Year

This year I’m late, but not too late, with my seed orders. Usually, I get them in by a couple of weeks ago.

The only seeds that I’ll soon be planting are those of lettuce, arugula, mustard, and dwarf pak choy. They’ll fill any bare spaces soon to be opening up where winter greens have been harvested. No rush, though, because I have seeds left over from last and previous years of these vegetables, and they keep well if stored under good conditions.
Greenhouse greens
I’ve usually sowed onion seeds early also, in flats in the greenhouse in order to give plants enough time to become large transplants. Large transplants translates to large plants out in the garden before long days force them to shift from growing leaves to, instead, swelling their bulbs. More leaves before that shift makes for larger bulbs.

Last year, because of poor onion germination in the flats, I ended up getting fresh seeds and sowing them directly in the garden in early spring. Keeping the bed moist promoted quick germination and, by August, the bulbs stood up well, size-wise, to those from seeds sown in the greenhouse in past Februarys.

Seed Longevity

Onion and leek seeds don’t keep very well. Viable seeds are living, albeit dormant, embryonic plants which do not live forever. Conditions that slow biological and chemical reactions, such as low temperature, low humidity, and low oxygen, also slow the aging of seeds.

Seeds differ in how long they remain viable. Except under the very best storage conditions, it’s not worth the risk to sow onion, parsnip, or salsify seeds after they are more than a year old. Two years of sowings can be expected from seed packets of carrot and sweet corn; three years from peas and beans, peppers, radishes, and beets; and four or five years from cabbage, broccoli, Brussels sprouts, cucumbers, melons, and lettuce.
Chart of vegetable seed longevity
Among flower seeds, the shortest-lived are delphinium, aster, candytuft, and phlox. In general, though, most annual flower seeds are good for one to three years, and most perennial flower seeds for two to four years.

In a frugal mood, I might do a germination test for a definitive measure of whether an old seed packet is worth saving. Counting out 10 to 20 seeds from each packet to be tested, I spread them between two moist paper towels on a plate. Another plate inverted over the first plate seals in moisture and the whole setup then goes where the temperature is warm, around 75 degrees.

After one to two weeks, I peel apart the paper towels and count the number of seeds with little white root “tails”. If the percentage is low, the seed packet from which the seeds came gets tossed into the compost pile. (I don’t give them away!). Or, I might use the seeds and adjust their sowing rate accordingly.
Seed testing
No one knows exactly what happens within a seed to make it lose its viability. Besides lack of germination, old seeds undergo a slight change of color, lose their luster, and show decreased resistance to fungal infections. There’s more leakage of substances from dead seeds than from young, fresh seeds, so perhaps aging influences the integrity of the cell membranes. Or, since old seeds are less metabolically active than young seeds, the old seeds leak metabolites that they cannot use.

Finally, Get My Orders In

Today I dug out my shoeboxes of seeds from the unheated workshop and noted what was missing and what was too old.

Needed still are yet undetermined, good varieties of Brussels sprouts, celeriac, semi-hot pepper, and melon. (Any suggestions for good varieties?) Also one or more packets of Bartolo cabbage, Blues Michili cabbage, Shintokiwa cucumber, Golden Bantam 8-row sweet corn, Blacktail Mountain watermelon, Carmen pepper, Mammoth sunflower, and Empress of India nasturtium.
Ordering seeds
And, of course, some tomato varieties need replenishment: Sungold, Anna Russian, Nepal, Carmello, San Marzano, and Amish Paste. They will join Belgian Giant, Pink Brandywine, Paul Robeson, and Blue Beech out in the garden.

A colorful and flavorful growing season is in the offing.
