Of Roses and Berries

Roses Come and Go

I once grew a beautiful, red rose known as Dark Lady. For all her beauty, she was borderline cold-hardy here. Many stems would die back to the graft, and the rootstock, which was cold-hardy, would send up long sprouts. Problem is that rootstocks are good for just that, their roots; their flowers, if allowed to develop, are nothing special.Dark Lady roseAfter a few years of watching the weakened plant recover each season, I made cuttings from some of the stems. The cuttings rooted and the new plants, rather than being grafted, were then growing on their own roots. Even a cold winter wouldn’t kill the roots, living in soil where temperatures are moderated. If the stems died back to ground level, new sprouts would still sport those dark, red blossoms.

I planted my new Dark Lady in a bed on the south side of my house. There, with the brick wall of the house adding a few extra degrees of warmth in winter and spring, Dark Lady might better survive winters coldest nights and get a jump on spring. What’s more, the roots had ample soil to explore rather than being restricted within the narrow, dry bed along my terrace where the mother plant had grown.

The new Dark Lady grew reasonably well in its new bed, but still not as well as I had hoped. Dark Lady is one of the many “English roses” bred by David Austin to have the blowsy look and fragrance of old-fashioned roses coupled with disease resistance and repeat blooming of contemporary roses.

Dark Lady eventually petered out. She’s been superseded by some newer creations from David Austin: L. D. Braithwaite and Golden Celebration are standouts as far a hardiness and beauty, and I expect the same of Dame Judi Dench and Lady of Shalott.

No Sharing of My Highbush Blueberries

Pity the poor birds. My fat, juicy blueberries have been ripening and now there’s a net between them and them.Blueberries galorePutting up the net always brings the words of fruit breeder Dr. Elwyn Meader to mind. When I visited him back in the 1980s, the old New Englander, still active in his retirement and growing about an acre of blueberries, among other crops, recounted in his slow, New Hampshire accent, “It takes a patient man to net an acre of blueberries.” Covering my two plantings encompassing a total of about a thousand square feet always creates a little tension.Netting blueberriesI now feel like a captain setting sail on an old sailing vessel, with all the sails trim and masts set. Except rather than sails and masts, it’s a blueberry net that’s spread tightly over the permanent, 7-foot-high perimeter of locust posts and side walls of anti-bird, plastic mesh. That netting covers 16 bushes within a 25 foot by 25 foot area. Rebar through holes near the tops of the locust posts keeps that side wall mesh taught and 18” high chicken wire along the bottom keeps rabbits, which love to teethe on that plastic mesh, from doing so.Netted blueberriesDon’t worry about the birds. They get their fill of berries elsewhere. I don’t net my lowbush blueberries, nor my mulberries or gumis. Birds don’t usually share the mulberries or gumis with me. This year, for some reason, they are sharing.

Juneberry, a Blueberry Look-alike

Birds also have free access to a blueberry look-alike, juneberries, the plants of which are sometimes called serviceberry, shadbush, and, in the case of one species, saskatoon. The bushes are common in the wild and, because of their pretty flowers, fall color, and neat form, also planted in landscapes.

Juneberries are small, blue, and dead-ringers for blueberries but have a taste all their own: Sweet with the richness of sweet cherries, along with a hint of almond. The birds seem to enjoy them as much as they do blueberries.Juneberries, fruit in handJuneberries are related to apples and pears, not blueberries, and share some of their kin’s pest problems. Especially in my garden. They’re one fruit that didn’t grow well for me so, years ago, I finally dug the plants up.

Neither I nor birds need go far to find wild juneberries or bush or tree types planted for landscaping. They usually bear pretty well because of growing in microclimates more suitable than here on the farmden. In this low-lying valley, the air is too humid, cool, and conducive to disease.

With all the rain this spring, I’ve noticed that the crop on wild and cultivated juneberry plants has been hit hard by rust disease. I hear tell, though, that plants were bearing well at a nearby shopping mall: There, sunlight beating down on nearby concrete and, perhaps, less rust spores wafting about, create a microclimate conducive to good crops of berries.

A New, Old Twist on Strawberries

Strawberries White and Early

Awhile ago I plucked some ripe strawberries and handed them to Rachel for a taste. Her ho-hum reaction told me that I hadn’t picked carefully enough. Yes, the berries were white, but that’s their color when ripe — and also when not ripe.You should be scratching your head by now. Strawberries that are white when ripe? Strawberries perhaps ready for harvest in early May here in the Hudson Valley?

The berries I handed Rachel were alpine strawberries (Fragaria vesca), a different species from our usual garden strawberries (F. X ananassa). They are a kind of “wood strawberry” (often going under their more upscale-sounding French moniker fraises de bois) first encountered about 300 years ago near Grenoble, France. These strawberries are different from garden strawberries in many ways.

For one thing, alpine strawberries are everbearing. They’ll pump out fresh berries as long as given sufficient warmth, water, and nutrients. Mine are bearing now because they’re planted in the ground in my greenhouse. In my pre-greenhouse life they fruited for me in early spring in 3” diameter pots in a sunny window.And no, the plants hadn’t resided in my home and aren’t now in my greenhouse to protect them from winter cold. I wanted an earlier crop. I also grow them outdoors.

'Pineapple Crush' strawberries

‘Pineapple Crush’ strawberries

Alpine strawberry plants are adapted from where winter temperatures plummet below minus 30°F. to regions that hardly experience winter.

These strawberries also part ways with garden strawberries in not producing any runners. I consider this a plus because the worst weeds in a garden strawberry bed are often the plants themselves. As runners strew about and take root, they crowd each other out. The resulting shade and higher humidity make for lower yields and plants more prone to disease.

About 40 years ago, alpine strawberries were hybridized with garden strawberries, with the resulting plants showing typical hybrid vigor with larger fruits and more robust growth. The variety Florika was one of those hybrids, billed as having very good flavor and sufficient vigor and disease resistance so that it can be planted to create a fruiting meadow. Sara and Rebecka are two other hybrids. (Unfortunately, all are red-fruited.)

I’ve never grown any of these hybrids, but will — very soon. Stay tuned.

Small, But Very Easy to Grow

Alpine strawberries are not the strawberries to grow to fill your freezer for winter. Unless you have a lot of patience, that is, because the berries are small, typically about the size of a dime. (The hybrids bear larger fruits, measuring over an inch long.)

You also will rarely, if ever, find the ripe fruits for sale. If they are truly ripe, they are very, very soft, and very, very perishable. The only way to truly experience these berries them is to grow them yourself (easy) and then harvest them dead ripe (pretty easy).

The plants thrive in moderately rich, well-drained soil in full sun or partial shade. In pots, any basic potting mixture will suffice. Potted alpine strawberriesA planting can be started from plants or seeds, the latter started just as are tomatoes. Plants grown from seeds planted in spring will begin bearing their first season.

New plants can also be made by dividing old plants, cutting the crown into pieces along with their attached roots. As with many herbaceous perennials, division or starting new plants is a necessity as plants age and their centers become woody and decrepit.

As far as timely harvest, one way is to follow your nose; the berries are extremely fragrant when ripe. Look at the berries: Ripe ones turn from white to creamy yellow, and their seeds darken to brown. Just the gentlest coaxing removes a ripe fruit from its stem.

Scrumptious!!

A number of gardeners grow alpine strawberries, the red-fruited kinds, which come in a number of varieties. There are, likewise, many varieties of white-fruited alpine strawberries. One year I decided to see just how different these varieties are from one another.Red and white-fruited alpine strawberriesIt turned out that all the red-fruited ones were similar, as were the white-fruited ones. For me, the white ones definitely had better flavor. And the flavor could be enjoyed. Why? Because until they are dead ripe, alpine strawberries have taste somewhat akin to cotton soaked in lemon juice. Problem is that birds are very attracted to, and eat, the red fruits no care as to whether or not the berries are dead ripe.

Birds don’t notice the white fruits when they are ripe so leave them alone for our enjoyment.

A few days ago, when I again saw Rachel, I offered her some more carefully picked fruit. She put them in her mouth, blinked and then open her eyes wide, and exclaimed, “Wow!” That’s the usual reaction to the fruit. Ripe, the white fruits are sweet and richly aromatic with a commingling of scrumptious flavors of strawberry and pineapple.

Grape Futures

My Rationale for Pruning so Late

Today I put the finishing touches on pruning my grapevines. Yes, it’s late: The buds have already swollen and expanded into clusters of small leaves. But there’s “method in my madness,” or, at least, my tardiness.

Vanessa grapes

Vanessa grapes

My vines often experience some winter damage, some varieties — New York Muscat, Reliance, and Vanessa, for instance — more than others. Waiting to prune until I see some green saves me from cutting off too many living canes and saving too many dead canes. In winter it’s not so easy to tell them apart.

So I do mostly rough pruning in winter, lopping back canes that have to go whether they’re living or dead. Canes also need to be shortened, even those that are to be eventually saved.

Which brings me to another reason I left the final pruning until today. Plants generally make their earliest growth in the season starting at the tips of shoots or canes. So when I shortened the remaining canes in winter, I didn’t cut them all the way back to their final length. Then if a late frost nips or kills early growth, it’s no problem. The canes are going to be shortened even further — today — to where buds were not as fully awake and susceptible to cold.

But waiting too, too long to prune can be problematic because those swollen buds flick off their resident canes with very little coaxing. Leave too much to prune this time of year and a lot of buds fly off as pruned canes are pulled down off the plant.

Why Prune? How?

A grapevine bears fruit near the bases of shoots that grow off one-year-old canes. Left to its own devices, the vine might grow 50 feet up into a tree, bear so heavily that it can’t provide sufficient energy to pump optimum flavor into each berry, and become a dark, dank, tangled mess of stems — perfect conditions for fungal diseases.
The goal of various methods of training and pruning grapes are the same: to leave a suitable number of canes conveniently positioned for harvest; to provide buds to grow into new, well-placed shoots for fruiting the following season; and to create a form that allows for good light and air circulation. As might be expected of a plant that’s been cultivated for thousands of years, many ways have been devised for training grapes.

The Four-arm Kniffin System is a kind of “cane pruning,” a traditional method of training in eastern U.S.. For support, a two-wire trellis, with one wire 6 feet and the other wire 3 feet above ground, is needed. The mature plant consists of a trunk with four canes growing from it, two trained in opposite directions along the upper wire and two similarly trained along the lower wire.

Pruning begins as four canes to carry the season’s fruits are selected. These canes should be moderately vigorous and originate close to the trunk and near the wires. With this year’s fruiting canes selected, plans for the following season’s crop are made by cutting back some stems to two buds each; these renewal spurs, as they are called, provide points of origin for new shoots (which will become fruiting canes in a year) near the two wires and on either side of the trunk.

Next, lop away all growth except for the four renewal spurs and the four saved canes. Finally, shorten each of the canes to about 6 ft. in length, leaving about 10 buds per cane (not counting bud clusters near the bases of the canes). This leaves ten times four, or 40, fruiting buds on the plant.

Many Methods with the Same Goal 

At the other extreme in pruning is “spur pruning,” where all that’s left is many 2-bud canes (now called “spurs”) from which grow fruiting shoots. “Head training” would be the most basic spur pruning, with the pruned vine left with nothing more than a trunk capped by a number of spurs.
A spur-pruned vine might instead sport a permanent trunk topped by two arms — permanent arms, called “cordons,” in this case — that run in opposite directions along a trellis wire.

Instead of leaving 4 long canes on which to bear fruit, many short, 2-bud canes are left along the cordons. To get the same number, 40, of fruiting shoots on a spur-pruned vine as on a Kniffen-pruned vine, twenty 2-bud spurs are left. All excess are cut away so that those that remain are 6 to 12 inches from their neighbors. Over time, some spurs will stretch, even after being shorted to 2 buds of one-year-old shoots, further away from the cordon. Lopping these back nearer the cordon puts them back in order.

Where to put all those fruiting shoots growing from the spurs? With “midwire” cordon training, cordons are trained along a wire at 3 foot height, and new shoots are trained upward by weaving them into 3 rows of wires strung at one foot above the cordon wire.
With “high-cordon” training, a trunk rising to about 6 feet is capped by two cordons trained in opposite directions along a wire. Fruiting shoots droop downward.High wire double cordon spur pruned grape
My grapes grow as high cordons, with a wrinkle; their fruiting shoots spread horizontally, rather than droop down. Wooden cross pieces provide this support on my arbor. Although this rigorous pruning puts off how soon the arbor offers relief from early summer sun, the arbor never becomes a tangled mess of stems and disease-ridden berries characteristic of many helter-skelter pruned grape arbors.

The trellis for my other high-cordons have two sets of wires running parallel on either side and one and three feet from the cordon’s wire. These wires provide a ledge on which fruiting shoots can rest, with clusters of grapes dangling just high enough for me to reach for easy harvest.

TIME TRAVEL

18th Century, Here I Come!

Is that me playing the fife? No.

I just returned from time travel one month forward and a couple hundred years backward. Both at the same time! I did this with a trip to Colonial Williamsburg, Virginia, where black locust trees were in full bloom, which is about a month ahead of when they will be blooming up here in New York’s Hudson Valley.

The impetus for this time travel was Colonial Williamsburg’s Annual Garden Symposium, at which I was one of the presenters. (I did presentations on espalier fruit plants and on growing fruits in small gardens.)

Williamsburg is a magical place anytime of year, and especially so, for me, in spring. (I first fell in love with the place on a family trip when I was 7 years old; on subsequent visits, I’ve forgone the three-cornered hat I wore on that first trip.)

The governor's garden

The governor’s garden

The Symposium included tours through many of the colonial gardens, where we  could see, in action, “colonial” gardeners caring for their plants — in many cases using some of the same techniques we use today. Glass cloches, for instance, covered portions of some gardens to hasten warming of the soil for earlier sprouting of seeds. Colonial vegetable gardeners at workFlowering meads of herbs, flowers, and grasses blanketed the ground beneath most of the orchards, providing — probably unknown back in colonial days — forage for beneficial insects to help protect crop plants.

The flowers and vegetables — and fruits in the orchards — are the kinds and varieties grown in colonial times: cardoon, cornflower, chives, cockscomb, pot marigold, nasturtium, hollyhock, Johnny-jump-up, Tennis Ball lettuce, Yellow Crookneck squash, chard, and, of course, corn. Field corn, probably, but also, possibly, sweet corn, which was first given by the Iroquois to settlers in the late 18th century.

Espalier apple trees border vegetable plots

Espalier apple trees border vegetable plots

The gardens in Williamsburg provided and provide more than just sustenance. As in the orchards, flowers mingle with crop plants, in this case, vegetables. Most yards in the reconstructed town are one-half acre, with the land separated into sections with white wood fencing. The whole effect is très charmante. Couple that look with the lack of automobiles within the reconstructed town, and the quiet nights illuminated by the soft glow of fire and candle light (supplemented by electric lights with a candle-like glow), and I think I may want to move back into the 18th century.

Wall Envy

One problem I had with Colonial Williamsburg was wall envy. The church on Duke of Gloucester street, the governor’s mansion, and some other public spaces were enclosed by beautiful brick walls capped with functional and decorative rounded brick.

Most of the homes were covered with white-painted, wooden clapboards. The church and the governor’s mansion were made of brick, which, obviously, harmonized well with their brick walls. Brick wallsMy own home is brick; even a few four-foot-high walls around my vegetable garden and in other areas would improve the general appearance — and provide, warmer microclimates for cold-tender plants or early harvests. Not that the rustic locust fencing and arbors enclosing my vegetable garden look unsightly . . . but I’d like some brick walls.

Incidentally, bricks are made on site at one of the many trades demonstrated within the reconstructed town. I stopped in at the gun shop and stayed soaking up history I never learned in school — how most colonists owned relatively inaccurate muskets which were good enough for hunting and keeping varmints out of gardens, and the real sharpshooters were those with “long rifles,” that is, firearms with rifled barrels that spun their lead shot. But winning a battle wasn’t all about sharpshooters. Long rifles took much longer to reload than muskets, and which side threw the most lead in the air often was what decided who won.

(As part of my immersing myself in 18th century life, I signed up to go to a shooting range to actually fire a flintlock musket. This event, as recorded with 21st century technology, a phone, is documented Musket shooting1, Williamsburg, Musket shooting2, Williamsburg.)

Bricks, rifles, furniture: all these trades are practiced as they would have been in the 18th century. The rifle maker begins his work with nothing more than a block of wood and a block of iron. Four-hundred  hours later, he has in hand a finished rifle. Fabric artisans begin with a sheep or flax seeds and some natural dyes. Cabinetmakers begin with trees or rough cut wood. Their tools are the same as those that to which their 18th century forebears had access.

Plant Envy

In addition to my wall envy, I also experienced the usual plant envy that afflicts me when I go south. Southern magnolia tree reach majestic proportions in Williamsburg; I would like to, but cannot, grow them in this cold climate. Crape myrtle is another, for its flowers and its bark mottled in pastel shades; too cold here for this one also.

I did come upon a number of specimens of fringe tree (Chionanthus spp.), with which I’m only vaguely familiar. The fringes of white blossoms dangling in profusion from the branches made me want to become more familiar, i.e. to plant, this shrubby tree. It turns out that I could — and will — grow fringe tree.Sheep and a barn

Fruit Tree Pruning

The Why, and the Easiest

Following last week’s missive about pruning fruiting shrubs, I now move on to pruning my fruiting trees. Again, this is “dormant pruning.” Yes, even though the trees’ flower buds are about to burst or have already done so, their response will still, for a while longer, be that to dormant pruning.Peach blossomsI mentioned flower buds, so these plants I’m pruning are mature, bearing plants. The objectives and, hence, pruning of a young tree are another ball game. As is renovative pruning, which is the pruning of long-neglected trees.

Most fruit trees need to be pruned (correctly) every year. Annual pruning keeps these trees healthy and keeps fruit within reach. This pruning also promotes year after year of good harvests (some fruit trees gravitate toward alternating years of feast and famine) and — most important — makes for the most luscious fruits.

With that said, as I’ve pointed out previously, a number of fruit trees can get by with little or no pruning, nothing more than thinning out congested branches, cutting back diseased branches to healthy wood, and removing root sprouts.

Among these easiest to prune fruit trees are persimmon, pawpaw, juneberry, jujube, quince, and medlar. (These are some of the uncommonly delectable fruits covered in my book Uncommon Fruits for Every Garden.) Trees such as juneberry and medlar are quite ornamental, so I also lop off or back wayward branches on these trees to keep them looking pretty.

Fruits Borne on New Shoots and/or 1-Year-Stems

The most straightforward approach to pruning those fruit trees that absolutely benefit from annual (correct) pruning is by grouping them according to their fruit-bearing habits.

Figs, for instance, are unique in being able to bear fruits on new, growing shoots.

Figlets on new growth

Figlets on new growth

So the way to prune a fig tree — with caveats — is to lop back branches, which promotes new, fruit-bearing shoots. But not too, too far or the fruit will take too long to begin ripening. I prune branches of my potted or greenhouse Brown Turkey fig trees only as far back as their permanent trunks of a couple of feet or more in length.

Also, not necessarily all the stems should be pruned back on figs, because some varieties also — or only — bear fruit on one-year-old stems. My San Piero fig, for instance. I typically leave some one-year-old stems to bear an early crop, and drastically shorten others for the crop on new, growing shoots, which begins ripening later.

Peach and nectarine trees also bear on one-year-old stems, so are also pruned rather drastically.Peach blossoms I shorten some branches to promote new shoot growth for next year’s harvest. I also remove some branches completely to prevent congestion, allowing branches to bask in sunlight, and breezes to dance among them. When finished, you should be able to throw a cat (figuratively) through the branches without touching them.

Fruits Borne on 1-Year + Older Stems

Fruit trees that bear their fruits on one-year-old as well as on older wood are the next grouping, and include plum, apricot, sweet, and tart cherry. The clusters of flower buds on branches of these trees are known as spurs. (Be careful not to put too much general meaning in “spur” because the word parades under a number of guises in the world of gardening.)

Clusters (spurs) of blossoms on plum

Clusters (spurs) of blossoms on plum

Pruning fruit trees removes some flower buds and potential fruits, which is all for the good because it lets the plant funnel more of its flavor-producing energy into fewer fruits so that those that remain are tastier and larger. Cherries, each of whose small fruits demand little energy, benefit the least of these fruits from such pruning so are the least pruned of the fruits in this category.

Apricot gets the most pruning in this group because its fruit spurs are borne on branches up to 3-years-old. That leaves plums, which get a moderate amount of pruning.

And Even Older Fruit-Bearing Stems

Apples and pears, the final grouping, are the most common tree fruits. Their individual branches each continue to bear flowers and fruits for many years.

Pear sput

Pear spur

Look at an older apple or pear branch and along it you see small, branching stems an inch or less long. These stem clusters are called — and I warned you — “spurs.”

Because their spurs live and bear for a decade or more, apple and pear trees require the least pruning of the fruit trees mentioned.

Then again, spurs do age, eventually becoming overcrowded and decrepit. So I thin out and shorten old spurs so that each has sufficient space and is periodically invigorated with stubby, new growth.

Thinning apple spurs

Thinning apple spurs

Exuberant, vertical shoots, known as watersprouts, often pop up on apple or pear branches. Mostly, they are unwanted because they’re not very fruitful and, left alone, will shade other parts of the tree. I cut these off right to their bases.

Pear watersprouts

Pear watersprouts

Even better is to grab hold of watersprouts when you first notice them growing and rip them off with a quick downward pull. “When noticed,” in contrast to all the pruning I just wrote about, is not during the dormant season.

Pruning Gets Hectic

Easiest to Prune Plants

Most of the pruning I do is “dormant pruning,” that is, pruning while plants are leafless. A few weeks ago, pruning was a relaxed affair with still-cold temperatures keeping the buds only slowly swelling in anticipation of upcoming growth. Then a few warm days kicked them into gear, making pruning more hectic.

Berries of July

Berries, later

Hecticness is little problem with those plants that are the easiest to prune because the work can be quick; other plants require my standing back with arms folded for some study before every few cuts.

Here on my farmden, easiest to prune plants include mature ornamental trees, shrubs, and vines, and even some fruits. Those fruits are American persimmon, pawpaw, and mulberry. They’re so easy because they can get by with little or no pruning.

Mostly what I do with the three fruit trees, every year or so, is to take a lopper or a saw and hack back . . . whoops, I mean “prune” . . . a tall limb back to a weaker growing, usually more horizontal, side branch. That’s to keep fruit within safe reach or not falling so far of its own accord that it splatters upon the ground. It also doesn’t leave a tree looking like a victim; done correctly and you hardly know that steel has been taken to the tree.

Easy, but Need Annual Pruning

Then there are easy-to-prune plants that do need annual pruning, but pruning them is as easy as following a recipe. Brambles — blackberries and raspberries — are counted in here. They all have perennial roots but their canes are biennial. That is, canes just grow the first year, then fruit and then die their second year.

The first step in pruning these plants, then, is to get down near ground level and cut all the two-year-old canes to the ground. These canes broadcast their age with peeling bark and an old and dead, or dying, appearance.

Gardeners telling tell me about their raspberry or blackberry patches make me cringe. “Patch” does conjure up an image of a cozy, cottage-y planting, but isn’t the way to grow these fruits if you want to make picking easy and limit disease problems. All of which leads to step two of this recipe.

Red or yellow raspberries spread to create a patch by sending up shoots via underground runners; black raspberries and blackberries do so by arching their long canes to the ground where they take root and make new plants. Too many new plants, in either case.

Red raspberry bed, pruned

Red raspberry bed, pruned

So I limit my red or yellow raspberries to a swath only a foot wide, and then within that swath remove enough plants so those that remain are a few inches apart.

With black raspberries and blackberries, I remove any plants closer than 3 to 5 feet apart (depending on their vigor) and then thin out remaining canes in each remaining clump to the fattest and healthiest-looking half-dozen.

One more step for these berries is to shorten red or yellow canes enough to keep them from flopping around. How much depends on how tall they are and how they are trellised, if at all. Black raspberries and blackberries fruit on side shoots; these need to be shortened to about 18 inches long.

(So-called everbearing — aka “fallbearing” — red or yellow raspberries can be pruned as described above. Or, just lop the whole planting to the ground late each fall, sacrificing midsummer harvest but still offering late summer and early fall berries.)

Also Easy

Two more fruits also fall into this easy-to-prune category. 

Lowbush blueberries, like brambles, bear on two-year-old (and, to a lesser extent, three-year-old stems). But they grow too many stems to selectively prune them.

So I take my hedge trimmer and every other year, or every third year, cut all stems to the ground.

Shearing lowbush blueberries

There’s no crop the year they are pruned but dividing a planting in halves or thirds and pruning a different half or third every year circumvents that drawback.

Lowbush blueberries, flower buds

Lowbush blueberries, flower buds

Blackcurrants bear in a similar manner to lowbush blueberries but their stems are few enough for selective pruning. I cut to the ground any 3-year-old stems as well as anything more than the best half-dozen 1-year-old stems.

Blackcurrant, before & after pruning

Just a Wee Bit More Difficult

From here, I move on to shrubs — only slightly more difficult to prune — that bear fruit on older wood, which determines which stems I cut out. 

Most gooseberries and redcurrants, for example, bear best on stems 2 and 3 years old. So the strategy here is the same as for brambles, except that the stems that I cut away are those that are 4-years-old. After that I remove excess new stems arising from ground level. When pruning is finished, the shrubs are left with about six each of one-, two-, and three-year-old stems.

Pruning blueberry bushes also follows the same strategy, except that since the bushes bear well on stems up to six-years-old, I prune away stems older than this and cut to the ground all except the healthiest 4 new stems.

Now on to the fruit trees. Wait, I can’t do it now! I’ve got to run outside, grab my hand shears, lopper, and pocket saw, and do some pruning. Stay tuned next week for fruit tree pruning.

Redcurrant espalier. How to prune it? Some other time.

A Farmdener, That’s Me

A New Word is Introduced

I’d like to introduce the words farmden and farmdener into the English language. I wonder if there are any other farmdeners out there.

What is a farmden? It’s more than a garden, less than a farm. That’s my definition, but it also could be described as a site with more plants and/or land than one person can care for sanely. A gardener and garden gone wild, out of control.Farmden, aerial view

You might sense that I speak from personal experience. I am. My garden started innocently enough: A 30 by 40 foot patch of vegetables, a few apple trees, some flowers, and lawn. That was decades years ago, and in the intervening period, the lawn has grown smaller, the vegetable garden has doubled in size, and the fruit plantings have gone over the top.

Originally, I had less than acreage – 72 hundredths of an acre to be exact. But over the course of 15 years, I did manage to put my fingers onto almost every square foot of that non-acre. Squeezed into that area were 40 varieties of gooseberries, a dozen varieties of apples, a half dozen varieties of grapes, red currants, white currants, black currants, raspberries, mulberries: you get the picture. All that, in addition to my vegetables, flowers, and some shrubbery. But I was still not a farmdener, and my property was not a farmden.

Evolution of My Farmden

The transition from garden to farmden occurred with the purchase of a fertile acre-and-a-half field bordering the south boundary of my property.

With that purchase, I expanded my plantings, rationalizing that because I write about gardening (for magazines, for Associated Press, and for this blog) and host workshops here, I should test and grow a lot of what I write and talk about. So instead of 2 hardy kiwifruit vines such as any normal gardener might grow, I planted 20 vines of a few species and varieties. Instead of 2 pawpaw trees, à la normal gardener, I planted 20 pawpaw trees of  few varieties.

Pawpaws, blackcurrants, and hardy kiwis

Pawpaws, blackcurrants, and hardy kiwis

And how about another dozen apple trees? And chestnuts, filberts, pine nuts (Pinus koreansis is hardy here in New York’s Hudson Valley). Again, you get the picture.

But no, I wasn’t finished. There was always one more plant needing a home, one more piece of ground hungry for a plant. Why not create another vegetable garden; after all, I had just gotten married, and that made another mouth to feed. Why buy vegetables when you have enough land to grow them?Vegetable garden And what about winter? A greenhouse full of salad and cooking greens solved that problem, in addition to providing figs in summer and early and late season cucumbers.

Greenhouse fig

I like crown imperial (Fritillaria imperialis) flowers and learned the quirks of propagating them – pack pieces of bulb scales in moist potting soil and subject them to a few months of warm temperatures, then a few weeks of cool temperatures, pot up, plant out. Soon I had not a crown imperial or two such as you might find in most gardens, but dozens of them, and more still coming on.Crown imperial

You might imagine that, despite my plantings, my lawn still grew bigger with that increased acreage. Not so. Most of the acre and a half, except what was devoted to new plantings, became a hayfield that I mowed and helped feed my compost pile. A bit of rationality prompted me to graduate from scything to a small farm tractor for brush hogging that field. (Tennis elbow, the result of excessive scything, also helped with that decision. But I still use the scythe, a high quality Austrian style scythe, to mow parts of the field.)

Present and Future

What I now had – and have – is a farmden. And I am a farmdener. A farmden is not something from which you can earn a living, although I have sold some excess pawpaws, American persimmons, and hardy kiwifruits, mostly for test marketing in my efforts to see whether these fruits are worth promoting for small farms. (They are; flavor sells.)

And my farmden is a great venue for workshops, as long as I point out that participants should pay attention to my plants, not the number of them, because my property is obviously the handiwork of a crazed gardener (or a sane farmdener?). “Don’t try this at home,” I tell participants right off the bat.Farmden view

I do occasionally still garden. Right next to my terrace is a bed with tree peonies, potentiillas, clove currants, and Signet marigolds, all well-contained by the bricks of the terrace on one side and a low, moss-covered hypertufa wall on the other side. The bed is close to the house and the bed is small. Yesterday I noticed weeds starting to overstep their limit in the bed. I crouched down, started at one side of the bed, and gave it a thorough weeding, literally getting my hands on every square inch of soil. It was fun and it was quick.

Most of my time, though, is spent farmdening. It’s very satisfying, even if it does get crazy sometimes, and it yields a cornucopia of very tasty and healthful fruits and vegetables, many of them planted with an eye to beauty as well as function.

I have vowed not to plant anything more in the hayfield, in large part because it’s so pretty, the soft violet hue from midsummer’s monarda flowers grading over into a golden glow from late summer’s goldenrods. I also promised my daughter, when she was young and enthralled with Laura Ingalls Wilder, that we would leave most of the field as “prairie.” (Now over 30 years old, my daughter no longer yearns for prairies, but I’m keeping my promise.)South field

I have taken some of the edge off the transition from gardening to farmdening with some help here on the farmden from an occasional helper. Still, I am planning to keep the “den” in farmden.

Down in Dixie

Green, Green, Green, and Flowers!

After delivering a couple of lectures about gardening in North Carolina, I set off on a very short, whirlwind tour of the southeast, specifically North Carolina and Georgia, and ending with a stay in Charleston. How different from my spot here in New York’s Hudson Valley!

For all Charleston’s uniqueness, three characteristics jumped out. It being early March and my coming an achromatic landscape of snow, sleeping plant life, and cold, I was immediately struck by the abundance of greenery. Not the tired greenery of many evergreens here in the north, but vibrant, awake greenery in a variety of shapes, textures, and sizes.

Camellia blossoming in Charleston

Included in all that Charlestonian greenery were fronds of palm trees — saw palmetto and sabal palmetto — fanning out above jagged trunks. Those palms were a reminder that I was now in a subtropical rather than temperate climate. Not that the weather helped make the point; some days were in the high 40s and one night temperatures were predicted to dip near freezing.

March notwithstanding, Charleston had no dearth of flowers. Camellia blossoms stared out from a backdrop of their verdant foliage. Camellia is one of my favorite plants. I tried to grow one of the hardier new varieties of camellia a few years ago, offering it some cold protection by planting it near my home; it died its first winter. I wonder if southerners become blasé about these blossoms; camellias were growing everywhere, and in bloom.

The white blossoms of sweet osmanthus belied their diminutive size with the strength with which they perfumed the air. The fragrance was fruity, apricot.

Very different was another fragrance, this one wafting from clusters of trumpet-shaped blossoms dangling from the bare stems of edgworthia, also known as paperbush. That’s another plant that won’t grow this far north but no matter. I wavered between enjoying and not enjoying its resinous aroma.

If only gardenias — another plant growing outdoors in the southeast but not hardy here in the North— had been in bloom, the olfactory part of my trip would have been complete. All I could do was marvel at what it would be like if I could have a dooryard shrub of gardenia. I might be on the verge of passing out as I hyperventilated through the bloom season.

Oranges? No. ‘Quats? Yes

Two interesting fruits turned up here and there.

One was loquat, an odd relative of apple and pear. The leaves are large, dark green, and evergreen with a matte finish, all of which makes an appearance that is subtropical, which the plant is. 

Most odd is loquat’s bearing habit. It flowers in autumn and ripens its fruit in spring or early summer. I once bought one at a fruit stand in Paris. Its flavor was unimpressive, but that’s true of many commercially marketed fruits. Loquats generally receive high praise for flavor. If I ever get to taste a good one, I might grow the plant in the loquat-perfect environment of my greenhouse.

The other fruit was citrus, two fruits, actually, and also “-quats” but not at all related to kumquat. They were kumquat and citrangequate. It just didn’t seem like citrus could be hardy that far north (except for the super-cold-hardy but hardly edible trifoliate orange, which I have growing outdoors).Kumquats in Charleston But winter low temperatures in Charleston rarely dip even to freezing but kumquat trees are hardy into the ‘teens. A few citrangequats — trigeneric hybids of kumquat, trifoliate orange, and sweet orange — that I stole from a tree proved to be tasty with sweet, edible rind enclosing a pleasingly tart interior.

Southern Faves

Three of my favorite plants that I cannot grow were present in abundance. I already mentioned camellia. Another is southern magnolia, a stately tree that differs from northern magnolia in having very large, leathery, evergreen leaves that look somewhat like the rubber trees that are common houseplants.

It was too early for the large, white, fragrant blossoms to appear but I would grow the tree for the leaves alone, if I could. It’s almost hardy here; I’ve seen trees in northern New Jersey.

Another favorite is a deciduous plant also almost cold-hardy here: crape myrtle. The plants are decked with bright flowers in various shades of red all summer, but are bare of leaves or flowers in winter, even in South Carolina. No matter, crape myrtle has a mottled, shedding bark that puts on a good show when its flowers are offstage.Crape myrtle bark

And A Dark Cloud

A dark cloud that hangs over Charleston is its role in the slave trade. About 40% of all slaves entering America entered through Charleston. And it’s not just a statistic like this or a visit to the Slave Museum, site of one of Charleston’s many slave auctions, that recalls the horrors of human bondage. I couldn’t help, when visiting the plantations in and near Charleston, constantly reminding myself that they were only possible with the labor of enslaved humans. Reminders are everywhere; even the bricks of the buildings right in town were hand made by slaves.

Many of the slaves auctioned off in Charleston were separated from their families and transported to other sites throughout the colonies, making all the colonies and then states culpable. 

 

Future Hopes

 Totipotentiality (Is This a Word?)

I was so excited one day a few years back to receive a box full of leafless sticks by mail. The exciting thing about those sticks was that each one of them could grow into a whole new plant from whose branches would eventually hang luscious apples and grapes.Grape cuttings

  And how did I know the fruits will be luscious? Because a year prior I was at an experimental orchard getting fruit photos for a book I was working on. Of course, I couldn’t help but also taste the fruits, and that’s why Chestnut Crab, Honeygold, Mollie’s Delicious, and King of the Pippins joined the two dozen or so other varieties of apples I already grew. Cayuga White, Bertille Seyve 2758, Steuben, Lakemont, Wapanuka, Himrod, Romulus, and Venus joined my grapes.

  It was “totipotence” – of the plants, not me – that allowed me to unlock potential treasures within those mailed sticks. Within a plant, every cell except for reproductive cells has the potential to become a root, a shoot, a flower, a thorn, a fruit, or any other part of a plant. For that matter, the same is true for humans and other animals. All that’s needed are the right conditions to get the various parts to grow – and there’s the rub.

  A little art and science puts totipotence to work. In the case of the apples, I grafted those stems onto my existing trees or onto small rootstocks. Existing trees or rootstocks provide nothing more than roots to nourish shoots that will eventually sprout from the sticks. The plant beyond the graft remains genetically that of whatever variety is grafted upon the rootstock. Bark graftGrape sticks got plunged into the ground where they grew their own roots, shoots, and everything else. Apples aren’t so amenable to growing their own roots.

  I generally wait to graft or set cuttings until early spring. Warmth awakens those sticks. Until then, they’re kept cool and dormant.

  I planned on tasting the first fruits of my labors within about 3 years.

Out With the New, In With the Newer

None of those varieties I received as leafless sticks are still with me.

Because of pests, apples are especially problematic to grow here so I subsequently narrowed down my apple holdings to trees of my few very favorite varieties: Macoun, Liberty, Ashmeads Kernel, Pitmaston Pineapple, and Hudson’s Golden Gem.Cleft graft one year old

Except for Wapanuka, the grapes never tasted as good here as they did at that experimental orchard. Is it because of terroir? Was it the setting that influenced my tastebuds? Anyway, they’ve been replaced by other “sticks” — Somerset Seedless, Glenora, and Vanessa — that now bear fruit in the rows with my older, established vines..

Murphy’s Law, Amendments

Although I have gardened for decades, I still consider myself a relative newbie to greenhouse gardening. Sure, I’ve dabbled in various greenhouses over the years but I’ve only experienced the intimate vagaries of my own greenhouse for the last 18 years. It took time for it to finally dawn on me that Murphy’s Law – “Anything that can go wrong, will go wrong” – also applies in the greenhouse. In retrospect, why wouldn’t it?Greenhouse, March 1st

  I’ve had my brushes with the law. For instance, one winter evening a few years ago when I went to pick some lettuce for a salad; methinks, “Hmmm, quite nippy in here.” But then, except from when sunlight is beaming through the plastic covering, it’s always nippy in there in winter. Salad greens, kale, chard, and celery thrive in those cool temperatures, which dip into the mid-30s before the propane heater kicks on. (The in-ground figs stay dormant and leafless.)

  Still, temperatures felt nippier than normal so I checked the thermometer to confirm and, yes, it was getting down to the high 20s. I then checked the propane heater; it ignored me as I twisted the dial on the thermostat clockwise.

  Right then and there, I proposed an amendment to Murphy’s Law: “Anything that can go wrong, will go wrong — at the worst possible time!” Temperatures the night before had plummeted below zero. No wonder a water line had burst that morning. I had assumed that frigid temperatures had made only that corner of the greenhouse too cold. Fortunately, after a lot of nail biting, the gas man and I determined that the pilot light had blown out in the heater. Most plants survived the cold.

  One event does not a Law make. Thinking back to another Murphy event, I remember an even more serious freeze in the greenhouse. One day everything looked verdant; the next day mush. (The gas company had forgotten to re-fill the propane tank.) After that event, I rigged up a backup electric heater, just in case temperatures dropped below freezing.

  Perhaps yet another Murphy’s Law Amendment is needed. On the night of a more recent freeze, the electric heater was, of course, hooked up. Except it wasn’t poised for warmth. The thermostat was directing it to wake up, but I had forgotten to flip the heater’s “on-off” switch to “on.” My bad.

  Live and learn: The sun is now setting, the mercury is now plummeting, but no fear of high winds blowing out the pilot light again. I subsequently upgraded the heater for a pilot light-less one. But when I go out to pick some lettuce, celery, and parsley, I will: Check propane heater, check electric heater, check that the water line is off. And remember to latch the door closed on my way out — really!

Get Crackin’

Cured!

It’s finally time to get crackin’. Literally. Black walnuts are ready for shelling.
This nutty story goes back to early this past autumn as black walnut trees were shedding their nuts. The nuts fall in their husks, the whole package looking like green tennis balls. Lots of people curse the trees for littering lawns, sidewalks, and driveways. We, on the other hand, praise and collect the nuts.Cracked and whole black walnuts

The first step to the present day crackin’ was husking the nuts. The soft, fleshy covering is easy to twist off the enclosed, hard-shelled nut. But we’ve also tried many methods to speed up the process, from spreading the dropped fruit in the driveway and driving over them to pounding them through a 1-1/2” hole in a thick piece of plywood to running them through a suitably modified old-fashioned corn-sheller.Black walnuts in husksVarious black walnut hullers

There’s no way around it: Husking black walnuts is a tedious job. And messy, because the soft flesh readily releases a juice which stains everything a deep brown color.
A friend recently told me of some novice black walnut enthusiasts that husked the walnuts bare handed, assuming the stain would wash off when they were finished. Not so. My wife Deb, who husks our black walnuts, chooses to sit herself down on a stool, don rubber gloves, and twist off the hulls, coaxing firm ones off with an initial tap with a light sledge hammer.

(The stain, which is colorfast and resistant to ultraviolet rays, is very easy to extract from the hulls for ink, for dyeing textiles, and staining wood. Just mix the hulls or unhulled nuts with water and boil for awhile or let sit a longer while. Strain and you’re good to go.)

In not too long, we had a number of 5 gallon bucketfuls of hulled nuts — a slimy, ugly mess from bits of hull still attached to the nuts and from the myriad white maggots crawling.

Now it was my turn — to clean up the nuts. I loaded all the nuts into shallow harvest boxes that had plenty of large holes for air or water and drove over to a nearby car wash. After suiting up in an old pair of rain pants, a rain jacket, rubber gloves, and a face shield, and spreading out the boxes on the ground in the car wash, I gave them a thorough, water-only cleaning.Husked nuts

I then spread the boxes out in the sun for a couple of days to dry out the surface of the nuts. Squirrels would be a serious threat but I spread the boxes on our south-facing deck where our two dogs also spend much of the day unknowingly guarding the nuts. Each night, or if any rain was predicted, I stacked and covered the boxes.
After the nuts were sufficiently dry, I stacked the trays in the barn where our cat is the squirrel deterrent.

Then the nuts needed to be cured, which involves nothing more than leaving them alone in a cool, dry, squirrel-fee area. And that brings us up to the present day.

A Tough Nut

Black walnut is a hard nut to crack. No run-of-the-mill nutcracker is up to the job. The usual tool, which is effective, is a hammer against the nut resting on an anvil or concrete. Used with care, a vise might do the job.

Two problems: With the hammer, hitting your finger occasionally as you hold the nut is inevitable. You could, I guess, hold the nut in a pliers. With either method, you have to use just the right amount of force to crack the shell sufficiently in order to extract the nutmeats in reasonable sized pieces without crushing everything too, too small.
The hands-down best job for cracking black walnuts is, in my opinion, the “Master Nut Cracker” (http://www.masternutcracker.com). It’s expensive but well worth the money for the speed with which the nuts can be cracked and the large nutmeats that result from efficient cracking. Besides which, it’s a very well-made tool with a very ingenious design.

Once nuts are cracked, nutmeats still occasionally need further coaxing to free them from the shell. A useful tool that I use that almost everyone has is a type of wire cutter sometimes called a diagonal cutting plier. The right squeeze in the right place, the result of observation and practice, yields large nutmeats that pop right out.Prying out nuts with pliers

But Is It For You?

Black walnuts have a strong flavor that, like dark beer and okra, is loved by some but not enjoyed by everyone. But there’s no reason why everyone should like everything. Leave that goal to MacDonald’s. As L. H. Bailey, a doyen of horticulture, wrote back in 1922 (about apples), “Why do we need so many kinds of apples? Because there are so many kinds of folks. A person has a right to gratify his legitimate tastes.”

Black walnut is one of my favorite nuts. And, the trees and nuts abound around here, and elsewhere, free for the taking.black walnuts in jar
