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

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

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

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.

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.

SOIL MATTERS

Plastic on My Bed?!

You’d be surprised if you looked out on my vegetable garden today. Black plastic covers three beds. Black plastic which, for years, I’ve railed against for depriving a soil of oxygen, for its ugliness, for — in contrast to organic mulches — its doing nothing to increase soil humus, and for its clogging landfills.Tarped soilActually, that insidious blackness covering my beds is black vinyl. But that’s beside the point. Its purpose, like the black plastic against which I’ve railed, is to kill weeds. Not that my garden has many weeds. But this time of year, in some beds, a few more sprout than I’d like to see.

The extra warmth beneath that black vinyl will help those weeds get growing. Except that there’s no light coming through the vinyl, so most weeds will expend their energy reserves and die. And this should not take long, depending on the weather only a couple of weeks or so.

So, first of all, I’m covering the ground for a very limited amount of time.

Furthermore, that the black vinyl is not manufactured specifically for agriculture. It’s recycled billboard signs, available on line from www.billboardtarps.com and other sources.  For larger scale use, farmers use the material sold for covering silage. 

Old billboard signs or silage covers also improve on black plastic mulch because they are tough. Each time they’ve done their job they can be folded up for storage for future use to be used over and over.

Heavenly Soil

Decades ago, I made a dramatic career shift, veering away from chemistry and diving into agriculture. In addition to commencing graduate studies in soil science and horticulture, I rounded out my education by actually gardening, reading a lot about gardening, and visiting knowledgable gardeners and farmers, including well-known gardener (and better known political and social scientist) of the day, Scott Nearing.
Scott Nearing's gardenI had just dug my first garden which had a clay soil that turned rock hard as it dried, so I was especially awed, inspired, and admittedly jealous of the soft, crumbly ground in Scott’s garden. What a surprise when someone who had worked with Scott for a long period told me how tough and lean his soil had been when he started the garden. A number of giant compost piles were testimonial to what it takes to improve a soil.

I thought of Scott and his soil as I was planting peas a few days ago. My chocolate-colored soil was so pleasantly soft and moist that I could have made a furrow with just by running my hand along the ground. For a long time I’ve appreciated the fact that the soil in my vegetable garden is as welcoming to seeds and transplants as was Scott’s.

And my dozen or so compost piles, inspired by Scott’s, are testimonial to those efforts. My compost pilesThe soil in my permanent vegetable beds is never turned over with a rototiller or garden fork; instead, every year a layer of compost an inch or so deep is lathered atop each bed, and no one ever sets foot in a bed. That inch of compost snuffs out small weeds, protects the soil surface from washing away, and provides food myriad beneficial microbes (and, in turn, for the vegetable plants).

All sorts of what I consider gimmicky practices attract gardeners and farmers each year: aerated compost teas, biochar, nutrient density farming, fertilization with rock dust, etc. Yet one of the surest ways to improve any soil is with copious amount of organic materials such as, besides compost, animal manures, wood chips, leaves, and other living or were once-living substances. A pitchfork is a very important tool in my garden.

Uh Oh, A Soil Problem

Not all is copacetic here on the farmden.

I make my own potting soil for growing seedlings and larger potted plants. It’s a traditional mix in that it used some real soil. Just about all commercial mixes lack real soil because it’s hard to maintain a sufficient supply that is consistent in its characteristics.

Early this spring, as usual, I sifted together my mix of equal parts compost, peat moss, perlite, and garden soil. This year, NOT as usual, germination of seeds and seedling growth has been very poor. Just today, I re-sowed all my tomato seeds in a freshly made mix from which I excluded soil.

I’m not 100 percent sure that the soil in the mix is the culprit, but it is suspect. I have a small pile of miscellaneous soil that I keep for potting mixes and other uses. Good and bad seedlingsRecent additions to that pile were an old soil pile from a local horse farm and soil from a hole I was digging to create a small duck pond. The latter was poorly aerated subsoil.

Seedlings are growing well in my new mix composed only of compost, peat moss, and perlite.

A Podcast and a Workshop

I was recently on Joe Lamp’l’s gardening podcast talking about “uncommon fruit.” They’re worth growing because they’re easy, they’re ornaments, and, with few or no pest problems, they’re easy. And they have excellent and unique flavors. Listen to the podcast here.

Also, I’m hosting a pruning workshop at my New Paltz, NY farmden:Pruning workshop announcement

The Season Begins

One More Thing? Ha!

I have one more important task to do before planting any vegetables this spring, and that is the annual mapping out of the garden, something I generally put off as long as possible.

In theory, mapping out my garden should be easy. I “rotate” what I plant in each bed so that no vegetable, or any of its relatives, grows in a given bed more frequently than every 3 years. Garden planning on paperIn practice, I mostly pay attention to rotation of plants most susceptible to diseases, which are cabbage and its kin (all in the Brassicaceae), cucumber and its kin (Cucurbitaceae), tomato and its kin (Solanaceae), beans and peas (Fabaceae), and corn (sweet or pop, in the Gramineae).

Crop rotation prevents buildup of disease pests that overwinter in the ground; removing host plants eventually starves them out. (Insect pest are more mobile, so crop rotation has less impact except in very large plantings.) So one year a bed might be home to cucumbers, melons or squashes. The next year that bed might host cabbage, broccoli, kale, Brussels sprouts, or cauliflower. Then tomatoes, peppers, potatoes, or eggplants. And finally, the fourth year, back to cucumbers. Simple enough.

It would also be nice to rotate carrots and other root vegetables with leafy vegetables, such as lettuce, and fruiting vegetables, such as tomatoes. My garden's bedsRoot, leafy, and fruiting vegetables have somewhat different nutrient needs, so in the ideal garden these crops are rotated to make best use of soil nutrients.

And I do like to get the most out of my garden and confuse potential insect pests by grouping different kinds of plants within a bed.

Are you beginning to understand why I put off committing my garden plan to paper each spring?

Pea Problem(s)

Peas present one more wrinkle in my vegetable garden planning. A few years ago they stopped bearing well, collapsing with yellowing foliage not long after they bore their first pods.

Further investigation has narrowed the problem to – probably – one of two diseases: fusarium or aphanomyces. Both, unfortunately, are long-lived in the soil so that a 3 year rotation does nothing to keep them in check.

Fortunately, I have two vegetable gardens. So, for the past few years I have banned peas from my north garden, planting them only in my south garden, in which they do get rotated. After a few more years, I’ll move the pea show to my north garden and leave my south garden pea-less. I’ve also been planting the varieties Green Arrow and Little Marvel, both of which are resistant to fusarium, at least.

Unfortunately, the problem is more likely aphanomyces, for which resistant varieties do not exist. Aphanomyces is a water mold, so thrives under wet conditions. So my tack will also be to keep any peas planted in my vegetable garden on the dry side, not even turning on the drip irrigation in those beds.

I’ll also be checking the plants more closely for symptoms. Plants infected by fusarium have a red discoloration to their roots. Fusarium-infected pea rootsPlants infected by aphanomyces have fewer branch roots and what roots there are lack the plump, white appearance of healthy roots.Pea roots with aphanomycesPea roots with aphanomyces

Pea Solution?

I’m also testing out root drenches with compost tea for my peas.

Yes, yes, I know I have dissed compost tea in the past. Mostly, its benefits, if any, have been overstated. But compost microbes have more chance of surviving in the dark, moist, nutrient-rich environment of the soil than on a leaf, where the stuff is often sprayed. I’m drenching the soil with the tea, not just giving the surface a spray, as usually recommended, so a lot more bacteria, fungi and friends are finding their way down there.

I see no reason (and research does not support) of going to the trouble of making the usual compost tea, which is aerated and might be fortified with such things as molasses. Compost tea, quick mixMy tea is nothing more than the liquid strained from compost soaked in water, then applied with a watering can at the base of the pea plants.

I’ve done this for a couple of seasons but have nothing definite to report yet. The hard part is sacrificing a bed as a control. Perhaps this year.

Increasing My Hyacinthal Holdings

Hyacinth City

I’ve admitted this before; here’s more evidence of my addiction — to propagating plants. I currently have a seed flat that’s only 4 by 6 inches in size and is home to about 50 hyacinth plants. Obviously, the plants are small. But small and sturdy.

The genesis of all these plants goes back a couple of years when I needed photos for my book The Ever Curious Gardener: Using a Little Natural Science for a Much Better Garden. For the chapter on some aspects of the science of plant propagation and the practical application of that science, I made photos of some methods of multiplying hyacinth bulbs. Here’s an excerpt of that section:
Hyacinth growing bulblets“Knowing what a bulb really is makes it easier to understand how they can multiply so prolifically that their flowering suffers, and how to get them to multiply for our benefit. Dig up a tulip or daffodil and slice it through the middle from the tip to the base. What you see is a series of fleshy scales, which are modified leaves, attached at their bases to a basal plate, off of which grow roots—just like an onion (but, in the case of daffodil, poisonous!). The scales store food for the bulb while it is dormant.

That bottom plate is the actual stem of the plant, a stem that has been telescoped down so that it’s only about a half-inch long. Those fleshy scales are what store food for the bulb, and, depending on the kind of bulb, are nothing more than modified leaves or the thickened bases of leaves.
Bulb cross-section diagramLook at where the leaves meet the stems of a tomato vine, a maple tree—any plant, in fact—and you will notice that a bud develops just above that meeting point. Buds likewise develop in a bulb where each fleshy scale meets the stem, which is that bottom plate. On a tomato vine, buds can grow to become shoots; on a bulb, buds can grow to become small bulbs, called bulblets. In time, a bulblet graduates to become a full-fledged bulb that is large enough to flower.”

Natural Increase

“Let’s see just how the big three flowering bulbs—tulips, daffodils, and hyacinths—grow. With tulips, the main bulb, the one that flowers, disintegrates right after flowering and is replaced by a cluster of new bulblets or bulbs. The mother bulb of a daffodil continues to grow after flowering, at the same time producing offsets of bulbs or bulblets which may remain attached to the mother bulb. Hyacinths grow the same way as daffodils, except for being much more reluctant to make babies.

All those bulblets and bulbs can, in time, crowd each other for light, food, and water, so flowering suffers. When my daffodils, tulips, or hyacinths seem to be making too many leaves and too few flowers, I know it’s time to dig them up and separate all the bulbs and bulblets. The best time for this operation is just as the foliage is dying back in spring or early summer because after that plants are out of sight until the following spring. Replanting can be done immediately or delayed until autumn.”

The Scoop on Propagating Bulbs

“Knowing something about bulb structure also gives me inside information on how to multiply my holdings faster, perhaps to make enough plants for a whole field or a giant flower bed. Merely digging up and planting offsets is one way of doing this. Also, knowing that the bottom plate is a stem and that the offsets come from side buds lets me coax those side buds to grow just as can be done with any other stem.

Pinching out the growing tip of any stem makes side buds grow. One way you get rid of, or ‘pinch out,’ the growing tip of a bulb is to turn the bulb upside down, then scoop out the center of the bottom plate with a spoon or knife. Bulb scoopingAnother way is to score the bottom plate with a knife into 6 pie shaped wedges, making each score cut deep enough to hit that growing point. Bulb scoringAfter scoring or scooping, set the bulb in a warm place in dry sand or soil for planting outdoors in a nursery bed in autumn.Hyacinth dormant bulbletsAfter a year, as many as 60 bulblets might be sprouting from the base of each scooped or scored bulb. Each bulblet does take 4 or 5 years to reach flowering size, but no matter. To quote an old Chinese saying: ‘The longest journey begins with the first step.’”

My little hyacinth bulblets are now in their second season of growth. I’ll keep them growing strongly until their leaves yellow as they go naturally dormant, probably late this spring. Come fall, I’ll dig them all out, separate them, and then plant them out in a nursery bed or else in their permanent homes. I expect aromatic bliss in a couple of years.

And, On Another Note

I was recently a guest on Susan Poizner’s radio show/podcast where we talked about growing uncommon fruits, here at my farmden and in general. Hear it at https://orchardpeople.com/growing-uncommon-fruits/

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

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. 

 

Volunteers and Clementine Boxes

Celery Volunteers for Me

I’m always on the lookout for volunteers in my garden, whether they’re people, fungi, plants, or any other organisms. The relationship is usually symbiotic. Human volunteers gain some knowledge and experience; I get some help in my ever-growing farmden. Fungal volunteers work with my plants, drinking in some of the sugars and other goodies plants produce. In return, the fungi protect plants agains certain pests and, in the case of mycorrhizal fungi, fungal threads ramifying through the soil act like extensions of plants’ roots so plants can absorb more nutrients.

  But what do plant volunteers get out of our arrangement? Plant volunteers usually arrive in droves so only some can stay. Those that stay get to enjoy especially good growing conditions.

Which brings me to celery. Volunteer celery plantsFor the past few years, I’ve allowed celery in the greenhouse to go to seed each fall. The seeds drop and, within a few months, sprout to furnish plenty of seedlings for early summer celery in the greenhouse and later celery out in the garden. All of which is most welcome because celery seedlings are very slow to germinate and grow. Before celery volunteered around here, I had to sow seeds in early February in seed flats, keep the flats warm and moist until the seeds sprouted, transplant the sprouts into individual cells in another flat, and finally transplant the seedlings, after about 10 weeks of care, out into their permanent homes.

  Robust celery seedlings have sprouted and are now growing in a greenhouse bed and in the paths near near that bed, all without any help at all from me. I just lifted clumps of them, separated the seedlings carefully to minimize root disturbance, and “plugged” them back into the ground 8 inches apart. Pest problems are minimized because their new home is a greenhouse bed where celery hasn’t grown for the past two years.

Seedlings from another clump when into individual cells of the APS Propagator; they’ll go outside into the garden in late April. I pulled a few leaves off all these transplanted seedlings so that they don’t lose too much moisture while waiting for their roots to settle into their new homes and get to work.Pricking out celery seedlings
  A lot of celery volunteers are still standing there in the paths and old celery bed. They are now weeds.

Ventura is the One for Me

Slow germination and growth, along with the need for a very rich and constantly moist soil, make celery more of a challenge to grow than most other vegetables. Which is one reason that I grow it!

  And there’s more. If seedlings are exposed to temperatures that are too cold for too long (55° or less for 10 days or more), the plants bolt, sending up seed stalks instead of growing thick, succulent leaves. Older books also talk about blanching celery, that is, piling soil up around the leaf stalks so they turn pale and tender from lack of sunlight. My celery rarely bolts, and I never blanche it.

  One reason for my success with celery (besides, I hope, a greenish thumb) is the variety I grow: Ventura. This variety doesn’t need blanching and is grow thick crisp stalks with rich, but never harsh.Self-sown Ventura celery
  The best celeries I’ve grown were fairly large volunteers that I moved from the greenhouse path into a greenhouse bed one fall. I covered the plants for a few days to increase humidity while the roots were taking hold. All winter, those plants made the juiciest, longest, tastiest celery stalks ever.

Clementines are for More than Just Eating

Clementines are as tasty as the boxes they come in are useful. I can’t bear to throw those boxes out so have a stack of them waiting to be of use.

One box is home to my seed starting supplies: various dibbles and spatulas for lifting small seedlings to replant into larger flats; various sized pieces of plywood for firming soil in seed flats, some with dowels glued to their bottoms to lay out mini-furrows; tape and marking pens for labeling flats; popsicle sticks, also for labeling.Onion seedlings
  Two other boxes are now being used as seedling flats – for onions and leeks, sown in early February and now well on their way. Each box has 5 mini-furrows in which I sprinkled about 7 fresh onion or leek seeds per inch. The seedlings will grow in those boxes until transplant time, which is a couple of weeks before I’ll be planting out the Ventura celery.

 

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!
