NICE HIPS, BUT WHOSE?

2 Contenders for Hips and Rabbi Samuel Redux

As I walked along the beach, I took a look and my first thought was “Nice hips.” But what about the flowers? I’d have to return to the plant next summer to find out, a problem since I was 4 hours from home visiting a relative in Rhode Island.

Most of the roses you see growing seaside are Rosa rugosa. Common names for this plant are Japanese rose, indicating its origin, saltspray rose, indicating its tolerance to beach sand, and rugose rose. “Rugose” means “wrinkled,” which is what leaves of R. rugosa are.

The particular planting of nice-hipped roses staring back at me did not have rugose leaves. What’s more, the hips were about 3/4 of an inch across and bright red. Hips of rugose rose are usually an inch or more across and orangish-red. With this slightly different morphology and the fact that rugose rose is listed as an invasive plant, I assumed that the nice-hipped roses, recently installed as landscape plants, were another species.

Those are Rosa rugosa hips on the left, Rosa canine(?) hips on the right

With such nice hips, the plants could possibly be dog rose, R. canina, the other rose species valued for its hips. The lack of sepals on the hips also pointed the finger at dog rose. (Rugose rose hips have persistent sepals.) A even closer look would have nailed it; rugose rose’s stems have numerous prickles throughout their length while bold, large, wide, downward-facing thorns line dog rose stems. But I didn’t look closer.

Dog rose, although much less frequently seen, is also considered invasive in some places.

Sowing Seeds for More Hips (and Flowers)

As potentially invasive plants, rugose rose or dog rose should be easy to grow from seed. But no. I’ve propagated roses from seed, and it’s a slow process.

Rose seeds, like those of most other fall-ripening seeds of temperate zone plants, have a physiological dormancy that prevents their immediate sprouting, the consequence of which would be death from cold. So they just sit in moist earth until they have experienced a number of hours of chilly temperatures — 30 to 45° F is ideal — before sprouting, at which time winter has presumably given way to spring weather. Instead of moist earth, that chilly habitat could be within the refrigerator in a plastic bag filled with peat moss and perlite.

But rose seeds have another impediment to germination: a tough seed coat. Plant the seed outdoors and shoots might not poke through the surface of the ground for 2 years. The first winter and summer are spent softening the seed coat, making it permeable to moisture. Beginning the second fall, chilling hours begin to accumulate so that by the second spring, the seed can awaken and grow.

I did pluck a few fruits from that Rhode Island, nice-hipped rose bush, and plan to make new bushes. But I’m too impatient to wait 2 years. “Scarifying” the seeds is a quick way to make the seed coats more permeable. Nicking them with a wire cutter does the trick but would be difficult with such small seeds. An hour or so in warm, concentrated sulfuric acid — followed by a thorough rinsing in water — is likewise effective but a bit dangerous. I’ll follow Mother Nature’s lead and soften the seed coats by keeping the seeds warm and moist. No matter how the seed coat is softened, subsequent cool, moist conditions are still needed before the seeds will sprout.

There’s barely time to get those seeds growing this spring. Two months in moist warmth followed by 2 to 3 months in moist peat and perlite in the refrigerator should awaken them. It’s exciting to check the bag in the refrigerator because, once mechanical and chemical barriers to germination have been overcome, a bag of seeds is usually transformed to a bag of white root sprouts, all at once, as if a switch had been turned on.

The Rabbi Multiplies

I’ll have to make up some extra peat-perlite mix. Cutting all the vertical shoots of Rabbi Samuel fig espalier back to the horizontal arms of the permanent “T” framework have yielded a pile of long stems. I can’t bear to throw them away because every foot-long section has the potential to make a whole new plant.

The rooting media for these hardwood cuttings? Peat and perlite again. A bunch of the stems in a deep pot with just their top buds up out of the peat mix should sprout and root by spring.

Not sure what I’ll do with all the resulting fig plants.

So Many Roses, I Hope

I’m also not sure what I’ll do with all the anticipated rose seedlings, especially since I’m not even sure of their species. I did telephone the public works department of the Rhode Island town where the roses were planted and was told that they were Rosa rugosa. I think they are wrong.

No matter: Rosa rugosa is one of the most fragrant roses with deep pink, sometimes white, flowers that are borne all summer long. Also, like dog rose, with nice, fleshy hips, good enough fresh and excellent for jam and tea.

STILL SOME FRESH FRUIT, and GENDER STEREOTYPING

Fruit for My Mouth, Flowers for My Eyes

As I write this, on December 1st, the Rabbi — that’s the Rabbi Samuel fig — is still ripening fruit in my barely heated greenhouse. That’s commendable. Not so commendable, however, is the flavor; cooler temperatures and sparse sunlight have taken their toll. The drooping fruits look ripe and ready to eat, inside and out, but they are no longer worth eating.

On the other hand, another fruit, Szukis American persimmons, hardly look edible but still have rich, sweet flavor. Outdoors, fruits of this variety of American persimmon cling to bare branches. Their orange skins once stretched almost to the point of breaking over the soft flesh within. Now, alternate freezing and thawing temperatures and drier air have sucked moisture and temper from the flesh, so the skins have shriveled and barely cling. Their darkening does nothing to increase the fruits’ visual appeal.

The ripe fruits are hard to distinguish, by eye, from the almost ripe fruits. The latter still retain some mouth-puckering astringency which has given American persimmons a bad name. An unripe persimmon “will draw a man’s mouth awrie with much torment” wrote Captain John Smith 400 years ago. I give Szukis’ branches a slight shake and only ripe fruits come raining to the ground, at which point the Captain’s further words ring true: “When [persimmon] is ripe, it is as delicious as an apricot.”

Can’t Help Wanting African Violets

New leaf cuttings

New leaf cuttings

Man can’t live by bread alone; a feast for the eyes is also in order. Well, maybe not a feast, but an appetizer, some winter flowers. Probably the easiest and most longlasting of winter blossoms are those of African violet. Okay, okay, I know that African violets have been mostly associated with doilies, lace curtains, and other appurtenances of old ladies (nothing against old ladies).

Generally, I don’t even like the color violet. But African violet’s flowers do brighten up a windowsill that looks out upon a gray and brown landscape.

Plantlets forming at bases of leaf cuttings

Plantlets forming at bases of leaf cuttings

Now that I’ve gotten my secret attraction to African violets off my chest, let’s talk horticulture. African violet’s whorl of leaves, like those of many low-growing perennial flowers, is actually a compressed stem, one that has been telescoped down so that each leaf and associated node originates just a fraction of an inch above the next lower leaf. But there is some distance between those nodes, so over time the stem does slowly elongate, rising higher and higher out of the ground. And side branches occasionally sprout forth from the leaf axils. The result of all this is that the potted plant becomes, over time, so overgrown with layer upon layer of leaves that the plant no longer can gather enough energy to flower well.

African Violet in all its glory.

African Violet in all its glory.

The solution to this problem is to make new plants and then chuck the old ones. All that’s needed to make a new plant is a leaf from an old plant and patience. So a few weeks ago I plucked a few leaves (a few, for insurance) from my old, overgrown African violet and plunged their stalks into a moist mix of peat moss and perlite. A plastic bag covering and held above the leaf cuttings by some twigs provided the needed humidity until roots could develop to keep the leaves turgid. Bright but indirect sunlight fueled, via photosynthesis, new root growth, and within a few weeks, resistance to a gentle tug on the leaves told me that roots had developed.

I removed the cover and now little plants are poking up through the ground alongside the leaf stalks. I’m going to transplant my rooted cuttings into larger pots and should, in a few weeks, be enjoying flowers. By then, I’ll have my knitting also ready.

11th Hour Apple Tree Planting

On to less gender stereotyped gardening: tree planting. Picture the day before Thanksgiving, November 26th. A wet snow is falling and beginning to whiten the ground. In my garage are two sturdy, bare root apple trees, a Hudson’s Golden Gem and an Ashmead’s Kernel, recently arrived from Cummins Nursery and needing planting.

Fortunately, I prepared the plantings site a couple of weeks previously with a 4-inch-deep, broad circle of leaf compost, the most immediate purpose of which was to keep the ground from freezing. Rushing to beat out the snow, I pulled enough compost aside to make space to dig holes, spread tree roots out in each hole, backfilled the soil, sifting it around the roots by pressing with my fingers and bouncing the tree up and down, and then settled all into place with a couple of gallons of water per plant.

I like autumn for tree planting. Roots have opportunity to grow in still warm soil (especially if mulched) while stems won’t grow and need water until spring. The soil is crumbly and soft, in good condition for digging and planting. And autumn planting leaves one less thing to do in the flurry of spring gardening.

However, winter temperatures and furry creatures can be a hazard to autumn-planted trees. The first line of defense, to fend off  mice and rabbits and moderate temperatures on the trunk, is a spiral plastic tree guard. An 18” high cylinder of 1/2” hardware cloth provides further defense against mice and rabbits. Beyond that, a higher and wider cylinder of 2×4 fencing should fend off deer and my puppy Sammy. (Past puppies considered newly planted trees as playthings, fun to tug out of the ground.) And finally, the well-furnished, new tree goes into winter with some perfume, a deer-repellant spray, any of which is effective if applied before the plant gets nibbled and renewed monthly.

I expect to harvest the first apples from the new apple trees expected in 3 years.

IT’S ALL ORGANIC, BUT NOT NECESSARILY ALL GOOD

Hay, Grass Clippings, Manure, Leaves — Watch Out!

Organic materials — that is, things that are or were once living — are the core of “organic” agriculture, and right from the get go, many years ago, I set out pitchfork in hand to gather these materials. Into large garbage pails toted around in my van I loaded manure from nearby stables. Neighbors let me haul away their bags of autumn leaves.

I even convinced city workers to dump a truckload of harvested lake weeds onto the side lawn of my small rented house. (That was in Madison, Wisconsin, where fertilizer runoff from lawns was spurring growth of lake weeds which, besides making swimming hazardous, were, upon their death, causing oxygen depletion of the lakes.)

Me mulching, even as a beginning gardener

Me mulching, even as a beginning gardener

Mowings of roadside hay, which I stuffed into the back of the van, were another source of organic matter, used for mulch and for compost. That was before the days of lead-free gasoline, so lead contamination was some concern. Then again, high levels of organic matter in the soil mitigate lead hazards in soils.

More dramatically of concern were bags of grass clippings I once dragged across the yard from my neighbor’s freshly mowed lawn. Hours after I had spread the clippings around my potato’s lush, green vines, their stems twisted and contorted as if screaming in pain — the effect of weedkiller used on the lawn. Perhaps my neighbor was striving for a uniform greensward; perhaps he had inadvertently used a lawn fertilizer laced with weed killer. “Weed and feed” sounds so cheerful and labor-saving. Lawn weedkillers are toxic to broadleaf plants, which means anything but a grass.

The particular weedkiller was probably 2,4-D, also know as Agent Orange (less cheerful-sounding), which is a synthetic category of plant hormone called auxins. At the right concentration and at the right time, whether natural or synthetic, auxins do good things, such as bending plants towards light, initiating root growth in cuttings and in growing plants, and promoting upward growth Otherwise, they can wreak havoc.

I phoned the university extension specialist and was advised to remove the mulch and to adsorb any escaped 2,4-D by mixing activated charcoal into the soil. I did so and subsequent growth was normal.

Home-Grown vs. Imported Hay

I now have the luxury of scything much of the organic material I need from my own one acre field. Early season mowings are succulent and nitrogen-rich, just like grass clippings. Later mowings are hay, dry and carbon-rich. During the growing season, depending on what and when I mow, I can harvest either end of the spectrum, or anything in between.

Wood chips are another good source of organic material, one free of chemicals

Wood chips are another good source of organic material, one free of chemicals

I no longer rely on roadside mowings as organic material for my plantings. They are nowadays too finely chopped for easy and fast scooping up with a pitchfork. Even if that were not the case, I would have second thoughts about bringing such hay on-site. Again, weedkillers are the threat, more insidious these days because of use of more persistent ones. So-called pyridine carboxylic acid weedkillers might hang around in the soil or on sprayed vegetation for anywhere from less than 30 days to several years, even in the manure from animals that have eaten sprayed vegetation!

Caution, Testing, & Time to Avoid Problems

I do still occasionally supplement home-harvested organic materials with imported ones. One source is horse manure from a local stable.

A few weeks ago I was pitching forkful after forkful of manure into the bed of my pickup truck when I glanced over at the far side of the pile and noticed some discarded hay, much of it still pressed together in partial bales. “How convenient,” I thought, for mulching, compost, or bedding for my chickens and ducks.

On my drive home I started thinking about that hay riding behind me. Could it be laced with weedkiller?

For the most straightforward answer, I could just ask the stable owner. A stable hand told me that the hay had been shipped from a few hours away. Rather than cross examine my manure donor, I looked closely at the hay to see if any clover, alfalfa, or other broadleaf plants were mixed in. No. Of course, lack of broadleaf plants does not prove that weedkiller was used.

Well-formed leaves indicate that the hay is free of chemical residues

Well-formed leaves indicate that the hay is free of chemical residues

My final recourse was to do a bioassay of the hay, essentially, to plant seeds in it and observe their growth. Two 4-inch flowerpots, one with chopped up, homegrown hay and the other with the chopped up, imported hay, served as growth media, into which went 3 bean seeds each. Long story short: Growth seemed normal in the imported hay although germination was slower, probably because its texture lent itself to more readily drying out.

To put my mind thoroughly at ease about the hay, I’m going to let the pile sit for a few months, where rain, sun, and, eventually warmth, can do their job in splitting apart the insidious weedkiller molecules. The hay is not for my compost, in the dark innards of which weedkillers, if present, would be particularly persistent.

Autumn Leaves, Good Stuff

Just like the old days, I do still import organic materials in the form of bagged autumn leaves — except a lot more these days. They are both weed- and weedkiller-free.

New Video from Last Summer: Grape Training & Pruning

If you’d like to join me on a brief journey back into summer, see www.leereich.com/videos for a new video, I made last summer, about how to prune that quintessential summer vegetable, tomatoes, just like the Godfather.

A Harvest of Mediterranean Transplants

Mediterranean Delectables & Not So Delectables

Figs thrive in heat and sunlight, nothing like the cold and frequently overcast days we now have, with only a few hours of sun when it does show itself.  Still, my figs keep my attention.
In the greenhouse, heated only enough to keep temperatures above 35°F, the fig trees still have plenty of hard, unripe fruits splayed along their stems. Nothing odd about that. Figs, unlike apples and most other fruits which ripen during a narrow window in time, keep developing and ripening new fruits all along their growing stems.
But only one of my varieties, given the name Rabbi Samuel, seems able to tap into what little sunlight and heat are still at hand. The flavor of fruits that ripen on the heels of a spate of cold, rainy weather falls flat. But whenever sunlight fuels enough photosynthesis in the leaves and warmth in the greenhouse for at least a couple of days, a few fruits will swell and soften, their rosy insides then sweet and richly flavored.

Next Year’s Fig Crop is Readied

Next year’s fig crops are also on my mind.
Greenhouse figs no longer bearing good-tasting fruits get lopped back to 3 to 4 feet high. That dramatic pruning will coax vigorous growth next spring on which new fruits will be borne. More dramatic pruning would coax even more vigorous growth, but the figs on that new growth would begin ripening too late.
Potted figs have also been pruned and moved to my barely heated basement where temperatures below 50°F will restrain growth until outdoor temperatures in spring warm enough so that the pots can be moved back out. Figs are subtropical plants that, when dormant, tolerate temperatures down into the 20s, or lower. If kept too warm in winter, new growth begins indoors. That new growth is tender and easily burned by slight frost or even bright sunlight when moved outside.
Potted figs are difficult to muscle around; mine need to be carried through three doorways and then down narrow stairs to the basement. So a potted fig needs to be kept in a reasonably sized pot even though that allows for only a reasonable amount of growth which, in turn, allows for only a reasonably sized crop.
Digging up Kadota fig

Kadota fig, dug up in November

I worked my way around this problem by taking one of my potted figs, a Kadota, out of its pot and planting it directly in the ground in spring. Theoretically, eager roots reach out into the surrounding soil, enough to support more growth — and larger crops — than if restricted within a pot. Another plus with this method is that no watering is needed beyond an initial drenching.
My success, thus far, has been limited. Kadota may requires too long a season to begin ripening any fruit outdoors here. Still, success might come once the plant gets used to its routine, or I’ll use this method with a shorter season variety such as Brown Turkey.
The time to dig up a planted out fig is anytime before temperatures dip below about 20°F. Or sooner, if the plant has lost its leaves and gone dormant.

The Hunchback of Nice Vindicates Cardoon

Continuing the Mediterranean theme (is this some primal attraction to a Garden of Eden?), I wrote back in May about growing, with reservations,  Gobbo di Nizza (Hunchback of Nice) cardoon. In my garden many years ago, cardoon proved to be an enormous, spiny, bitter-tasting vegetable. But that wasn’t Gobbo di Nizza cardoon.
First off, Gobbo di Nizza is not spiny. It looks spiny but the soft “spines” don’t bite. This is an impressive-looking plant, something like a giant thistle (which it is, as is the closely related artichoke, botanically speaking), a whorl of gray-green leaves (very Mediterranean) soaring almost 4 feet high.
I tasted Gobbo di Nizza a month or so ago and was very unimpressed with its bitter flavor.Cardoon growing in garden
Blanching, which is blocking out sunlight, is a way that the flavor of vegetables such as endive and chicory is mellowed. Some folks blanche cardoon. So I gathered together Gobbo’s leaves, secured them in a tight bundle with a wrapping of twine, and waited a few weeks. Once I had harvested the leaves, removed the blades, and pared away the stringy flesh, I was left holding large, pale leaf stalks, the stalks looking much like celery on steroids.
Chopped into 1” pieces, and drained after being boiled for 15 minutes in salted water, Gobbo di Pizza had a smooth, artichoke-y flavor, quite good. Perhaps it was the olive oil and home-grown sun-dried tomatoes I drizzled over them.Harvested cardoon

Earthy Flavor: What am I, a Worm?

Beets are too earthy in flavor for my palette, and it’s not my imagination. That earthy flavor is from geosmin, a substance that is actually also present in soil! I like my earthiness in the soil, not my food.
Varieties differ in their geosmin concentration, with cylindrical varieties and the striped variety Chioggia being highest. This past season I was duped into growing beets again. I grew the old, low geosmin variety Detroit Dark Red, but still found it too earthy. Most were given away. The few left await vinegar, horseradish, or mustard to tone down their earthiness.Beets in garden

CITRUS IN NEW YORK

Paradise Under Glass, and I Take a Bit of it Home

Wandering in and out of the narrow alleys, I could barely squeeze past other, potential buyers. On my way back from a lecture and book selling, a wad of money was burning a hole in my pocket. I muttered to a young couple who glanced up to let me pass, “I feel like a drug addict.” A fleeting, sympathetic smile, and they, like others, were again intent on the offerings, hardly aware, like us other “addicts,” of other humanity.Inside Logee's Greenhouses.

I was lucky, able to leave Logee’s Greenhouses in Danielson, CT only $75 poorer. But richer in plants. Perched on the tray that I carried to my car were small plants of fragrant wax plant (Hoya odorata), Nordmann Seedless Nagami kumquat, and Golden Nugget mandarin (tangerine), all three promising to offer, for years to come, sweet fragrance, beauty, and good eating in the case of the mandarin and kumquat. By not allowing myself to dawdle, I was able to keep my trembling hand from grabbing at a Black Mission fig plant, a Dwarf Cavendish banana plant (“only 3 feet high!”), or a Hoya lauterbachii, with fragrant blooms the size of teacups. 

Most of Logee’s plants are small and not cheap, understandable considering the wide array of plants they stock. Aside from my kumquat and mandarin, I could have chosen from among a dozen other citrus varieties, including some interesting oddities like Buddah’s Hand Citron, whose fruit does, in fact, look like the draped fingers on a hand. Instead of the fragrant wax plant, I could have driven home with any one of 15 other species or varieties of wax plant. Not that Logee’s is limited only to fragrant or fruiting plants. They stock almost a 100 different kinds of begonias, among other houseplants.

Entering the greenhouses is an experience very unlike that of entering most commercial greenhouses, the latter with their soaring roofs of crystal-clear glass, their buoyant atmosphere, and scoured concrete floors. Logee’s is Paradise for plant lovers, with a mix of concrete and dirt paths so narrow that leaves and tendrils grab at you from either side. Fortunately, plants are more organized at Logee’s than in Paradise: collections of such plants as citrus, passionflower, orchids, and angel’s trumpets are each grouped together. Perhaps the star of the show is the Ponderosa lemon tree, shipped by train then horse and buggy to the greenhouse in 1900 and still bearing crops of grapefruit sized lemons (also called American Wonder lemon and thought to be a hybrid of lemon and citron, originating as a seedling the 1880s). Over the years, it’s given rise to numerous offspring, one of which you can purchase, growing in a 2.5” pot, for $11.95.

Citrus: New Plants from Old

New plants of Ponderosa lemon and other citrus varieties can be propagated one of three ways.

Lemons and limes tend to root easily from cuttings, which are leafy branches with their bases plunged into a moist rooting medium such as a 1:1 mix of perlite and peat moss. Because citrus are evergreen, air around the cuttings has to be kept humid enough so the still-rootless stems don’t dry out. A clear plastic or glass tent does the trick. The leaves need to photosynthesize so they have energy to make roots, so some light is needed. Not too much, though, or the cuttings cook in their tent.

Special rooting hormones, which are synthetic analogues of natural plant hormones, help cuttings to root. Synthetic hormones are used because they decompose more slowly than natural hormones (and in different concentrations, are used as herbicides, such as 2,4-D). Another possibility is to soak the cuttings in water in which have steeped stems of willow, a plant that roots very easily so presumably has some root-stimulating goodies to share. I avoid the hassle of natural or synthetic hormones in rooting cuttings and, instead, pay careful attention to which stems I select for rooting, the rooting medium, and light.

Some citrus varieties can be propagated by seed. Usually a seed-propagated fruit gives rise to a baby different from the mother plant, reflecting the jumbling around of chromosomes as pollen and egg cells united. However, a few plants, and many citrus, exhibit apomyxis, where the seeds, although they look like normal seeds, are formed from cells of only the mother plant.

My new plant acquisitions: hoya and 2 citrus.

My new plant acquisitions: hoya and 2 citrus.

All the seedlings, then, are clones of each other and their mother. Well, not all, because in a given fruit, some seeds may be apomyctic and others may be the product of pollination. The apomyctic seedlings show their presence by their greater vigor and more upright stature.

Downsides to propagation by seedlings, apomyctic or otherwise, are that plants must go through a juvenile phases of some years before they are old enough to flower and fruit. Also, most citrus tend to be very thorny in their youth.

Kumquats Roots for Tangerine Tops

One way I justified my purchases at Logee’s was with my plan to use my new citrus plants to make more plants — by grafting, the third way of propagating citrus. All that’s needed is any citrus rootstock; they all are graft compatible. Not being able to throw away seeds, I have a few kumquat rootstocks started from seeds I spit out from my Meiwa kumquat fruits as I ate them a couple of years ago.

I’ll graft in spring, taking stems from the Golden Nugget mandarin to make a whip graft, a particularly easy kind of graft that gives quick results. Basically, a smooth, sloping cut on the kumquat rootstock will be matched against a similarly smooth, sloping cut on the “scion,” which is the stem I cut from the mandarin stem, with both bound together with a wrap of tape or cut rubber band. After removing leaves from the scion, grafting compound (Tree-Kote) or Parafilm seals the graft and scion against dessication before the scion and rootstock knit together, and the scion piece begins to grow.

The final step will be deciding what to do with my growing citrus orchard in pots. Plants for my annual sale, perhaps? The largest citrus orchard (potted) in the Hudson Valley?

Who’s the Best Gardener/Farmdener?

Fresh Watermelon, and More, with Help from Ethylene

Could I possibly be the best gardener west of the Hudson River? Perhaps. As evidence: On November 1st, here in Zone 5 of New York’s Hudson River Valley, where temperatures already have plummeted more than once to 25°F, I was able to harvest a fresh, dead-ripe watermelon. Not from a greenhouse, not from a hoop house, not even from a plastic covered tunnel. Watermelon, a crop sensitive to frost and thriving best in summer’s sun and searing heat.

Okay, perhaps I can’t assume all that much responsibility for the melon. Let me explain . . . 

Every fall, I have a landscaper dump a whole truckload of leaves vacuumed up from various properties at my holding area for such things. Rain and snow drench the pile in the coming months, starting it on the road to decomposition. When sufficiently warm weather has decided to stay in spring, I scoop out a few holes in the pile, fill them with compost, then tuck in watermelon transplants.

Last fall’s pile yielded well from summer until early fall this year, at which time I gathered up remaining melons for eating or, if unripe, for composting along with the vines. The tractor, with its bucket, was able to move and compact the now dense pile to make way for this  year’s crop of leaves.

 

Ben & Jeremy show off the November watermelon.

Ben & Jeremy show off the November watermelon.

Now we’re up to November 1st, time to spread the leaf mold before it freezes — a big job that necessitated enlisting the help of my neighbors Jeremy and Ben. We were loading and hauling and loading and hauling, forking deeper and deeper into the bowels of the pile, when Jeremy yelled that he’d just speared a watermelon I had overlooked when cleaning up. I cleaned it off and sliced it open. It proved to be a ripe watermelon. The taste? “Awesome,” to quote Jeremy.

The Watermelon Mystery

Okay, I admit to not being able to claim too much credit for the ripe watermelon. How did it get there? Was it ripe and overlooked, then buried and preserved in the warm bowels of the leaf mold pile? Was it unripe when buried, then subsequently ripened? Probably not. No leaves were poking out of the pile, capturing the sun’s albeit weak rays for photosynthesis to make the sugars needed for ripening. A couple of nights of 25°F would have done in the leaves anyway.

Some fruits can actually ripen after harvest. These include apples, pears, bananas, avocados, and other so-called climacteric fruits. Just before ripening, respiration of climacteric fruits dramatically increases along with a burst in production of the plant hormone ethylene. Through a feedback mechanism, ethylene stimulates more respiration which in turn stimulates even more ethylene production and even quicker ripening. Hence, enclosing bananas in a bag stimulates ripening, and why one rotten apple — injury, whether mechanical or from pests, also elicits an ethylene response — can indeed “spoil the barrel.”

This burst in ethylene production occurs even after climacteric fruits have been harvested, as long as they were sufficiently mature at the time. You can’t pick a golfball-sized green apple and expect it to ripen off the plant.

Non-climacteric fruits lack that pre-ripening spike in respiration and ethylene production, and do not ripen after harvest. Or so the thinking, based on early experiments, went. According to more recent research, fruits show various degrees of ethylene production. Watermelon is not a climacteric fruit, but at a certain point the white flesh within does release a burst of ethylene some time after which it morphs from bland and unripe to sweet, red, and ripe. But that won’t happen off the vine.

(“Ripe” is open to some debate. Peach, for instance, is a climacteric fruit that, if picked sufficiently mature but underripe, will soften and become more edible. But it won’t develop the aromatics of a tree-ripened fruit or, until rotting changes starches to sugars, become at all sweeter after picking. I don’t call that “ripe.”)

So my watermelon must have been overlooked and ripe and evidently kept perfectly well in the moist warmth of the leaf pile.

Deb & Ethylene Take Credit for the Peppers

Ethylene, and not me, is going to take credit for the fresh, sweet red peppers in today’s salad. Peppers are a climacteric fruit. Green peppers are unripe peppers, but if the fruits have just a hint of red on them, they can ripen even after harvest to full red (or yellow, orange, or purple, depending on the variety of pepper) color and, at least to my taste buds, flavor.

Still eating fresh, red, ripe sweet, juicy, delicious peppers.

Still eating fresh, red, ripe sweet, juicy, delicious peppers.

Skill is needed to ripen peppers off the plant. Cool, but not too cool, temperatures hold the fruits for storage and warmer temperatures then speed ripening. Just the right amount of humidity is also needed to, on the one hand, avoid drying, or, on the other hand, rotting. My wife, Deb, rather than I, plies these skills, so should probably get credit for the ripe, red peppers.

This season has been the best pepper season ever, both in quantity and in quality. King of the North peppers, large and blocky, with thick, juicy walls, now ripening in a basket taste as bland now as they did all summer. I won’t grow them again. In contrast, Carmen, Sweet Italia, and (slightly hot) Pepperocini peppers, also ripening in that basket, taste as good now as their siblings did snapped from plants basking in summer heat and sun a few months ago.

HOME-MADE TOOLS, GOOD, BAD, AND SOMETIMES IMPOSSIBLE

Needed Now, A Hay Rake, Garden Line, & Bulb Planter

The small meadow that stretches south of my vegetable garden is more than just a meadow. It also provides mulch for my trees and shrubs, and food for my compost “pet.” All this necessitates moving the greenery — or brownery, when it’s old — from the field to the trees, shrubs, and compost bins. I cut the hay with a scythe, gather it together with a rake, scoop it up with a 4-tine pitchfork, then pile it high in the garden cart for transport.

The tools needed seem straightforward enough, except for the rake. An ordinary garden rake would not do. It’s too small for so large an area and its heavy, short, sharp teeth would too readily tangle up in the mown hay without reaching deeply enough too grab a sufficient amount with each pull. A leaf rake likewise would not do; the fine teeth would merely skim the surface layer of hay or break off.

Years ago, rather than purchase a bona fide hay rake, which may or may not have worked as expected, I thought I’d save some money and get just what I wanted by making one. A quickly made homemade rake would tide me over until I felt like purchasing one or made a new one, improved by my experience using the original. That was years and years ago! The old wooden rake, originally with dowel teeth, later upgraded to teeth of metal spikes, and handle made from a long tree branch, served me well. Eventually, sun, rain, and use tore it apart.

Recently, after looking over all the options — including an antique wooden hay rake, a “professional” rake, a “grading rake” — and not knowing which might work best, I decided, once again, to make one.

And proud I am of my new rake, both in function and beauty. Four-inch lengths of aluminum dowels, rounded at their bottoms with a grinder, are evenly spaced and firmly anchored with small screws at their tops and the upper part of their sides to a 40 inch wide piece of aluminum angle stock to make up the head. A short piece of aluminum angle stock in the middle of the head provides an anchor for the handle, which starts out as an 18” length of 1” diameter PVC pipe. To complete the handle, I slid into the PVC pipe a 7 foot long, straight, strong piece of bamboo, home grown. The rake is a meeting of universes, two corners of the high tech, embodied by aluminum and plastic, with the natural, bamboo. They seem happy together.

Bad Home-Made

With all that’s available in stores and online, it may seem archaic to fashion one’s own tools. But doing so — as is the case with my new rake — can get you a custom-made implement, exactly to your particular specifications. I had the luxury and job of choosing the length and spacing of my rake’s teeth as well as the width of its head, even its weight, depending on the materials I chose. The finished product works well and everything, from lining up drilled holes as I seated the teeth into position to choosing a bamboo handle to fit securely into its PVC sleeve was very satisfying work.

Garden line, a design failure for me

Garden line, a design failure for me


Such is not always the case with homemade. Years ago I needed a garden line that could be wound up quickly and easily, and mounted on a spike that could be stuck in the ground. I made one. Not a very good one in form or function. It’s time to finally cannabalize it for its string which I’ll just wind up around a piece of wood — for now.

Good Bought or Borrowed

Okay, some gardening tools cannot be homemade so are better bought. Case in point: I’m hoping for a dramatic planting of ornamental alliums in part of the meadow. Dramatic, as in 125 bulbs, 100 of which (Purple Sensation) will make purple globes 4 inches across, and 25 of which (Ambassador) will have purple heads 7 inches across, all these heads sitting high atop 3 to 4 foot high stalks. The hope is that their leaves will be up, do their photosynthetic job, and be out of the way before the surrounding grasses and herbs pick up enough steam to choke them out. If so, allium flowers will brighten the meadow year after year.

Pushing a shovel through dirt and roots 125 times would be an arduous task indeed. So I borrowed an earth auger from my friend Bill and inserted it into the chuck of my Black & Decker 20 volt cordless drill. If it seems as if, by explicitly naming it, I’m promoting this Black & Decker product, I am. The tool has power, longlasting power, enough to muscle the auger 6 inches deep into the soil. (Full disclosure: No rocks here.) In one hour, all the bulbs were planted.

No, I’m not about to cobble together a cordless drill. Same goes for the earth auger. This particular one, borrowed, was an antique, cast from solid steel.

The humongous Ambassador alliums were too large for the auger holes so I did have to dig those 25 holes by hand.

Farmdening, Not Too Much

Earlier, I mentioned using a scythe to mow the vegetation. The scythe is an archaic yet very useful and enjoyable tool, but, as Charles Dudley Warner wrote in his 1871 classic My Summer in the Garden, “Blessed be agriculture! If one does not have too much of it.”

At one time I did mow the whole, one acre meadow with a scythe — 3 times each season so that the vegetation would not get too long to be mowed. No longer. That much scything got tedious, and I got tennis elbow. So now the scythe takes care of my mowing enough hay for my mulch and compost needs, and a Kubota tractor with a brush hog, once a year, takes care of the rest.

FIGS UP NORTH

Who Says I Can’t Grow Figs? A Mouse?

Crisp weather notwithstanding, almost every day I can reach up into the branches of my fig trees and walk away clutching a handful of soft, dead-ripe fruits. That’s because the trees, the ones bearing fruit, are in the greenhouse, where nights are chilly but daytime temperatures, especially on sunny days, are balmy or hot.

I’m not gloating. Those greenhouse figs take some work beyond normal routines of keeping heating, cooling, and watering systems chugging along harmoniously in the greenhouse. Earlier in the season I battled cottony cushion scale insects with toothbrush and soapy water, with oil sprays, and with sticky band traps (for ants, which “farm” scale insects) on trunks. Now I see the insects are staging a comeback at a time when the trees are too big to scrub with a toothbrush and too big, too laden with fruit, and surrounded too closely by lettuce, celery, and other winter edibles to spray oil. I’m hoping natural conditions keep scale insects in check until cold weather and lack of leaves or fruit finally puts them asleep for a few months.

A few weeks ago, some creature — a mouse is my guess — discovered the figs, and liked them. He, or she, chewed the bottoms of some fruits as they hung from branches and gathered others to cache in shallow tunnels. Traps, poison bait, and wide girths of sticky Tangle-Trap returned fruits to their rightful owner, me.

All this effort is worthwhile. Especially on sunny days, the figs are delectable, soft and sweet like dollops of jam hanging from the branches.

So Many Varieties, So Little Space

Growing a few varieties of figs makes fig-eating even more pleasurable. People wonder, on hearing that I grow figs, whether I grow “brown figs or white figs,” at which point I bring attention to the fact that there are hundreds of varieties of figs, with many of each color.

I keep trying to pare down my collection to the best. Instead, I seem to be adding varieties either deliberately or gifted. It’s hard, virtually impossible, to tell what variety you have until it fruits. Figs have been cultivated for thousands of years, along the way of which an older variety may have picked up many names. For instance, I have a variety I purchased as Verte (syn. Green Ischia); with brown fruit, I knew it was mislabeled. Its bearing habit and the appearance of the fruit nailed it down as San Piero, also known as Negro Largo, Douro Black, Aubique Noir, Large Blue, Lee’s Perpetual, and California Brown Turkey, among other names. The name California Brown Turkey distinguishes it from Eastern Brown Turkey, a totally different variety that I also grow and which itself is also known as English Brown Turkey, Everbearing, and Texas Everbearing,.

A few years ago, a woman on Millrock Road here in town, offered me her potted fig tree; she was moving and didn’t want to take it with her. (Understandable: I also didn’t take all my 35 varieties of fig from my garden in Maryland when I moved up here to the Hudson Valley.) Still hers was an offer I could not refuse; perhaps that potted plant would bear the best fig ever. In a pot in the greenhouse this year, the tree finally bore fruit, greenish yellow and round, with the insides bursting to split the skin. It’s a keeper, and I’m adding to the nomenclature confusion by calling it Millrock fig until I learn otherwise.

Another fig, this one named by Jack Algiere, the farmer at Stone Barns farm, is bearing heavily and looks to keep doing so for weeks to come. I have espaliered this tree, Rabbi Samuel, against a greenhouse wall in the form of a permanent, low T. Fruiting shoots rise vertically about 6 inches apart from the upper side of each arm. This variety bears best on new shoots so my plan is to each winter cut all vertical stems down near the arms and then thin out new growth so vertical shoots are no closer that 6 inches apart. The Rabbi’s fruits are humongous, as big as small apples.

Subtropical, But Thankfully Adaptable

What makes figs so popular a fruit, even in climates far removed from the hot summers and mild winters it calls home? Perhaps a love for this ancient fruit, whose provenance is in one cradle of civilization, is coded into our DNA. And, of course, the flavor, sweet and juicy without being cloying.

Although a subtropical plant, fig is accommodating to colder climates. You can hack back its roots — useful when providing new potting soil for pot-grown plants. It’s deciduous, so doesn’t need light in winter — useful in northern climates when looking for a cold, but not too cold, place to store the dormant plant. Most varieties do not need pollination to set fruit. And figs bear quickly and propagate easily.

Most important, in contrast to most temperate-zone fruits, fig plants can bear on new wood. Some varieties bear on one-year-old wood and some bear on both old and new wood. Bearing on new wood — as does Rabbi Samuel — makes it convenient to cut back a potted plant when maneuvering it indoors for winter. Or if winter cold kills part of the top of an outdoor plant. In either case, a plant that loses too much of its top requires a longer growing season before fruits start ripening.

Fruits keep ripening along new shoots, as they grow, until arrested by cold. Hence, my prediction for a few more weeks of fruit from Rabbi Samuel in the greenhouse. Those fruits hang in stark contrast to the scene outdoors, where leaves of tomato, pepper, and other tender plants have been blackened by the first killing frost here of 25°F, on October 19th.

FIGS, POMEGRANATES, LETTUCE, BEDS: ALL READY

 Beds Ready for Spring Planting, Figs and Lettuces Readied for Cold

Much colder weather has been sneaking in and out of the garden but leaving traces of its presence with some blackened leaves on frost-sensitive plants and threatening to brazenly show itself in full force sometime soon. This fall I vow to put all in order before that event rather than, on some very cold night, running around, flashlight in hand, gathering and protecting plants.

Before even getting to the plants, drip irrigation must be readied for winter. Main lines and drip lines can remain outdoors but right near the spigot, the timer, the filter, and pressure reducer must be brought indoors where they won’t freeze. I plug the inlet for the drip’s main line to keep out curious insects. At the far end of the line is a cap that I loosen enough to let water drain out. Opening all other valves along the line leaves no dead ends in which freezing water could expand to break lines.

Begonia, amaryllis, Maid of Orleans jasmine (Jasminium sambac), and other topical plants are next in importance. Being near the radiating warmth of the house has spared them recent slightly frosty nights. Colder temperatures would not be so kind. I snap the stems off the begonias right at ground level and put the pots in the basement where cool temperatures will keep the tubers dormant to wait out winter. Amaryllis plants also go into the basement. Cool temperatures and lack of water for a couple of months give these plants the rest period they need so that, brought upstairs to a warm, sunny window, their blossoms can show off their bright, red color against the achromatic winter landscape beyond.

Maid of Orleans jasmine right away gets a prominent place in a sunny window to share its nonstop, sweet fragrant blossoms.

Figs, Pomegranates, & Subtropicals Readied for Cold, But Not Too Much

Fig, pineapple guava, Chilean guava, and pomegranate are subtropical plants that tolerate temperatures down into the ‘teens so can remain outdoors for weeks to come. Still, many of these plants are in large pots, not something I want to be lugging around following at last minute threat of frigid temperatures. So I’ll gather them together in a convenient location for quick dispatch indoors when needed.

The guavas, as well as kumquat and common jasmine (Jasminium officinale), are evergreen subtropical plants. The leaves are important to these plants both for beauty and for function so they’ll make the move indoors before the other subtropicals to make sure their leaves go into winter undamaged.

Common jasmine stays out longest because some exposure to cold is needed to get blossoms in winter.

Cold Weather Vegetables for Weeks to Come

The vegetable garden is still green with endive, kale, lettuce, turnips, Brussels sprouts, arugula, and other cold-hardy vegetables. Soon, though, their cold tolerances will be tested. I’ll pre-empt that testing by covering some of the beds with tunnels of fabric (“fleece” to the Brits, “floating row covers” to us colonists) or clear plastic. No need yet to cover the plants but better to have the metal hoops which support the fleece or plastic in place and ready for the covering before that frigid night to come.

Not all hardy vegetables get covered; just the leafy ones — lettuce, mustard, arugula, and endive — for fresh salads in the weeks to come. Brussels sprouts and kale are so cold hardy that they can go for weeks without protection, and, anyway, they’re too tall to cover. Leeks also can stay outdoors unprotected until December, or later, then get dug up and packed together in a box or large pot to store in the basement and use as needed.

Carrots, beets, turnips, and winter radishes enjoy the protection of the earth. With a deep mulch of leaves or straw, they could remain tender and unfrozen all winter. More convenient for eating is to dig them up just before really frigid weather descends on the garden and pack them in boxes with dry leaves to store in the cool temperatures of the basement. I’m putting off deciding which option to choose.

Fresh Lettuce ‘Til When?

Someone recently told me that they gardened maniacally all summer and now they are finished for the season  . . . which reminds me of some more things that I still have to do. Plant garlic. I planted cloves back in early September; a second planting, now, will give some indication if early or late planting is better. Mulch blueberries as soon as their leaves all drop. Sift compost and garden soil into buckets to store for making potting soil in late winter. Cut down asparagus plants after the tops yellow, and mulch the bed. Clean up spent vegetable beds of tomatoes, peppers, and eggplants and spread them with an inch depth of compost. Mow hayfield and lawn to expose rodents to predators and, in the hayfield, to keep blackberry, sumac, and autumn olive from taking over. Plant bulbs (a large, naturalized planting of alliums; more on that some other time).

I’d also like to divide older plants in a flower bed and dig out weeds that are starting to think they’re home. And build a rustic fence to hid the propane tank for the greenhouse.

I’m not yet ready to throw in the trowel for this season.
