NUTS, SOME GOOD, SOME BAD, AND NEW(!) PLANTS

/2 Comments/in , , , /by

 

A Good Harvest, But . . .

The black walnut harvest was abundant this past fall. Back in October, we gathered about a dozen 5-gallon buckets of of unhusked nuts, and, after husking, cleaning and drying them, set them in the cool, dry, squirrel-proof loft of our garage/barn (gabarn?).

The nuts are now sufficiently cured and ready for cracking. Two tools have made quicker, easier, pain-free, and more effective the once difficult and thumb-threatening job needing a concrete floor and a hammer. The Master Nutcracker makes elegant use of cogs and levers. For any nutmeats still gripped in a piece of shell, a “diagonal cutting plier” nips the shell piece to create a fault line that opens to drop out a piece of nutmeat, or to twists off a piece not fully cracked.Black walnuts and Master Nutcracker

This year’s harvest was from two trees. Most was gathered from the ground beneath a decades-old tree. That tree grows on what, in spring, is periodically waterfront property when the swale that it borders fills with rushing water. The other tree sprouted in well-drained soil a few years ago at the edge of woods along the north edge of our property. Now with an 8-inch diameter trunk, it began yielding nuts in earnest only a few years ago.

The opening day of nut-cracking season has highlighted the difference in nuts. Nuts from the younger tree not only are significantly larger, but they’re all well-filled with nutmeats that come out in large pieces. The old tree has yielded too many nutmeats that are dark brown and shriveled, or totally dried out, black, shriveled, and inedible.Good nuts and shriveled nuts

Genetics could be at play. Although both trees are black walnuts, each is a distinct individual within the species. Water might also figure in. Periodic flooding in the spring might leave too many of the old tree’s roots gasping for air at critical moments in nut development. Perhaps the old tree is still recovering from being swamped in water a few feet up its trunk during hurricane Irene back in 2011.

Perhaps it’s age. Probably not. Black walnuts are long-lived trees and I assume their fecundity goes hand in hand with their longevity.

Up to a few years ago, the large, old tree bore regular and reliable nuts that were plump with nutmeats.

Winter Dreaming

You’d think, after gardening for so many years with sufficient room for planting, that I would have by now grown every plant I could possibly want. Not so!

Cleaning up my desk, I recently came across a pile of papers clipped together, my pile of “plants to grow.” Over the years, whenever I see a plant of interest in a magazine or newspaper, I’ve torn out the page to add to the collection. The same goes for plants I might come across on the web or in conversation.Plants to grow

Swelling over the years, the pile has become intimidating. Daring to look at it would force me to decide whether such and such still worth growing and, if so, where to plant it. If an ornamental plant, where to incorporate it harmoniously into the landscape? If an edible, where best to site it for convenience in care and harvest? And do I have time to care for yet another plant? If there’s a plant offering both good eating and good looks, how to . . . well, you get the picture.

Perhaps the approach should be the same that some guy with too large a collection of shoes or some gal with too large a collection of cars might take: Vow to get rid of one for each new one collected. Or not.

Now Really, What To Plant Next Year

Okay, I’ve segregated the pile of “plants to grow” into two piles, one for plants to order this coming spring, and one for plants to keep on the back burner.

At the top of my list are three daphnes. I already grow Carol Mackie (Daphne × burkwoodii) for its fragrance and white-picoteed leave; the new daphnes can share a bed with her. Briggs’ Moonlight (D. × burkwoodii) has the reverse leaves, white with a green-picotee — a nice foil for Carol Mackie. Joining them will be Summer Ice (D. x transatlantica), which has just a thin line of white on its leaf edges. Also February Daphne (D. x mezereum), this one for its rosy-purple flowers that open in early spring on leafless shoots. All these daphnes are attractive but their main draw, for me, is the flowers’ jasmine-like perfume. They will make sitting on the nearby deck an olfactory delight from early spring right through summer.

How can I resist a plant called roof iris (Iris tectorum), both for its flowers and low fountains of foliage? It tolerates cold or dry conditions, and grows in sun or shade, so would be a perfect addition in name, needs, and appearance for MY green roof.

Another perennial slated for entrance next year is royal catchfly (Silene regia), a native of American prairies with fire engine red flowers. My plan is to grow them from seed to get enough seedlings to  plant in part of MY meadow.

That’s all for the coming year. What, no fruits, one of my specialties? No, I have all I need. Hmmm . . . what about quince?

IN WITH ENDIVE, OUT WITH ASPARAGUS

First Harvest At Season’s End

Finally, I’m harvesting endive from the garden, just as planned when I settled seeds into mini-furrows in a seed flat back in July. After leaves unfolded on the seedlings, I gently lifted them up and out of their seed flat, helping them up with a spatula slid beneath their roots, and into individual cells in a GrowEase Seed Starter.Endive seedlings

Also as planned, a bed in the vegetable garden was freed up from harvested sweet corn in early September. After removing corn stalks and slathering an inch of compost on top of the bed, the endive plants were snuggled in, 2 rows down the 3-foot-wide bed, with one foot between the plants in each row. In October, I laid row cover over the plants, plus a tunnel of clear plastic film supported by hoops, to protect plants from bitterest cold.Endive under plastic tunnel

Endive harvest could have begun earlier. But there was no need to, with so much other fresh salad fixings in the garden. And cold weather anyway helps bring out the best in endive. The inner leaves, partially blanched as they folded in among themselves from close planting, are now especially sweet, succulent, tender, and tasty. 

What Endive, Who?

Just to be clear on the identity of my endive, it’s botanically Cichorium endivia var. latifolia, also called escarole, broad-leaved endive, or Batavian endive. Besides delicious fresh, it’s a key ingredient in the classic Italian white bean and endive soup.

I used to also grow another endive, C. endivia var. crispum, also called curly endive or frisée. It’s very similar, except for frilly leaves. In my experience, it’s less succulent and more easily damaged by cold.endive and beets

We’re not yet finished with “endives.” There’s also Cichorium intybus, also known as Belgian endive or witloof chicory, with small heads that are torpedo-shaped and pale green or white.

More machinations are needed to grow this Belgian endive, beginning with sowing in spring and waiting the whole season for a large taproot to develp. At season’s end, the roots are dug up, trimmed to a foot or so long, then packed together upright in boxes of loose potting soil, sawdust, or anything else that will hold moisture. The roots resprout, and the goal is to keep the developing heads in the dark, either by putting a few inch depth of sawdust or sand over the roots or by keeping the whole box in darkness. Too much trouble for me. Plus, very little flavor. (Also, mine weren’t all that successful.)

Bye, Bye Asparagus

Speaking of pale leaves, I’m happy that my asparagus’ leaves yellowed a couple of weeks ago. The plants had been growing vigorously all season since harvest ended in July, the green stems and leaves gathering sunlight to pump energy down to the roots, to store and then fuel next year’s growth of the young spears. Finally, the plants yellowed as what nutrients were still left in the stems and leaves headed downward, to the roots.

My short-bladed brush scythe was the perfect tool to make quick work of the plants, a fluffy addition to the compost pile.

After July, germinating and growing weeds became too hard to reach and root out among the 6-foot-high forest of feathery stalks. With the asparagus shoots and leaves cleared away, I was recently able get into that bed for a final weeding. The two-inch-deep mulch of leaf mold I spread after weeding will slow weeds down next year, conserve soil moisture, and feed soil microbes and, in turn, the asparagus plants for what I predict will be a bountiful harvest.

SENSORY DELIGHTS, NOW AND FUTURE

/9 Comments/in , , , , /by

A Scented Wave

    For the past couple of weeks, every time I walk upstairs to my home office, a sweet aroma hits me like a wave a few steps before I reach the top stair. This wave pulls me forward, a room and a half away, to the Meyer lemon plant sitting in my office’s sunny, south-facing window.Meyer lemon tree in pot
    The wave began when only a single Meyer lemon flower had opened. Now, the plant, only a foot and a half high, is decked out with more than 20 flowers.
    This “tree” started life as a cutting I took from a friend’s old tree that anyway needed some pruning. With their bottom leaves stripped off, the 6 inch long stems rooted reliably in a few weeks after their bottom portions were plunged into a moist mix of equal parts peat and perlite, and transpiration was reduced with a clear plastic overhead. Bright, but indirect, light allowed for photosynthesis without cooking the plants in their “mini-greenhouse.”
    My most important job now is to keep an eye out for scale insects, which show up as either brown bumps (armored scale) or cottony tufts (cottony cushion scale) on leaves and stems. Rubbing off these insects or dabbing them with a Q-tip soaked in alcohol deals with them unless the population gets out of hand. Repeated sprays with horticultural oil can be the next line of defense.Pollinating Meyer lemon
    Every couple of days I pick up the artist’s brush lying next to the potted plant, and dab it on the tips of some of the flowers. I’m not painting; I’m picking up the yellow pollen from each flower’s male anthers and dusting it onto each flower’s, and neighboring flower’s, female stigmas.
    A good proportion of those pollinated flowers should go on to provide the next treat from Meyer lemon, fruit, which this plant usually bears prolifically. Meyer lemon is actually a hybrid of lemon and sweet orange, with both parents reflected in the flavor. A final plus for this plant is, in contrast to many other citrus plants, is that its stems lack thorns.

Another Fig Option

    Greenhouse figs still bear fruit; with low light and cool temperatures, they’re not worth eating. I did recently harvest a few figs from a Kadota fig plant that had been planted outdoors.
    “Had been planted outdoors?” So where is it now? It’s still outdoors, but not planted. It’s in a pot. Like my few other potted figs, the potted Kadota plant will move down to the basement before temperatures drop below 20°F.Potted Kadota fig in ground
    Unlike my other potted figs, the Kadota plant did not require daily watering all summer. Or yearly root pruning and repotting to give the roots new room to grow and explore. The reason is because Kadota is in an 18” diameter plastic pot with some holes I drilled in its side. In spring, I sunk the pot up to its rim into a waiting hole in a bed on the sunny, south side of my house. The plant’s roots wandered outside the pot into the surrounding soil through the existing opening in the bottom of the pot, as well as through the side openings. Once outside the pot, roots were able to fend for themselves garnering water and nutrients for the small tree.Potted Kadota, out of ground
    Kadota, like many other fig varieties (but few other kinds of fruits), bears fruit on new shoots. Very convenient. Rather than having to squeeze spreading limbs down my narrow basement stairs, I can cut back all the stems rather drastically, which also has the benefit of stimulating vigorous, new shoots at the cut stub, new shoots that will bear fruit next year. Not too drastically, though, or too long a time might be required for the fruit to develop and ripen. And Kadota is already a late ripening variety.
    Of all my figs, Kadota is my favorite, both for its almost chewy skin and the rich, sweet flavor lying within. Even those recently harvested ones.

Comely, Fragrant, and Poisonous

    Another sensory treat slated for winter comes compliments of Angels’ Trumpets (Brugmansia spp.). The flowers of these poisonous(!), subtropical trees are giant, 6 inch long trumpets in pale colors and from which wafts a delicious aroma, especially at night. These subtropical plants can grow into trees but are easily kept much small, in pots, in cold climates.

Angels Trumpets, in past years

Angels Trumpets, in past years

    I neglected my plant all summer and on into fall; when I retrieved it to protect it from coldest nights, it was just about leafless and ready for the compost pile. Then I noticed some small leaves beginning to develop along its almost bare stems. And some stems had the beginnings of flowers on them.
    So I brought Angels’ Trumpet indoors, next to a sunny window (and next to the Meyer lemon). It looks sad now but should revive and, judging from my previous experiences with this plant, flower well most of winter. In summer, with long days, it takes a rest from flowering — which is why I ignored the plant.

UBER ORGANIC & A BEAUTIFUL BLOSSOM

/0 Comments/in , , , , /by

‘Tis the Season

    ’Tis the season to really put the “organic” in organic gardening. “Organic,” as in organic materials, natural compounds composed mostly of carbon, hydrogen, and oxygen. “Organic,” as in materials that are or were once living, things like compost, leaves, manure, and hay.Vegetable beds in autumn
    I’ve spread compost over almost all my vegetable garden beds. A one inch depth laid atop each bed provides all the nutrients the vegetable plants need for a whole season, in addition to other benefits such as snuffing out weeds, holding moisture, improving aeration, and nurturing beneficial, pest-fighting organisms.Compost piles
    I’m also finishing up the bulk of making new compost for the year. Pretty much everything organic — old vegetable plants, kitchen trimmings, even old cotton clothing — go into the compost piles. The primary foods, though, are hay, which I scythe, rake up, and then haul over from my hayfield, and horse manure, which I pitchfork into the bed of my truck, then unload into a garden cart to haul over to the compost bins.
    Autumn leaves piled up last year have rotted down into “leaf mold,” essentially the same material as compost, with the same benefits. This pile arrived as a truckload last autumn thanks to the generosity of a local landscaper. The leaf mold isn’t quite as thoroughly broken down as the compost so I’m hauling that over to all my young trees and shrubs, and then spreading it beneath them.
    I’m also on the lookout for trash bags stuffed with leaves. Local leaf gatherers/baggers contact me when bags are ready for pickup. I toss the bulging bags into the bed of my pickup truck, then haul them over to and unbag them beneath my blueberry, raspberry, currant, and gooseberry bushes.

Organic Matters

    All this compost, hay, manure, leaf mold, and leaves are food for soil organisms. Most of the food is carbohydrates, the carbon, hydrogen, and oxygen that combine to make sugars, starches, cellulose, chitin, and pectin of living organisms. As carbohydrates are gobbled up, nutrients are released for plants.
    In their raw state, these organic materials are relatively low in plant nutrients. Compare the one pound of phosphate you get from ten pounds of 10-10-10 chemical fertilizer with the 100 pounds of compost you need to offer  that same amount of phosphorus.Raking hayfield
    You could get that one pound of phosphate from only ten pounds of an “organic” source such as bone meal. That would be easier than shoveling out 100 pounds of compost — but the soil would then be deprived of 90 pounds of carbohydrate and other bulk that feeds soil organisms and, in turn, bestows physical, nutritional, and biological benefits in the soil.
    So I’m continuing to haul manure, hay, leaves, leaf mold, and compost for my garden. It’s also good exercise.  

A Beaut’ Worth Reviving for Winter

    Much lighter work is digging up an amaryllis bulb. I’ve always considered amaryllis too gaudy a plant, one giant, often flaming red flower appearing atop a bare stalk in early winter. And then, last autumn, someone sent me a big, fat amaryllis bulb along with a pot to plant it in, as well as some potting mix. How could I help but plant it?

Amaryllis now

Amaryllis now

    The flowers were prolific and awesome, flower after flower (yes, flaming red) appearing on each stalk, and stalk after stalk of flowers. This one was a keeper.
    Green leaves, the more the better, are what fuel the following year’s blossoms. (One flower stalk for every nine leaves, according to one source.) Periodic little fertilizer and, as needed, water kept the plant growing well until warm weather settled in for good in spring. Then I tipped the bulb out of its pot and nestled into a hole in a bed in part shade with rich soil and drip irrigation.

Amaryllis late last winter

Amaryllis late last winter

    Just before a night when temperatures dipped into the low 20s, I dug up the bulb and potted it up. It now sits, unwatered and leafless, in the cool temperatures of my north-facing mudroom. A couple of months of cool temperatures, 50 to 60°F, is good for waking up the flower buds within the now fatter bulb — and its small, baby pup, thank you.

CHANGING STEMS, CHANGING LEAVES

Korean Giant Pear, In Training

    Stepping down the two stones at one end of my bluestone wall, a friend looked up and asked, “Are you torturing or training this tree?” He was referring to the tree on one side of the the stairway, one long stem of which was arching overhead, held in that position with a string tied to a stone on the opposite side of the stairway.
    “Training,” I replied. The stem was being coaxed into this seemingly submissive position both for form and function. Not to inflict pain.Pear branch, bent in training
    But first, something about this tree. It is an Asian pear, the variety Seuri Li that I created many years ago by grafting a Seuri Li stem on a semi-dwarfing rootstock (OH x F 513). It’s initial training was as an en arcure espalier. Deer found the young pear trees sitting high enough on the backfilled soil behind the wall a convenient smorgasbord; they didn’t even have to bend down to nibble at them. So the espalier became a deer-modified en arcure.
    Seuri Li never bore as well as the other Asian pears — Yoinashi, Yakumo, and Chojuro — trained above that wall. Last year I lopped back one major stem of Seuri Li and grafted a stem of the variety Korean Giant onto the stump. The graft “took,” and fueled by the established root system, buds from the grafted stem soared skyward.
    Growth from the graft was vigorous enough to start a large arch over the two stone stairway. A very big en arcure.

Hormonal Control

    Training to en arcure entails bending the single stem of a young fruit tree over to its neighbor. Typically, a bud near the high point of the arch will grow out into a vigorous shoot which is then bent in an arch in the opposite direction, to its neighbor on the other side. The vigorous shoot growing from the high point of that second arch is trained back to the next tier of arch  of first neighbor. And so on, as high as desired.
    The end result is a flat plane of adjacent trees decoratively linked as a living fence.
    The fence might be considered functional, but the truly functional aspect of en arcure is physiological. Enhanced vigor of the highest buds can be traced to a plant hormone, auxin. Auxin, present in all plants, is synthesized in the uppermost growing points of a plant, either the tip of a vertical stem or the high point of an arched stem. But this auxin also puts the brakes, to some degree, on growth from buds below that high point.
    Growing fruit takes energy, as does growing stems; more fruit means less stem growth, and vice versa. (Left to their own devices, plants more or less balance these needs themselves, although not always to our satisfaction, which is why you have to pluck off peach fruitlets so that a peach tree can pump more energy into the fewer — and resulting — tastier fruits that remain.) Bending a branch over quells its growth, coaxing it to divert more energy to making fruit — except for the uppermost bud, which puts out a vigorous shoot.
    My plan, then, is to have that long stem of Korean Giant pear festooned with flowers in spring and fruits in autumn as it arches over the stone stairs. Plants don’t read plant physiology books and tow the line to all this theory, but I’m confident in a fruitful, decorative future for my plant because Asian pears generally are very eager to bear fruit.

Uncommon Autumn Color

    Speaking of physiology, I wrote last week about the carotenoids, tannins, and anthocyanins that make autumn so warmly colorful, and especially so this year here in the Hudson Valley. A few plants, not commonly planted, are contributing boldly to that warmth.
    •Japanese Stewartia (Stewartia pseudocamellia) earns its keep year-round, with rich, red autumn leaf color right now, bark mottled in hues of gray and brown in winter, and camellia-like flowers in early summer.

Stewartia in autumn

    •Fothergilla (Fothergilla major) also earns its keep for much of the year, with bottlebrush clusters of fragrant, white flowers in spring and leaves that turn brilliant shades of yellow, orange and red in autumn.

    •Korean mountainash (Sorbus aucuparia) bears flat-topped clusters of white flowers in spring. In autumn, leaves take on a yellow color enriched with some brown and hints of red. Clusters of red fruits also ripen in fall. They’re small, but edible, a nice nibble.

    •Pawpaw (Asimina triloba) bears large leaves that have lost their summer-y, tropical look and have turned a clear yellow. The large fruits, also with tropical aspirations, have been ripe for a few weeks, with flavors akin to vanilla custard, banana, or crème brûlée. Take your pick.

NUTTY TIMES AND COLD WEATHER

/9 Comments/in , , , , , /by

Nuts Galore

    What a nutty time of year, literally! Chestnuts and black walnuts, two of my favorite nuts, were raining down, figuratively, just before the middle of the month.
    Black walnuts are free for the taking. Wild trees are everywhere around here, and keep increasing because of overlooked nuts buried by squirrels. The nuts are so abundant this year, and most years, that squirrels and humans can have their fill. (Not so with my filbert nuts; squirrels will strip those bushes clean.)
    Black walnuts have a strong flavor. Like dark beer, fresh blackcurrants, and okra, not everyone likes the flavor. That’s fine. Fast food chains might purvey foods that everyone sort of likes, while a home gardener and gatherer can grow and gather fruits and vegetable and nuts that he or she really, really likes, and ignore what he or she really, really does not like.
    There’s also, if you’re not a squirrel, the getting-to-the-nut problem with black walnuts. The first step is to remove it, as soon as possible after gathering the soft, messy, dark-staining husk. My wife, Deb, does this; I try and come up with contraptions to ease the job of husking 10 five-gallon buckets worth of nuts that eventually transmutes to 8 one-quart mason jars filled with nutmeats.
    We’ve gone through a few incarnations of huskers. One year I bought an old fashioned corn husker, which needed some modification with an angle grinder. It didn’t do the job. Another year I ran the tractor back and forth over the nuts in the driveway, a common method, but not effective enough.Various black walnut hullers
    In years past, Deb has given each nut a tap with a light sledge hammer, which is enough to loosen the husk so it can be easily twisted off. Another year, I mounted a flat piece of metal in a slot I cut in a short length of 2-by-4 wood. Rolling the nut over the metal edge was enough to make the husk easy to twist off.
    This year I drilled a nut-sized hole in a piece of wood and mounted it over a bucket. One whack with a light sledge hammer drove the nut through, minus the husk. Or, it was supposed to do that. One piece of husk, on the leading edge, alway stayed attached to the nut.
    So now Deb is back to one of the standard methods for de-husking black walnuts: Stomp on them with your heel, then pick them off to rub off any remaining husk.

Readying for Cold Weather

    Enough with the nuts . . .  tonight (October 10th) temperatures are predicted to be in the low 30s, which means the high 20s in this cold spot. Mostly, I and the garden are ready for cold. Still to be done are:
    •Close all hose spigots and open ends of drip emitters and main lines, watering wands, and hose sprayers to prevent the expansion of freezing water water from causing damage;row covered vegetables
    •Set up hoops and either clear plastic or row covers over beds of lettuce, Chinese cabbage, endive, arugula, and mustard greens. These vegetables tolerate temperatures well into the 20s, but I’ll cover them just in case. And they’ll anyway need the protective coverings soon;Row covered vegetables
    •Bring tropical plants indoors. Banana “trees,” staghorn fern, avocado, and clivia have laughed off cold so far, but tomorrow morning would not look so cheery if left outdoors. They get bright windows. A banana’s growing point is below ground which allows some gardeners to merely lop the whole top off the plant and store the bulb, in its pot, through winter under cool, dark conditions;Tropical plants indoors
    •Subtropical plants could survive temperatures into the 20s. I’m hoping for a crop from Golden Nugget mandarin, Meyer lemon, and Meiwa kumquat, so they’ve been walked indoors and perched near the most sun-washed windows in my house.
    •Feijoa, olive, and Chilean guava are, like citrus, evergreen, subtropical plants, except they can tolerate colder temperatures than citrus. They sport neither fruits, flowers, nor flower buds now, so will remain outdoors until temperatures dip into the low 20s. Potted rosemary is also in this category; because I will be visiting it many times over the months that follow to clip off sprigs clipped for pizza and salad dressing, it’s new home is a sunny kitchen window.
    •Basil will be dead tomorrow. Leafy stems picked today, their bottoms plunked into a glass of water, will provide fresh basil for a few weeks. Then it’s on to frozen basil pesto.

Cold Weather Takes a Rain Check, Without the Rain

    The Morning After: No drama. That’s the way I like it. The slider on my min-max thermometer registered a low of 29° last night. A far cry from my first gardens, in Wisconsin, where it seemed every year (for the five I gardened there) around September 21st I would be wake to a frigid morning and a garden of blackened tomato, marigold, and pepper plants. This morning, marigolds and peppers have felt the chill, but live on to die slowly day by day as the sun dips lower in the sky and temperatures creep lower and lower.

DUCKS AND TOMATOES

My Discerning Ducks

    Every morning when I throw open the door to my Duckingham Palace (a name coined by vegetable farmer Elliot Coleman, for his duck house), my four ducks step out, lower their heads as if to reduce air resistance, and race to the persimmon tree. They trace a large circle around the base of the tree, scooping up any fallen persimmons and, still running, gulping them down quickly enough so no other member of the brood snatches it.Duck eyeing my persimmon fruits
    The circle is wide because of the low, temporary fence I’ve set up around the tree. Within the fenced area, I gather up most of the fallen fruit for myself. The ducks, can’t, or haven’t figured out how to, fly over an 18 inch high fence.
    My tree is an American persimmon (Diospyros virginiana), native to eastern U.S. from Florida to northern Pennsylvania. Until they are dead ripe, most American persimmons taste awful, with an astringency that dries out your mouth. (As Captain John Smith, of Pocahontas fame, wrote, “When a persimmon is not ripe, it will draw a man’s mouth awrie with much torment.”) Some persimmons never lose that astringency, even when ripe, and here, in the northern reaches of persimmon growing, the season isn’t long enough to ripen most persimmons.Ducks not sharing persimmon fruits
    But good persimmons, when ripe, taste like dried apricots that have been soaked in water, dipped in honey, and given a dash of spice. Mine are selected varieties that ripen this far north, the first, Mohler, beginning in early September, and the second, Szukis, beginning in early October. (I grafted both varieties on one tree.) They also set fruit without the need for the separate male pollinator that most American persimmons require.
    I highly recommend planting an American persimmon tree. Besides bearing delicious fruit, the tree is attractive all season long and shows off its pretty bark in winter. All this, without the need for spraying or pruning. (I wrote about American persimmon in my book Uncommon Fruits for Every Garden.)Persimmon fruits on tree

And the Winning Tomatoes Are . . .

    As of this writing, tomato plants have not been killed by cold. But with cool weather and disease, they’re pretty much done for the season, bearing few or no fruits. That is, except for Sungold, the most tasty variety of cherry tomato. It just keeps pumping out ropes of orange fruits.
    I grew over 20 varieties of tomatoes this year, all heirlooms, except for Sungold. My main criterion for planting any variety is flavor, which was very similar for certain varieties of tomato. They did differ in productivity, my second criterion for choosing a variety. So next year I plan to pare down the number of varieties I grow to the best tasting, most productive ones.
    Topping that list will be San Marzano. Right off the plant, eating one is like eating bland cotton. Thrown into pot with a little water to prevent burning and simmered till soft, and the flavor morphs to tart, tomato-y richness. No wonder, canned San Marzano tomatoes are labeled as such in Italy.
    Moving on to fresh eating tomatoes . . . Sungold, of course, with eight plants supplying enough for grazing outdoors and salads indoors. Anna Russian, Paul Robeson, and Red Brandywine all have excellent flavor and bore well and late into the season. Anna Russian is also quite good for paste.
    Carmello and Valencia are good-tasting tomatoes, although not as good as Anna Russian and company. I’ll grow these two because they’re also very productive, and their fruits are almost perfect spheres. Many heirloom fruits are interesting for their convoluted shapes but sometimes I want just a standard issue, round tomato (that also tastes good).
    One more possible variety is from seed a reader sent me a few years ago, a variety labeled Winterkeeper. The fruits allegedly store very well. The plants are still growing well; soon I’ll see how long into fall I’ll be eating tomato sandwiches. Ones I’ve already sampled have pretty good flavor.

Persistent, Young, and Vigorous

    Every time I walk back to the compost bin and see the volunteer tomato vine insinuating itself out of a gap in the slats of the bin, I’m reminded of the importance of crop rotation. This vine is still lush and green, and laden with perfect, red, pear-shaped tomatoes.
    Sure, the vine could be healthy because its roots are running through the rich, brown compost within the bin. Perhaps the vine is so healthy because, as a random seedling, its genetics, by lucky chance, makes it so.
    Most likely, this plant is so healthy and productive because it’s growing where no tomato has grown before. No disease spores linger there from previous crops of tomatoes. (The plant got a late start for the season, so its youthful vigor could also have a hand in its health.) Compost pile tomato
    I rotate my tomato beds every year, but that only puts them 10 feet or so from beds of the previous year. That’s the problem with home gardens; it’s hard to get plants far enough away from where they recently were. Thorough cleanup and mulching help, but go only so far.
    I have the luxury of two vegetable gardens separated by 50 feet of lawn, one of which hasn’t been home to tomatoes for over a year. Next year it will be.
    The flavor of the compost-grown tomato? Good enough, not great.

    Digging a hole to bury an animal last week gave me new respect for the plant world. Each shovelful brought up dusty, light brown soil, even to a depth of more than two feet. That’s expected, since it hasn’t rained more than 1/4 of an inch here for the past five weeks.
    With their leaves flagging in midday, trees and shrubs don’t exactly look spry. Still, they are alive, even some spring-planted trees and shrubs which have had little time to spread their roots deep and wide.

    Appearance of a soil can be deceiving. There’s some water lurking within those pores, water held tightly by capillary attraction. After heavy rains or irrigation, all soil pores get filled with water, a situation as bad for plants, if it lasts too long, as dry soil. Plant roots need air as well as moisture; air gets sucked in once gravity drains water from the largest soil pores.
    From then on, capillary attraction is what holds moisture in the ground — a pleasant situation for plants because the roots can tap into the more loosely held capillary water while they breathe freely. I prepare for possible droughts when planting by digging relatively small planting holes, which minimizes the amount of ground loosened up, in turn, among other benefits, preserving capillary networks in the soil. (Mulching and watering, right after planting, also helps.)
    Eventually, more and more of the loosely held capillary moisture gets sucked out of the ground by plants and evaporation. At some point, there’s still moisture in the soil, but what’s left is in the smallest pores and right against soil particles. It’s tightly held capillary moisture, water that plants can’t access. They wilt. When moisture levels drop to what’s known as the “permanent wilting point,” plants die.
    We’re not there yet and now, toward the end of the season, woody plants do have a Plan B: They can just drop their leaves, reducing moisture loss from stems and roots, and segue into winter on stored energy and moisture. To a point.

Cold Air

    If it’s not one thing, weather-wise, it’s another. On September 26th, I woke to find parts of the lawn hoary with frost. I’m not complaining. Frost should be expected, on average, around that date around here. Except that I’ve been spoiled for the last few years by much later frosts, frosts, so late that I pulled out old tomato plants because chilly weather drained tomatoes of their flavor rather than frosty weather killing the plants.Endive, lettuce, and old tomato plants
    Also, no complaints because the September 26th brought only a light frost; temperatures just hit 32°F. and the hoariness was spotty, here and there. A light frost is a good thing this time of year. It signals plants to get ready for even colder weather. In preparing for cold, cell walls strengthen and permeability of cells to water is actively altered. Even subtropical plants like peppers and tomatoes toughen up, with some chilly preparation, so that they can now tolerate temperatures that drop even a few degrees below freezing.
    Tender vegetables, frost or no frost, on the wane, have left the door open to vegetables that enjoy the cool weather of autumn. Most of the garden now presents a verdant sight of beds lush with lettuce, Chinese cabbages, winter radishes, endive, turnips, cabbages, arugula, mustard greens, carrot tops, and leeks, all ready for harvest, at my leisure, over the next few weeks.

Fall Black Raspberries

    Segueing over to the fruit world, I’m still harvesting the last of the blackcaps (black raspberries) of the season. Blackcaps? Anyone familiar with this fruit, abundant in the wild and often cultivated, knows that they ripen in midsummer.

    Last year I planted two new varieties of blackcap, Niwot and Ohio’s Treasure. With most blackcaps, canes just grow their first year, then fruit their second year. (During the second year, new canes are also growing, to fruit the following year, so a planting bears fruit every year.) Niwot and Ohio’s Treasure bear fruit at the end of the canes’ first year of growth, in late summer and autumn. Those same canes — I think — then continue bearing the following year, in summer, just like most blackcaps.
    I haven’t yet decided whether Ohio’s Treasure or Niwot offer the better berry, but it’s nice to be harvesting fresh berries this late in the season.

DRY WOOD, & AUTUMNAL AIR

 Passionflower to the Rescue

   When I began, many years ago, to heat my home with wood, I struggled to get the driest possible wood, finally building a 60-foot long woodshed beneath which a double row of logs basked in the direct hit of sunlight from the south. I more recently learned that firewood can be too dry, which is when moisture drops below 15 to 20 percent. Bone dry wood can’t get enough oxygen for a clean, efficient burn, so smoke, within which is locked the potential for rendering additional heat, is produced; pump enough oxygen into the mix, though, and you get an inferno that can damage a woodstove.
    So — and here’s the plant-related part — rather than tear down or put siding on my super-drying woodshed, I put some heat loving vines to climb and provide some shade on the south face. Sections of hog-fencing temporarily hung on hooks just below the roof in front of each of the 8 foot bays support the vines.
    Maypop, Passiflora incarnata, is an ideal candidate for this location. (Learn more about maypop — a whole chapter’s worth! — Uncommon Fruits For Every Garden.) It’s an herbaceous perennial, emerging early each June to grow vigorously into lanky vines 10 or more feet long. Maypop is a hardy species of passionflower, and a few weeks after emerging, the intricate blue or white blossoms unfold along the stems.White maypop flower
    Flowers would be enough, but there’s more. A few weeks later, those flowers morph into egg-shaped fruits: tropical passionfruits this far north.Maypop fruit
    In southeastern U.S., maypop, with its spreading root system, is considered a weed. This far north, maypop will enjoy the extra heat of the microclimate at the south face of the woodshed. The woodshed itself will contain the plant in its travel northward. The lawnmower will contain the plant in is travel southward. Let it spread all it wants east and west along the base of the shed.

Morning Glory & Kin for Quicker Effect

    In spring I planted a maypop plant at the foot of four of the woodshed bays. As a perennial, maypop needs time to get established. Because I went to the trouble of hanging a trellis from each of the bays, I wanted something to clothe even this summer.
    Enter the Convolvulaceae family, which counts morning glory among its kin. Less know, but also kin and vines with pretty flowers, are cardinal vine and moonflower.  I figured that some member of this family could accompany maypop in each planting hole.Morning glory against woodshed
    All three Convolvulaceae family members grow vigorously so could provide good coverage for the woodshed. They also integrate well with each other, design-wise. Morning glory wakes up early, its sky-blue flowers opening each morning to foreshadow the blue sky that lies ahead. (The flowers remain furled under overcast skies.) Once the sun rises high in the sky, fire-engine red flowers of cardinal flower take the torch for the remainder of the day. As night falls, moonflowers’ large, white trumpets open and emit their sweet scent.
    This year, those annual vines grew so vigorously that they stunted their companion maypops. Next year will be better. Also, a couple of plants of another vine, native and somewhat decorative, have tried to get a foothold in the planting. Poison ivy, you’re not welcome here.

Autumnal Readiness

    Morning glories have started lingering later into the mornings, a sign that autumn is approaching. I’m also getting signals — a softness in the air and an occasional chill, a slight chill — of autumn’s approach. Those signals do not have me lingering late in the morning, though.
    The imminence of autumn has me scurrying around making sure all is copacetic in the weeks to come and on into next year. Turnips and winter radishes have been thinned. Cabbages, Chinese and European, transplants are growing well, hinting at crocks of kim-chi and sauerkraut to come. Onions have been harvested and woven into ropes for storage, now in the garage, later in the basement.Winter radishes and Chinese cabbages
    Any cleared vegetable bed is given a thorough weeding and then an icing of an inch depth of compost. That compost will snuff out small weeds attempting to sprout below. Additionally, it will feed soil microbes which will, in turn, feed plants for at least a year. I’ll sow arugula, mustard greens, and “spring” radishes in the bed which I recently cleared of sweet corn, weeded, and composted.
    A couple of sites have been prepared for two new trees. “Prepared” is too fancy a word; all I did was pile mulch on the ground at both locations. The mulch will kill existing vegetation and leave soft, moist ground for easy planting in October.
    Autumn will be bountiful and next year will be a good year.

PROXIMAL THOUGHTS, PROXIMAL ACTION

Easy Access Water

I am reminded today of the importance — in a home garden — of proximity. Proximity of the garden to a door or, even better, a kitchen door. Proximity of the compost pile to a door, to the garden, and, if bulky materials such as manure or wood chips are hauled in, to a driveway. And, the spur for today’s rambling, proximity of the garden to water spigots.Trench for water hydrant
    The saying that “April showers bring May flowers” notwithstanding, supplemental water is usually critical in my garden in April. Just a few days of sunny, balmy weather is enough to dry out the surface of the ground, just beneath which lie in waiting, for moisture, my newly sown seeds. Or recent transplants, whose roots have yet to venture out and down into the ground.
    Once roots from sprouting seeds and transplants start growing in earnest, they’ll encounter plenty of residual moisture still sitting in the soil from winter’s rain and snow. Until then, I either have to carry watering cans (two cans at two gallons each) back and forth from the frost-free spigot against my house to the garden, or haul around hoses. The cans are top of the line Haw’s galvanized with good balance; even so, hauling water can get tedious, and the tendency to skimp a little on watering is unavoidable.
    Fifteen years ago I installed a frost-free outdoor hydrant near my secondary vegetable garden. What a luxury! Problem is that to get water to the main vegetable garden I have to unwind a hose and thread it through the garden gate. And then, if temperatures drop below freezing at night, common in April, nothing can be done till ice in the hose has defrosted. Again, watering is too often inadequate because I’m avoiding all this hassle.
    (Hot temperatures, dry weather, and plants feverishly sucking moisture out of the soil present no problem during most of the growing season — now, for instance. A few times each day, an inexpensive timer automatically opens a valve to let water flow through tubes to each vegetable bed and then out specially designed emitters to drip water into the ground at about the rate at which plants are drinking it up. But this automated, drip irrigation system can be damaged if put into service when temperatures drop below freezing.)My new hydrant
    So today I’m digging tenches and holes for two new, frost-free hydrants to bring the source of water right next to the main vegetable garden and to my compost bins. In the future, I’ll have no excuse to skimp on watering.

Free “Fertilizer”

    Too may gardeners shove their gardens in a far corner of their property, as if the garden was an eyesore. (Which it often is.) I suggest locating the garden as close to the house as possible, given constraints of sunlight; six or more hours of summer sun, daily, is ideal. And make it ornamental, with fencing, a nice gate, and shrubs and flowers around and in it. Keeping it weeded also helps, as far as appearance and productivity.
    There’s an old saying that “The best fertilizer is the gardener’s shadow.” Make it so that shadow conveniently falls on not only the plants but also spigots and compost piles.

Celeriac, What’s Up?

    Insufficient water in April could not be blamed for the poor showing of my celeriac plants. They weren’t even in the ground until early May, after the drip irrigation was up and running.
    Celeriac is a nice addition to the variety of root crops that can be left in the garden until late into fall and then stored for the winter under cool, moist conditions. The flavor, which comes from the swollen root (actually a hypocotyl, which is the portion of the plant above the roots and below the stem), is akin to celery, but smoother. It’s a botanical variety of celery.

    Last year, the first time in years that I grew celeriac, plants were stunted with nothing to harvest. Last year, I set the plants in a narrow bed on the west edge of the garden next to a full bed of tall corn. I blamed my failure on shade.
    This year celeriac got a sunnier spot. Still, the plants are puny. Some of the plants share the bed with kale which has spread its large leaves to create more shade than expected. Celeriac, according to reputable sources, allegedly tolerates a bit of shade.

    My plan is to slide a trowel into the ground beneath some of the puniest plants, lift the plants out of the soil, and plop them into more spacious, sunny environs.
    Next year I’ll pay even closer attention to celeriac and expect a better harvest. (Then again, this season’s plants may be gathering energy, readying themselves to swell their hypocotyls as autumn draws near.) All part of next year’s even better vegetable garden, to which my new frost-free hydrant will be a serious contributor.
