NUTTY TIMES AND COLD WEATHER

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.

THE WEATHER, AND BLACKCAPS

Dry Soil

    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.

Niwot blackcap, now ripe

Niwot blackcap, now ripe

    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.

GOOD FOR CROPS, GOOD FOR THE EARTH

How to be a Good Gardener/Farmer, Simplified

    “The poor farmer grows weeds, the mediorcre farmer grows crops, the good farmer grows soil.” How true, when I think of the good farmers and gardeners I’ve visited over the years. I aspire to be a good farmdener and spend a lot of time trying to grow soil.
    Growing soil isn’t all that complicated. (You do need to start with good drainage of water.)
    First, keep the ground covered. Organic mulches, such as leaves, straw, and wood shavings, keep rain from pounding the surface. The pounding drives small soil particles into pores, sealing the soil surface so water can’t percolate in. Bacteria, fungi, worms, and other soil organisms gobble up organic mulches, releasing nutrients and forming humus, which improves percolation and moisture retention, and makes room also for air in the soil. In my gardens, I never want to see bare ground.Bare, cracked soil
    Live plants likewise protect the ground. The plants might be cabbages, marigolds, carrots, and other garden plants. They might be cover crops, such as rye, oats, peas, or buckwheat, sown specifically to clothe and protect the ground during or at the end of the growing season, and through winter. They might even be weeds — Mother Nature’s way of protecting her soil.
    Second, maintain soil organic matter. Mulches do this, as do growing plants. I go one step further, and import organic matter. Bushel after bushel of leaves that have been raked and bagged by neighbors are collected are unbagged and unraked once they arrive here. Leaves that have been vacuumed into a landscaper’s large truck and then left here in a pile get unpiled here one pitchfork and garden cart at a time.
    I also pitchfork horse manure into the bed of my pickup truck at a local stable. Mostly, that manure is transmuted into compost and then slathered onto beds in the vegetable garden.

Compost, in the making

Compost, in the making

    I also import — really just transfer — some organic material from one part of my property to another. My small hayfield gets mowed once a year by tractor to keep it from becoming forest but parts of it I periodically scythe, these mowings to feed, along with the horse manure (and kitchen waste, old garden plants, etc.), compost piles.
    The third key to growing soil is to maintain fertility. A soil test can confirm what, if anything, is needed. If the first and second points in growing soil are followed, fertility is probably up to snuff.
    And finally, the fourth key to growing soil: Minimize soil disturbance, avoiding tillage or, at least, excessive tillage. Tillage mixes so much oxygen into the ground that soil organisms go into a feeding frenzy, in so doing gobbling up organic matter too fast. Thus, many of the above benefits, physical, biological, and nutritional, waft away, literally, as carbon dioxide.
    Farming and gardening aren’t “natural.” At their best, they are a balancing act that leans towards emulating natural systems. Which is to say, for instance, that tillage, is not all bad; it can be part of good soil growing if not done to excess and points one, two, and three are followed.
    A measure of “organic matter content” (OMC), from a soil test, provides a rough indication of soil growing progress. Less than 3% means more work is needed. Five percent, or more, is very good. (My vegetable beds are at about 15%.)

Blue-Green Algae Redux

    Last week’s notes about the darker side — and the brighter side — of blue-green algae may have left everyone feeling helpless. After all, you can’t change the hot dry weather that is, in part, responsible for the current blooms. But nitrogen, phosphorus, and other minerals washing into waterways to feed the bacteria also play a role, and it’s something over which we have control.
    Improper septic systems are one culprit.
    More topical culprits are mineral nutrients originating in backyards and farm fields. Too many farmers and homeowners subscribe to the philosophy that “if a little is good, more is better,” when it comes to fertilizer. Not so. Too much fertilizer not only is a waste of money; it damages or kills plants and, with rain, leaches through or runs off the soil to eventually find its way into waterways. A soil test will tell what nutrients, if any, are needed.
    Even better, if fertilizer is needed, is to use an organic fertilizer. Most are not water soluble until metabolized by soil organisms, which means they are less likely to wash through the soil.
    Better still would be to use compost to provide fertility. Nutrients in compost are locked up physically and chemically, waiting to be released by soil life in synch with plant uptake and growth.

     Phosphorus is a plant nutrient that binds tightly to soil granules, but makes its way downhill when rain washes over bare soil to move it downslope. One way to keep this nutrient out of waterways is to keep the soil covered with mulch or vegetation, especially on sloping land. Another way is to avoid exposing soil by tillage. Another way, if tillage is needed, is to till perpendicularly to the fall line of a slope. And yet another way is to alternate tilled areas with grassy strips to catch and hold soil.

Rye cover crop

    Do a lot of these recommendations — mulches, cover crops, composts, no-till — for preventing blue-green algae blooms sound familiar? Good gardening and farming practices are also good for the environment.

FRUIT HARVEST, WHEN?

/7 Comments/in , , /by

Easy to Grow, Hard to Harvest

    Of all commonly grown tree fruits, pears are the easiest, mostly because they succumb to fewer pest and weather problems than do other common tree fruits. Of all commonly grown tree fruits, pears are the most difficult to harvest.
    Timing is what makes pears so difficult to harvest, a skill I’m ashamed to admit I have yet to master. You can’t time when to pick by taste because pears are among the few fruits that will not ripen well on the tree. They start ripening from their innards outward so by the time the outside of the fruit looks and feels ripe, the innards are brown mush.

Concorde European pear, ripe?

Concorde European pear, ripe?

    No need to refer me to the guidelines of experts: The skin should undergo an almost imperceptible change in color, lightening or yellowing. The fruit softens ever so slightly, going from the firmness of a basketball to that of a softball. The fruit stalk separates readily from the stem when the fruit is lifted and given a slight twist. And finally, in my opinion the most obtuse indicator, lenticels (small pores on the skin) change from white and raised to brown and shallow. Yadda, yadda, yadda, . . .
    I grow about 20 varieties of pear, and each of those very subtle indicators are slightly different for one variety to the next.
    Another of my excuses is that most of my varieties are just beginning to bear so I don’t have a lot of fruits from each tree to play around with. I am adept at harvesting those varieties — Magness, Seckel, Harrow Delight — that have borne the most fruit for the most years.

Easy to Grow, Easy to Harvest

    Ah, but my horticultural shortcomings don’t extend to all pears. I also grow a few varieties of Asian pears, which differ from the aforementioned and more common European pears in being usually round and of a few different species. Most significantly, Asian pears will ripen to perfection on the tree. In fact, for best flavor, they must remain hanging until dead ripe, at which point they have a “cracking” texture, that is, they are crisp but explode in your mouth with their sweet, ambrosial juice.

Yoinashi Asian pear

Yoinashi Asian pear

    The skin of Chojuro, the earliest of my Asian pears, started changing from brown russet to golden yellow russet earlier this month. As a further check to ripeness, I picked a fruit and sunk my teeth into it. Delicious! They’re ripe and hang in good condition to be plucked from the branches, as needed, for a week or two, or they can be harvested in toto and refrigerated. The varieties Yoinashi and Seuri Li will follow shortly here, with Korean Giant following these two varieties next year, when it comes into bearing.
    Asian pears are as easy, perhaps even easier, to grow than European pears. They bear at a young age and heavily, often too young and too heavily, which is why it’s necessary to grit your teeth and aggressively thin the fruits. Too heavy a crop stunts young trees or spells small, less flavorful fruits on grown trees. (I devote a whole chapter to Asian pears in my book Uncommon Fruits for Every Garden.)

And Then There are Grapes

    Grapes . . . they’re easy to harvest ripe. Except that most people don’t. Color is but one indicator that a bunch wants to be harvested and eaten (that is, after all, fruits’ raison d’être). But like some other fruits — blueberries, for example — grapes turn their ripe color before they are dead ripe.

Cocord grape

Concord grape

    So I also pull off a berry or two to taste. The difference in flavor between just ripe and dead ripe is dramatic. And especially so with my bagged grapes, which can segue to the dramatic stage within their bags without threat of predation by birds and bees.
    The variety Concord presents an exception to that last statement; birds don’t like the flavor and leave the berries alone. This means the berries don’t have puncture holes that attract bees and wasps, so they also are not a problem. The deterrent in Concord grapes is the chemical methyl anthranilate, which has been formulated as a spray to keep birds at bay. My wife also doesn’t like Concord.

SOME REFLECTIONS. . . NOT THAT IT’S OVER

/2 Comments/in , , /by

Finish Squash

    “Zucchini bread is for people who don’t have compost piles.” That’s what I told Deb after she suggested, first ratatouille, and then zucchini bread, as vehicles for our excess zucchini.
    Most years I make an early, too large planting of zucchini (about 6 plants), and then, six to eight weeks later, make another sowing of only a couple of plants. The first planting puts enough zucchinis into the freezer for winter, as well as leaving enough for eating. The second planting is to yield an occasional zucchini for fresh eating through summer after plants of that initial planting have succumbed to squash vine borer, cucumber beetles, bacterial wilt, and any of the other maladies that usually do in the plants a few weeks after they begin bearing. Usually and thankfully do in the plants. But not this year.
    Almost every time I check that early planting of zucchini, a new fruit has swelled at the end of a vine now trailing beyond its bed beneath stalks of popcorn in an adjacent bed. I feel no obligation to eat zucchini, whether in zucchini bread, ratatouille, or any other concoction.

Where Are the Insects?

    In all my decades of gardening, I’ve never experienced a season with so few insect pests. A few Japanese beetles reared their ugly heads back in July; they were the only ones who showed up, except for an occasional straggler. Likewise for bean beetles. Eggplants hosted the few requisite flea beetles, but never enough for concern. (I did spray a few times with horticultural oil; judging from other gardeners’ flea beetle-less experiences this year, doubt that the effect was from the oil.)
    Cabbageworms, always requiring some late summer action on my part in the past in the form of one or two sprays of the biological insecticide Bacillus thurengiensis, have let me occupy that time with other things.
    Spotted wing drosophila, known non-affectionately as SWD, showed up, as usual, in sufficient numbers in early August to warrant a spray of spinosad, an extract from a naturally-occuring bacteria found in the soil of a defunct rum factory in the Virgin Islands. That one spray, along with some experimental traps from Cornell, was sufficient to keep the buggers from using my blueberries as nurseries in which to raise their young.
    As is so often the case with complex systems, in this case involving the vagaries of this season’s weather, the biology and the chemical and physical make-up of the soil, interactions between garden plants as well as between garden plants and weeds, timing of plantings . . .  what I’m trying to say is that I have no idea why the year was so auspicious, as far as insects.

Here Are the Diseases

    That was insects. Diseases are another story. Don’t look at my tomato plants.
    The tomato plants started the season neatly and decoratively trained as single stems up bamboo poles, soon clothing those poles in lush, green leaves and red or orange tomatoes. Now? Stems are pretty much bare from ground level up a couple of feet, with some shriveled, brown remnants of leaves dangling downwards. The disease is not fusarium or verticillium, to which so many modern tomato varieties are touted for being resistant.Diseased tomato plants
    The affliction is leaf spot disease, which is actually one or more of three diseases: early blight, septoria leaf spot, and/or late blight. The worst of the three is late blight, which makes us gardeners and farmers especially nervous after a severe outbreak ravaged a large swath of the Northeast a few years ago. Air currents and humidity have not been favorable this year for late blight to hitchhike up from the South, where it overwinters, and any that might have reached here couldn’t get footholds with this season’s hot, dry weather.
    Thorough cleanup of old leaves and stems, which house early blight and septoria leaf spot through the winter, and planting tomatoes where they haven’t been plant for the previous two years, was supposed to keep these diseases in check. Perhaps it did, but not enough.
    I have two vegetable gardens, and next year I’ll plant tomatoes in the one that housed no tomatoes for the past couple of years, putting more distance between overwintering disease spores and my plants. Clean up and distance should also quell one other disease, anthracnose, responsible for sunken, rotting areas that develop on some of the fruits.
    Diseases notwithstanding, plenty of glass jars filled either with sparkling red, canned tomatoes and dull red, dried tomatoes line shelves to bring some essence of summer into through the dark months ahead.

Pepper Heaven

    Tomatoes may be the essence of summer for their ubiquity in gardens; for me, though, ripe, red peppers more represent a summery flavor. My peppers rarely experience insect or disease problems. The challenge, this far north, is ripe, red peppers in abundance.

Italian Sweet peppers

Italian Sweet peppers

    My favorite variety for flavor, earliness, and productivity, especially this far north, is Italian Sweet. I put in many plants this past spring, and the harvest is prolific.
    Unfortunately, dried or frozen peppers offer only wan hints of the fresh peppers’ summery flavor and texture.

The River Runs Green

    Crossing the bridge over the Wallkill River on my way home, I glance to my right to admire the river itself. What a beautiful color it has turned, a bright turquoise. Ponds I pass also have taken on this bright complexion, for which we can thank, or curse, organisms known as blue-green algae (heretofore referred to as BGA).
    Algae, they are not, though. BGA are bacteria known as cyanobacteria. “Algae” generally refers to eukaryotes, organisms with distinct nucleii and specialized organelles. BGA are prokaryotes, lacking such features.Green river, from cyanobacteria
    BGA can be toxic, which is good reason to curse them. Drinking or swimming in contaminated waters can cause problems to humans and other animals, including dogs, who seem to be otherwise able to drink almost any water without ill effect. The “cyan” in the name and the criminal cyanotoxins are not at all related to cyanide. The name come from “cyan,” which is the color blue-green.
    Many kinds of BGA are found throughout the world, often in extreme conditions. Not all produce cyanotoxins; some produce them only under certain conditions. Not all are even blue-green; the Red Sea gets its color from Trichodesmium erythraeum, a species of BGA. Certain conditions cause “blooms,” such as those I was admiring in the river and ponds. Here, it’s probably a combination of relatively dry conditions resulting in shallow and calm waters along with the usual influx of nutrients, mostly phosphorus and mostly from farms, septic systems, and lawns.
    BGA are photosynthetic organisms, just like plants, imbibing carbon dioxide during the day and spewing out oxygen. These primitive organisms, “in the beginning,” were important for oxygenizing the Earth’s atmosphere, thus stimulating biodiversity. We could praise them for sequestering carbon.
    Agriculturally, some cyanobacteria are important because they can convert atmospheric nitrogen into forms of nitrogen that plants can use. Although these cyanobacteria are especially important for maintaining fertility of rice paddies, they are present, to some degree, in virtually all soils. Some research even points to benefits of inoculating soils with these organisms.

Bags vs. Fungi

    So now I’m home, my head out of the soil, and admiring my grape vines. The dry weather has been almost as good for the grapes as it has been for the cyanobacteria. Dry weather minimizes grape diseases and abundant sunlight puts flavor and sweetness into the berries. With annual applications of mulch around the grapes and their far reaching roots, I never worry about my established vines being thirsty.Bagging grapes earlier in the season
    Back in early summer, we went to the trouble of affixing paper “delicatessen” bags around 100 bunches. Now is the payoff. Peeling back the paper usually reveals perfect, full, bloom-dusted bunches of especially delectable grapes. “Especially delectable” because I can let these protected bunches hang longer on the vines than unbagged bunches, which do have some disease and are prey to bees, wasps, and birds. These bagged grapes get dead ripe before being harvested.Unbagging grapes for harvest
    The bagging isn’t really all that troublesome. We just select downward hanging bunches, made easier because I train fruiting canes horizontally across a 5-wire, flat trellis, and remove any tendrils or leaves opposite the bunches. After making a slit down each side of a bag, the slitted opening is slid up the cane on either side of the bunch, the top of the bag is folded over, and then the flap stapled down on either side —  well worth the minute or so it takes from selection to finish bagging a bunch.

Grapes to Keep

    With many varieties of established grapevines, I can cut down any whose flavor is not up to snuff or that don’t produce well without having to bemoan waiting for new ones to start bearing. The “keepers” tide me over.  Variety choice is somewhat limited here because of winter cold and because cooler, damp air collects in this valley, promoting disease, abetted by inoculum from all the wild grape vines grappling high into neighboring trees along the forest edge.

    I’ll be doing a Henry IVth on Mars and Concord.
    Some of my current favorite varieties are Vanessa, Somerset Seedless, and Glenora, all seedless varieties. Of the three, Glenora has the best flavor, Vanessa the best texture, but they’re all very good. Some of my favorite seeded varieties are Alden, whose corpulent berries hang in large bunches, and Brianna, which isn’t quite ripe yet, but every year has rewarded us with foxy-flavored, pale green berries.
    Still to come for this season are Edelweiss, which has a rich, very foxy flavor but has not been very productive the last few years, and Brianna, with its own rich flavor not so dependent on foxiness.
    A few more years of tasting and watching will dictate whether New York Muscat, Cayuga White, Bertille Seyve 2758, Lorelei, Reliance, Swenson White, and Wapanuka keep their home here. They’re all good grapes, but why grow good grapes when I could grow great grapes from among the 5,000 or so varieties (not all adaptable here, of course)?
    (That “foxy” flavor I kept referring to is characteristic of many American grapes, and is typified by the variety Concord. No one is sure how “foxy came to describe that flavor.)

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.

UNPERMACULTURE

/0 Comments/in , , , , , /by

Accusations,  (Mostly) not True

I’ve understandably been accused of being a “permie,” that is, of practicing permaculture.
    (In the words of permaculture founder, Bill Mollison, “Permaculture is about designing sustainable human settlements. It is a philosophy and an approach to land use which weaves together microclimate, annual and perennial plants, animals, soils, water management, and human needs into intricately connected, productive communities.” In the words of www.dictionary.com, permaculture is “a system of cultivation intended to maintain permanent agriculture or horticulture by relying on renewable resources and a self-sustaining ecosystem.”)
    Walk around my farmden and, yes, you’ll come upon Nanking cherry bushes where forsythia bushes once lined the driveway, an American persimmon tree where a lilac bush once stood, and other edible plants used also for landscaping. In the vegetable garden, I preserve soil integrity by never tilling it, and, in the south field, blackcurrant bushes make use of the space beneath pawpaw trees. There’s the requisite mushroom yard of shiitake-inoculated logs, free-range poultry, solar panels, a rain barrel . . .

Pawpaws interplanted with blackcurrants, and a row of hardy kiwis

    But no! I am not a permie. My vegetables grow in beds in parallel, straight rows (rather than keyhole plantings) and, despite that commingling of blackcurrants and pawpaws, most trees, shrubs, and vines here keep to themselves. Permaculture plantings of, say, hazelnuts in tall grass and rubbing elbows with elderberries, seaberries, apples, pears, and other edibles become, over time, an unproductive management nightmare with some plants drowning out others, productivity declining due to shade, and diseases increasing from tangled stems creating dank conditions. The paltry output of such planting are best left for wildlife, who can afford to spend all day foraging for a few tidbits of food.
    My hazelnuts are grown in a mown strip that, for easy gathering, is sheared low as nuts ripen.
    Low maintenance is a goal touted by permaculturalists; understandably so. But taken to the extreme, low maintenance means not giving the grape vine the pruning it needs to be a healthy vine yielding the most flavorful berries that are easy to harvest. (One book suggests, rather than troubling with a trellis, growing grape vines up trees; the vines do so in the wild, but such fruit, in partial shade and not easily accessible, can never be high quality.)
    Much of permaculture seems to me to be not only unrealistic, but also no fun. I enjoy caring for my plants, reaping the gustatory and other rewards for a job well done. I like the challenge of researching some pest or nutritional problem and finding a solution. I like watching how plants respond to my ministrations, whether I’m wielding pruning shears, a pitchfork piled high with compost, or my winged weeder hoe.
    Agriculture is about balancing Nature’s designs and human will. Too much of the latter is a losing battle. Too much of the former leaves nothing worth harvesting.

Big Bantam, an Oymoron

    My planting of sweet corn is very un-permaculture. It’s high-culture: 6 seeds per hill dropped into compost-enriched ground maintained weed-free, timely watering with drip irrigation, hills thinned to 3 stalks per hill, even stakes to keep the stalks standing soldier straight. I mentioned, last week, how my Golden Bantam variety of sweet corn isn’t bantam at all. The stalks soar over 10 feet high.
    Was it because of my green thumb? No. I now know that it is genetics.
    This year I made four plantings of Golden Bantam. The two later plantings are, in fact, bantam-size. Looking over my seed orders, I see that I had planted Golden Bantam Corn, Original 8-row Golden Bantam Corn, and Improved Golden Bantam Corn.
    Golden Bantam is an open-pollinated variety. As with any open-pollinated variety, various strains might arise, strains which might differ in some ways from the original. With any good variety, the hope is that progeny are monitored to eliminate any off-type varieties — or to look for something that might be better than the original.

    So the name Golden Bantam could be attached to the original Golden Bantam, from 1902, or any strain, which could also have “Improved,” “Original,” etc. attached its name. (Golden Bantam was also developed into a hybrid, Golden Cross Bantam, which, like other hybrids, would be genetically more consistent and ripen in a shorter window of time.)
    On the theory that bigger is better, “Improved” was tacked onto name of the strain of my early plantings. The original Golden Bantam was 8-row; Improved Golden Bantam is 10 to 14 row. I should have read the catalog more closely because Improved Golden Bantam casts too much shade, ripens too late for my intensively planted vegetables, and yields less, with but a single ear per stalk. The original also has better flavor, to me.

Permaculture, but not by Me

    Walking down the main path of my vegetable garden yesterday, you’d come upon a very permaculturalesque planting — in the path. The path was overrun with purslane, which I didn’t even have to plant. Purslane is a tasty, very nutritious vegetable enjoyed raw or cooked. But not by me.Hoeing purslane in path
    I grabbed my winged weeder and hoed the purslane loose from the soil. As a succulent, purslane can continue to grow — and seed! — even with its roots flailing in the air. So after hoeing, I scooped the plants up to feed to the compost file.

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.
