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.

A VERY GOOD YEAR, SO FAR

Bye, Bye Beetles

    So far, this growing season has been one of the most interesting ever. Could it be global warming? Perhaps. Perhaps it’s all a legacy from the relatively snowless winter with long periods of cold, but not frigid, temperatures. Perhaps it was spring’s two nights of plummeting temperature that followed a warm spell. Perhaps it was this summers extremes of dry and wet periods. Perhaps all that’s from global warming. Perhaps . . .
    All I know is that it’s all been pretty good. As I wrote previously, for the second year in a row, Japanese beetles made their entrance on time in June, and then, as if from stage fright, skittered away. Or never emerged from the soil. Or never hatched from eggs laid in the soil. Or the eggs never got laid last summer.
    For years, Mexican bean beetles would lay eggs on my bean plants, and those eggs would hatch into voracious larvae and then adults that would shred bean leaves. I was able to harvest enough beans for fresh eating and freezing only with succession planting of bush beans every couple of months.Mexican bean beetle
    For the past couple of years, only a few beetles show up here and there; nothing to worry about. So now an early sowing of bush beans provides the first plates of beans, and then passes the torch on to pole beans, which unlike bush beans, keep yielding till the end of the season. Bush beans peter out after a few pickings.
    (I did spray neem oil and the biological insecticide ‘Entrust’ a few years ago. Perhaps that broke the Mexican bean beetle cycle here. Perhaps it was the mere threat of a wall at the Mexican border . . . No, no, that can’t be it. Mexican bean beetles have established themselves north of the border for many generations, human and beetle. Throughout the country over many decades, this pest has waxed and waned in its severity, at times turning its taste to soybeans, sometimes to lima beans. My beetles never showed an appetite for my soybeans.)
    Two other pests that, I hope, can now be off my radar are scale insects on the greenhouse figs and flea beetles on the eggplants. That status comes with some effort on my part: weekly sprays, until recently, of “summer oil.” I expect to have to maintain those efforts every season. (Late update: I saw a few scale insects on the figs so did have to spray again.)

Skyrocketing Corn, De-Luscious Blueberries

    This season’s interests aren’t all about pests.
    Right now, corn stalks are as high — no, higher — than an elephant’s eye. (For journalistic accuracy, I looked up the height of an elephant’s eye. One report on the web, that fount of highly accurate information, reported the median height at 98 inches.) I just stepped away from my desk to measure the actual height of my corn, and it topped out at about 10 feet high. And that’s the variety Golden Bantam. I’ve grown it for many years, during which it always topped out at 6 or 7 feet.
    The first ears of this rich-tasting, old variety should be ready any day now. Will they also seem to be on steroids?Tall Golden Bantam corn
    No explanations for this corny behavior jump out. Year after year, the soil gets the same one-inch depth of compost, the 3-foot-wide corn bed is planted in two rows of hills, thinned to 3 stalks per hill, with each hill 2 feet apart in the row, and the bed is drip irrigated. Mislabeled seed can’t explain the phenomenon because this season’s popcorn (Dutch Buttered and Pearl) and polenta corn (Otto File) also have higher aspirations. Anyway, I’m not complaining.
    Apples never grow well here. This low lying valley is a sink for colder, moister air that, along with the backdrop of thousands of acres of forest, is a haven for apple pests. This season, with some spray assistance from me, the apple crop is relatively heavy and attractive. Apples, in those years when I do get a decent crop, are especially tasty here.Blueberry fruit cluster
    I have to tip my hat, once again, to blueberries, my favorite fruit and the most consistent performer among my many fruits. I have never not gotten a good crop of blueberries, come hell or high . . . 17 year cicadas, hurricane Irene, late frosts, etc. This season, canes are arching to the ground with a particularly heavy crop of berries.
    What will next year hold? An even better growing season?

GOOD FRUITS, ONE A VEGETABLE

World’s Best Fruit?

    Finally, I reap the fruits of one of my labors. Literally. The fruit is black mulberry, the species, that is Morus nigra, rather than any of the black-colored mulberries that grow all over the place around here. The latter are species and natural hybrids of white and red mulberries (M. alba and M. rubra).
    Black mulberry, native to the Mediterranean climate of western Asia, is not cold-hardy below temperatures in the ‘teens (Fahrenheit) so definitely not cold-hardy here. I first tasted it at a fruit conference in Davis, California and it wowed me even from among bowls heaped high with fresh-picked apricots, peaches, and other seasonal fruits.
    I had to get a tree to grow, which I did (from www.whitmanfarms.com). The tree went into a pot with potting soil. As it grew, I moved it on into larger and larger pots, stopping at an 18-inch diameter pot. I figured that would be the largest pot I could muscle down the basement steps for cool, winter storage along with my figs and pomegranates.
    The tree bore quickly, and the “east coast” black mulberries were delicious, what few of them I harvested. Problem was that birds also found them delicious, a problem compounded by the fact that the berries are not at their best until matte black and ready to be released from the plant at the slightest touch. The birds don’t wait that long.
    Dead ripe, the fruits are so soft that they can’t help but stain your fingers. (The stain was once used as a dye, called “murry.”)

A Cagey Solution

    My first solution to the bird issue was to plant the mulberry in the ground in my cool (as in temperature cool) greenhouse, which is also home to some in-ground fig trees. Since mulberry seedlings pop up all over the place around here, I just dug up a seedling, grafted onto it a stem from my black mulberry, and planted it in the greenhouse.Fruit cage
    Mulberry trees can grow big, bigger than my greenhouse. My plan was to espalier the branches against the west wall of the greenhouse. The espalier worked as far as training the branches in an ornamental candelabra. The birds were kept at bay. The espalier did not work as far as bearing fruit, the reason for which I have no idea why. I dug up the tree.
    My original mulberry still grows in a pot and, despite its small stature, still bears good crops of fruit. A few weeks ago I saw advertised a walk-in, temporary cage for protecting plants from birds (available from Gardeners Supply Co.).
    The cage arrived just as the first black mulberries were ripening. Within 20 minutes I had the various pole pieces joined to each other and to the corner brackets, and the net attached over the top and sides. At 4 feet by 4 feet and 6 feet high, the cage easily accommodates my mulberry. Even another plant or two.
    Every couple of days, now, I unzip the door, enter mulberry paradise, and carefully peruse the plant for dead-ripe berries. I exit with purple-stained fingers. Success.

Eggplant + Oil, A Good Combo

    Another success this year has been eggplant. I’ve gardened for many, many years, and for many, many years wasn’t able to grow eggplants well. Beginning gardeners are the ones who usually have greatest success with eggplant. Not exactly beginning gardeners, but beginning gardens.Eggplant plantEggplant, flea beetle damage
    Flea beetles love to eat eggplant (leaves). They pock the leaves with enough small holes so that only vigorously growing plants survive. But flea beetles rarely show up in a garden in its first year but by the second year they descend in hoards. Hence the successes of beginning gardeners in their beginning gardens.
    This year I tried controlling the beetles by spraying the plants weekly with “horticultural oil,” also called “summer oil,” which is a more refined and lighter version of “dormant oil.” I was mixing it up anyway to keep scale insects at bay on the greenhouse figs (more on that some other time). Long story short: The plants are only slight hole-y and I have a fine crop of eggplants on the way.   

TWO DELICIOUS ORBS, ONE BLUE & ONE WHITE

/2 Comments/in , , /by

Soil is Key

    Last week I described my foray into the New Jersey Pine Barrens, culminating in a visit to the USDA research station there to experience many new, interesting, and tasty varieties of blueberry. The soils of the Pine Barrens, as I wrote provide ideal conditions for the rather specific and unique requirements of this fruit.
    That’s not to say that blueberries can’t be grown successfully beyond the Pine Barrens. In fact, they can be grown just about everywhere — if the right varieties are chosen and the soil is amended to suit the plants. The soil here at my farmden, for instance, is very different from that of the Pine Barrens. Mine is a naturally rich silt loam that is slightly acidic; the Pine Barrens are naturally poor sands that are very acidic.
    Both soils are well-drained, which is the first requirement for a blueberry soil. The way to make soils that are less than perfectly drained suitable is to plant the bushes atop mounds or carry water away in ditches or in buried, perforated pipes.
    Next, acidity. The pH for blueberries needs to be between 4 and 5.5, which is very acidic (and is what blueberry relatives such as rhododendrons and mountain laurels also demand). I acidifed my soil with elemental sulfur, a naturally mined mineral, before planting and do so periodically over the years, as needed. Many gardeners pile oak leaves or pine needles on their ground, or dig these materials into soil, to make a soil more acidic — that doesn’t do the trick; sulfur is what’s needed, 3/4 to 2 pounds per hundred square feet for sandy and clay soils, respectively, for each unit of pH change needed.Netted, healthy blueberries
    Blueberries like their roots coursing through soils that are high in organic materials, not rich organic materials such as manure or compost, though. Peat moss is good; I mixed a bucket full of peat with the soil in each planting hole when I planted. To maintain, even increase, levels of organic matter over the years, the ground beneath my bushes, every year, gets blanketed with a 3 inch depth of some weed-free organic material, such as autumn leaves, wood chips, wood shavings, sawdust, pine needles . . . whatever I can get my hands on.
    And finally, blueberries need water, especially when young. That initial dose of peat moss along with yearly, organic mulches, helps the soil hold moisture (in addition to many other benefits).
    Oh, one more thing: Ninety percent of blueberry roots are in the top 6 inches of soil. Hence their need for moisture. Those shallow roots also compete poorly with weeds. My 900 square foot of 16 blueberry plants is, essentially, a “no weed” zone, thanks to the mulch and occasional weeding.

Tastiest Turnips

    Pushing open the gate to exit the blueberry planting, I walk over and pull open the gate to the vegetable garden. There lies a beautiful (to me) row of sweet, succulent turnips. Not just any old turnip, but the variety Hakurei, the best (to me, and many others gardeners and farmers).
    Turnips are an underrated vegetable, perhaps because most that you can buy just don’t taste that good and because most that are grown in home gardens are not the best-flavored. The highest praise I know of for turnips is in the novel Tobacco Road, when Lov Bensey walks seven and a half miles to get a sack of winter turnips for fifty cents, which is half of his daily wage. (Admittedly, he was starving.)
    So here’s at least the second written accolade for the turnip. When a good variety is planted and it is well grown, it is a sweet, flavorful vegetable excellent raw, pickled, or cooked. The variety to grow is Hakurei and the way to grow them is in rich, well-drained soil with a steady supply of moisture, the latter of which mine get automatically via drip irrigation.

Hakurei turnip

Hakurei turnip

    In the past I planted turnips only in late summer for a crop that ripened during the cool weather of autumn. This year I planted an early crop in the greenhouse; that crop was harvested and eaten by mid-June. I had plenty of seed and space in later in spring, so I planted some outdoors then. We’re still harvesting that crop and, despite the hot days, the flavor is excellent. (Cool nights might be helping to maintain flavor.)
    Sometime in the next two weeks, I plan to sow seeds for fall harvest. Last year, that crop, harvested before the weather turned too bitterly cold and the soil froze, went into wooden boxes for cold storage, first just sitting outdoors, then carried into the garage, and, finally, carried down to the cool basement. The last of them, still tasty, were eaten March.

SUMMER WEATHER, PLANT THE GREENHOUSE

/10 Comments/in , , , /by

 Ginger on the Way

   Now that summer-y weather has blown in and is here to stay, it’s time to plant the greenhouse. Plant the greenhouse?! This time of year? Yes. No reason to let all that real estate go to waste through summer.
    Ginger plants that I started from supermarket tubers a couple of months ago were crying out to be released from the confines of their 4-inch pots. Warming their bottoms on the seed-starting heating mat pushed them along even when early spring skies were overcast and the greenhouse relatively cool. Ginger is a tropical plant that shivers even when temperatures drop below 55°F.Planting ginger
    I never could see the rationale for the current interest in growing ginger in northern regions. That is, until I tasted freshly harvested, baby ginger. This far north, ginger rarely has time to develop the mature, tan-skinned roots you see in supermarkets. No matter, because immature, or “baby,” ginger, which is ginger harvested before it matures, is better — a white, tender, tasty tuber. It doesn’t keep or ship as well as mature ginger, which is no problem for backyard growing or local sales.
    So 4 ginger plants went into two greenhouse beds. I’ll dig up the ginger in September, freeing up space for lettuce, celery, kale, and other cool weather salad makings that will inhabit the winter greenhouse.

Early Curcurbits

    One can eat only just so much ginger. (We’re still using last year’s harvest which, for long term storage, was sliced thin and put into jars with vinegar.) What about other greenhouse beds that are being vacated as the last of winter’s lettuce, celery, kale, and chard get harvested and cleared away?
 Greenhouse in June   Cucumbers and melons love heat, so a few extra plants that I started back in early May went into beds.
    The permanent fixtures in the greenhouse, the plants that really help the greenhouse earn its keep, are the four fig trees — Bethlehem Black, San Piero, Brown Turkey, and Rabbi Samuel — planted right in the ground. The largest of these has a trunk 7 inches in diameter. All yield bountiful crops daily in August and September, and less bountiful ones going into October.Figs growing, last of greenhouse lettuces

Tropicals and Subtropicals Summer Vacation

    In a reversal of fall, tropical and subtropical plants that had been moved into the greenhouse and house are now lined up outdoors, ready to offer fresh black mulberries, Pakistan mulberries, pineapple guavas, pomegranates, Golden Nugget mandarins, olives, dwarf Cavendish bananas (probably no fruit from this one, just a very tropical look), and a few other varieties of figs, in pots.
    (My black mulberry is the species Morus nigra, one of the best-tasting of all fruits, but is not cold hardy here. Black-colored mulberries that grow all over the place outdoors here are, despite black fruits, species of red or white mulberries, or their hybrids.)
    Any of my tropical and subtropical plants, given their druthers, would reach 8 feet, 10 feet, or even more feet skyward, and spread their roots many feet in all directions. Here, they can’t do that or they would be too big to move or to house in winter.
    So I mixed up a batch of potting soil, and started root pruning. It sounds brutal, and it is, but plants recover nicely and then happily have new soil to explore. Basically, I slide a plant out of its pot, stand it upright, and then start slicing off the outer edges of the root ball. Pruning shears take care of any roots too large to slice with a knife.
    The finished root ball is an inch or two smaller in diameter than it started out. How much to remove depends on the initial size of the root ball — larger plants get more removed — and, to a lesser degree, the kind of plant. Figs, for instance, tolerate especially brutal treatment.
 Root pruning   So much for the roots. To keep it manageable, the plant also needs stem reduction. Some stems get shortened, some are removed in toto, and some are left untouched. Who gets what treatment depends, for fruiting plants, on their fruiting habit — just where and how they bear fruit. Figs that bear on new shoots can be pruned rather severely; pineapple guavas bear on new shoots growing off older stems, so only moderate pruning is tolerated so that some older stems are preserved, etc.
    After root and shoot pruning a thorough watering, plants are ready for a year or two of good growth before they will again feel constrained.

WINTER’S LEGACY, STILL

/2 Comments/in , , /by

Half a Pear, Tree

   Perhaps last winter’s weather — extended cold, but not frigid temperatures, and hardly any snow — is still playing games with us. Perhaps it is mischief from the early, extended, very warm weather in early spring that was followed by plummeting temperatures and our biggest snowfall (4 inches) of the year. Whatever the reason, some weird things are going on this growing season.Half dead pear tree
    Look at one of my old pear trees, for instance. This tree might be called my “sample” or my “first cut” pear tree. When I hear tell of a pear variety that might be worth growing, I get a scion and graft it onto this tree. The scion bears quickly, in theory, at least, and, if it passes the “first cut,” perhaps it will warrant its own tree. There’s not enough time or space to put every Tom, Dick, and Harry of a pear variety on its own tree.
    The tree now has about a dozen varieties of pear growing off various branches. That’s not weird, though. What is weird is that, right now, the top half of the tree is fully leafed out while limbs on the bottom half of the tree are leafless.
    A disease? Doubtful. A disease killing that much of a tree at once would probably originate in the trunk or roots, in which case the whole tree or only the upper portion would be leafless. And anyway, those leafless limbs are not dead. Cutting beneath the bark reveals living, green tissue.
    My hypothesis — a weak one — is that the cold snap in spring, where temperatures in the ‘teens followed a spate of temperatures in the 70’s, is the culprit. Warm temperatures in late winter and spring cause plants to rapidly awaken and lose the cold-hardiness they maintained through the coldest parts of winter. The pears seemed quite awake when that cold spell struck.
    But why was only the bottom portion of the tree affected? (Here’s the weakness in my hypothesis.) Windless, clear nights, such as during spring’s cold snap, bring a temperature inversion. Under such conditions, denser cold air can settle down near ground level. Even a few feet of elevation can make a difference, one that’s evident when riding a bicycle or motorcycle on a clear summer night on rolling terrain.
    So maybe the bottom half of the pear tree experienced temperatures just below the tipping point where enough damage occurred to delay leafing out.

Other Pear Trees, Still Whole

    No other plants, including other pear trees, experienced this bifurcation. Then again, the “sample” pear is all by itself where the microclimate might be slightly different.
    During that cold snap, the other pears were quite awake, seemingly just about ready to spread their blossoms. I was braced for a total crop loss. Weirdly, the trees went on to blossom just fine and now have what’s shaping up to be a decent load of fruit on them.

Seedling Troubles

    More weirdness: Every season I sow vegetable seeds according to a schedule I’ve developed over the years. I sow the seeds in mini-furrows in flats of potting soil or potting soil topped with a mix of peat moss and perlite. Every season I make my own potting soil from a mix of equal parts peat moss, perlite, compost, and garden soil, with everything sifted together through half-inch mesh hardware cloth.
 Sickly tomato seedlings   And every season I’ve had sturdy, lush green transplants to set out over the past few weeks. Not this season. Too many of the transplants are stunted, with flaccid leaves that are not uniformly lush green. Some have slight, interveinal yellowing of oldest leaves, some have slight reddening of veins, hinting, respectively, at insufficient nitrogen and phosphorus uptake .
    As usual, the weather could be blamed. Those auspicious, sunny days of late winter gave way to a long period of overcast days. Rain or not is not the issue because seedlings were in the greenhouse, watered as needed. Overwatered? Underwatered? Cool greenhouse temperatures could limit root growth, in turn limiting uptake of nutrients even if they are in the soil.
    The potting soil could be the culprit. Although ingredients of my mix are always proportionately the same, the compost isn’t exactly the same from year to year. Same goes for the “garden soil” that goes into the mix. I scrape it up from various places around the yard: the bottom of a finished compost bin, from my catch-all extra soil bin, from top layers of a pond I’m occasionally hand-digging.
    A couple of other gardeners and farmers have concurred with their seedlings’ poor growth this year. Perhaps it was the weather? Do you want to weigh in?

And the Winner Is . . .

    Very few people offered hypotheses on why only one limb of my plum tree was in bloom. Neither the weather nor any other environmental condition was to blame. In fact, I had grafted the tree a few years ago to four different varieties in order to spread out the harvest date and offer a greater variety of plum flavors.Plum, blossoming branch
    The bulk of the tree had already flowered.The one blooming branch was that of beach plum, the least reliable, smallest, and, to my taste, least flavorful of the lot. Perhaps I’ll graft that limb over to yet another variety.
    Congratulations to Tom, tkjazzer@gmail.com, on winning a copy of my book Grow Fruit Naturally.

RATIONALITY CHALLENGED

/4 Comments/in , , , /by

New York Avocadoes!?!?

    I make no claim to be rational in my gardening — especially this time of year. This thought comes to mind as I look closely at two avocado plants sitting in a sunny window. “Nothing irrational about growing avocado plants in New York,” you might say. After all, the large seeds are fun and easy to sprout, and the resulting plant adds some tropical greenery indoors.
    My two plants were run-of-the-mill avocado houseplants until I took knife to them.
    Let’s backtrack . . . Among my regrets of not living 1,000 miles or so south of here is not being able to harvest my own citrus and avocados. (Also, no outdoor gardenia shrubs or southern magnolia trees here.) A few indoor citrus plants do call mi casa sus casa. But no avocados.Avocado grafts
    From seed, an avocado would take a long time before it bore its first fruit. And especially long under less-that-ideal northern conditions, including indoors in winter.
    And worse, when the plant does finally flower, it might not bear fruit. Avocados generally need cross-pollination because the pollen isn’t ripe at the same time that the female stigma is receptive. Avocado pollinators need to be fairly specific, so that one plant’s pollen is in synch with another plant’s stigmas.
    And even worse, after all that time and hoping for appropriate mates, fruits that do form might not taste good. They wouldn’t be selected clones, such as the delectable Haas or Mexicola, but seedlings. (Plant a seed from a good tasting apple and the resulting tree has only one in 10,000 chance of bearing a good-tasting fruit.)
    Which is why I took a knife to my two avocado seedlings, to graft them to known, good-tasting varieties that are pollination compatible. A friend in Florida overnighted me scions — pencil-thick stems, with leaves stripped — cut from his Marcus Pinkham and Lula avocado trees. One of my seedlings got a whip graft of Marcus Pinkham; the other got a side-veneer graft of Lulu.
    I coverWithed both grafts with plastic to maintain humidity, and every day peer at the scions hoping to see some swelling in preparation for growth.
    Rational gardening? No. After all, even if all goes as planned, how many avocados could I expect to harvest from two small trees? Still, it’s fun.

Warm. Plant.

    Outdoors, it’s the weather that toys with my rationality. A spate of warm days and great restraint is needed not to plant vegetables. I keep referring to my notes (and the chart I made in my book Weedless Gardening) that tell me when to plant what.
  Planting onions  With yesterday’s 75 degree temperatures, urges to plant were satisfied — for that day, at least — by my poking holes into the ground into which I dropped onion plants sown indoors on February 1st. Three-hundred of them in a 20 foot long by 36 inch wide bed. (This was later than the April 21st onion planting date specified in my book, but the weather was cold so I forgot to look at my book.)

Planting Break. Turn Compost.

    When I get tired of planting, I can always turn to turning my compost piles.
    Not that compost piles have to be turned. In contrast to other fermentations, such as bread-making and wine-making, compost always comes out right. Pile up any mix of organic (living or once-living) materials, and eventually you get compost.
    I turn my compost piles so that materials on the outside of the pile get to be on the inside of the pile, second time around. This makes for a more homogeneous finished product.Turning compost
    I turn my compost piles to better monitor their progress, so adjustments can be made, as needed, and to get some idea when they’ll be ready for use. Occasionally, a pile will have a dry region; it gets watered. Occasionally, a mass of material needs to be broken up to better expose it to moisture and microorganisms.
    I also turn my compost piles because it’s good exercise and it’s interesting. But, like I wrote, turning a compost pile is not a must.

IT’S ALL ABOUT THE WEATHER

Snow!!

    The talk of the town these days is the weather. In this town, at least, and other towns throughout the Northeast. After a relatively snowless winter punctuated with warm spells, spring knocked early at winter’s door and was let in. Even I, who try to be guided by the calendar rather than my gut, succumbed, planting peas a full two weeks earlier than my usual date of April 1st. Flowering trees and bushes — and more importantly, those whose flowers later morph into luscious fruits — similarly fell prey to spring weather’s apparent arrival.
    As I write, snowflakes tumble down from a gray sky, adding to the three inches of snow already piled onto spring green grass. Temperatures tonight and tomorrow night are predicted to drop near 20 degrees F. We’ve all been duped!!

Nanking cherry flowers with snow

Nanking cherry flowers with snow

    I’m most concerned, and least able to do anything about, weather’s effect on my fruit trees and bushes. Nanking cherries were in full bloom a few days ago, a full two weeks earlier than average. Asian pear flower buds look about to pop open, blueberry buds have fattened in preparation for opening , and black currants and gooseberries have almost fully leafed out.
    Options available to commercial orchards are not feasible in backyards. Such as sprinkling plants with water so that the heat of fusion released as water freezes keeps buds warm; you can’t stop sprinkling until weather warms enough to melt all ice. On clear, cold nights, heavier, cold air sinks but can be warmed by mixing in warm air from higher up. Not many backyard gardeners have wind machines or are willing to have a helicopter hover overhead all night pushing down warmer air.
    What we backyard growers can do that orchardists cannot, feasibly, is to snug a few small plants — bushes and dwarf trees — beneath a blanket. (Except that I have a lot more than a few small fruit plants.) That’s about it. Besides keeping fingers crossed and hoping for the best.

Winter Cold!!

Peach flower buds, dead

Peach flower buds, dead

   Peaches are famous for their early blossoming, so I was especially worried for them. My peach tree spent its first few years in a large pot which could be conveniently lugged into the garage whenever cold weather threatened its blossoms.
    No need to worry this year. I checked the fat, flower buds, and they are already dead. Winter’s cold and/or fluctuating temperatures evidently had already done them in.

(Too) Early Peas

    My early planted peas took advantage of the last couple of weeks of balmy weather and sprouted quickly. Temperatures near 20° will surely freeze those sprouts. They might resprout from protected buds below ground, or not.
    I nudged ol’ man winter aside and created a warmer microclimate over the sprouts by putting up metal hoops covered with row covers over them. They may have been better off with the blanket of snow tucked all around them. Then again, the snow cover might settle too much, or blow away.
    In a few days, I’ll see how the peas fared. Worst case scenario: replant.

Not Climate Change

    “Climate change” is the battle cry for this whacky weather. But is it really so whacky?
    As far as the cold, the average date for the last killing frost of spring in my garden is around the third week in May. The key word here is “average.” Looking at a tabulation of percent chance of cold temperatures on various spring dates (davesgarden.com), on average there’s a 50% chance of the thermometer hitting 24° on April 14th around here, a 10% chance on April 27th.

    “Frost” means 32°F. For that magic 32°, which is lethal to tomato and pepper seedlings but of no consequence to cabbage and onion transplants, there’s a 50% chance of that temperature on May 13th, even a 10% chance on May 27th.
    Of course, temperatures in my (or your) garden could be a few degrees different from those at nearby weather stations, which supply those averages. Still, looking back at my own records, while last year Nanking cherries blossomed here on May 2nd in 1999, they blossomed on April 18th in 2004, on April 26th in 2012, and on March 29th in 2015.
    So it seems like whacky weather is the norm. Except this year, it does still seem that the early warming was slightly earlier, and the later cold — 15°F, now, the day after the snowfall — more intense. Then again, Nanking cherries have never failed me.

FAILURES, SUCCESSES

Can Anybody Tell Me How to Grow This?

     Quotes about the rosy side of failure are not hard to find. ”Failure is the opportunity to begin again more intelligently,” wrote Henry Ford. John Dewey wrote that “Failure is instructive. The person who really thinks learns quite as much from his failures as from his successes.”
    No, Mr. Dewey; in gardening, at least, failures are more instructive than successes. Put a seed into the ground and that seed has millions of years of evolution prompting it to grow. True, you can fail if starting with old seed, or soil so cold that the seed rots before it grows, or compacted clay soil that suffocates the seed. But generally, gardening is not that difficult. And generally, it’s hard to fail. So success is the norm, no matter — within reason — what you do.

Jasmine -- no flowers, again

Jasmine — no flowers, again

    For someone who pays particular attention to their gardening (and writes about it!), occasional failures are surely opportunities for learning and for success. Not so, for me! With my jasmine (Jasminium officinale) plant, at least.
    I’ve grown this jasmine for many years. In its early years, the plant was a snowball of sweet-smelling white blossoms in late winter. Over the years, flower production has petered out, to the point where the plant coughs forths just a few blossoms here and there.
    Many plants need a cold period to induce flower buds. Over the years, my jasmine has spent fall outdoors or in my cold basement (near a window) or in my cold greenhouse (minimum temperature 37°F).
    Many plants need a dry period to coax on flower buds. Over the years, the soil in which my jasmine grows has been kept through fall just moist enough to keep the plant from wilting.
    Some plants need a period of both cold and dryness for flowering. Check.
    Besides all these treatments, I have tried various suggestions from others, including professionals who sell jasmine plants awash in bloom from their commercial greenhouses. No pruning after August. No artificial light in autumn. Generally good growing conditions all through summer. High phosphorus fertilizer. Check. Check. Check. Mmm-check. (I’ll admit I neglected the high phosphorus fertilizer. With ample compost, my potting soil has ample phosphorus, or so I assume.)
    Now, in its thirteenth year here, jasmine has again not bloomed. I’ve learned nothing. Again, I’m threatening to walk it to the compost pile, counterbalanced by inklings of desire to give it one more try. (The phosphorus fertilizer, perhaps.)
    My one possible consolation comes from reading a quote by George Bernard Shaw, “My reputation grows with every failure.”

Cardoon Futures

Cardoon I saw in Oregon

    Enough self-flagellation. Let’s balance that out with a couple of successes, one the result of my doing, not driven by millions of years of evolution.
    I’ve written previously about cardoon, a so-so vegetable but a fine ornamental. (True, many other people sing passionate gustatory praise for cardoon.) As a perennial, cardoon grows only leaves its first year from seed, which is fine if your eating it, because the leaf stalks are the edible part. The tall, spiny, olive green stalks, like a Mediterranean celery on steroids, also are dramatically ornamental in their own right.
    The flowers, poised like cerulean bottlebrushes atop their tall — five feet high, or more — flower stalks are the real show, though. And, in that second year and beyond, you still get the whorls of giant leafstalks rising up from around the base of the plant.
    Cardoon can’t tolerate winter cold below about 10 or 15°F, so it’s not winter cold-hardy here.  Too much moisture around the crown of the plant might also help do it in during winter.
    Last fall, after cold had settled into the ground, with about an inch depth of frost in the soil (towards the end of December) I cut back the top of the plant, then piled dry leaves over it. An overturned, 2-foot-diameter, plastic planter over the leaves kept them in place and added a bit more insulation and, also important, kept rain and snowfall off the plant. The drainage holes around the bottom (now the top) of the planter’s side allowed for some air movement within.
    A week or so ago I tipped off the planter and untucked the leaves from around the plant. It was important to get to the plant before warmth got it growing, in which case the once-shaded, tender leaves would burn in the sunlight and be susceptible to frost. The leaves, just starting to emerge from the decapitated plant, looked healthy and ready to stretch out and grow after their winter’s rest. I look forward to the flowers.

Really Red Deer Tongue

    Winter lettuce in the greenhouse is my other success. While many lettuces have begun to go to seed, especially those sown earlier in fall, the variety Really Red Deer Tongue just keeps making new leaves in spite of it’s having been sown in early September of last year. The leaves, as the names says, are red and, I suppose, the shape of a deer’s tongue. I don’t normally eat deer tongues, but these leaves taste good.Lettuce, Really Red Deer Tongue

THE WEATHER CALLS THE SHOTS

The Kindest Cuts

    In years past, when I went outdoors this time of year, it was usually with skis strapped to my feet. Or wearing snow boots. Or snowshoes. With this snowless, warm winter, I’m mostly going outdoors these days armed with pruning shears, a lopper, and a pruning saw. Mostly, my feet trod a path to the hardy kiwifruit vines and the blueberry bushes.
    At first glance, the blueberries seem nothing more than a jumbled mass of stems of various ages. How to make order out of this jumble? Quicker to answer is why go to the trouble of making order out of this jumble. The same could be asked for my lilac bush, mockorange, hazelnuts, gooseberries, and currants.

    Then I remind myself that my goal is to reduce the crop — yes! reduce the potential crop — so that more of the each fruit or nut bush’s resources get channeled into fewer fruits or nuts so those that remain taste better. I also prune for future years’ harvests or, for flowering bushes, future years’ flowers. And I prune to let the stems of all bushes bathe in light and air, which reduces pest problems.
    Bushes are bushes because they are bushy, that is, they’re constantly growing new stems at or near ground level and never develop permanent trunks. (Except for daphne, fothergilla, witch hazel, PeeGee hydrangea, tree peony, and other plants of bushy stature with long-lived stems.) Blueberries and most other bushes, ornamental and fruiting, are pruned by a renewal method. As stems age, they grow decrepit, producing less flowers or fruits; pruning away these oldsters, right to the ground makes way for younger, replacement stems.

3 Steps, and Blueberries are Pruned

    My first cuts on any of my blueberry bushes are the most dramatic ones: I cut down a couple or so of the oldest stems using a lopper or pruning saw. Blueberry stems are typically worth keeping until they are about 7 years old, or about an inch in diameter. These most dramatic cuts also remove the tallest stems in one fell swoop, so the bushes never grow so tall that the berries are out of reach.
     The kind of shrub, the variety of shrub, and the previous season’s growing conditions all conspire to determine how many new stems, called suckers, grow from or near ground level. Often, it’s so many that as they mature, the bush becomes congested. So now I take pruning shears in hand, and reduce their numbers to, in the case of blueberry bushes, four or five.

The finished bush then — in theory — has about 4 six-year-old stems, 4 five-year-old stems, and so on, down to 4 one-year-old stems. By this time next year, each of those stems will have moved up a year in age. I’ll remove the 4 now seven-year-old stems and excess one-year-old stems, which are those that will have grown this season.
    Oh, one more step: I go over each bush with my pruning shears, removing small or dead twigs and shortening stems that are out of bounds. With 16 bushes cramped into 900 square feet, “out of bounds” is pretty close.

Early Cukes, One the Way

    As so often happens in late winter and early spring, and especially this year, weather is very variable. Today was sunny and, by winter standards, balmy — perfect for crawling in among the blueberry bushes to prune them. But no need to twiddle my thumbs on sunless days raw with cold. There are seeds to be sown.
    Some people spend the first part of summer hankering to bite into their first ripe tomato. Even more than tomato, I eagerly await my first fresh cucumbers and peppers. Like tomatoes, both get a head start indoors.Cucumber seedlings
    This year, after seeing the very early cucumber crop at Evolutionary Organics farm down the road from me, I thought I would give early cukes a try here at the farmden. On Kira, the farmer’s advice, I planted seeds a couple of weeks ago into potting soil in 4” plastic flower pots.
    Cucumbers revel in heat, both for seed germination and for growing. So, after being watered, the seeded pots went onto the greenhouse’s electrically heated seed mat that’ll keep the seeds at a cozy 80°F. Seedlings are up, their roots still still in pots and still being warmed by the heating mat.
    Within a couple of weeks, the cuke seedlings will start to outgrow their pots and need planting in the ground  — not outdoors, though, but in the greenhouse. As I wrote, I’m hankering for a very early harvest. I’ll take the soil temperature which, I hope, will stay steadily above 65°F by then.
