WHAT’S UP WITH THE LEAVES?

No Other Explanation

The leaf-goblin struck again; this time I was sure. Leaf season is pretty much over around here but I was in my car on my way to do some errands and spotted a row of plastic trash bags full of leaves lined up along the other side of the street. I says to m’self, “I’ll be back this way within the hour, so I’ll stop and throw the bags in the back of the truck on my way home.” When I drove by again, the leaf bags were gone! This was not an isolated incident, but never has the leaf-goblin’s handiwork been so quick.Cat on leafy mulch

I suppose I’m to blame for this curse. Over the years, I have written about, spoken about, yes, even bragged about all the leaves — that’s other people’s leaves, conveniently in bags — that I have gathered up each autumn for my garden. I have preached to anyone who would listen about the folly of stuffing leaves into plastic garbage bags to be thrown out. Read more

UBER ORGANIC & A BEAUTIFUL BLOSSOM

‘Tis the Season

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

Organic Matters

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

A Beaut’ Worth Reviving for Winter

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

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

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

Who’s the Best Gardener/Farmdener?

Fresh Watermelon, and More, with Help from Ethylene

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

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

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

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

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

The Watermelon Mystery

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

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

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

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

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

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

Deb & Ethylene Take Credit for the Peppers

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

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

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

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