SNOW’S COME AND SO HAS FRUIT
Free and Attractive Mulch
Beautiful. Floating down from the sky. A white blanket of “poor man’s manure.” That’s what gardeners and farmers have called snow.
In fact, snow does take some nitrogen from the air and bring it down to ground level for plant use in spring. Not that much, though. Just a few shovelfuls of real manure could supply the same amount of nitrogen as a blanket of snow.
Mostly, what I like about the 15 inch deep fluffy whiteness now on the ground is the way it insulates what’s beneath it. Fluctuating winter temperatures wreak havoc on plants, coaxing them awake and asleep and awake and asleep as air temperatures go up and down and up and down. Each time plants are awakened, they become more susceptible to subsequent cold, the whole problem exacerbated with borderline hardy plants.
Anticipating cold weather and snow, last fall I cut back a cardoon plant and two artichoke plants, covered each with a large, upturned plastic planter, and then smothered everything in autumn leaves. 
Both kinds of plants are probably cold-hardy to about zero degrees Fahrenheit, but here winter temperatures, except last winter, typically drop to about minus 20 decrees Fahrenheit. That snowy blanket provides extra protection that the plants might need — especially after last Saturday’s unseasonal low of minus 8 degrees.
Hardy orange (Citrus trifoliata) is another plant to benefit from snow cover. It’s a Citrus that’s allegedly cold-hardy into zone 5 (-20°F minimum temperature). I planted some seeds outdoors a few years ago and, while their roots survive winter cold, the tops die back to resprout each spring. I also planted out a more mature hardy orange that was given to me; it also suffered some cold damage.
The deeper this winter’s snow and the longer it stays deep, the more of the hardy oranges’ stems will survive till spring. Perhaps, helped along with global warming, enough of the above ground parts of the plants will survive to reward me one year with sweet-smelling blossoms and, less appealing, their very puckery fruits.
Multiplying Currants and Grapes
Last fall, I cut stems from my black currants and grapes into 8 inch lengths. In the bare ground between some dwarf apple trees, I scratched some lines and pushed a straight-bladed shovel into the ground on that line. Levering the handle of the shovel opened up just enough space in which to shove one or two of those cut stems, distal ends up, right up to their topmost buds. Then I moved along the scratched line, pushed the shovel in again, shoved in more stems, and so on down each line. If all goes well, each of those stems will grow into a good sized plant that I can dig up and transplant next autumn.
That is, unless alternating freezing and thawing of the soil heaves those stems up and out of the ground. I’ve seen it happen, leaving a row of carefully inserted stems sitting on top of the ground by winter’s end.
All of which is another reason I’m thankful for the snow. In addition to protecting plants from cold, the blanket modulates soil temperatures, keeping cold soil cold, which is how I’d like it to remain until spring. I could have — should have — thrown some fluffy, organic mulch, such as leaves or straw, over the stems to do the same thing. But I didn’t. I hope the snow stays.
Where One Plus One Does Not Equal Two, Figuratively Speaking
The harvest has begun: I picked the first fruit of the season this week. Not only that, but it was the first fruit I harvested from the particular plant. The fruit was a Sunquat, planted in a pot a year and a half ago. It summers outdoors and winters indoors, basking in sunlight streaming through a south-facing window.
Not many people have heard of Sunquats. I hadn’t. Citrus plants hybridize freely and Sunquat is one of many citrus hybrids, this one a mating of kumquat (Citrus japonica) and Meyer lemon. I happen to be a big fan of the tart flesh and spicy, sweet skins of kumquat fruits. I also happen to be a big fan of Meyer lemon, which is not a true lemon but is probably a hybrid of lemon and sweet orange.
Meyer lemons are juicy and somewhat sweet, with a flowery aroma. They also bear prolifically. As testimonial to their precocity, I once had a cutting that flowered soon after rooting, when it was only a few inches tall.
So what could be bad about combining kumquat and Meyer lemon? A Sunquat! The skin was sour without picking up any of the spicy tang of a kumquat’s skin. The flesh was much less puckery than kumquat or lemon, but was uninteresting, just bland. Perhaps harvesting a bit underripe, before the skins turn full yellow, will put some pizazz in a Sunquat.
If not, I’ll stick to growing Meyer lemons and kumquats, each on their own and with their own delectable flavor.
CLOSING “SHOP”
Chips, Not Hay, In This Case
“Make hay while the sun shines.” Good advice, literally in agriculture and figuratively in life. And I’m following it these days, in agriculture. Not making hay of course, because that sunshine is only effective in summer and fall, partnered with heat.
The “hay that I’m making” is actually mulch that I’m spreading. A few weeks ago I put my “WOOD CHIPS WANTED” sign out along the road in front of my house. In a short time, an arborist was kind enough deposit a truckload of chips. 
I figured I could spread it on the ground beneath some of my trees and shrubs, especially the youngest ones. There, next summer, the mulch would keep weeds at bay, slow evaporation of water from the ground, and feed soil life, in so doing enriching the soil with nutrients and organic matter.
Usually, by this time of year, my piles of wood chips have frozen solid or are white mounds beneath snowy blankets. Not so this year.
So I’ve been loading up garden cart after garden cart with chips to haul over to the garden. (Once the ground disappears beneath a heavy, white layer of snow, moving heavy cartloads becomes nearly impossible.)
Since the most important trees and shrubs had already been mulched earlier in autumn, I decided it was a good time to add a layer of chips to the paths in the vegetable garden.
Chips there are mostly to suppress weeds which thrived with last season’s unusually abundant rainfall and to soften, by spreading out, the impact of footfall on the paths. I generally “chip the paths” every couple of years at a minimum if for nothing more so that the height of the paths keeps up with the rising height of the vegetable beds which get — and already got, at the end of this season — a one-inch deep blanket of compost annually. (Besides the usual benefits of mulches, the compost provides enough nutrients for the intensively planted vegetables for the whole season. No fertilizer per se is needed.)
After decades of my adding an inch or more of wood chips to the paths and compost to the beds, you might suppose that the whole vegetable garden has risen a few feet above the surrounding area like a giant stage. Nope. The goodness of organic materials, such as the compost and wood chips, comes from soil organisms chewing them up and breaking them down. As decomposition takes place, the bulk of these materials, which are mostly carbon, hydrogen, and oxygen, is released into the air as carbon dioxide and water. The minerals that remain feed the plants.
Pine Berries?
One bed in the vegetable garden is home to strawberries. That bed also needs mulching, for different reasons and with different materials than the other beds, and needs it every year about now.
A strawberry plant is mostly nothing more than a stem, a stem whose distance from leaf to leaf has been telescoped down to create a stubby plant. 
Like the stems of any other plant, a strawberry stem each year grows longer from its tip and also grows side shoots. So a strawberry stem rises ever so slowly higher up out of the soil each year.
Strawberry stems are not super cold-hardy. As a stem slowly rises higher in the ground, it’s exposed to more and more cold, and more apt to dry out.
What’s needed is to protect the stems with an insulating blanket of some loose organic material. Straw is traditional — and one possible root of the name “strawberry” — but good straw reliably free of weed seeds is hard to find. Instead of straw, I often use wood shavings, conveniently available in bagged bales. This year I decided that the giant pine tree here could spare a few pine needles, raked up to share with the strawberries.
The goal of mulching strawberries isn’t to keep cold out, just to moderate the bitterest cold. 
Mulching too early might cause the stems to rot. I typically wait until the ground has frozen about an inch deep which usually occurs towards the end of December here, and then cover the plants with about an inch depth of wood shavings.
Come spring, the mulch needs to be pulled back before the plants start growing. Tucking the mulch in among the plants provides the usual benefits of mulch, especially important for strawberries because of their shallow roots, and provides a nice, clean bed on which the ripening berries can lie.
(More about growing strawberries can be found in my book GROW FRUIT NATURALLY.)
Hey, Good Looking
I admire the look of my vegetable gardens this time of year. With the chipped paths and compost lathered beds, some also with a tan cover of winter-killed oat plants, they look very tidy and ready to welcome new seeds and transplants in the months ahead. The look doesn’t compare with the lush greenery and colorful fruits of the summer garden, all of which is nothing more than a memory.
FINAL HARVESTS
Compressed Gardening Experience
People are so ready to sit at the feet of any long-time gardener to glean words of wisdom. I roll my eyes. Someone who has gardened for ten, twenty, even more years might make the same mistakes every year for that number of years. I, for instance, swung a scythe wrong for 20 years; I may have it right now. Even a wizened gardener who has evaluated and corrected their mistakes has garnered experience only on their own plot of land; these experience may not apply to the differing soils, climates, and resources of other sites.
When I began gardening, my agricultural knowledge and experience was nil, zip, niets, rien, nada. But — and this is important — I had easy access to a whole university library devoted solely to agriculture. Hungry to learn, I read a lot. (I also was taking classes in agriculture.) In one year I was able to garner years of, if not actual experience, much of the knowledge that comes with that experience. And my garden showed it.
I’ve now gardened many decades and still gobble up the written word.
All of which is to say that reading reputable sources about gardening can make anyone a much better gardener and do so quicker than by gardening alone. “Reputable” is a key word in the previous sentence. So here’s the, to use the phrase of Magliozzi brothers on the radio show Cartalk, Shameless Commerce Division of this blog: a plug for my books. I stand firmly by anything I’ve written and am open to criticism.
Here’s the book list, all available from the usual sources or, signed, from me through this website (good gift idea, also):
•A Northeast Gardener’s Year: A month by month romp through all things garden-wise, what to do, how to do it, and when to do it.
•The Pruning Book: Plant responses, pruning tools, how to prune just about every plant (indoor, outdoor), and final sections on specialized pruning techniques, such as scything and espalier.
•Weedless Gardening: A four-part system, emulating Mother Nature and based on current agricultural research, that makes for less weeds and healthier plants, along with other benefits such as more efficient use of water and conservation of humus.
•Landscaping with Fruit: Following introductory chapters about designing your landscape is a listing of the best fruits to use for “luscious landscaping” in various regions and how to grow each of these fruiting trees, shrubs, vines, and groundcovers.
•Grow Fruit Naturally: Describes multi-faceted approaches to growing fruits without resorting to toxic sprays, starting with selecting kinds of fruits and varieties and moving on to encouraging natural predators, beefing up the soil, and more.
•The Ever Curious Gardener: Using a Little Natural Science for a Much Better Garden: Knowing some of the science behind what’s going on in the garden can make you an even better gardener; here’s how.
Vegetable Finale
And now, on to some gardening . . .
I’ve said it before and Yogi Berra said it before me, “It ain’t over till it’s over.” Last night’s temperature plummeting to 18°F was still not enough to put the brakes on the vegetable garden. Beneath their covered “tunnels,” arugula, mustard, endive, and napa Chinese cabbage still thrive. Along with mâche and kale, which aren’t under cover, all these greens are looking as perky as ever and, most important, taste better than ever.
Interestingly, temperatures I’ve measured within the tunnels are not that different — actually, not different at all — from temperatures I’ve measured outdoors. But something’s different. The increased humidity under the tunnels is probably at least partially responsible for the fresh tastes and appearances.
It’s a wonder that these tender, succulent leaves tolerate such temperatures. You’d think the liquid in their cells would freeze and burst the contents to smithereens. That would have been the case if the 18°F had come on suddenly, without any precedents.
Plants aren’t passive players in the garden. Increasingly cold weather and shortening days acclimated these plants to cold. (A month ago, temperatures dropped one night to 16°F.) Plants move water in and out of their cells, as needed, to avoid freezing injury. And increasing concentrations of dissolved minerals and sugars in the cells make the water freeze at lower temperatures. Perhaps that’s one reason why these vegetables taste so good. The tunnels also slow down swings in temperature, giving plants time to move water in and out of their cells and whatever else they do preparing for and recovering from cold.
Too many people, even gardeners(!), consider endive as nothing more than a bitter, green leaf best used as garnish. Reconsider. Given close spacing so that inner leaves of each head blanche from low light along with cool and cold temperatures, and endive takes on a wonderful, rich flavor. 
Only the slightest hint of bitterness remains, enough to make the taste more lively — delicious in salads, soups, and sandwiches.
Fruit Finale
The last fruits of the season, Szukis American persimmon, were harvested last week after over a month of eating them. Definitely the easiest fruit I grow. No pruning, no pest control. And definitely one of the tastiest: imagine a dried apricot soaked in water, dipped in honey, then given a dash of spice.
Fruits were very mushy for the final harvests — perfect for a jam. Squeezing a bunch of the fruits in a mesh bag (such as used for women’s “delicates” in a washing machine) pushed out 
the pulp without seeds. No sweetener needed. Just jar it up and refrigerate (keeps about 2 weeks) or freeze. Delicious.
