Winter’s Comin’
Ready of Ol’ Man Winter
October 31st, was slated to be the first hard frost of the season, later than ever. That afternoon, I went down my checklist of things to do in preparation for the cold.
Drip irrigation needed to be shut down so that ice wouldn’t damage the lines. I opened up the drains at the ends and at the low points of the main lines. I also opened up the valves on all the drip lines so water wouldn’t get trapped anywhere. Some people blow out all the lines with compressed air.
The only parts of the drip system that ever need to be brought indoors are the parts near the spigot: the battery-powered timer, the pressure reducer, and the filter.
But I wasn’t yet finished with water. All hoses got drained, with any sprayers or hose wands removed from their ends. Hoses were also removed from frost-free hydrants to let the water drain freely out their valves. (The hydrants are frost free because water drains and enters the hydrant’s pipe four feet below ground, where temperatures, even in winter, remain at a balmy 50° F. or so.)
Tropical plants indoors
Moving on to plants . . . Tropical houseplants had all been brought inside, but outside still remained subtropicals, including some potted figs, pomegranates, bay laurel, olive, and an angel’s trumpet (Brugsmansia). Subtropical plants can tolerate, even enjoy, temperatures below freezing, even down as low as 10°F. for some of them. My pomegranates, the varieties Kazake and Salavatski, both from western Asia, are reputedly cold-hardy to below 0°F! All these subropicals will enjoy the great outdoors for a few more weeks, barring a drastic change in the weather.
Some vegetables remaining out in the garden can likewise weather cold weather well. Just to make sure, though, I laid “floating row covers” over beds of endive, mustard greens, and lettuce. These diaphanous coverings keep plants beneath them a few degrees warmer while letting light and water filter through. The soil retains enough heat to protect roots of turnip and winter radishes, which are further protected beneath their leafy canopies.
I forgot to pick and eat Sungold tomatoes, which would be done for after a freezing night. Any red peppers still left on the plants had been harvested; those plants would also be dead on the morrow. I can’t complain; the Sungolds and the peppers bore well and for a longer time than ever before.
The final cold prep was to check the greenhouse, making sure window, sidewalls, and doors are closed up tight, and the heater is functional.
I’m ready for Ol’ Man Winter.
Not So Cold
The morning after: The cold turned out to be not nearly as dramatic as expected. A little before sunrise a cloud cover crept over the sky, tucking in the earth’s warmth rather than letting it radiate out to a clear sky. The low temperature for the night was 28°F. Even the pepper and tomato plants had toughened up enough by then to tolerate that amount of cold. Not to keep ripening good-tasting fruit, though.
Temperatures aren’t predicted to drop near freezing for many days after that night, but I didn’t consider my scurrying around to move or cover plants, and drain water lines, to be wasted effort. Endives and other greens still out in the vegetable garden transpire very little water in cool weather, and even less so when covered with floating row covers.
The only watering needed from then on would be of the compost pile, easily accessible from one of the frost-free hydrants and a short length of hose, connected as needed.
“Trip” to the Mediterranean
Greenhouse temperatures dropped only to 40°F, the temperature at which I set the thermostat. Cloudy days in there are like today are akin to winter days along the Mediterranean: Very cool and somewhat dreary. On sunny days, I open the greenhouse door to bathe in a tropical paradise of sunlight, heat, and high humidity, with lush plants of lettuce, mustard, arugula, celery, chard, claytonia, and parsley blanketing the ground. 
Fig trees in the greenhouse have slowly eased their way into dormancy. I hurried them along by lopping them back — except for the few branches still ripening a few fruits. Those figs, ripening in low sun and cooler weather (even in the greenhouse), aren’t as tasty as those of summer and early autumn. I wonder how tasty November figs are in Italy and Greece?
The Morning After
Endive Galore
I don’t know if was a case of green thumbness or the weather, but my bed of endive is now almost as frightening as a zucchini planting in summer. The bed, 3 feet wide by 20 feet long, is solid green with endive plants, each and every plant looking as if it’s been pumped up on steroids.
I sowed seeds in 4 by 6 inch seed trays around August 1st, “pricked out” the seedlings into individual growing cells filled with homemade potting soil about a week later, and transplanted them into the garden in the beginning of September. The bed had been home to one of this summer’s planting of sweet corn (Golden Bantam), a heavy feeder, so after clearing the corn I slathered the bed with an inch depth of pure compost.
Perhaps the vigor of these plants also reflects the extra space I gave them. In years past I would cram 3 rows into a 3-foot-wide bed. Because we never can eat all the endive I plant, this year I planted only 2 rows down the bed. Hating to see any wasted space in the garden, I set a row of lettuce transplants, now eaten, up the middle of the bed. The endive plants have opportunistically expanded to fill whatever space they can.
Fortunately, there’s no rush to eat all that greenery. The bigger they get, the more the endives’ leaves fold in on themselves to create blanched, succulent leaves of a loose head. Upcoming cooler weather also brings out the best flavor in these plants. After being covered with clear plastic, which I’ll support with a series of metal hoops, the endive should remain flavorful for weeks to come. That’s assuming the muscular plants can be fit beneath the hoops and plastic.
I do have a Plan B: Just as zucchini bread was invented as a way to deal with zucchini excess, white bean and escarole soup might be just the ticket for my escarole “problem.”
Floating Row Cover
Another bed, planted from seed sown on August 15th, is also full of greenery. Not nearly as dense, though, which is okay because the bed is planted for its roots. Up the bed run 2 rows of turnips and one row of winter radishes.
One year I couldn’t see the turnip and radish bed because I had hidden it beneath a “floating row cover.” Floating row covers, which let water, light, and air pass through, are so lightweight that they can be just laid on top of the ground to be pushed up by growing plants. That year, I made it even easier on my plants by propping the covers up with the same kinds of metal hoops that will hold the clear plastic over the endive bed once the weather turns cold. The row of hoops propping up the plastic creates a tunnel that, every year, looks like a sleeping, giant, white caterpillar. 
The purpose of the floating row cover was to block the root maggots that typically tunnel into many — too many — of my turnip and radish roots. Beneficial nematodes are supposed to help deal with that problem, but have been — in my experience, at least — ineffectual.
This year, for no apparent reason, most of the turnips and radishes are free of maggot attack.
A View From Above
Every morning I look down from my second story bedroom window at the garden. Closest in view is the bed of endive; looking further back, my eyes come to the back of the garden, where a row of tall, thin evergreens stand sentry to block the view of the compost piles. Those evergreens, spires of the Emerald (also known as Smaragd and Emerald Green) variety of arborvitae, are among the commonest of landscape plants. I like them.
The trees are at their upper limit of 15 feet high and 5 feet wide, and create a perfect screen without needing too much elbow room. They’re also perfect for injecting a bit of civility to the more frowsy gooseberry bushes and overgrown (at least till I prune them) grapevines in the foreground. Some arborvitaes turn a muddy green in winter but Emerald keeps its vibrant green color.
To the north, just beyond the garden is another row of spires, five plants of a juniper variety called Gold Cone. Each plant will mature to 10 feet tall with a spread of a mere 3 feet, just enough to hide my Cool Bot walk-in cooler, now home to boxes of apples, pears, pawpaws, cabbages, carrots, and persimmons. Livening things up is the gold coloration at the tips of Gold Cone branches.
Timing Gone Awry But Composting On Schedule
Time Change
Much of gardening is about timing — getting tomato plants in the ground early enough for a timely harvest, but not so early that transplants are killed by a late frost; checking that there’s enough time following harvest of early corn for a late planting of turnips, etc. So, when I began gardening, I read a lot and took lots of notes on what worked here in Zone 5, and eventually compiled everything into a neat table of when to do what.
I figured, with that table, that I was all set and would no longer have to respond to a gut impulse to plant peas during a freak warm spell in late February. Or to keep reading seed packets and counting back days to maturity to compute if there was still time, or it was too early, to plant a late season crop of endive.
Not so! In the few years I have gardened, which, though decades, is infinitesimal in geologic time, the climate has changed enough for me to have to shift those dates I so carefully figured out. No longer must I wait until the end of May to sow okra, squash, and other vegetables; the ground warms sufficiently to induce them to sprout a couple of weeks earlier now. No longer does a hard freeze strike tomato vines dead by the end of September. As I write, it’s the end of October and last night the first frost — a light frost — crept into the garden; later today, though, I’ll be picking ripe Sungold tomatoes.
Some perennial plants that, in the past, usually died back to the ground each winter, then resprouted in spring, no longer die back. Yellow groove bamboo, for instance. Nowadays their leaves stay green through most winters, which translates to taller and thicker canes. Crocosmia corms would hardly flower in years past; nowadays I don’t bother to dig up the corms, which flower and spread prolifically.
Taking Care of My Little Pets
Some things, gardenwise, are timeless or, at least, not time sensitive. The changing daylength throughout the year, for instance. And composting.
Although I feed my compost “pets,” that is, all the micro- and macroorganisms living and working the compost pile, all season long, this time of years those pets have a veritable banquet. In addition to the usual trimmings and scraps from the kitchen, beds are being cleared of corn, beans, okra, cucumbers, and all those other summer vegetables that are petering out.
I’m also having a lot of fun weeding. Yes, fun. Yes, weeding. (You might wonder why the author of the book Weedless Gardening has weeds. I grow a lot of fruit trees, shrubs, and vines, and some flowers, in addition to vegetables. I have too much garden. I can’t help myself. But everything is Weed-less.)
The ground has enough moisture in it so weeds are easily pulled. On my knees, I pull at a clump of Creeping Charlie, and creeping vines extending for 2 feet in all directions move up and out of the ground. I grab a clump of quackgrass and, if I lift carefully, a couple of feet of its creeping rhizome that attempts to extend its reach releases from the ground.
All this goes into the compost pile along with some horse manure and bedding, some hay I scythe from my field, and occasional sprinklings of soil and dolomitic limestone. As I layer these materials, I pay attention to their ratios of carbon and nitrogen, the two main feedstuffs of my compost pets. Old plants are relatively richer in carbon, young ones in nitrogen. Manure is rich in nitrogen, the bedding (wood shavings, which is old plants) in carbon. Too much carbon, and decomposition is sluggish. Too much nitrogen, and the pile gets smelly.
I also consider how fast ingredients might decompose. Wood shavings, for instance, are high in lignin, which slows decomposition no matter what their ratio of carbon to nitrogen.
The Little Guys Are (Usually) Thirsty
Two things that often slow composting are heat loss and insufficient moisture. Small compost piles lose too much heat; the critical mass for good heat retention is about a cubic yard. The bins into which I pile ingredients insulate the edges to further retain heat.
A lot of water is needed to seep way down into a pile. Rather than keep trying my patience holding a hose wand, a couple of years ago I purchased a small sprinkler and attached it to some plastic pipe so it fit neatly on top of my compost pile. A pressure regulator (usually used for drip irrigation systems) keeps incoming pressure constant so I could adjust an inline valve to make the spray consistently reach just to the edge of the pile. Twenty to thirty minutes gives my compost pets a good drink.
A long-stemmed compost thermometer is my final check that all is well. The piles typically reach 150°F. Compost piles don’t need to get that hot; more time composting also does the trick. Any pile of organic materials eventually becomes compost..
