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.Compost bins

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.Compost sprinkler

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..
