Post-winter greens

Post-winter greens

The covers are off and it’s all shades of green! That’s about three months, left to their own devices, living through freezing nights, often around -20°C (-4°F), and a low of -32°C (-25.6°F), under a couple of layers of medium-weight row cover, which means, little light (with the plastic added in, somewhere around 50% of already weak winter sun). Inside, at ground level outside the row cover, the lowest it got on the coldest night was an amazingly not-so-chilly-at-all -13°C (8.6°F). As a simple survival test…excellent!

 

Spring begins with the weather!

Two-week weather forecast

There’s official calendar Spring, and then there’s spring in the field, that ignores exact dates and goes by the weather, marking winter as over whenever the freezing temperatures end. If today’s two-week weather forecast is anything to go by—it is, in this case, when being off by ±5-10°C (14-23°F) either way isn’t a big concern—market garden spring starts now. For the moment, I’m mainly concerned about overnight lows in the unheated greenhouse, and whether row cover is necessary. If it stays above -15-20°C, my safe-with-no-cover cutoff, it should be fine to pull back the covers and let the sun shine in (prepared, of course, to put it right back if there’s a sudden severe dip, which we hope doesn’t happen). Nothing complicated, just a little of the gambling that’s called working with the seasons!

Today’s weather

Today's weather

Spring, soon! So far, though, still chilly and winterish. The photo describes it perfectly: not much snow, but cold enough for the thin layer to stick around (-10°C/14°F at night). And no signs of fresh new green growth just yet… It’s good to know, because it’s happened before, that it could suddenly turn into a startlingly warm T-shirt-optional March. Weather!

Sundown in the hoophouse

Sundown in the hoophouse

Not your typical postcard sunset, and it’s kinda chilly, damp and mucky in here, even as the temperature outside slides down to an overnight -15°C (5°F). But it’s all about the greens, tucked under a couple of layers of row cover, maybe not exactly cozy with only ground heat to keep them warm—who knows how they’re really feeling—still, well-set to survive another sub-zero night. With that in mind, sundown through 6 mil plastic is a cheery-enough sight to see!

Great gloves get a little better!

Good fieldwork gloves for fall and winter

How excited can you get about a pair of gloves that you use to work in the field? Quite! Although enthusiastic may be the better word. This style of glove I’ve used for a while, for fall and winter, in cold weather. I wrote about their many fine features a while back—this particular version is the best yet, with the grippy, waterproof coating extending just far enough down the back so that they don’t get wet during normal handling of soggy stuff, while allowing enough open, breathable area so your hands don’t sweat. What more can I say?!

Cold crop lettuce

Greens in unheated hoophouse after the deep freeze

Lettuce in the unheated greenhouse, under a couple of layers of medium-weight row cover, is doing fine so far, firm and tasty after weeks of sub-freezing nights, all the way down to -30°C (-22°F). Now there’s even a noticeable bit of grow-back from the last cut, late December (even the weeds are getting in on the protection, see bottom left). My first full-winter tiny farming experiment continues…!

Wire work

Fence wire as row cover support

Electric fence wire work, snipping 6-foot pieces of 9-gauge wire for hoops to hold up floating row cover in the greenhouse. Hopefully this wire is stiff enough to do the job, supporting up to three layers of row cover, heavy with moisture from humidity and being dripped on by water condensed on the inside of the hoophouse plastic, or weighed down by ice, when the soaked cover freezes at night. This test batch of about 180′ came coiled, in a circle about 2½’ in diameter, and the built in curve is perfect for stretching slightly to span about 4′ of bed. So, no bending required, it’s all about the snipping!
