Transplanted the arugula from the end of January into as small a corner of the greenhouse as seemed to make sense, two plants to a plug, about 6″ (15cm) apart. There’s no space to waste, and these guys, already a long time in trays, will likely be ready too early for market (first Saturday in May). So, another experiment in early planting, but leave room for others! The arugula has been out there in the plug sheet for a couple of nights, surviving 10°F (-12°C) nights under a few layers of row cover (an extreme rapid hardening off!; as you can see in the tray, a few much smaller seedlings, started in mid-Feb, didn’t do so well, most of ’em got toasted the first night). And now, the survivors are in the ground, free at last, in full sun during the day, and recovered at night. It felt great to put hands in the soil, first time this year. Mmmm…
Greenhouse
The basic tiny farming greenhouse is a steel-ribbed, plastic covered hoophouse, the bigger, the better for season extension.
Making water
As far as winter irrigation in the greenhouse goes, melting snow in big barrels is the next best thing to a really long hose, a well and an electric pump. Fill ’em up, cover with clear plastic, wait a day (even on a dull, cloudy day, it gets up to 60°F in the hoophouse). Repeat a couple of times, and you have 50 gallons of rainwater in a barrel! The alternative is dragging 200′ of hose through deep snow from the barn to the greenhouse, then reeling it in and draining it, every couple of days. The weather has put the kibosh on the early-March, barely heated greenhouse plan, the happy prospect until March actually came around. The nights have been regularly plunging to 10°F (-12°C), so it’s really not worthwhile to heat things up by 25°F. No worries. Adjusting expectations and schedules more or less by the day is all part of the fun… It’s never boring!
Back to the field!
Last seen planting garlic in November as we headed into winter, Lynn is BACK IN THE FIELD, getting a head start on spring. It was great to see her again and…continue! We headed out to the greenhouse and spent three hours or so, bagging the last of the grass mulch, pulling weeds, forking beds, chatting and basking in the sunshiny, 25°C (80°F) greenhouse weather! I also brought out a tray of arugula, couldn’t resist posing it in the snow… It felt excellent to get started out there. Fun!
Slightly snowbound
Another snowstorm, come and gone. It snowed steadily all of yesterday, with pretty high winds, but most of the accumulation seemed to be overnight. Today, azure skies, brilliant sun, tons of snow in drifts piled high. Looks like we’re one more heavy fall away from all-time records. I heard there’ve been over a dozen school snow days, compared to three or four a season in recent years. Here on the farm, no extreme hardship so far (knock on wood!). In the barnyard, we’re running out of room around the edges to pile up more snow, and in the field, it’s a couple of feet deep, but snow has kept off the Milkhouse roof, and the main worry, a flattened hoophouse, hasn’t come close to happening. The wind built up the drift on the south side (both photos), and just to be safe (and for the first time ever), I scooped off the new stuff, down to the harder-packed, more permanent base. Luckily, the side walls are inflated (a fan on a looong extension cord continually blows air between two layers of plastic), so the surface is quite taut and doesn’t sag or hold snow easily. And that’s it. Back to waiting for the snow to go…
My old friend the min-max thermometer
Clearing a path to the hoophouse today, I turned the corner and noticed the original min-max thermometer. I don’t usually. It was one of the first bits of gear acquired in Year 1, when the reality of FROST in the garden was a complete and scary unknown. The thermometer records the lowest and highest temperature that it’s hit; you reset it by pushing the little red button. It’s been hanging on the same nail in the same spot for three or four years, more or less out of sight and mind except in spring and fall, when I check it first thing in the morning to see how cold an overnight cold snap really got. Lately, the min-max is not such a big deal. Each different section of the field, and the particular crop in it, reacts differently to each cold night, so the only way to know what’s happened is to walk around and check things out. And I have confidence in row cover. I still check the thermometer, but it’s not like spring in the first couple of years, when I’d bolt awake at 6:00 a.m. and 10 minutes later be walking through the chill and dewy wet grass, adrenaline pumping, waiting for the verdict from the min-max to see what new transplants may’ve been toasted. It was kinda cool to be reminded, out of the blue, how that’s changed. In the case of gardening, at least, the more you know, the easier going you get!
Welcome to KeroWorld
What an odd thought, what image comes to mind: the world of kerosene… And now I’m in it! Purchased new today, at a healthy 35% discount, this small, rather inexpensive, KeroWorld-brand indoor kerosene heater is the core technology in the extended-spring greenhouse plan. The idea is to turn the unheated hoophouse into a barely heated one, by warming it at night so that it stays above 38°F (4°C). That way, I can put out seedlings weeks early, instead of crowding them under scarce indoor lighting until it warms up in April. It should also give the earlier-than-ever lettuce, going into the ground in the greenhouse, a smoother start. This heater is low-powered—10,000 BTU, recommended for 420 sq ft, it’s 640 sq ft out there—but only a wee bit of heat is required. I think. Last year’s propane space heater was quite efficient, but burned too much gas for every-night use, it often went out by itself, and it required lots of ventilation. Plus, I don’t really like relying on pressurized tanks. This heater will hopefully burn low and steady, and it’s pour-to-fill! Aided by a fan to keep the air moving, and row cover on the coldest nights, it should get the job done. This all reminds me of Patrick of Bifurcated Carrots’ comment a while ago about the line between good and bad technology. It seems a personal decision as much as anything. Why don’t I dream about full-blown winter greenhouses, with high-intensity lighting and industrial-strength heating and ventilation, I wonder? Dunno. I just don’t. But an extra growing month in the strengthening sun, and a little less reliance on indoor lights, traded off against some kerosene, well, THAT would be cool!
Still snow…
The snow hasn’t gone anywhere in the last week, and there’s not much to see or do out there. The greenhouse needs to be cleaned up and made ready for an early March opening. That’ll be a day’s work next week, I still have to purchase a heater (indoor kerosene, I think it’ll be). And that’s it for now for gardening outdoors…
