Moved the first wave of tender seedlings—100 tomatoes, plus eggplant and sweet peppers—to the greenhouse yesterday, with zero (32°F) predicted for the overnight. There’s just no more waiting, with all of the light space in the Milkhouse…taken. It’s a long way from the ambitious barely-heated greenhouse plan of February, but there’s row cover, and the new KeroWorld heater is ready for action (it’s the white box in the middle)… That’s how some plans go when you’re dealing with the WEATHER. Elsewhere in the hoophouse, I’ve let the early lettuce and mesclun blend with volunteer lettuce and arugula from last year’s early stuff going to seed. It’s unruly, tasty, and growing fast. I don’t know how much of it will make it to the farmers’ market: since there’s too much to do around here, I’m not aiming to go extra early this year (yesterday was the first market day), but one way or another, the greenhouse greens will get eaten!

With the warmer weather of the last few days, things are moving along a little quicker in the greenhouse. The patch of arugula transplanted so long ago is finally starting to fill in new, full-size, TASTY leaves. And the all-lettuce mesclun, direct seeded two weeks ago, has been appearing. Even though days in the greenhouse have been way warm for weeks, the frigid nights really slowed down growth. Warmer nights mean faster greenhouse action!

Last night, the greenhouse low was a chilly 5°F (-15°C): the arugula, spending nights under 3-4 layers of floating row cover, still seems to be doing fine. Especially with more extreme transplants like this—a long time in the plug sheet, then an abrupt jump to the harsh greenhouse conditions—there’s a critical period of a few days, waiting for the stressed little plants to settle in. Cover at night, uncover in the morning, till the weather warms up…

Can’t speak for everyone, for me, heading into the field is the best walk to work I’ve known… The arugula transplants a couple of days ago started this season’s almost ritual morning garden tour. This is an often mildly adrenaline-fueled stroll at the start of every day, from mid-March through early June, and then, mid-September into November, to see what happened with the overnight temperature. Frost-watch, if you like, but actual visible frost you don’t see that often, it’s mostly checking the effect of really cold air on crops in different parts of the garden. Right now, there’s only the bit of arugula to check out (the unheated greenhouse gets as cold as outside once the sun is gone). We’ve kept a path clear to the east side door, where there’s less snow build-up, as the wind usually comes from the west (the greenhouse is laid out east-west, with doors at both ends). Today, all’s well!

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…

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!

The arugula, about a month from seeding, is looking lush and…TASTY. While fiddling with macro focus and tripod (I’ve been using a borrowed one lately for indoor pics), I reached around to pluck a leaf. And another… I’ve been wandering back all morning for quick tastes. You either like arugula, or you don’t (can you be MADE to?)… It’s an easy, not subtle, veggie rush: first the familiar arugula flavor with that hint of mustard, slowly building as you begin to chew, and suddenly—wait for it—BAM, a little peppery explosion. I’m fairly new to this treat, it’s only since tiny farming that I paid attention, though I knew the taste, and only last season that I grew it out of salad mix, as a separate crop. It’s still a bit of a novelty. Here, the two varieties, somewhat generically named Rocket (smoother-edged), and Skyrocket, have quite different leaf shapes, but so far, I don’t think I could tell the tastes apart. These are two to a cell, and heading out to the greenhouse in the next week or so… (I should note, arugula grows fast, you can usually start harvesting 30-35 days from seeding, so planting this early indoors wasn’t exactly necessary, just a pre-season experiment.)

Time to thin out the lettuce and arugula. Between the seven varieties, some of the seed I used was up to four years old, so to be safe, I was quite generous, maybe 4-5 seeds per cell for the arugula, and a bit more for the lettuce (that tiny seed can get away from you, though with new seed, I try to go lighter). Germination was good, and the little seedlings are already shading out each other as they push for the light. I’m still getting used to timely, to-the-point thinning, both in the trays and in the field. I usually have the urge to leave ‘em a while longer, but almost always, this ends up being not the best thing to’ve done. Give the best ones the biggest break as early on as possible, which means, kill off the rest. This also takes some timing experience, but in general, it’s hard to go wrong by not waiting around. Sounds brutal, but that’s about it! The lettuce will eventually be one per cell, although for now I’ll leave a couple per. Starting arugula indoors is a first for me, I usually direct-seed, so I’m figuring things out this time around. I’ll leave two per cell, and plant them out two together at 6″ (15cm) spacing and see how that works out. Here, I’m snipping arugula at the soil level with wickedly pointy little shears…

That was quick! Early morning, and the arugula (and Granada lettuce) has popped up in barely two days. Air temperature in the Milkhouse where the grow racks are stays mostly in the 60-65°F (15-17°C) range. Around the plugsheets, the close fluorescents warm things up an extra 5°F or so, and the clear plastic over the trays creates a little greenhouse effect that adds at least a couple more degrees. Altogether, ideal germination temperature! It’s kinda fun to think you’re in control of precisely what’s going on, but in any case, however they pulled it off, the first seedlings of the year are good to see! :)
