With last night’s forecast calling for -3°C, I finally figured a little floating row cover frost protection might be a good idea. In fact, though, with the cloudy, windy, wet conditions right through to Saturday evening, a solid freeze didn’t seem all that likely. And that turned out to be the case. The min/max thermometer outside the greenhouse registered a low of -5°C, but only a few crops suffered minor damage. Even the basil, which is really tender, did well: the top layer of leaves took one for the team, but the rest were fine. Here, some sweet pepper plants sit under cover, but the forecast for the next week is…quite warm. When exactly does the season end?

After a chilly and only reasonably busy day at the farmers’ market, it was a bit of afternoon nap time, and then on to making the first frost decision—to cover or not to cover—of the fall season. I “consult” four different online weather services, in general trust none to be very accurate, but when it comes to more dire predictions, like super high and low temperatures and mighty gusting winds, a certain one out the four usually stands apart and is…quite accurate. True to the norm, today three services forecast overnight lows of around 5-7°C (40-44°F), while the dire one calls for plus 1°C with “risk of frost”. So, a couple of hours before sunset, we started assembling floating row cover kits near tender crop sections. The cover, 14′ wide and cut to 50′, is kept loosely rolled on 4′ lengths of 2×2. Heavy rocks, 10lbs and up, are gathered and kept track of over the season. And that’s all you need: row cover and rocks! Unlike for insect protection, where edges of the cover should be buried, or at least, anchored firmly every few feet, frost protection only needs draping over top, and tacking down at the corners and a couple of additional spots. Anyhow, in the end, I considered the breeze, the slight cloud cover, and my…um, instinct (?!), and decided not to cover…

The early lettuce has company. Several other varieties of lettuce, self-seeded from last year’s crop that was left to flower, just took off. Somehow, there’s tasty arugula mixed in as well. To munch on and to fill in where the voles had their fun, I let it all grow. This year’s lettuce is in there, doing fine, and should be ready not for the first day of the farmers’ market, which is this Saturday, but probably for next week. It’s all…good!

The cold spell seems to be broken, the nights are going down to zero F instead of -10. Time to start moving the main act to the hoophouse. First out, some hardy brassicas: a tray each of broccoli and bok choi, and a mixed tray including some parsley that I set out a couple of days ago as an extreme cold test. This is my first year for early season brassicas, so I’m a little cautious, although I’m well familiar with their general hardiness in the fall. These probably could’ve been out earlier. In front of the table, the lettuce, with the carnage renewed. Overnight, the voles tore apart another 10 seedlings, and I noticed they’d eaten the growing points off another dozen of the red lettuce, taking the toll to 30-40, depending on whether a few recover. Measures, as in, more strategically positioned snap traps and filling in the perimeter, have been taken. In any case, no worries, there’s lots more on the grow! OK, sitting beside the trays on the table, there’s the Heater, intended for construction sites and the like, which hooks up to a regular BBQ propane tank and provides a good amount of heat for surprisingly little gas. It’s not needed yet, but when the tomatoes and other tender guys come out, it will likely be on at night.
