Patchy frost

Eggplant under row cover

[Fri, Sep 16, 2011] First frost wasn’t too bad at all, a patchy frost that hit the field lightly, and in some areas, hardly at all. Still, the row cover, over some beans, peppers, eggplant, and a couple of beds of cherry tomato, worked out well, the exposed plants in those areas did get mildly to quite well…toasted. In the pic, we have Dusky eggplant, under its thin layer of salvation. Raising the floating row cover with a few non-pointy sticks, so it’s not pressing on the leaves, is a good idea—moisture often collects where the leaves touch the cover, freezes, and can deliver some pretty severe leaf burn. But for mature plants at this point in the season, I usually don’t worry about that—it’s different with seedlngs at the other end—and just float on the cover and leave it at that!

Frost protection time again

Row cover frost protection

The frost-warning forecast from a couple of days ago, for 1°C (34°C), moved up a day to tonight. so there’s row cover all over the field. Some of it was floated out against the possibility of frost, the rest, as so-far-effective deer deterrent. Up front, around 800′ of snap beans, just starting to form, are bundled up against the cold. Then, row cover over carrots, and farther, lettuce, has been in place for a few days, and seems to still be keeping the deer from munching. In the distance, peppers and eggplant are under frost protection. Elsewhere, we’ve covered a few beds of cherry tomatoes to prepare for tonight. Winter squash and pumpkins are mostly in, and summer squash and cucumbers are finished, and the rest out there are hardy enough, and that’s about it!

Frost? Take your pick!

First frost forecast

First frost on Friday? It all depends on whose forecast you believe in. Because, as I’ve discovered over time, all weather forecasts are not created equal. The online weather page we’ve used for the last few years is often in sync with the others, but when it comes to cold, it can go its own way, and it’s usually right. Here, we have a low of 1°C for Friday, OR, I can go for a more veggie-friendly choice of two 6°C’s and a 5°C, from three of the big weather outlets. That’s the difference for me between row covering all the tender crops we’d like to save, and…not. There is a pattern: sites like this one that’re based on Environment Canada’s weather service (that’s the Canadian government) tend to be several degrees lower and more accurate. So it’s on with the row cover on Friday, then wait and see!

Fall frost watch 2008

Floating row cover on sweet potatoes

Tonight is the first real frost watch of the year. I covered a bunch of beds for a couple of nights last week, but the chance of frost seemed slim, with the overnight forecast around 35°F (<2°C). Today, they say it’s supposed to go down to 33°F (0.5°C), with clear skies and no wind, perfect frost conditions. Under cover: peppers, eggplant, summer squash, beans, cucumber (a really late experimental planting), basil, sweet potato (above). It’s floating row cover is the usual Agribon AG-19, in 14′ ((4.3m) widths. Let’s see how it goes…!

After the row cover: weeding!

Weeding after row cover

It’s been about six weeks, time to permanently remove the row cover from the last transplanting of fall brassicas! There are two sections, about 20 x 50′ beds in all, with broccoli, caulflower, cabbage, collards, kale. The cover protected against flea beetles, and at this point in the season, the FBs aren’t around much. Which leaves the post-cover weeding! I generally plan to remove the cover earlier, weed, and then replace it quickly, but this seldom seems to happen. Instead, it’s one big weed-a-thon at the end… Here, the mainly pigweed looks fairly big and dense, but it’s actually not much of a problem. The row cover has protected the ground from many days soil-packing rain, so the beds are nice and loose (it’s amazing how much rain can compact clayey soil).  Weeds come out easy! With two people, it’s a relatively quick job, 2-3 hours for a pretty thorough clean-up. We worked with a combination of hoe and wheel hoe, me doing the paths and between-row clearing, and Lynn hand hoeing in-row, between the plants spaced at 18″ (45cm)…

Wheel hoe in brassicas

Each time I use the wheel hoe, I grow to love it that much more. So easy, so TIME-SAVING! It’s such a sophisticated yet simple tool, a perfect marriage of wheel, leverage and steel (you could say! :)… Today’s job is heavier work than it’s usually used for, the weeds aren’t just emerging, they’re pretty big. Rather than rolling the wheel hoe continuously down the rows, I’m cutting the weeds with a series of forward and backward strokes that either slice the plants below the surface, or pull them out, roots and all…

Wheel hoe: before and after

Clearing a path (before and after, above) in the loose soil takes maybe 3 minutes for 50′, many times faster than hoeing or hand pulling…

Wheel hoe forward stroke

For this heavier weeding work, I use a fairly forceful forward stroke that travels about 1-1.5′ (30-45cm), then raise the blade to clear the felled weeds as I step forward to start the next bit…

Wheel hoe backstroke

The wheel hoe is equally good at cutting on a backstroke, which comes in handy for dense areas and tough specimens… It’s not particularly strenuous work: the blade is sharp, the wheel and angle of the handles give lots of leverage and momentum, and some part of the hoe is always in contact with the ground, so you’re never completely lifting the whole tool. Like most things I do here in the field, I’ve figured out how to use the wheel hoe on my own, by reading instructions, looking at pictures and applying my version of common sense. Techniques no doubt vary. It’ll be interesting to eventually see how others do things! Meanwhile, everything seems to work out…especially, the wheel hoe! (Wheel hoe action photos by Lynn)

Fall crops

Fall carrots and brassicas

Not much to look at, yet, but the last plantings of 50-day-plus fall crops are doing fine. Here, carrots and, protected from flea beetles by floating row cover, one of two sections of brassicas, including broccoli, cauliflower and kale. There’s a bit of timing risk here, depending on the weather, if growing goes slow, they might not make it to maturity in time for market. But the sun’s been shining for a couple of days now, and the long range forecast is for more of the same. If all goes well, these will be ready for harvest through October!

Weeding summer spinach

And the summer-seeded spinach couldn’t be doing better. There are two plantings, the first on July 22, and the second (left of the photo) a couple of weeks later. Here, Lynn hoes the first set: in this summer’s wet, cooler, cloudier conditions, germination was absolutely solid, as good as or better than regular spring seedings. Fall spinach has never been this good, by far. Excellent!
