I would plant my colards immediately. They like the cool weather . Normally we plant our greens in Sept. but Calif. has nice weather. As for the Okra, it is diffinitely a hot weather crop & needs to be planted in May or june.
Uh, generally the cole crops like cabbages can take it down to around 35 and above. I've had my collards out as low as 32 overnight and they love it around 38-45. Mustards are more tender than collards so my cutoff for them is around 45-40 degrees.
The operative is "how LONG" the cole crops remain out in those sustained temperatures:
►A couple hours below 30 degrees overnight, no problem.
►More than a couple hours below 30 degrees, throw a sheet over them
►Sustained temps below 30 degrees for more than a couple back to back days, no problem with some protective covering (water the leaves down before covering, and make sure the cover doesn't touch the leaves or they'll burn when they touch).
►More than a couple days below freezing for an extended period of time (say more than 4 solid days with no break in the freeze from the warming sun), and I'D freeze too...
This winter has been as low as 10 degrees with consistent temps in the low 20's. Collards are still trucking along altho most of them have been harvested. They do freeze and look very droopy, but when it warms up a bit, they perk up and go again. As long as the ground does not freeze to any depth, they will be fine. Broccoli survived but is not robust. Surprising was the Japanese mustard spinach, it showed few ill effects.
That explains a lot *g*. I have a little patch of broccoli, kohlrabi and a few romaine type lettuce(s), which I'd thought would be ready long ago. The early/severe (for us) cold Farmerdill mentions seemed to put a halt to their growth, but because there was no need to pull them out, I built them a low hoop house type thing, and covered them (sometimes for days) during the worst of it. I was afraid to open them :). When I did, expecting mush, they were in surprisingly good shape, even after 11 degrees. It did get above freezing most days, but they got no sun.
Now they're in the "open". and seem to be fine, even growing a bit. The lettuce had some withered leaves, and one broccoli is done for. Interesting :)
I have little chard plants finally starting to grow, they are maybe 2 inches high, cute little buggers, its been so sunny out I am hoping they can handle the heat. I hope everyone everywhere else gets a nice thaw soon!
My greens including chard, kale, collards, oriental greens and turnips are all of a sudden growing a couple of inches a week. Everything was planted in late October or early November. Our turning point was finally getting some blessed rain. It is still in the 30s many nights here and we have had a lot of freezes but nothing has died but some lettuce.
I am most impressed by the baby bok choy. They are delicious, pretty and seemingly indestructible. My new favorite.
Oh, good! I bought some seeds to plant, and I've been waffling. You have convinced me:).
We've been very cold (for SC), but my November brocolli finally has some tiny heads peeking out from their leaves.
Of course, it's supposed to snow tonight, so I have to decide to cover, or not to cover. They SAY very light, but the weather accuracy has been less than stellar this year :(
Are you in the Atlanta, Ga. growing zone? I have a cousin who's joining Dave's and trying to get a good planting schedule down for her spring? garden. She says she plants tomatoes in May (when I'll be harvesting). She has successfully grown humongous watermelons and cantaloupes, so she's not a total newbie.
However, she's interested in container gardening. She does have a large property available for some planting, too.
Any tips on when she should start her seedlings would be much appreciated.
I am about 150 miles south and east of the Atlanta metro area. I start tomatoes, eggplants ,peppers around March 1 for tramsplant around the middle of April. Last frost date April 15. Spring brassicas started in cold frame around the first of February for transplant in mid March. Maybe a few days later in the suburbs north of Atlanta, but not wildly different.
