Hardening off help

jhook1997(7)March 27, 2013

Here in zone 7 our weather is very unpredictable during the time when I need to be hardening off my "cold crops". I have cauliflower, Brussel sprouts and cabbage that I started several weeks ago. All are getting to the point of having several leaves but are still pretty wimpy. I started taking them out last week to harden off but only got to do it two days. It is now WINDY and too cold for that! I have a cold frame built and sort of a glass tunnel made from windows that I use when hardening and what I'm wondering is.....at what point/temp. can I just leave them outside in those? I can obviously protect them from the wind but what temp. can the cabbage and cauli withstand?

Sorry, new to the Forum....probably should have put this in "seed starting"

ah.. whatever.. on where you posted ....

though the plant itself might take the cold.. in the pots.. i would worry about the pot freezing.. or the roots getting too cold ...

*** what i was trying to say.. rather inarticulately.. is that you can not presume a mature plants hardiness.. on a tiny seedling ... and that is what the 'hardening off' process is all about.. on some level ...

I set seedlings outside for the sake of sun, wind and rain during the daytime and into the evening.
If I'm concerned about the overnite conditions I bring them in before bedtime, or otherwise shelter them.
Cole crops in our area can get very close to freezing before I get concerned. It is a good caution about pots as stated, especially as the temps go down toward freezing. :)

I see you are in zone 7 same as me. My cold crops have been out about 3 weeks now. About ready for tomatoes to go out. They have been outside about a week now but had to roll them into garage a few times at night.
