Uh, yea. It definitely gets below zero here. Lowest this winter was something like -20 with windchill to -50.Well, we've got nearly a foot of snow in the forecast for the weekend. Yay...
And I concur. Even a greenhouse can't save peppers when the temps drop below 0, and it happens here, and in your zone as well I believe BReeder! ? And one round of fungus gnats is enough to last a lifetime for anyone.
I think we are done with snow though. Temps are warming up. Hoping we don't get any more snow and last frost date might be early this year. Still playing it safe for now though. Last frost is around May 1st normally. I think In going to risk getting potatoes in on April though. I might even risk peppers and tomatoes outdoors in late April if the forecast looks right.
