I am in zone 8a. 2010 set records for the highest and the lowest temps. Last winter we had a miracle. Most snow ever, ever. We usually get a dusting ever 5 years or so. We had snow multiple times and 14 inches once that broke everything. This past summer we had over 30 days of 100+ and the rest were 98-99. Lost more to the heat than we did to the cold. It wasn't the temps so much as the suns rays were so intense, they scorched the leaves of just about everything. When it is too hot for okra, it is too hot!
I don't have all that much room. May leave some in the pots and put others on the shelf.
