Hey, y'all! I'm new and happy to find gardenweb and the TN Gardening forum. Question - is Knoxville zone 7a or 7b, and does the distinction matter? I loved digging in the dirt yesterday (12-30) - warm, sunny, and just after a full day of rain. Looks like cold this week, though. I'll have to content myself with peat pots indoors! Any fun ideas for impatient gardeners in winter?
