I know the feeling. Our temps are in the 70's and 80's at the moment. Sun is shining. Trees are swelling buds. Birds are singin.
Trouble is...for our area...we typically get frosts into mid/late April. I have planted a couple tomatoes outside anyway, knowing I will probably lose them (but maybe not). Potted fig trees and cuttings and vegie starts are all outside at the moment. Watchin the weather forcasts like a hawk, ready to bring everything in if/when need be.
Spring will be here soon enough. Now would be good, I know, but it will happen when it happens...
