This is really interesting..thank you!
we got moved to 6a as well from zone 5 that I always used.
SPS you welcome.Jenny I'm surprised they moved your area up. Some things I think I will be able to start earlier, but there is other vegetables I'm not so sure about. Trial and error as well as time will tell.
are you planning any new varieties of tomatoes this year? i know you have alot of space to play with. if you want i can send you some interesting types that I'll be trying this year.
