Growing zones in VA
How do you get specific info about which zone you are in? I am in zone 6, but everyone hesitates to say that as if they are not sure. From the maps I see (which I can't really see clearly) I am in either zone 6, 6a or 6b. I am just curious, but it is annoying that I can't get the exact answer. I am in Augusta Co. near the Blue Ridge and Appalachian Trail.
If you know of a good map or chart that is not too tiny to see counties can you recommend it to me?
