I guess it's all relative. We lost almost all our apples last year and the year before because of late frosts, and my kids planted the vegetable garden several times. Maybe this year we'll do better. We have some really old apple trees. They're small and gnarly looking but much tastier than the new ones.
We usually plant everything 1st June, long summer sunshine warms everything up last week of may. 50-50 that you'll have a frost until 3rd week of june, but then usually good until 3rd week of august. LOw places and along river sometimes gets hit more often. I'm even thinking about sweet potatoes under plastic this year and I have friends that actually grow their own 4-5 foot tobacco plants and say its better than no ciggs at all.
I know people that grow spliced apple trees and they survive the minus 60 winter temps but the moose are hard on them.
