Ah nice, I used to red peach tree that would flower too early. When the "fake spring" would start in February or March it would flower and then the frosts would return and kill the flowers. So many years we got no fruit at all.

I learned from this and bought a "late blooming" variety. So hopefully that will no longer be an issue. As yes the further north you go, the more of a chance the flowers will get wiped out.
