I'm curious to know whether planting a fruit tree that requires longer cold hours would be best planted in a location that gets full sun in summer, yet full shade in winter (aside from an hour or two in the afternoon). My consideration is a cherry, but I want to be sure what I'm planning to do won't kill the trees in winter without much sun.
Since the tree is mostly dormant and leafless in the winter, being in the shade shouldn't matter at all. In fact, you may delay blooming, which is usually a good thing with early-blooming stone fruits in most of the East and South, where a late surprise frost often damages the bloom.
Can I assume that the tree will be in the shade because a building is blocking the sun. If that is the case, I'd suggest the opposite would happen. That is the proximity to the building (your house?) will tend to protect the trees and moderate the winter cold.
As an alternative I'd suggest looking specificly for the few cherries that are known to be low chill. The varietes "Minnie Royal" and "Royal Lee" only need 200-300 chill hours, vs 700-800 for something like Bing. If those aren't available to you, then maybe "Lapins" or "Stella" which need somewhat more chill, about 400 hours.
