From the dirt doctor library:
All fruit trees should be pruned late in the winter just before bud break. Pruning earlier can cause early blooming and late freeze damage.
Leave them alone this year, except you should double check to be sure that they aren't planted too deep. The root stock (the graft) needs to be completely exposed and the flare needs to be in view, the bole shouldn't be poking straight out of the ground like a post. The flare is the spreading part at the base of the tree. I mention this because it is a mistake frequently made when planting grafted fruit trees.
