Fruit trees are not pruned now because you only will cause a proliferation of water sprouts and unwanted growth. It only becomes a broomstick looking thing that does not fruit. The only pruning that should be done on a fruit tree now is to eliminate weak and crossing branches. If you planted an apple, apricot, peach, cherry or plum last year, buy a book on pruning.
Summer pruning after the shine is off the leaves is the best time to prune fruit trees.
Look at the tree now and use a dab of white paint to mark branches that must go when summer comes. Water the trees, shrubs and perennials. Even though we've had some snows, the south sides of building are receiving hot sun now. I have an electronic moisture meter, and I found the soil at 20 percent last week on the south side. The soil on the north and east are still frozen, but not for long.
