|When and how do we prune our new peach tree?|
|Since peach wood is very sensitive to cold damage, you should do your pruning in the spring, as close to bloom time as possible. Peach trees produce best when trained to an open center, meaning that you want to end up with 3-4 main side branches ("scaffold branches"), avoiding a central leader trunk.
If your tree has had no previous pruning, head it back to 30-36" tall. Scaffold branches should be at least 20" off the ground and form a 45 degree angle with the trunk. If the tree has good candidates for scaffold branches, cut them back to 4-5". They should have at least a couple of buds each, which will branch out into fruiting limbs. You should have all the scaffold branches chosen and pruned appropriately by the beginning of the spring after planting. At that time, remove all other branches and any root suckers (sprouts emerging from the roots).
If during the second summer you notice the scaffolds bending to a wider than 45 degree angle, you'll need to remove some wood, lessening the weight on the branch. It's the only summer pruning you should have to do. By the fourth year, the tree should be bearing, and your pruning should be reduced to removing dead/weak/crossing/damaged branches, with the goal of keeping the center open, and the lateral branches within easy picking height. Older, slower growing trees need even less pruning--head back lateral branches that have grown less than 8" in a year to the next outward-branched lateral limb.
If these wordy instructions have you confused, I'm not surprized. I personally wouldn't want to prune a tree without some diagrams! Your extension service or local library will likely have some books or other information.
