Here’s some advice for those of you growing fruit trees. August is the best time to do summer pruning. If you haven’t already done so, thin out shoots and crossing branches. This allows more air and light into the tree, reduces disease and promotes earlier ripening of the fruit. Remove most water sprouts. These are the soft, fast growing shoots usually growing straight up. Cut them back to a main branch. If you need to fill in a spot in the tree and there’s a water sprout growing there, cut that one back to about 2" and it will promote a fruiting spur.
Pruning fruit trees this month controls the size of the tree and can also prevent rampant sprout growth next spring. That’s because pruning removes many of the little food factories ( leaves ) that supply energy to the plant and store it, to be used for growth in the spring.
Prune to maintain a vase shape. By promoting upright limbs high in the tree and pruning hardest in upper and outer portions, fruiting wood is maintained throughout the tree. Also eliminate limbs growing inward. Remember never to prune more that 1/4 of the total mass of your tree at any one time and no more than 1/3 per year. Better to space out corrective pruning over 4 years if your tree has gone too long since the last pruning.
One last thing, fertilize your trees one more time. Most established fruit trees need their first application when the tree begins to emerge from dormancy in the spring, another after fruit set and the third immediately after harvest. For young trees in the first, second or third growing season, apply at half the rate.
Feed your trees and they’ll feed you.
