Careful pruning of a pear tree improves the yield of fruit produced by allowing more sunlight to reach the center of the tree, increasing air circulation and supporting the health of the tree. Late winter pruning produces the best results.
Poorly timed or performed pruning of a fruit tree increases the potential for injury at the pruning site, opens a vector for disease and stimulates undue vegetative growth. Training a pear tree entails gently anchoring branches to produce a 60 degree minimum angle between the branch and the trunk of the tree. This practice prepares the tree to bear the weight of maturing fruit. Training also increases sunlight exposure and air circulation, improving the health of the tree and the fruit yield it produces.
