Pruning cherry trees at different times of the year has varying effects and requires specific techniques. Dormant pruning typically occurs from mid-November to early March of the following year, lasting about 140 to 150 days. The best time for pruning during dormancy is as late as possible, ideally when buds are approaching the middle or late March. Pruning too early can lead to prolonged wound exposure, increasing the risk of water loss, which may negatively impact growth in the following spring and, in severe cases, even cause branch death.
During the dormant period, the main goal of pruning is to establish a strong, high-yielding tree structure and develop robust fruiting branches. Most of the pruning involves one-year-old shoots and young perennial branches. Common techniques include short cutting, slow release, and shrinking to control growth and encourage fruit production.
Growth period pruning usually takes place after shoot development and harvesting, focusing on thinning or shaping the canopy. It's essential to consider the characteristics of each cherry variety. For example, sweet cherries have an upright growth habit, vigorous saplings, and weak branching. Their fruiting branches are often clustered, and excessive pruning can weaken the tree’s vigor. When pruning young trees, it's important to moderately shorten them to promote branching and increase fruiting wood. Trees with a central leader should be carefully pruned to maintain balance, open up branches, and remove competing limbs.
Once the tree enters full fruiting, soil and water management should be strengthened, and light pruning should be used to stimulate growth on the top of fruiting clusters and rejuvenate the tree. Large purple cherry trees tend to have a more open structure, strong branching, and better ability to maintain vigor after heavy fruiting. During the sapling stage, dense or overly vigorous branches should be removed, while moderate branches and weaker ones should be lightly pruned to encourage balanced growth.
During shoot growth, it's important to pinch out the tips to control excessive growth, promote branching, and encourage flowering. The natural spreading shape is ideal for these trees. Throughout the shaping process, maintaining balance between branches is crucial. Divergent or uniaxial growth patterns should be encouraged, with attention given to developing fruiting twigs on both sides of the main branches. Once the tree is fully productive, light pruning at the tips of main branches and two- to three-year-old fruiting branches helps rejuvenate the tree and shift fruiting outward. If the main branches become weak, they should be shortened to stimulate latent shoots and allow for partial renewal.
To eliminate dense one-year-old branches, they should be cut back to the base and then removed entirely. When pruning older branches, make sure the wounds are small and smooth, avoiding pile-up to speed up healing. Avoid upward-facing cuts, as they can lead to poor healing, rot, and hinder overall tree health.
