Simple pruning tips for your fruit trees during the dormant season

All fruit trees must be pruned and trained to enhance fruit production, as the way the tree is shaped will impact fruit yield, fruit size and ripening. In Kentucky, the ideal time to prune fruit trees is in late winter or early spring.

Both newly planted and mature fruit trees must be pruned to maintain size and shape. Here are some easy tips:

• For young trees, pruning to a strong central leader with four to five lateral branches is most common.

• Heading cuts can be done on mature trees to control the tree’s height; thinning cuts can open up the canopy and maximize sunlight and airflow. For older, overgrown trees that need heavier pruning, removing up to 1/3 of the larger branches over several years will help rejuvenate the tree.

• Pruning cuts should be made at the base of the branches, leaving a ¼” to ½” branch collar intact for proper healing. Dead and diseased shoots and limbs should be removed, as well as any shriveled or ‘mummy’ fruit remaining on the tree.

• Sharp pruners or loppers should be used to ensure clean cuts. Sanitize the tool blades between each cut with rubbing alcohol or a 10% bleach solution so as not to spread any disease that may be present.
