Winter is the time of year when many people prune their deciduous fruit trees. However, did you know that now is not the right time to prune apricot and cherry trees?
In the past, home gardeners were advised to prune stone fruit trees (cherries, apricots, plums, peaches, and nectarines) after trees lose their leaves and go dormant. However, cherry and apricot trees are more likely to be attacked by certain diseases that can be spread by rain.

Gardeners who prune cherry and apricot trees during winter create wounds that may be invaded by fungal and bacterial canker diseases. Symptoms show up in spring and summer, when infected tree limbs wilt and suddenly die with their leaves still attached, or when bark becomes discolored and limbs produce an amber-colored ooze.
This year, wait to prune apricot and cherry trees until late spring or early summer. For more information about fruit trees, visit The California Backyard Orchard.
