Winter can be an ideal time to prune most trees and shrubs
It can enhance the health, vigor and aesthetics of your trees and shrubs throughout the whole year.
Here are just a few of the benefits of winter pruning.
During the winter, most woody plants are dormant and so are the many diseases and insects that can potentially invade pruning cuts. After leaves have fallen, it is much easier to see the plants overall form and structure. Damaged and diseased branches are more readily apparent when not obscured by foliage. Pruning in the late summer or early fall can stimulate new growth that may not harden off before the cold weather. This is not a concern during the winter. Winter pruning is good for your plants, leaving them with extra root and energy reserves to quickly heal wounds and support vigorous spring growth that will obscure the pruning cuts. Pruning when cold reduces the oozing of sap from fresh cuts. Loss of sap from the tree results in a reduction of vital energy potentially limiting the trees chance of healthy future growth.
More specifically, two trees that benefit most from winter pruning and why.
Oak trees:
In the case of oak trees they too should be pruned in winter. This is due to a specific odor that emits from freshly cut branches, subsequently attracting a type of beetle that causes oak wilt. Oak wilt is a fungal disease that is brought into the host tree via the beetle. This is a serious disease that often kills the tree, and symptoms include leaf discoloration, wilt and defoliation. These beetles hibernate in winter, hence the benefit of pruning in winter while the oak trees are dormant.
fruit trees: Fruit trees should only be pruned while the tree is dormant. This will significantly reduce the likelihood of contracting diseases such as fire blight and stem canker. It also promotes vigorous spring growth and larger, better tasting fruits to be enjoyed the following year.
