Don’t Kill Your Garden: The Dangerous Mistake of October Pruning

There are a few key considerations when it comes to pruning, primarily the identification of the ideal season. Autumn, contrary to popular belief, is not always the best time for this task. This article explains why some trees and shrubs should not undergo pruning in October.

Understanding Pruning in Autumn

During the cold season, plants adopt a survival strategy that concentrates energy into their roots. For this reason, pruning during autumn may not provide sufficient time for the plant to recover or heal its wounds.

The Importance and Timing of Pruning

Pruning is a vital procedure for plant and growth, but it must be done correctly and at the appropriate time to avoid causing problems.

The timing of the pruning can vary greatly depending on the plant. Some plants are best pruned in autumn, while others prefer late winter or early spring. Understanding these distinctions is the key to maintaining a healthy and vibrant .
