When is the best time for pruning evergreens to avoid damage?

Pruning evergreens in spring or fall is considered the best time to avoid damage for several reasons. During these seasons, the plants are either about to enter a period of dormancy or are just coming out of it. In spring, pruning as the new growth begins allows for the plant to heal and respond positively to the cuts made, promoting healthy growth in the upcoming season.

In the fall, while the plant is still active, it has time to heal before the harsher winter conditions arrive. It’s crucial to avoid pruning in the summer when many evergreens may already be stressed due to heat or drought conditions, as well as risking new growth that may not harden off before winter. Pruning during the winter or when evergreens are dormant can also be detrimental, as these cuts can expose the plant to harsh environmental conditions, freeze damage, or disease during its most vulnerable state. Therefore, targeting spring or fall optimally balances the health of the plant with the timing necessary for successful pruning.
