Is the pruning window closed?
Avoid pruning spring-flowering trees and shrubs. The window for pruning any spring-flowering trees or shrubs without impacting next year’s bloom is now closing. I tend to recommend July 4 as an easy date to remember to stop all pruning for anything that is early spring–flowering.
I always say make sure you research the specific needs of any plant before you start pruning.
Does anyone else have any pruning rules they live by?
