Spring-flowering plants should be pruned immediately after they have finished flowering in spring. This timing is critical because many of these plants bloom on wood that developed in the previous year. Pruning them right after they flower allows for the removal of spent blooms and promotes healthy new growth for the following season, without sacrificing the flower buds that would form for the next spring's bloom. If pruned too late, such as before the bloom or at the end of summer, it could compromise the plant’s flowering potential by cutting away the buds that were developing as a result of last year's growth. This practice also helps maintain the shape and size of the plant while encouraging vigorous new growth.
