When should I cut back weigela?
The best time to prune it is right after it’s done flowering, which is late May into early June. It’s not too late to prune it now, but I wouldn’t wait much longer because the plant will begin producing flower buds for next year shortly. You can really whack weigelas back if necessary.
Do you cut down weigela in the fall?
Prune weigela in the late fall or early spring.
You can prune the weigela before it blooms to promote more flowers this year or after it blooms to promote stronger growth during the next blooming season. Weigela should not be pruned after mid-July.
