Pruning Guidance
Pruning Time
Late spring (after insect emergence)
Pruning Method
Cut stems to 8–24 inches in spring
Chop-and-drop
Wildlife Benefits
Seedheads provide winter food for birds
Standing stems support overwintering insects
Cut stems retained at 8–24 inches support insect habitat
Pruning Notes
Leave stems and seedheads standing through fall and winter. Birds eat the seeds, and insects shelter in and on the stems. In late spring, after several nights above 50°F, cut the old stems to 8 to 24 inches at varied heights. Bees and other insects nest in the cut stubs the following summer. Lay the cut tops loosely in the bed so insects still inside can emerge.
