When Will Hardy Mums Bloom Again?

Hardy mums planted last spring will bloom again in late summer or early fall. To ensure a bushy, flower-packed plant, pinch back the top 2 inches of each stem in late May or early June. This triggers side branching and more flower buds.

Otherwise, mums are low-maintenance. Water deeply during dry spells (two weeks without rain), and they'll reward you with a spectacular autumn display. No need to dig them up — they're perennial in New Jersey.
