When should I divide perennials in New Jersey?

Spring-blooming perennials should be divided in early fall, from September through October. Summer and fall-blooming perennials are best divided in early spring, just as new growth appears. Divide every 3 to 5 years to rejuvenate plants and control their spread. Water divisions well after replanting and mulch to protect roots.

Why It Matters

Dividing perennials keeps plants healthy, controls their size, and gives you free plants to expand your garden or share.
