How to Divide Perennials: 4 Easy Steps to Revive & Multiply Plants

When clumping perennials become overgrown and bloom poorly, divide them. Each section with roots becomes a reinvigorated plant for the original spot or new locations. Most benefit from division every 3–4 years—larger blooms, lusher foliage. Divide spring bloomers in fall; fall bloomers in spring. In harsh winters, replant 6–8 weeks before hard freeze.

Division in 4 Steps (Using Daylily Example)

1. Loosen & lift: Shovel/fork around base; slide under roots; lift whole clump, keeping rootball intact. (Divide in place if too large.)
2. Clean & separate: Shake/brush off soil. Cut apart with sharp pruners (small clumps) or shovel/spade (large/fibrous).
3. Pull divisions: Separate by hand—each with roots and foliage. Continue for smaller clumps.
4. Trim & replant: Snip damaged roots/foliage. Replant ASAP in amended soil (ground or pots). Water well.
