Caring for Autumn Joy Sedum: Divide or Cut Back?

When to Divide

Divide Sedum ‘Autumn Joy’ only when clumps become overcrowded or messy—typically every 3–4 years. Spring is the best time; dig the clump, split into sections with roots, and replant. Extras can be composted or shared.

Seasonal Cut-Back

• Fall: After flowering, cut stems to 6–8 inches if desired for tidiness.
• Late winter/early spring: Remove all dead growth to ground level before new shoots emerge.

No Need to Divide Annually

If the plant looks healthy and isn’t crowding neighbors, simply cut back in late winter. Division is only for rejuvenation or propagation.
