Reviving Overgrown Pampas Grass Through Division

When Pampas Grass Declines, Divide and Conquer

Ten-year-old pampas grass clumps that dry up each winter and only partially regrow are simply too old and crowded. The center becomes a mass of dead foliage while only the outer edges stay green.

Division Steps (Best in March)

1. Dig up each clump (get help—it's heavy).
2. Split into thirds with a sharp shovel.
3. Replant each section in a new spot or share extras.
4. Fertilize lightly after planting, again in April and May.
5. Water weekly until June.

The divisions will recover vigor and grow larger through summer.
