Maiden Grass Dying in the Center? Divide & Conquer the "Donut" Effect

Why Ornamental Grasses Form Dead Centers

Many perennial grasses, including maiden grass (Miscanthus sinensis), naturally die out in the center as they age. New growth emerges only at the outer edges, creating a hollow "donut" shape. This is normal, not a disease.

Turn One Clump into Many Free Plants

1. Dig up the entire clump in early spring before new growth exceeds 6 inches.
2. Cut or pry apart the living outer sections – Use a sharp spade, saw, or axe to divide the crown into fist-sized pieces, each with roots and shoots.
3. Discard the dead center – Compost the woody, lifeless core.
4. Replant divisions immediately at the same depth, spacing 2–3 feet apart. Water well.

Best Timing & Aftercare

Early spring (March–April in Richmond, VA) is ideal. Divisions establish quickly with spring rains. Mulch new plantings and water during dry spells the first season. You'll rejuvenate the original planting and gain free plants for elsewhere—or to share.
