Overseeding Centipedegrass: Timing and Technique

A gardener asked if centipedegrass should be overseeded and whether to aerate first. The expert said: don't overseed with ryegrass in winter, but you can overseed with centipede seed in June. Aerate heavily, broadcast seed, drag chainlink or carpet for soil contact, water frequently for 10 days, and hand-pull weeds.

Centipedegrass is slow to establish; June seeding gives it the full growing season. Avoid nitrogen fertilizer at seeding—centipede is sensitive to excess fertility.

Steps:

• Core aerate thoroughly.
• Spread centipede seed at 1 lb/1000 sq ft.
• Drag for seed-soil contact.
• Water lightly daily for 10–14 days.
• No fertilizer until established.

Patience yields a thicker, more uniform lawn.
