Reviving Dead Patches in Meyer Zoysia Lawn

Meyer zoysia is a warm-season grass that spreads by stolons and rhizomes. If a section died and hasn't recovered after dethatching, the cause may be grubs, disease, or environmental stress. Here's how to diagnose and repair.

Check for Grubs

Inspect the top 6 inches of soil in the dead area for C-shaped white grubs. If present, apply grubicide (e.g., Scotts GrubEx) in early spring and mid-summer.

Plugging: The Best Repair Method

Zoysia does not establish well from seed. Instead, transplant 3×3-inch plugs from healthy areas into the bare spots on a 12–18-inch staggered grid. Plugs will knit together in 1–2 growing seasons.

Ongoing Care for Zoysia

• Fertilize in early summer and mid-summer only—avoid spring and fall.
• Mow at 2.5–3.5 inches during active growth.
• Water deeply, infrequently (weekly, 2 hours) to encourage deep roots.
• Avoid frequent, shallow watering.

With plugging and proper maintenance, the bare area will fill in completely.
