Overseeding Patchy Bermuda Grass with Common Hulled Variety in South Carolina

Assess the Cause of Thin Areas

• Shade: Bermuda needs 6+ hours sun. Prune or accept thinness.
• Iron deficiency: Light green/yellow = iron. Apply chelated iron.
• Different cultivar: Patch may be different Bermuda type. Overseeding blends eventually.
• Compaction/clay: Aerate, topdress with compost.

Overseeding Steps

1. Mow low (1 inch) and bag clippings.
2. Core aerate.
3. Spread common hulled Bermuda at 1–2 lbs/1,000 sq ft.
4. Topdress ¼ inch compost/sand mix.
5. Water 2–3x daily until germination (7–10 days).
6. Mow at 1.5 inches once 2 inches tall.

Organic Boost

• Sugar: 1 lb/250 sq ft spring/fall.
• Organic fertilizer monthly (8-2-4).
• Low frequent mowing encourages lateral spread.

Source Verification

Buy seed from reputable local nursery, not box store. Ask for germination test date and purity. Local knowledge matters.

Timeline
