Planting Grass After Stump Grinding: Acidic Debris, Lime, and Soil Replacement

Restoring Lawn Where Trees Were Removed

Stump grindings (chips + soil) can be acidic and nitrogen-poor, but rarely prevent grass entirely.

Remediation Options

1. Remove & replace – Excavate 12" deep; bring in quality topsoil. Best results.
2. Amend in place – Spread lime (50 lb/1000 sq ft); add compost; till 6-8".
3. Test first – Cheap pH kit confirms if lime needed.

Grass Establishment

• Use starter fertilizer (high phosphorus).
• Seed at recommended rate; roll lightly.
• Keep constantly moist 2-3 weeks.
• Mow high (3") first season.

Tree-Specific Notes

• Pine/oak grindings = more acidic.
• Walnut = juglone (inhibits some plants); avoid sensitive species.
• Most hardwoods = neutral to slightly acidic.

Lime is cheap insurance. For large areas, soil replacement ensures uniform stand.
