Restoring Lawn Over a Former Pool Site with Clay Soil

Yes, you can grow grass over the clay left from a removed pool. The key is soil amendment.

Steps

1. Till in 2–3 inches of organic compost.
2. Add 1 inch of coarse sand to improve drainage.
3. Blend thoroughly to 6–8 inches depth.
4. Seed or sod; keep evenly moist until established.

Native clay is fine—just don't compact it. A soil test from your extension service can fine-tune pH and nutrients.
