Preparing a Filled Pond Site for Lawn

A UK homeowner filled a 15×4 ft pond with 2 ft hardcore and 2 ft topsoil, then compacted it by watering and rolling. Asked if re-digging and adding compost is needed before turfing.

Yes, Amend and Loosen

1. Spread 3–4 inches compost, grass clippings, or leaves.
2. Till into top 6 inches.
3. Test pH; target 6.5 for turf.
4. Monitor fertility—"topsoil" often lacks clay and nutrient-holding capacity.

Clay Importance

Some clay in the root zone retains water and nutrients. If absent, plan for frequent, light fertilization.

Loosening the compacted layer is essential for root penetration and drainage.
