Amending Silt-Heavy Shaded Soil: Topsoil Over Clay

Silt with tree roots holds water; adding clay worsens it. The solution is a topsoil blanket.

Why Not Clay

Clay + silt = concrete-like when dry. Topsoil (balanced sand/silt/clay) provides structure and moisture buffer.

Method

1. Spread 4–6 inches of quality topsoil over the area.
2. Seed with shade-tolerant fescue blend.
3. Monitor moisture—shade slows evaporation.

Tree roots will take what they need; the topsoil supports turf.
