Establishing Grass on Rocky Soil: Don't Just Bury Rocks with Topsoil

On a 12,000 sq ft cleared site full of rocks, owner considers removing large rocks and adding topsoil over the rest. Expert advises against layering different soil textures—creates watering nightmares and root barriers.

Better Approach

• Remove large rocks.
• Till existing soil (rocks and all).
• Rake smooth.
• Sow appropriate grass seed at correct season.
• No added loose soil to wash away.

If desirable tree roots are present, adding soil over them kills trees. Minimum 8 inches of uniform soil needed for turf—but it must match native texture.
