Soil Preparation for a New Lawn: Compost Incorporation and Slope Stabilization

Compost vs. Topsoil

Landscaper warned compost brings weeds. But topsoil is just "soil on top"—no quality guarantee. It can be weed-infested subsoil. Mix 2 inches of compost into the top 6–8 inches of native clay. This improves structure, drainage, and microbial life.

Weed Prevention

• Use weed-free compost (hot-composted).
• After tilling, rake smooth, water to settle, re-rake—repeat until surface is perfect.
• This "stale seedbed" technique germinates weed seeds; hoe them off before planting grass.

Slope Erosion Control (5 ft rise over 50 ft)

That's a 10% grade—significant runoff risk.

• Seed netting (erosion blanket) holds seed and soil.
• Retaining wall or terracing is even better for long-term stability.
• Hydroseeding with tackifier is another option.

Free compost is a goldmine—use it wisely. Proper prep now prevents headaches for years.
