Topdressing Low Spots in Lawn: Avoid Soil Layering Problems

Critical Rule

Use the same soil type you already have. Mix with organic matter (leaves, clippings, compost) and till into existing soil 6 inches deep to create a uniform blend.

Timing

Any time, if you seed immediately to prevent erosion. Off-season? Sow annual ryegrass—it dies in spring and won't compete.

Existing Grass

Some grasses survive burial, some don't. Till it in anyway—it becomes organic matter.
