Good topsoil is the foundation of a healthy lawn or garden. It provides the nutrients, drainage, and structure that plants need to establish strong root systems. When adding topsoil, look for screened, loamy soil that crumbles in your hand. Avoid anything with large clumps, rocks, or visible debris.
For new lawns, spread 2 to 4 inches of topsoil over the prepared grade, then rake smooth before seeding or laying sod. For topdressing an existing lawn, apply a thin 1/4-inch layer after core aeration. This fills the holes and improves soil quality over time without smothering the grass.
The key to buying the right amount is knowing your exact area. Use LotSite to measure the area you plan to cover. Paint it on the satellite map and the square footage adds up as you go.
