When to Use Topsoil vs Garden Soil
Topsoil and garden soil serve different purposes. Topsoil is screened native soil used for grading, filling, and establishing lawn areas. It’s affordable in bulk but lower in nutrients than garden soil or compost. Garden soil is amended with organic matter and nutrients for planting beds.
Use topsoil when you need to fill low spots in the yard, level areas before seeding a new lawn, or build up grade around foundations. Use garden soil or compost for flower beds, vegetable gardens, and raised beds where plants need nutrient-rich growing medium.
Topsoil Depth by Application
| Application | Recommended Depth | Notes |
|---|---|---|
| New lawn over existing soil | 2 to 4 inches | Spread over rough-graded subsoil before seeding |
| Top-dressing existing lawn | 0.25 to 0.5 inches | Thin layer, overseed on top |
| Filling low spots | Varies | Fill to match surrounding grade, compact in 4-inch lifts |
| Replacing poor native soil | 4 to 6 inches | Remove existing soil first, or till together |
Ordering Tips
Bulk topsoil is sold by the cubic yard. One cubic yard weighs roughly 2,000 to 2,500 pounds depending on moisture content. A standard pickup truck bed holds about one cubic yard (do not exceed your truck’s payload rating). For larger quantities, have it delivered and dumped where you need it.
Always ask your supplier if the topsoil is screened. Unscreened topsoil contains rocks, roots, and debris that make spreading and raking difficult. Screened topsoil costs slightly more but saves significant labor.
