What You'll Need

✓Wheelbarrow
✓Flat-back shovel or spade
✓Landscape rake or garden rake
✓Tiller (for new beds)
✓Garden hose or sprinkler
✓Lawn roller (optional, for lawns)
Step-by-Step Instructions
- 1Calculate how much topsoil you needMeasure your area in square feet and decide on depth. Use our topsoil calculator for exact cubic yards. Order 10% extra to account for settling. Plan your delivery — topsoil is heavy (1,400–2,000 lbs/yard), so make sure your access is clear.
- 2Prepare the existing soilFor new garden beds: till the existing soil to a depth of 4–6 inches. This breaks the "interface layer" — a hard boundary that roots struggle to cross. Remove rocks, large debris, and any remaining plant material. For lawn top-dressing: skip tilling; mow the lawn short first.
- 3Spread topsoil in 2-inch layersNever dump all your topsoil in one pile and spread it. Add in 2-inch layers, working across the full area before going deeper. This gives you better control, prevents compaction, and allows you to till each layer in. For depths over 4 inches, alternate between tilling and adding.
- 4Rake to even depthUse a landscape rake (flat side) to pull topsoil into a consistent, level layer. Work in long, steady strokes. Check depth with a ruler or stake at several points. The finished surface should be about 1 inch below walkways and edging, since topsoil will settle.
- 5Compact lightly and water thoroughlyWalk over the area or use a lawn roller to eliminate large air pockets. Don't over-compact — just firm it. Water the entire area thoroughly until the top 4–6 inches are moist. This initiates settling and bonds the new topsoil to the existing soil below.
Depth Guide by Project
| Project | Depth | Notes |
|---|---|---|
| Filling low spots in lawn | 1–2 inches max at once | Reseed if grass is covered |
| Top-dressing existing lawn | ½–1 inch | Rake into grass, no tilling needed |
| New lawn from seed | 4–6 inches | Till existing soil first |
| New flower or vegetable bed | 4–6 inches | Mix with compost for nutrients |
| Raised bed fill | 8–12 inches | Use blended mix: 60% topsoil + 30% compost |
Common Mistakes
- ✗Adding too much at once: More than 2 inches per layer creates an air gap between old and new soil. Roots struggle to bridge this. Always layer.
- ✗Skipping soil preparation: Dumping topsoil onto hard, unworked ground creates a sharp interface. Till or at least loosen the existing surface.
- ✗Not watering immediately: Dry topsoil blows and shifts. Water the same day you spread, even if rain is coming.
- ✗Spreading on wet ground: If the existing soil is saturated, wait. Adding topsoil to wet clay traps moisture and causes compaction.
