You'll need three to six inches of topsoil for new lawns, depending on your soil's condition. If your soil is poor, aim for closer to six inches. Garden beds require about eight inches of topsoil. The best approach is to till two to three inches into the existing soil before adding the rest on top.
To prepare for your dirt, sand, or mulch delivery, start by selecting an accessible area with flat, hard surfaces like concrete, asphalt, pavers, or gravel. Ensure the delivery route is clear of obstacles such as landscaping features or power lines. Have someone present during the delivery to address any issues immediately.
To determine how much topsoil you need for your landscaping project, calculate the project's area and desired soil depth. A 40-pound bag covers 12 square feet at a one-inch depth. Multiply your square footage by the desired depth (in inches), then divide by 12 to determine how many bags you need for even coverage.
