Frequently asked questions
How deep should topsoil be?
For overseeding or leveling, 1 to 2 inches is common. New planting beds often need 3 to 6 inches; follow the needs of your plants and existing soil.
Should I order bags or bulk soil?
Bags are convenient for small jobs. Compare the rounded bag cost with a bulk-delivery quote for larger areas, including delivery and a little extra for settling.
