Buying and Storing Organic Topsoil: What You Need to Know

Evaluating “Organic Topsoil” Claims and Storage

You plan to buy organic topsoil and ask about storage, bulk purchase, and whether it equals composted manure.

What’s in it? True topsoil forms naturally from decomposed organic matter and minerals processed by soil life. If it’s a blend of bark, sand, leaf mold, and clay, it’s a soil mix—not topsoil.
Storage: Keep piles covered to stay dry and slow decomposition.
Bulk vs. bagged: Bulk is cheaper but may introduce weed seeds.
Composted manure vs. topsoil: Manure improves texture but has low nutrition; neither should be used alone for planting. Always blend with existing soil.

If improving existing soil, either product works. For raised beds, use a soil mix. Never remove old soil—always blend.
