Planning guidance

Common topsoil estimate questions.

How deep should garden soil be?

Many vegetable beds use 8–12 inches of workable soil. New in-ground beds may need less imported soil when the native soil is amended rather than replaced.

Is garden soil the same as topsoil?

Not always. Garden soil is commonly a blend of topsoil, compost, and other amendments. Check the product label or supplier mix before ordering.

How much extra topsoil should I order?

A 5–10% allowance is a practical starting point for settling, uneven grades, and measurement error. Use 10–15% for irregular areas or uncertain depths.

Should I buy topsoil in bags or in bulk?

Bags are convenient for small repairs and a few planters. Around half a cubic yard, compare prices. For one cubic yard or more, bulk delivery is usually easier and more economical.
