Frequently Asked Questions
How much topsoil do I need for a new lawn?
For new lawn installation, use 4-6 inches of quality topsoil. A 1,000 sq ft lawn needs about 12-18 cubic yards of topsoil for optimal grass growth.
What makes good quality topsoil?
Quality topsoil should be screened, have 40-60% sand, 20-40% silt, 10-20% clay, 3-8% organic matter, and a pH between 6.0-7.0. It should be dark, crumbly, and free of weeds.
When is the best time to apply topsoil?
Early spring or early fall are ideal for topsoil application. Avoid applying when soil is muddy or during extreme heat. Allow 2-3 weeks for settling before seeding.
Should I test my topsoil before applying?
Yes, test pH and nutrient levels before large applications. Most plants prefer pH 6.0-7.0. Add lime to raise pH or sulfur to lower it if needed.
How do I prepare the area for topsoil?
Remove weeds and debris, rough grade the area, ensure proper drainage, and lightly till existing soil 4-6 inches deep to prevent layering.
