Project Tips
Long Island's native soil is mostly sand — it drains fast and lacks nutrients. Adding 4-6 inches of screened topsoil before seeding gives roots the organic matter they need. For existing lawns, a 1-2 inch top-dress improves soil quality over time. Mix topsoil 50/50 with compost for vegetable gardens.
