Useful Tips

• Timing: Topdress during active growth; avoid summer heat stress.
• Thickness: 0.25–0.5″ is typical—don’t bury the grass blades.
• Material selection: Compost feeds soil; sand smooths; soil adds organic + mineral content.
• Even spread: Use a level‑lawn tool or drag mat for uniform coverage.
• Core aeration: Aerate before topdressing to improve integration.
• Water‑in: Irrigate lightly to settle and avoid dusty conditions.
