The Beginner’s Guide to Topdressing: Smoother, Healthier Lawns in Emsworth & Arundel

Bumpy lawn? Thin in places? Topdressing with the right mix can transform structure, drainage and look; here’s how….

Topdressing is a thin layer of sandy loam/compost brushed into the grass to level, improve drainage and feed the soil. Done after aeration or overseeding, it’s one of the fastest ways to make a lawn look and feel better.

What to use

• Sandy loam/root-zone for most West Sussex lawns (improves drainage on clay).
• 3–5 mm depth across the surface; up to 10 mm on localised dips.

When to do it

• Spring (active growth) or early autumn (warm soil + seasonal rain).

How to apply

1. Mow, then aerate.
2. Spread evenly with a shovel or spreader.
3. Brush in with a lute or stiff broom until you can just see leaf tips.
4. Overseed beforehand where thin; water to settle.
