1) Inspect the lawn
- Check for a thick layer of thatch (over ½ inch) made up of dead grass, roots, and debris between the soil and green blades.
- Thatch buildup can block air, water, and nutrients from reaching the roots.
2) Mark hazards
- Identify and mark sprinkler heads, shallow irrigation lines, and delicate landscape features to prevent damage during dethatching.
3) Select equipment
- Use a dethatching rake for small areas or a power dethatcher/verticutter for larger lawns.
- Choose the appropriate blade setting to lightly cut into the thatch without tearing healthy grass.
4) Dethatch systematically
- Work in straight, overlapping passes across the lawn for even coverage.
- For heavy thatch, make a second pass at a right angle to the first.
5) Collect debris
- Rake up and remove the loosened thatch and debris from the surface to allow air and sunlight to reach the soil again.
6) Post-dethatching care
- Water the lawn thoroughly to help recovery and settle loosened soil.
- Overseed and fertilize if needed to encourage new, healthy growth.
- Avoid heavy traffic until the lawn has visibly recovered.
7) Schedule regular maintenance
- Dethatch every 1–2 years, or as needed, to prevent excessive buildup and keep the lawn healthy.
