In this video, This Old House landscape contractor Roger Cook explains how to dethatch a lawn.
- For small lawns, use thatch rake to comb thatch from grass.
- For larger lawns, use power rake to remove thatch from grass.
- Use leaf rake to collect thatch and place onto tarp; properly discard thatch.
- Spread grass seed across lawn and rake into the grass.
- Use a drop spreader to apply fertilizer and pre-emergent crabgrass control to the lawn.
- Keep lawn moist; water daily if necessary.
