Thatch Removal and Aeration—The Underdog Heroes

Even a perfectly fertilized, well-mowed lawn can suffer if soil compaction and thatch build-up choke root growth and water infiltration. Thatch is the layer of undecomposed stems and roots; aeration breaks through compacted zones, unlocking oxygen and moisture.

Dethatching Essentials

• Best window: early spring (March–mid-April) or after summer stress (September)

• Use a power rake or dethatching blade to lift and remove excess mat

• Follow with watering and light fertilization to accelerate recovery

Aeration Techniques

• Hollow-tine aerators punch deep cores, relieving compaction and reducing thatch over time

• Ideal any time soil is workable—spring, late summer, or early fall

• After aeration, spread a thin layer of topdressing or reseed worn patches for optimal repair
