Power raking is a dethatching method used on warm-season grasses that tend to build a thick thatch layer. Thatch is the layer of dead and living shoots, stems, and roots that accumulates between the soil surface and the green growth. A power rake uses powered blades to cut into this thatch and lift it out, improving air, water, and nutrient penetration to the crowns.

Bahia grass commonly forms a noticeable thatch layer, and dethatching with a power rake is a typical technique used to remove that buildup and help the lawn recover and grow more vigorously. Fescue is a cool-season grass and generally doesn’t rely on power raking as a routine practice, while Bermuda and Zoysia can be dethatched but the method is most often described in the context of Bahia.
