Think of it as an intensive deep-clean for your grass. It’s not raking leaves; it’s using a machine (or a manual rake with blades) to slice into the lawn’s surface. This yanks out the “thatch”—that nasty layer of dead stems, roots, and moss that builds up between the soil and the green blades. If thatch gets too thick (over half an inch), it’s like your lawn sleeping on a mattress made of old sponges.
It blocks water, air, and nutrients from reaching the roots. Your grass then gets lazy, weak, and moss takes over. Ever seen a lawn that’s all squishy but looks sick? That’s a thatch party, and you weren’t invited.
