A non-powered dethatcher is more reasonably priced and is usually dragged behind a lawn tractor or operated manually. A pull-behind unit tears rhizomes and stolons and pulls up thatch with a series of wire fingers that scratch the surface to various depths, depending on the weight applied to it. Dethatching manually is hard work and less effective but is nothing more than vigorously raking the lawn with a hard-tooth rake.

Hot, dry weather could slow it down, but nice weather will get that new grass coming up uniform and vigorous in about a week, he said. In no time, it will look like a new lawn. Keeping the thatch from building up so fast can keep your lawn looking better longer.
It will also keep you from having to rip and tear at it with dangerous machines. Know that some of the most-popular grass species are the most likely to have thatch.
Kentucky bluegrass, for example, grows aggressively and quickly establishes itself. People love it for that reason, but it also means bluegrass produces more thatch. Those are best for areas that see a lot of foot traffic, like sports fields. Choosing or mixing in some perennial ryegrass or tall fescue will cut down on thatch production in your lawn.
Test your soil periodically for its nutrient levels and acidity. Good watering and mowing techniques, and proper fertilization can also hold down thatch. Skip to content.

How to Dethatch a Lawn. You can do your part to manage water usage, and keep your lawn. When you're on a quest for the perfect lawn, you're bound to encounter challenges. These lawn dethatching basics can help understand: What is Thatch? If you've ever seen a cross-section of soil and grass roots, you've seen the layer of organic debris known as thatch. A mix of dead and living plant material, thatch forms at the base of grass plants, where stems meet roots and soil.
Some organic matter, such as small grass clippings or mulched leaves, break down quickly in healthy lawns, but other materials take much longer to decompose. When buildup outpaces breakdown, your lawn's thatch layer grows thicker. A thin thatch layer allows water, nutrients and air to penetrate into soil and reach waiting plant roots.
But when thatch grows thick, grass suffers. Thatch layers of 1 inch or more become barriers instead of benefits. Thick thatch blocks water and fertilizer, and grass roots get trapped in thatch, where they're vulnerable to heat, drought and stress. Water from irrigation can accumulate in the thatch layer, too, so grass roots suffocate from lack of air.
Thick thatch also provides a breeding ground for lawn disease and insect pests. Some lawn grasses are more prone to thatch buildup than other.
Vigorous, spreading grasses such as Kentucky bluegrass , Bermudagrass and creeping fescues, may need regular dethatching. Clump-forming grasses, such as tall fescue or perennial ryegrass , seldom have thatch problems.
