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. Lawns with overly low soil pH or compacted soil are also prone to thatch. Overfertilization and heavy pesticide use contribute, too. When to Dethatch Your Lawn Always check your lawn's thatch layer before dethatching. Take a garden trowel or spade and dig up a small wedge of your lawn grass and soil.

You'll be able to see and measure its thatch layer. If your thatch is 1—2 inches or more, you've probably already seen signs of poor grass color and weak, thin growth.

Once you've confirmed your thatch exceeds the healthy mark, the time for dethatching has come. Like most major lawn projects, such as planting new lawns or overseeding existing lawns, dethatching should coincide with peak growth times for your grass type. Active grass growth helps speed your lawn's recovery. Dethatch cool-season grasses, such as Kentucky bluegrass, in late summer or early fall. Dethatch warm-season grasses, such as Bermudagrass or Zoysia grass , after spring green-up, as they enter early summer's peak growth.

Never dethatch when your lawn is dormant or stressed; you can damage it beyond recovery. Lawn aeration and dethatching are two different processes, but they can work together to help your lawn. Aeration removes cores of soil, including their thatch layer, and creates paths for water and nutrient to penetrate thatch and compacted soil.

This helps prepare thatch for removal and speeds the breakdown of existing thatch. Dethatching helps slice through thatch into soil and remove the barrier of thick, accumulated organic matter. How to Dethatch Your Lawn If your thatch is over 2 inches thick, you may want to consider hiring a professional for the job. If DIY is more your style , you can dethatch your lawn in three ways: Manual dethatching rakes are heavy, short-tined rakes with curved blades designed to dig into your lawn and pull up thatch as you rake.

Dethatching rakes are good for light thatch and general thatch maintenance on small lawn areas. Power rakes are mower-like devices with rotating, rake-like tines that dig into thatch at the soil level and pull it up. Power rakes work well for lawns with thinner thatch layers and grass that can withstand intense raking. Vertical mowers , also called verticutters, have vertical blades that slice down through the thatch layer and into soil, pulling thatch—and often grass roots—to the surface as they go.

Verticutters are best for thick thatch layers on lawns in need of renovation. Blades adjust to control how much thatch you remove at once.
