Lawn Care Tips – Thatch

A healthy lawn contributes to your property value and the overall appearance of your neighborhood. It provides a natural, safe surface where your family can play and relax. By following a few simple tips, you can keep your lawn healthy and environmentally beneficial.

Thatch: Thatch is a layer of dead and living shoots, stems and roots that builds up between the green vegetation and soil surface. Because thatch has high lignin content, it resists microbial breakdown.

Thatch will accumulate if the growth of the crowns and lateral stems (rhizomes) exceeds their decomposition. If thatch builds up to a thickness of more than 1/2 inch, it restricts water penetration and minimizes the movement of air and fertilizers into the soil. It weakens the turf, which makes it more susceptible to insect, disease and weed invasion.

Older lawns that have been highly maintained with excessive nitrogen applications and over-watered may be unhealthy because of a thatch problem. You can easily check this by cutting a plug of grass and soil several inches deep and examining it. A dense layer of spongy vegetation and organic (peat-like) material between the crown of the grass plants and the soil of more than 1/2 inch will indicate that your lawn needs to be dethatched.

Relieve thatch problems by aerating. This is done with a core aerator, which punches small holes to a depth of several inches, pulls out cores and leaves them on the surface. Leave the cores on the surface to dry, then crumble and spread them with a hand rake or by dragging a section of weighted chain link fence across the aerated area.

If it is set deeply, a vertical mower (power rake) may remove thatch but it will also damage the grass crowns (growing points). When the thatch layer is thick, most of the roots will be in the thatch. If that’s the case, a vertical mower will pull out most of the live grass. Only a small amount of healthy turf will be left and you’ll need to topdress and reseed the area. If a vertical mower is set shallow enough to leave the live grass undamaged, it does little more than remove dead grass clippings that will breakdown anyway.
