Here are five signs to keep a lookout for. If you notice one or more of these symptoms, your turf might be telling you it\u2019s time to dethatch your lawn.<\/p>
1. Your Turf Feels Spongy<\/h2>

Photo Credit: Juan Rodriguez<\/figcaption><\/figure> A healthy thatch level (half an inch or less) gives your grass a soft, bouncy feeling underfoot. But if things start to feel overly squishy, it could signal your thatch is too thick. <\/p>
When this happens, your lawn can hold on to too much water like a sponge, making things (like lawn mowers) more apt to sink into the ground (e.g., your lawn mower won\u2019t be level and can accidentally cut your lawn too short).<\/p>

2. Your Lawn is Suffering From Diseases or Pests<\/h2>
Thick thatch provides an ample buffet for bugs to feed on and creates a desirable habitat for fungi and other diseases to thrive \u2014 think pests like grubs or chinch bugs or common lawn diseases<\/a> like brown patch or pythium blight. These can cause your grass to turn brown, wilt, and\/or become excessively dry.<\/p>
Note:<\/strong> Another signal you have thick lawn thatch is if fungicides, pesticides, and herbicides aren\u2019t working properly in your lawn. Often, these treatments can get stuck in the thatch, rather than making their way through the soil, and thus, cannot address the problems.<\/p>

If the layer is thin (one-half inch or less), your lawn is in good shape and doesn\u2019t need dethatching. <\/p>
To check your lawn\u2019s layer of thatch:<\/strong> Cut out a 2- to 3-inch segment of turf with a trowel or grass plugger, and measure the thickness of the existing thatch. <\/p>
