How to Control Lawn Thatch?

Thatch is a layer of living and dead tissue that grows between green vegetation and soil. It is mainly made up of products from stems, leaf sheaths, crowns, and roots resistant to decay. A small layer of thatch improves the wear tolerance, but too much thatch makes the lawn more vulnerable to disease and drought.

Checking For Thatch In Your Lawn

To figure out how much thatch has built up in your lawn, cut a two-inch-deep, pie-shaped wedge out of the lawn. Then, measure the gap between the soil surface and the green plants. One-half inch and under is usually fine. On the other hand, if the layer is more than one-half inch thick, you should start mowing services in Adelaide.

Controlling Lawn Thatch

Thatch control may include both preventing and getting rid of it. Preventing too much thatch should concern homeowners and turf managers who want to keep their lawns in good shape. A lawn-mowing program should be thought about if more than one-half inch of thatch is on the ground.


If you keep your lawn trimmed so that only one-third of the leaf height is cut each time, you do not need to bag the clippings. Grass clippings that are small enough to fall into the grass quickly decompose and return nutrients to the lawn. However, the clippings must be spread out evenly and not piled up in clumps.

There is no need to use a mulching mower to let clippings fall back to the lawn, but mulching mowers spread clippings far more evenly than standard mowers do, so you don’t have to. However, doing this does not make it more often than you need to cut the grass. The growth rate of the grass determines how often the lawn needs to be mowed. 

Water for Optimal Root Growth

One of the leading causes of thatch is bad lawn care, such as not watering enough or applying too much quick-release nitrogen fertilizer. These practices encourage too much growth.

Lawn mowing and gardening services are essential to keep thatch at bay. For roots to grow deeper into the soil, you need to water them often but not very profoundly. Infrequent, deep watering promotes good root growth.

There are a lot of deep, whole roots in grass that make lawns thick and green, keep them from drying out, and keep weeds from taking hold. This happens at least once a week; water about 12 inches. When you start lawn mowing services, put a small can on the ground and start. As soon as the can is whole enough, stop adding more water. If you have an automatic irrigation system, make sure that it is set up to water your lawn in the right way.

Take Soil Tests Occasionally.

Take soil tests every few months to keep an eye on nutrient and pH levels. Most soil test labs recommend how much lime to add to the soil to make it more acidic so that turf can grow well and microbial populations can break down thatch.


Core aeration is an excellent way to keep thatch from growing in the first place. Regular core aeration relieves soil compaction and allows more air to get into the soil, which leads to more activity that is microbial and the breakdown of thatch. This also means that thatch is physically removed.

Good turf growth, density, and Greenup can only happen if enough fertilizer is used. However, it should not be so much that thatch builds up at a rapid rate. Also, only use fungicides and insecticides when getting rid of pests. Using pesticides that do not hurt earthworm populations will make it more likely that thatch will break down faster.

Regular lawn mowing and gardening services eliminate the need to rake thatch. Make sure that the controls for the mechanical rake are set correctly before you use it. Afterward, the lawn may not look good. Adding seeds to a lawn may be needed to fill in bare or thin spots that need to be filled in.

Usually, when thatch layers are an inch or thicker, preventative measures will not be enough to keep them under control. In these cases, you must remove thatch by hand. Use vertical mowers with blades on the same level as the turf surface to cut down on the grass. As the machine moves over the turf, the rotating blades cut into the thatch, causing organic debris to be thrown up into the air. You can set the blades on vertical mowers at different depths, which lets you control how much thatch you remove.
