Common Causes Of Thatch Build Up

PleasantGreenGrassAs of now, lawn owners experience numerous issues that ruin their lawns from pest infestation, lawn stress up to discolouration. Apart from that, there are also some owners who experience thatch build up.

Thatch build up begins when turf produces organic debris faster than it can be broken down. As a result, it can store heat that can burn plants. Not to mention, this build up can also affect air circulation on the soil which limits plant growth. To know more, below are the common causes of thatch build up.

Thatchy turfgrass species

Some turfgrass species produce a lot of stem tissue as rhizomes or stolons, which form more thatch than others. These species include Kentucky bluegrass, creeping red fescue, and creeping bentgrass.

Acid soils and reduced microbe activity

Another cause of thatch build up is acid soils and reduced microbe activity. Reduced microbe activity is primarily caused by large amounts of clay or sand on the soil as well as compacted soil.

Pesticides

Pesticides are important in helping make lawns appealing and safe. However, multiple applications of some fungicides over a 2- to 3-year period can increase thatch compared to untreated areas. Other than that, some insecticides influence thatch development through their effects on earthworms such as reducing its population.

Aggressive fertilization

Thatch can accumulate quickly following aggressive nitrogen fertilizer programs. Nitrogen promotes thatch development because it increases production of root and stem tissues.
