The presence of lawn thatch gives turf an uneven look, and once the new grass starts growing, it is very difficult to de-thatch. Secondly, the thatch prevents fresh grass from getting adequate water supply as it forms a water proof layer choking the stem of the grass plant and preventing it from getting water from its roots. With lack of adequate water supply, grass can turn an unhealthy shade of yellow and its sickly appearance will be compounded by all those pests which love to attack sick plants.

Another alternative is `coring’ which is done by using machines called coring machines. Coring machines create cores or holes in the ground as they drill out thatch. The open holes allow moisture to enter; this helps in preventing further decomposition of any thatch that might still be buried underground.

Once de-thatching is completed, it is wise to apply a soft layer of soil, which will help enable microorganisms to penetrate the ground and destroy any remaining hidden thatch.
