Learning how to dethatch your lawn will help you to control the level of excess plant matter among the grasses. In particular, dethatching enables you to remove some of the thatch layer, which is a natural build-up of decaying grass between the roots and shoots.
Thatch often promotes lawn health – but when the thatch layer accumulates to a depth of over ½-inch, it can block the flow of water and fertilizer to the roots, causing dehydration and malnourishment of the grass plant. This is where dethatching can help.
