Mark Donovan of
HomeAdditionPlus.com explains how to dethatch a lawn and discusses how to
adjust a pull behind lawn dethatcher.
Over time a thick layer of
grass clippings can build up at the base of a lawn. This build up is known
as thatch and after a period of time it can become so thick that oxygen, water
and nutrients can not reach the grass roots.
Consequently, periodically a
lawn should be dethatched to remove the thatch. After dethatching a lawn
with a dethatcher the loose thatch should be raked up. Then the lawn can
be overseeded, fertilized and watered.
