Power raking or de-thatching is the #1 way to eliminate the problem of excessive thatch build-up.
It is important to power rake when there is enough growing season left for your lawn to recover from the treatment because it does cause some damage to healthy grass.
Power ranking is a great way to remove dead debris and crust that builds up on the lawn over Winter. Thatch is a layer of dead grass that settles near the roots of the lawn. If left alone, it can smother the grass, making it hard for sunlight and water to penetrate the ground.
