Question of the Week 08/29/2020

Q: Should I dethatch my lawn every year?

A: It depends on how thick the thatch is. Thatch is a layer of both living and dead grass and organic material that creates a mat between the soil and grass. Thatch has the important role of insulating the grass roots from extreme temperature changes, conserving moisture and protecting the grass.

However if the thatch gets more than 3/4" thick, it can lead to numerous problems that can damage and limit the growth of your lawn. The best time to dethatch depends on the type of lawn you have.

For cool season grass dethatch in early spring or early fall; for warm season grasses, late spring through early summer.
