Thatch is a brownish layer of organic debris that sits between the soil and the leaves. Having some thatch on your lawn is okay, although an excessive amount acts as a water barrier for the roots. Thatch on a healthy lawn helps conserve moisture and keeps the crown safe from excessive wear. However, a layer of thatch more than 1/2 inch thick will prevent moisture from reaching the roots. Excessive thatch will also create a favorable environment for disease and insects.

When should I dethatch my lawn?

Generally every 2-3 springs or when the thatch is more than 1/2 inch in thickness.
