Thatch Management

Thatch Management

Thatch is a layer of organic material between the green grass and the soil. Thatch is composed of living and dead stems and roots. Leaves make up only a very small percentage of thatch. Sometimes leaves will form a layer of pseudo thatch at the juncture of the thatch and the green grass. It disappears quickly.

European Crane Fly

European Crane Fly

This is an unusual insect in that it causes most of its damage in late winter and early spring as larvae feeding on all parts of the plant. While we think of it as a turfgrass pest it is also active on many ornamental perennials. The historical pattern for this insect is to move quietly into an area where it may develop to very high populations within a year or two.
