Answer to Question 1
The plant organic matter that is not decomposed between the turfgrass and the soil
surface is called thatch. Thatch is caused by an accumulation of excess grass stems,
stolons, rhizomes, and roots in the turf. It is important to note that grass clippings do
not contribute to thatch; rather, thatch is caused by overfertilization. Therefore,
maintaining a moderate fertilization program will prevent thatch.
Answer to Question 2
Clippings should be removed when they do not readily sift down into the turf.
