Turfgrass and Lawn Management

What does topdress mean and why is it done?

Topdress means to spread a layer of sand or sand plus organic material over the turf surface. The material is then redistributed by dragging a mat or section of chain link fence to move the sand from the high spots to the low spots. Topdressing evens the surface of the field, helps prevent thatch build up by providing a more favorable environment for microorganisms, and prolongs the effects of aeration by physically preventing hole closure. Topdressing is done routinely on golf greens and is used on sports fields and other fine turf when soil compaction or thatch problems develop.
