Sand topdressing is one of the most important practices for producing smooth putting surfaces and diluting thatch and organic matter. Despite this fact, some courses only apply sand during aeration or infrequently during the golf season to avoid disrupting golfers and dulling mower blades and bedknives. The consequences of an inadequate topdressing program may not be observed immediately, but eventually there will be significant negative impacts on playability and turf health. This article will provide recommendations on sand selection, topdressing rates and application frequency to help ensure that your topdressing program delivers the best results.
