This week we look at part four of USGA agronomist, Pat Gross’ December 2010 report on the greens at the Villages. This week Pat's report addresses sand topdressing.
Sand topdressing - Routine applications of sand topdressing will be a critical aspect of your program to control thatch and organic matter and enhance the firmness of the greens. A demonstration of the current light sand topdressing procedure was done during the visit, and it was suggested to increase the rate of application and continue to apply topdressing at two-week intervals. Topdressing should be suspended when temperatures exceed 90° F. or after several days of heavy frost when there is very little growth evident on the greens. Light topdressing can be incorporated with practices such as vertical mowing, spiking, and venting of the greens to help incorporate the sand into the surface.
