A growing trend in sand topdressing of putting greens - both warm (C4) and cool (C3) turfgrasses – is to consider the total amount or volume of sand applied for the season. This total would include the sand used during coring operations (filling core holes). Regardless if you core frequently or not, or sand topdressed frequently the total amount of sand applied for the year should remain the same.
For ultradwarf bermudagrass greens the total amount of sand recommended for the year is given in Table 1. The range depends on the climatic conditions present. The longer the growing season the greater amount of sand that needs to be applied. If possible, always favor the high end of the range.
The type of sand should meet USGA (United States Golf Association) specification. If possible use dry sand since it is easier to work into the ultradwarf turf. Do not use course sands because they are difficult to work into the turf canopy and prone to be mowed off. Verticutting and grooming prior to sand topdressing is not effective for working sand down into the turf. The most effective means is to brush the sand in. Additionally, rolling prior to mowing will help move sand into the canopy.
