If you are short on labor, you can use a triplex mower in one direction and hand mow in the opposite direction, or even double mow with the triplex units. 4. Light Topdressing — If the turf is healthy and the tempera- tures are not too high, it is per- fectly fine to apply light sand topdressing to smooth the sur- face. Many superintendents refer to this as "dusting the greens" with approximately 0.1 to 0.3 cubic yards of sand per 1000 sqare feet every two to four weeks. Topdressing should be sus- pended at the first sign of turf stress or if temperatures are ex- pected about 90 degrees F. 5. Grooming — Groomer at- tachments are great tools to im- prove the quality of cut and green smoothness, especially at in- creased mowing heights. The groomers can be used on a fre- quency of two to three times per week as long as the turf is ac- tively growing. This is another practice that should be sus- pended at the first sign of turf stress. 6. Rolling—Putting green roll- ers have proven to be very effec- tive tools to maintain surface smoothness and slightly in- crease speed without negatively impacting turf health. The roll- ers should only be used two to three times per week to avoid abrasion injury.
