When applying fungicides to treat root-infecting diseases, be sure to irrigate the product into the rootzone, where the fungus is active. Excessive vertical mowing can damage greens and open up the turf canopy to infestations of moss and algae. Use consistent, good quality Use particle SGN (size freezing temperatures. High quality, uniform overseeded putting surfaces are routinely obtained with a minimum loss of play. There is no one-size-fits all program for ultradwarf management, but these practices are fundamental to produce high-quality surfaces for 49 weeks of the year allowing a few weeks for the necessary disruption of aeration. Again more frequent light applications of sand affect play less, and ensure that the most sand possible stays in the plant canopy and does not get picked up by mowers.
