What makes greens speed? Is it just shaving the down the greens? Is it really that simple?

Greens speed isn’t that simple. Height of cut does play a role, but shaving down the greens is not the only factor. Green speed also depends on many other factors and the consistency of maintenance programs – some of these are mowing frequency, rolling, topdressing, soil moisture management, verti-cutting, growth regulators, and fertility. Green speed is also a function of weather and turfgrass variety. Because of all the necessary programs, green speed also depends on a lot of person power. Green speed is something that must be planned for, not just “made”. And not just accomplished by green height.

When we plan for a tournament, preparations to produce a target green speed begin at least six or more weeks in advance. All the programs are increased to peak the greens at the time of the tournament. If we have timed every thing correctly, the greens will top out at tournament time, and be healthy enough to recover from the stress incurred. The longer we maintain them in this manner, the weaker they become due to all the stresses put on the plants, which is why the greens cannot be kept at tournament speeds at all times. Even US Open and Master’s greens don’t stay fast for very long...
