How I would manage bentgrass greens today

In this presentation, I discuss the work that can be done to get the best possible bentgrass. I explain how the greenkeeper can make site specific adjustments to produce the desired bentgrass surface, with a focus on how the previously-discussed factors that influence turfgrass growth can be used in everyday greenkeeping work. I explain how I managed greens 15 years ago, when I was a greenkeeper, and how I would do the work differently today.
