I never thought having dead greens could be so interesting. Extreme circumstances like having to grow in new greens has given me completely different growth rates across my greens. Obviously this isn't great for consistency but it is great for learning stuff and maybe improving for the future. Right now I have highly variable growth rates on my various greens and this can be used to my advantage to see how this different growth rate impacts playability. This week I decided to compare clipping yield to green speed. It's a limited data set and I will continue to collect it into the future to get better data but the first set of results is pretty interesting but not entirely surprising. Please remember that there are a million variables involved here. Grass type, cultural practices, height of cut, roll or no roll all can impact the ball roll. I think this will have to be measured on each course and for each cultural practice to figure out what is best for your course. Also note th...
