If you recall, thatch is something I have addressed in these course updates on a few occasions previous to this one. Most all of the problems we have with health and playability to all of the turfgrass surfaces here at Granite Bay can be directly correlated with the development of excessive thatch.
This situation did not just develop, it has been accumulating for years, but it is imperative that we reduce its current accumulation mechanically if we are to have playing surfaces we can be proud of. It starts there. Not aggressively removing it for the sake of keeping surface disruption to a minimum will not serve any of us well, both now and in the future.
