On 14 and 15 December I gave seminars at Tokyo and Osaka, respectively, to audiences of greenkeepers who came for a full-day seminar about turfgrass science. It wasn’t just greenkeepers from those cities, in attendance, however; some greenkeepers traveled all the way from Niigata, Mie, and Yamaguchi to spend a day learning about new developments in turfgrass science that can be applied in their day-to-day work.
