What is causing the splotchy dew pattern on this fairway?
Ok, here is a relatively easy one. What is causing the splotchy dew pattern on this warm-season fairway? Bonus question: what country is this golf course in?
This is bermudagrass (Cynodon dactylon) holding the dew, and zoysiagrass not holding as much dew. In the second picture, the cart path tracks, used with remote-controlled golf carts at so many courses in Japan, gives the country away.
This course was originally planted to Zoysia japonica in the rough and Zoysia matrella on the tees and fairways. In central and western Japan, when a little bit of bermudagrass finds its way onto the course, it tends to spread and spread, and these photos show just how much it has spread, as evidenced by the morning dew patterns.
