Bermudagrass is the most common putting green grass in hot climates and cultivated dwarf varieties are believed to play as well as creeping bentgrass. The advent of growing issues with water quality has led to the establishment of a sizeable niche market for seashore paspalum.
The other main warm season turfgrass, zoysia, has mostly been ignored as a putting green grass though its use has increased as a fairway turf with excellent shade tolerance, high disease and pest resistance and low resource needs. Japan is an exception to this rule, where korai (scientific name Zoysia matrella, also known as manilagrass) has long been one of the grasses of choice for putting surfaces because of its excellent adaption to the humid subtropical climate of East Asia. The putting surfaces at the Kawana Hotel’s Fuji Course, for example, are korai.
Now, from Dr Micah Woods of the Asian Turfgrass Center, comes further evidence that zoysia can present high quality putting surfaces. In a short video, he introduces korai greens as used at two well-known Japanese courses: the aforementioned Fuji Course and Keya Golf Club in Fukuoka.
Using the R&A Holing Out Test, the Keya Golf Club greens achieved 100% reliability with every ball from 10 feet running straight into the cup. “We couldn’t miss”, was Dr Woods’ reaction.
