The many grasses of adams pointe



Although we saw 90 degree days late into September, fall is officially here. The sun is at a lower angle, days are getting shorter and overnight temperatures are starting to get cooler. This is all great news for our cool season turf types as they can begin to heal from the summer heat and prepare for winter. Adams Pointe, like many courses, has multiple species of grasses used for it's playing surfaces. The greens and fairways are both cool season bentgrass. The greens are a blend of Cato and Crenshaw bent cultivars while the fairways are composed of Princeville bentgrass. The roughs are mostly a mixture of tall and fine fescues and bluegrass cultivars. The tee box surfaces are a warm season zoysia grass. Mixed into almost all of the course, minus the greens, is a pesky warm season bermudagrass. The course was originally constructed with the bermudagrass and redone in 2004 with the aforementioned turf cultivars.     

As a general rule cool season grasses do most of their growing when daytime air temperatures are between 60-75 degrees. Many factors including disease, too much water and heat stress can kill off turf during the summer months. Every year in the early fall both the rough and fairways are overseeded. Along with areas that have died off or thinned out we also overseed into the bermudagrass that has invaded the fairways. Throughout the year it is a battle for ground, so to speak, between the cool season and warm season grasses. During the spring and the fall the bentgrass has the upper hand and a chance to fill in thinning areas. The opposite is true for the summer and the warm season turf types. Bermudagrass is, unfortunately for us, a very aggressive and quick spreading grass. Overseeding in the fall with bentgrass into the bermuda will introduce new plants and hopefully give the cool season grass a better chance in the fight.
