Ok everyone, grab a cold one and sit down, the kid is about to school you on all things grass/golf. I was pursuing a degree from ASU in turfgrass management as well as working on the grounds crew for one of the best superintendents in the Phoenix metro area at Phoenix Country Club. I know a thing or two about grass. First of all, Ive never heard of what PLAYA is talking about in regards to tilt of the earth. There are most definitely grasses that can grow annually and their growth has nothing to do with the tilt of the earth. One example of this would be BENTGRASS. Bentgrass is a cool climate grass just like RYEGRASSand Fescue. However, growing conditions can be manipulated and bentgrass can be utilized even in the summertime here in Phoenix. That being said, Bentgrass isnt very common in lower elevations especially in the Phoenix area. Bentgrass is generally used on the greens here in the Phoenix area on the few courses that use it. Most of the courses that utilize bentgrass here in the Phoenix area are all up in Carefree. One particular course that has bentgrass greens would be Pinnacle Peak Country Club. Like I said earlier, conditions must be manipulated to grow bentgrass in Phoenix in the summertime, ie. more water and even sometimes using fans to keep the grass cooler. Bentgrass and ryegrass are generally found more in higher elevations, particularly in the Northwest. Flagstaff courses utilize bentgrass as well. Cold weather grasses like bentgrass and ryegrass have very thin leaves and provide the best putting surface. Bermuda grass is used widely in the Southwest, AZ, Inland Cali, Nevada. Hybrid bermuda turfgrasses have been developed specifically for golf courses and professional venues that require grass. There are a few that are used more frequently here in the state of AZ, ie. Ez-turf, tif-green and Tifway 419. Bermuda grass is a warm season grass and therefor will go dormant in cooler months. Bermuda grass will have to be overseeded with Ryegrass for the cooler months if you wish to keep the grass green. Dormant bermuda grass can be kept an off-greenish color if proper water is still applied to the grass in the off-season months. Dormant grass should not be confused with dead grass. Hybrid bermuda grass offer some of best playing conditions in my opinion. Hybrid bermuda grass have smaller and thinner leaf blades and offer an excellent playing surface, especially when overseeded with ryegrass. St. Augustine and Kentucky blue grass can be found in the south and midwest. These types of grass have very broad leaf blades and IMHO dont look as good and arent as good of a playing surface. Poa annua is used in California from San Diego to NoCal. IMHO poa annua resembles a weed and for me is a poor playing surface. Poa annua is another broad leafed turfgrass and is related to blue grass. Poa annua creates a less than stellar putting surface on greens. The courses in Rocky Point use a hybrid turfgrass created to deal better with salt. This turgrass does NOT get overseeded in the fall and therefore becomes dormant when temperatures consistently come down. When you are playing a course in Rocky Point from November or December to about April the turfgrass is dormant. The color of the dormant turfgrass depends on how much water it is receiving as well as how cold or hot it has been. If it is a mild winter and the course if properly maintained then the grass can be a little more greenish gray than brown. Ive played Peninsula de Cortez (Mayan Palace) a few times in the winter and the course has been pretty green even though the grass was dormant. Playing conditions can be excellent on dormant grass. However, I wouldnt count on good playing conditions with the grass being dead at LP.
