Creeping Bentgrass can be a problem in home lawns.
Creeping bentgrass (agrostis palustris) was originally cultivated for use on golf course greens. Its main advantage, especially for greens, is that it tolerates extremely close mowing. Unfortunately, if creeping bentgrass is allowed to grow to the proper home lawn height of 21/2-31/2”, it takes on a shaggy appearance and can suffer considerable damage in the Summer.
Creeping bentgrass does not tolerate hot, dry weather, nor cold winters. IT IS NOT DESIGNED FOR NORMAL HOME USE, unless your home is a golf course and you plan on mowing your lawn every other day at 1"or lower and increase your maintenance tenfold.
During the hot summer months, carbohydrate reserves are quickly depleted in bentgrass and the turf may suffer additional stress such as drought, heavy traffic, shade, insects or disease. The only practical use of bentgrass is for golf greens and tees, where small acreage allows for very intense management, full sun and an absolute smooth prepared surface.
Bentgrass grows aggressively during the Late Spring and Fall’s cooler temperatures and usually looks it’s best then. Cool nighttime temperatures are particularly nice for bentgrass. It chokes out the better grasses, Looks it’s worse in late Winter and mid Summer. Bentgrass just does not mix well with other types of grass. Our Summer heat and humidity will always cause it problems. High daytime temperatures and high humidity together with warm nighttime temperatures create very adverse conditions for bentgrass and encourage diseases.
Creeping bentgrass spreads by profuse creeping stolons and usually has shallow roots. Creeping bentgrass is a perennial cool season grass that forms a dense mat. Stem's are decumbent (creeping) and slender and produce long narrow leaves. Leaf blades are smooth on the upper surface and ridged on the underside, 1/8" wide and bluish green in appearance. The ligule is long, membranous, finely toothed or entire and rounded, auricles are absent. Seed of creeping bentgrass are too small to be identified without magnification. Seeds are ovate, less than 1/16" long. Creeping bentgrass is adapted to cool, humid environments. also known as: Carpet Bentgrass, Creeping Bent, Redtop, Redtop Bent, Seaside Bentgrass
