Many lawn care experts believe that a majority of our lawn care problems are a result of not mowing at the proper height...and not keeping our lawn mower blade sharpened throughout the mowing season. Each type of grass has its specific height for optimum performance. Mowing to keep the grass at its best growing height will increase your lawn's density and attractiveness, and reduce lawn care problems. No matter the kind of grass you have, there is a simple "rule of thumb" to follow when mowing your lawn. Never remove more than one-third (1/3) of the leaf surface each time you mow. Leaf surface, or cutting height, refers to the length of grass above the soil. Cutting below the optimum height impedes root development, which is key to having a dense, healthy lawn. Use the following chart to determine the best growing height for your kind of grass and when to mow it again.
