In the summer is it important o keep your lawn mowed higher than is needed in the winter months. As temperatures increase the longer lawn will create a more shaded and cool area for the roots, thus creating healthier roots. Tall fescue lawns should be cut to 3.5 inches, blue and rye grass should be cut to 2.5 inches and bentgrass and Bermuda lawns should be cut to 1.5 inches. Additionally, with longer lawn length you will not have to water as much to keep the lawns healthy and green. The longer grass will allow water to absorb more slowly. It is important not to overwater because it can lead to disease in your lawn. Overwatering may lead to foreign invasion of weeds and other grasses in your lawn. Therefore, it is vital to adjust your sprinklers to avoid dry spots, without overwatering the entire lawn.
Additionally, in early summer aerations may be very beneficial for lawns. Throughout the year your lawn is likely to build up a layer of dead grass below the live grass and on top of the soil, this layer is called a thatch layer. Thatch layers are harmful for a variety of reasons, such as limiting water absorption, blocking nutrients and even creating a desirable place for June bugs to lay their larvae. Aeration is a great way to break down this thatch layer and promote a healthy lawn.
