Many lawns across town will experience heat stress with temperatures reaching above 90 degrees in town. Here are some basic tips to help:
Water your lawn early in the morning, preferably before 9am in order to minimize evaporation. Do not water at night whenever possible as this can increase your lawn’s risk of disease. You may also need to water brown areas of your lawn by hand that got missed by sprinklers. Water your lawn 15-30 minutes everyday when temperatures are above 90 degrees for grass that is in full sun. Keep in mind, this does not necessarily apply for cooler days with cloud cover or grass that is in shaded areas. Do not water when we get rain or during times of high winds.
Some signs of heat stress include mowing lines left in the grass, if your grass turns a grayish-blue color, thinness, wilting and brown crispiness. Using soil conditioner is a powerful way to help browning lawns recover. Mow your lawn at a higher length, around 3 inches, to help your grass lock in moisture. When you allow your grass to maintain some length, this creates insulation from the sun and minimizes evaporation.
