Lawn diseases are not always easy to diagnose. Some key factors and symptoms to help recognize disease include: size and shape of dead and dying plants, specific spots on leaves, quality of root system, leaf color and growth characteristics, time of year, and temperature when disease developed. When diagnosing a lawn disease it is helpful to have a record of treatments such as fertilizer, herbicides, mowing height and frequency, watering frequency and amounts. Grass disease can ruin a lawn’s appearance. However, good turf management practices can prevent serious damage.
