The best way to prevent disease is to keep your lawn healthy through proper watering, mowing at the correct height and through regular fertilization. Despite your best efforts, however, disease can find a way to creep into your lawn in the form of brown patches and circles.
Even the healthiest looking lawns can fall prey to a variety of turf diseases. Although certain kinds of grass are more susceptible to lawn diseases than others, most plant diseases are caused by fungi, which can spread by air, water, and animals. Factors such as humidity and cold weather can create breeding grounds for fungi growth.
While no one likes to discover that their lawn is suffering from disease, it’s important to catch the warning signs early to keep it from spreading.
