There are several lawn maintenance steps you can take to prevent brown patches from occurring: ● Aerate your lawn to improve soil drainage and increase air circulation. ● Dethatch to remove any dead grass and debris buildup and dry out the fungus. ● Reduce your watering schedule to prevent overwatering. ● Improve drainage in lawn areas prone to standing water, such as low-lying or near downspouts. ● Avoid mowing over the location of the brown patch, as this can further damage the grass and spread the fungus.
