Reddish brown patches, pock marked areas of tan grass and yellowing. These are lawn issues we are seeing now and have been expecting given environmental conditions this year.
Roughly circular patches of reddish-brown grass, especially in tall fescue lawns, are symptoms of brown patch disease. Kentucky bluegrass is also affected but symptoms are less prominent.
To confirm brown patch, closely inspect individual grass blades in the affected area. Look for irregularly shaped, tan-colored lesions surrounded by a dark brown margin. It is best to do this just before mowing rather than right after mowing or lesions may be removed.
