I was at one of my premium and noticed many circular blotches of dead grass in his lawn, some were 1" diameter and others ran up to 5". Closer inspection revealed that the ends of the dead grass were frayed and looked as though someone had sprayed them with red food coloring. The lawn is a bluegrass/red fescue blend and is under a maintenance program by Lawn Doctor. I'm familiar with "rust" that appears here later in the season, but this is something different. I also noticed the same condition on my own lawn today, although not as severe. The photo below is some of the dead shoots I pulled, if you look closely at the center, you'll see the red tint. We've had an unusually high amount of rain this season and had a hail storm last week with quarter sized pellets, if this might matter. Does anyone know what this condition is and how to correct it? Thanks!
