I have stripes of dead grass where the tires of my lawn mower run on my san augustine. Is it possible that the tires can kill grass?
Other possible causes are driving repeatedly in the same track or allowing mowed grass to collect in a "wind row" which will smother the grass.
thanks, guys. I tend to think the water issue is the main problem. We are in drought here in east tx. and its been hotter than hades for the last month. More water it will be!
