I run about 12 - 15 service calls a day. While I'm currently treating 5 or 6 lawns per day for annual white grubworms, other lawns seem to have "fungus problems" (especially leaf spot/melting out) -- basically on lawns that are currently being mowed at 2 1/2 inches or less--some as low as one inch! Seems "short-mowed lawns" are yellowing - especially in high spots & weed-eating at 1/2 inch, etc. I'm mowing my lawn at 3 1/2 inches (measured after it's mowed), and I have none of these yellowing problems??? Anybody else now seeing this on Kentucky bluegrass lawns?
