I live in Charlotte, NC and have a Bermuda 419 soccer field in the backyard and tall fescue in the rest of the yard. I thought my biggest problem was going to be keeping the bermuda out of the fescue, but it has turned out to be uncontrollable spread of the fescue into the bermuda. What is the best way to keep the bermuda free of fescue? I use separate lawn movers for each...a rotary mower for the fescue and reel mower for the soccer field. The soccer field gets a lot of sun and I routinely mow it to about 3/4 inch. My landscaper...who is nowhere to be found now...said something about "sanding" the field each year. Scotts Lawncare comes and sprays fertilizer for broadleaf weed control but has offered no help regarding the fescue problem. Thanks for any help you can provide...
