I am sorry for this delayed reply to your gardening question. The spring rush has brought a deluge of questions and we are working hard to catch up!
There is not a way to kill a grass out of a grass lawn. You can let it go dry in summer which would favor the bermuda over the fescue. Crabgrass can be prevented with preemergence herbicides applied in early spring before the weed germinates. Your County Extension Office can provide product suggestions and the best timing for your area.
Thanks for the question. Best wishes for a wonderful gardening season. Please stop in again soon!
