maybe some one out there knows what to do about this problem I have with a lawn that has some sort of bunch grass growing up faster than i can mow it(the owners only want it once a week). So, the lawn has two kinds of grass, something like a fescue or rye grass that is slowly being overtaken by some sort of bunch grass that I think originated as grass plugs. one of the problems is that I was letting the nice grass(creeping, rye or fescue?) come in from seed and this other stuff got out of control. HELP, WHAT DO I DO TO GET THIS LAWN BACK IN SHAPE!
