Question
One of the lawns I take care of has a bad case of bentgrass in all different sections of the yard.  I aerated and overseeded it last year, and I think that made it worse.  I know I have to kill the bentgrass and the regular grass that is close to it, but should I kill the whole yard to make sure I get it all, or should I kill just where I see bentgrass?


Answer
You've got the right idea, but just kill the bentgrass, not the whole lawn.  Ironically, I just published a column on this very topic that you can read by following the link below.  It answers it pretty much exactly.

Please don't hesitate to follow up if you have any other questions.  Thanks for writing!
