Question
What herbicide can I use to spray in liriope that will kill those weeds in and around liriope but no hurt the liriope, if there is something?

Answer
Donna,
Get a product called Grass Be Gone.I believe it is made by Ortho,but not sure. It is hard to find around here but most bigger garden centers carry it. It kills grass around certain plants like Liriope.I have used it myself.The grass will turn brown and then just pull it out.It comes out easy by the root because the product kills root and all.You will have to use it every season though. Go to Google if you can't find it anywhere and type in "Grass Be Gone" as a direct search for the product and how and where to get it.
Good luck on that stbborn grass problem!
