You didn't say the type of liriope you had. I have used 1% roundup over the
top of certain varieties of liriope. This does not apply to variegated
varieties. Also try using a sponge or rope wick applicator to apply to
grass that is taller than the liriope.

Would appreciate any suggestions on selective herbicides that work
well to remove grasses invading Liriope (Monkey Grass). We have
an especially heavy invasion of stilt grass this year, it grows
everywhere. Will the typical grass killers like Poast or Grass-B-Gon
work on this grass, and spare the Liriope? I am almost at the point
of wiping it ALL out, if it gets the stilt grass too..
Thanks
