Unfortunately, there really aren't any options for selective post emergent control of broadleaf weeds in sedum or most ground covers. The chemicals that would eliminate the weeds would typically also harm the ground cover. You will need to carefully spot treat or hand pull the existing broadleaf weeds, and use a weed preventer in spring and fall to help keep them from coming back. Gallery 75 DF or Isoxaben 75 WG would be the best choice as a pre-emergent if you are targeting broadleaf weeds in a sedum garden or in a cool season lawn.
