Will this kill snow on the mountain (bishops weed)?

I have very invasive bishops weed next to my garage and it is making its way into the lawn. I am looking for a way to kill this terribly invasive weed which is taking over my little yard! Thank you.


Bishops weed is very difficult to get rid of.  Weed Impede is not labeled to get rid of Bishops Weed specifically, so we are not sure if it will work or not.  From everything we have read online, it is very difficult to eradicate. We did find this online: The only way to get rid of Bishops Weed is with a lot of patience and time on your knees weeding it out of your garden. Bishops Weed likes to grow in the top 4 inches of soil, so don't dig too deep when getting it out. You are bound to miss a few rootlets which will start sprouting again. Just dig them out as they show up, and be persistent! Edging can be useful as you weed the garden area, as it will allow you to work smaller areas at a time without worrying about re-infestation from surrounding areas (weeds love that nice fluffy soil) You can try a heavy dose of Round-Up in early fall before the weed goes into its winter dormancy.
