I have a major issue with this plant. I can't get rid of it. What have you guys used to get it out off shrub beds. The stuff comes in the mulch of all things. It could be a great money maker to have a solution. I have put down Snapshot at heavy rates, it only slows it down a bit. I want it gone. Need some info on this one guys. Thanx. And by the way, its horsetail, not horseweed or mares tail.
