Any of you have horsetail weeds in your area? Man, they are the worst. When they take over a planting bed - I mean REALLY take over - like get inside the shrubs and everything - I don't see any option other than just killing off everything in the entire planting bed (including the shrubs that have been taken over) and starting over again from scratch. I just hate the stuff. Crossbow seems to do a good job of killing it. But again, usually it's inside all the groundcovers, plants, etc. I can't figure out what to do other than just kill everything effected and start over. Any ideas? Experiences?
