The only time we grew Jerusalem artichokes the goats kept eating them and finally killed them. They liked them even more than the comfrey, which they could just reach part of through their fence and kept pretty well trimmed. If someone has a patch that has spread out of bounds I would give the goats or sheep (or chickens) free access to it for a while, and I don't think the plants would last long.(posted 8982 days ago)
