Sheep, they’ll eat just about anything green and sometimes brown. They are not as all inclusive as goats, but one can use foraging as a tool.
Take the grape vine with an invasive hardy kiwi for example. We had meant to get it all cut back last winter and start over. I think the sheep have done a wonderful job. But, do we need taller sheep or shorter vines?? Oh, and they are mowing the back yard, too.
