So.. we bought our Blessed home about 2 years ago now.. got goats for our 2 acres and now are realizing our pasture is full of thistle!!.. No good for the goats .. and us especially! so.. is i'm wondering if there's some trick somebody has up their sleeve for irradicating these beasts! can't really use an herbicide cuz the goats graze on it.. but it's TAkiNg OveR!!.. also have wild parsnip!! what can i do!??
