The guinea pig idea is good, but you can cut out the middleman. Make them a cage with no bottom and stick it where ever you’d like them to munch on weeds. Move to a new spot as needed. Unless guinea pigs can dig, then use a couple chickens like we did. No more weeding, ever!
I do sympathise, I really, really do. I live on 20 acres and I’m trying not to use sprays, so I’ve spent countless hours in the last few months pulling and slashing and cutting thistles and other kinds of weeds from my good pasture. I’ve done so much weeding I go to bed and dream about thistles, and at one stage I was getting cramps in my hand from so much weeding.
It got to the stage where I saw each thistle as some treacherous entity, crouching malignly in the grass waiting to spill its load of lethal seeds as soon as my back was turned. Anyone watching would see a middle-aged woman quietly pulling weeds, but inside I was Ripley doing battle with evil vegetation.
