What sort of weeds are you talking about - these just grew, mostly buttercup though I think. How about cursus compost then, a nice mix of grass and weed with a few twigs thrown in. Cursus logs from the tree that fell down - now thats an idea, it would save me having to shift it. Any takers? You could even mow your own grass and weed mix lol (lawnmower supplied, bring your own petrol) I might even throw in a cuppa.
