after all my searches i'm still not sure on the best time to FIRE UP P.Grasses.The wildlife that appreciates the shelter will be left to hibernate until end of March. My concern is the rain, After burning to a stump is there a risk of the whole thing rotting due to,say, a wet period of a week ? I'd like to do it asap but i'd wait if there's a risk of losing it. Thanks for your comments.
