We just moved in to a old cottage that has been empty for a year the inside is now sorted but the garden is a complete and utter mess. Its over grown with stinging nettles and weeds what would be the easiest way to clear it. I've cut them down but I now need to get rid of the roots and creepers. I seem to remember an old uncle using a "flame thrower" to clear weeds would this be a good method?. Any help would be great.
