Does anyone know the best/cheapest place to buy weed control fabric (or the black polythene that farmers use) to cover my allotment. We're talking 300 square metres so the cheaper the better. My plan is to cover the plot until next year in the hope that it will kill most things off.

Try E-bay - I bought some off there a month or so back, seemed a reasonable price and cheaper than anywhere else I saw,
