My garden is on heavy clay and produces a large amount of perennial weeds including various grasses and lots of creeping buttercup. Because the soil is wet it is not possible to shake it from the roots of the weeds. So I end up with a big heap of weeds and soil. Is there any way to kill the weed material in the heap so the soil can be reused? What about covering the heap in black plastic for a year?
