The ground under our apple trees is covered in ivy and I can't seem to keep on top of it. I want to lay membrane over the area and woodchip it - I've raked up all the fallen leaves and most of the ivy too, but not dug it over as the ground is full of roots and hard to get to under tree branches. If I lay membrane over the bits of ivy that are left then peg down and woodchip over the top, the ivy will just die and go away right???? Or am I being totally stupid? How bad will it be?
