My Garden has been left through previous owners to vast amounts of weeds etc. Ive just covered them with the black bags to stop sunlight coming through plus I put a weedkiller down as a double measure. How long should I keep the bags there for and once done do I need to get a digger in to get rid of deep roots or should the damage be over.? If so when can I start re planting and will I need new soil?

    What weedkiller did you use?'

    Some are persistent and will last three years. Glyphosate needs the plant to be in the light so the weedkiller is transported to the roots. It is inactivated in soil.

    Black plastic left on soil for a full year will kill most weeds.
