Weed Suppression With Ground Cover
I looked around for this topic but so far did not find it. I have used black plastic, landscape fabric and cardboard to suppress weeds prior to planting. Laid out over a good "crop" of weeds the soil turns black and crumbly and has earth worms running through it. The landscape fabric or black plastic can have holes punched in it and be planted through thus eliminating much of the need for weeding. Black plastic also keeps deer at bay - the slippery surface frightens them. While having deer around is a fancy problem you do not want to compete with them in a garden. Question: how much toxicity slips out of cardboard, black plastic, or even landscaping fabric into the soil?
