Black Plastic Under Mulch--Yes or No?
In Virginia, I put down thick black plastic sheeting to cover an entire bed, cut holes in the plastic wherever I wanted to plant something, covered the plastic with mulch and then just watered occasionally through the holes. I also had a soaker hose beneath the plastic in one bed which worked well. The plastic held in moisture and controlled weeds. Does that work here, or would it get too hot under the plastic and kill the plants?
