Preventing weeds before they begin will keep a flowerbed attractive and full of healthy plants. Not only will weeds detract from the appearance of a beautiful garden, but they also encroach on your desired plants, stealing nutrients in the soil. A plastic liner laid securely over the top of the soil of a flowerbed will smother the weeds you want to prevent, leaving the plants you do want to grow and thrive.

Cut the plastic sheeting to cover the soil area of the flowerbed. If you have existing plants already growing in the flowerbed, cut slits in the sheeting with the scissors to lay the sheeting around the plants and carefully fit the plastic sheets around the plants. If you do not have plants already growing in the flowerbed, lay the plastic sheeting over the entire flowerbed, overlapping the sections by 2 to 3 inches to ensure complete coverage.

Make “Xs” in the sheeting with the scissors where you wish to plant flowers. Fold the flaps of the sheeting back to expose the soil beneath the plastic and dig holes for the flowers with the trowel.

Plant the flowers in the holes and cover the roots of the plants with soil. Tamp the soil down lightly with your hands and replace the flaps of the sheeting around the flowers to cover the soil.

Place between 2 and 3 inches of wood chips or gravel over the plastic. The mulch will hold the plastic down and it will also cover it to make your flowerbed more attractive.
