Weeds also can be discouraged by using weed barrier fabrics available in many Garden centers. Anchor fabric edges with U-shaped wire pins about 6 inches long. Plant through slits cut into the barrier. Put a decorative mulch on top of the fabric. Avoid using plastic film for a weed barrier.
Plastic films prevent weeds, but they also tend to suffocate plant roots.
