Abstract: A plant pot drainage system has a pot or planter-type container with potting soil. Lightweight, non-mineral rock shaped filler elements are located in the lower section of the container. The elements are irregular in shape, allowing the potting soil to fill spaces between the elements. This promotes drainage and proper root growth within the container. The elements are formed from synthetic, crush-proof material, for example high strength plastic, and can be hollow, to enhance the lightweight nature of the elements. Use of these filler elements ensures that the planted container can be easily lifted and readily transported.
