Abstract
Self-watering plant container includes a container used to hold a living plant and soil and a container to hold a pool of water or nutrient solution underneath the plant/soil container where the water may be absorbed by the living plant through a permeable bottom in the plant/soil container. Self-watering plant container includes an airspace layer located between the bottom of the plant/soil container and the top of the water or nutrient solution pool in order to prevent excessive moisture or water from being absorbed into the plant/soil container, thereby preventing root rot. Self-watering plant container achieves this partly by special funnel shaped root-pruning aeration apertures in the bottom of its plant/soil container that allow very small roots and root hairs to grow through the bottom of plant/soil container and into the water reservoir below, while forcing larger roots back into the plant/soil container, and also allowing for aeration of the plant/soil container.
