A plant watering system comprises a porous inner pot at an elevated location within a water-impervious outer container. Water within the outer container wicks by capillary action up the side walls of the porous pot and wets any soil or like medium contained within the inner pot. The lower part of the inner pot is coated with a water-impervious layer to control the elevation at which the wicking water may enter the soil. Also, a special pot liner enables gases to be bi-directionally vented throughout a selected region in the bottom of the inner pot. When desired, water may be drained out the bottom of the inner pot. The inventive process adjusts the percentage of moisture maintained by soil, or the like, by rating the moisture needs of plant species, the season of the year, and the type of growing medium used. Such a process enalbes a plant grower to select a preferred level of water in the outer container, and therefore the distance over which the water must travel by capillary action through the porous wall. That distance regulates the amount and rate at which the soil is replenished with moisture.
