A self-contained and low-maintenance two-piece planter providing significantly extended self-watering time for plants in an upper member supported by a fluid-containing lower member. An exterior indentation on the bottom perimeter edge of the upper member engages a small interior ledge positioned near the top edge of the lower member to provide a stable and readily-separable connection between upper and lower members. The upper member's bottom surface supports a fill-tube and has perforations covered by fluid-permeable material, and at least one wicking member is positioned on the material with an end extending through one of the perforations. Plants may be in pots supported by the upper member, or plants may be rooted in a growth/support medium distributed therein. No municipal power or water supply connections are used. Applications include, but are not limited to, daily self-watering of plants in residential homes, shopping malls, commercial buildings, hotels, convention centers, and college campuses.
