Abstract The plant cistern of this invention comprises a cover portion and a cistern portion. The cover portion includes an inclined dish issuing downwardly at an angle to an upstanding shield portion in the centermost portion of the dish. Adjacent the upstanding shield portion are a multiplicity of entranceways through the dish. The cistern portion includes a bowl having a downwardly projecting tube-like protector portion at the centermost portion thereof and a cake fabricated from a soil admixture, such as compound peat moss and plant nutrients, disposed in the bowl. The cake generally conforms to the bowl, and is provided with sloping wall adjacent the uppermost terminal edge of the bowl, the wall issuing downwardly at an angle to an entranceway through the centermost portion of the cake.
A plant cistern comprising a cistern portion having an upstanding sidewall, a bottom wall integral therewith, said bottom wall being downwardly inclined from said sidewall and terminating in a vertically depending flange forming an opening in said bottom wall for plant growth therethrough, a body of compacted plant nutrient material in said cistern portion having an aperture vertically coaxial with said bottom wall opening, a cover portion resting on said cistern portion and generally covering the same, said cover portion being downwardly inclined from the periphery thereof to an upstanding tube-like shield defining an opening in said cover portion generally centrally thereof and through which said plant growth may extend, said cover portion having entranceways therethrough adapted to admit water into said cistern portion.
