Abstract: A house plant hospital comprises a closed container in which a potted plant may be positioned and covered by a hingedly-attached lid. A plurality of lights are mounted within the container, while the plant may be occasionally rotated by being positioned upon a "lazy susan" support. In an alternative embodiment, provision is made for supporting several layers of plants and a water spray system is also provided. Additionally, fertilizer and pesticides may be sprayed over the plants while they are retained within the container. The closed container positionable over the plants operates to retain heat provided by the artificial light source so as to prevent the plants from being damaged in a cold environment.
