A three-dimensional dynamic plant cultivating apparatus for plant cultivation mainly has an outer cover and a supporting member disposed in the outer cover and surrounded by a rail module. The rail module is further assembled with supporting plates for supporting a plant pot. Upon implementation of the invention, the rail module operates along a periphery of the supporting member, so that the plant pot can circulate upwards and downwards around the supporting member repeatedly and can be subjected to overall irradiation of a sun light source to contribute to growth of the planted material. Furthermore, a plant cultivating device, an illumination device and sensors are further connected together in the outer cover to form a timing-controlled and quantitative automatic cultivation environment advantageous to prompting of the growth of the planted material.
