The present invention discloses a planting container structure including a planting container containing culture soil for cultivating plants, and a solid fertilizer container containing a solid bone-based fertilizer and inserted in the culture soil. The solid fertilizer container comprises a body part and a tapered part jointed together. The tapered part has a hole, through which the solid bone-based fertilizer seeps into the culture soil to provide base manure for the plants. The solid bone-based fertilizer substantially seeps into the culture soil so as to prolong its usage time. Therefore, the present invention provides a suitable solution for encouraging the eco-environmental treatment of the dead pet through a tree-burial.
