A planting dish has a dish body with a central hole and two plate members. Each plate member includes inner and outer edges, first and second side portions, a top surface defined by the inner and outer edges and the first and second side portions, and first and second securing members on the respective first and second side portions. The top surfaces cooperatively form a conical top surface that slope downward from the outer edges to the inner edges. The first side portion of one of the plate members is removably juxtaposed with the second side portion of the other plate member, with first securing member on each of the plate members being releaseably engageable with the second securing member on the other plate member.
