ABSTRACT:
A double-walled plant pot has a single water-permeable bottom, a permeable inner side wall, and an impermeable outer side wall. The space between the walls is filled with a fertilizer mixture whose concentration of fertilizer increases with depth. Thus larger plants obtain more fertilizing nutrients. The inner wall, bottom, and outside may be separable.
