    Abstract: A plant supporting arrangement or totem upon which the roots of growing plants can attach and receive nourishment and water in appropriate quantities is provided, which comprises at least one generally cylindrically shaped perforate frame, having at least one open end, and designed to be utilized in a substantially upright position. A suitable barrier is operatively associated with the perforate frame and this barrier serves to prevent soil placed inside the perforate frame from passing through in any quantity.
