Abstract: A torroidal outer ring is positioned with a plant coaxially thereof, wherein the torroidal outer ring includes ring segments securable relative to one another in an end-to-end relationship receiving spikes between ring segment junctions to secure the rings together and to an underlying ground surface. A cylindrical trough is directed about a top wall of the ring member, including apertures to direct fluid therethrough. A central insert is positioned medially to the top wall, including a fertilizer to be dispersed through each interior cavity of each ring segment to the underlying ground surface.
