Disclosed is a plant growth assembly and method to allow intensive growth of plants or vegetative organisms in earth or soil from seeds, stems, roots or plants. The assembly comprises a container portion, a dispersion portion and a support portion. The container or pot to grow the plants in comprises a top section that contains earth and the plants, and a bottom section for water or liquid fertilizer storage. The top section is above the bottom section and are joined together or separate items. The container portion joins with the dispersion portion that waters or irrigates plants using spray nozzles growing within a plant growth ring within the top section, the dispersion portion comprising an irrigation portion and/or a base portion, the dispersion portion at the centre of the support portion, the support portion encompassing the dispersion portion to support plants. The radially spaced plants around the periphery of the top section grow at an angle rather than vertically while being supported by the stakes or frame.
