A tree frame and grate system having a liner and growing method for the purposes of encouraging healthy and abundant root growth and permitting optimal development and growth of a tree or other plant material within an urban or otherwise primarily paved environment. The system is comprised of a preformed supporting frame to contain an engineered growing media and plant material. A liner is provided to create a barrier between the system and the media within and/or surrounding the system and that of native or adjoining soils. The frame may also support a manufactured grate or other partial enclosure. The system may be adapted for electrical service connection for aesthetic lighting, and piping to provide supplement irrigation.
