An rotational shelf garden system and device, including methods of use, are provided. The garden system and device include multiple hanging shelves mounted on a rotatable frame. Rotating the frame positions a shelf at a desired height for the user, wherein the user of the device may perform gardening activities while sitting or standing. Multiple vertically stacked shelves on a rotating frame, each shelf supporting garden plants, greatly reduces the “footprint” of the garden system versus a conventional outdoor garden, increasing the capacity for generating higher yields while using less ground space. The system and device includes a watering system integrated with each shelf.
