Abstract: The plant watering trellis apparatus provides both a trellis for plant support and a plant watering means. The collection tray is sized with a width about equal to the top width of the apparatus so that rain collection is also an option, as well as hand or automated filling from another source. Transparency of the vertical supply tubes allows a user to visually determine the water level within the apparatus. Legs are inserted into a given soil for apparatus support. The valves in the delivery tubes control drip and rate of drip from the delivery block orifices so that monitoring water supply to plants is needed only at the outset in determining best plant water supply. After setting, the apparatus can be conveniently left unattended. The delivery blocks are relatively heavy so the delivery tubes are downwardly extended. The planar apparatus is easily located and used.
