A plant irrigation dispenser and method controllably dispenses nutritional compositions to a plant. The dispenser comprises a housing defined by a first end and a second end that forms a channel. Impaling members form at the second end of the housing. The housing encloses multiple chambers that contain the nutritional composition. The chambers have a filling end and a dispensing end that forms an opening. A membrane seals the opening. Rotatably manipulating and axially displacing the chambers in relation to the housing allows the impaling members to tear the membrane, so that the nutritional compositions flows through the openings, and onto the plant. A press is in communication with the chamber cavities, so that axially displacing the press in a downward direction forces the nutritional compositions through the openings. A valve assembly retains and manipulates plugs in alignment with the openings to selectively couple and decouple the respective openings.
