Abstract
A lawn and garden feeding apparatus includes a container made of transparent plastic, having inlet and outlet hose connections and a disposable cartridge which is inserted into the container. The cartridge comprises a gel with plant nutriment and a water soluble dye suspended therein with the cartridge fitting the inside of the container and having a bore communicating with the inlet and outlet connections. The container inlet is connected by a garden hose to a source of water and the outlet is connected by a hose to a conventional sprinkler or nozzle so that in use of apparatus, water flows through the cartridge bore drawing nutriment and dye from the gel in micro-feeding amounts, and is discharged through the sprinkler or nozzle. Extraction of dye from the gel, after a selected period of time, results in a perceptible change in gel color, indicating that the cartridge requires replacement.
