Abstract: Methods, devices and compositions directed to the delivery of a preferably organic formulation of plant nutrients to indoor and outdoor potted plants, cut flowers, vegetable, herb, and flower seedlings, and other types of plants. The methods, devices and compositions form a simple, safe, non-toxic, cost effective and easy to use delivery system comprising the use of a plant nutrient composition. The plant nutrient composition is typically dry and is maintained in a plant nutrient delivery system during storage and shipping. When ready for use, the plant nutrient composition is contacted with hot water to release the plant nutrients retained within the plant nutrient composition, and the resulting infusion is cooled, and then administered to the plants.
