An adjustable nozzle is attachable to the end of a garden hose and is also attachable to a separate product container, for example, a bottle containing a garden fertilizer or a bottle containing a cleaning soap concentrate. The adjustable nozzle receives a flow of water from the garden hose and dispenses a product from the container attached to the nozzle. The nozzle has a simplified construction with a reduced number of component parts and the operation of the nozzle is simplified yet enables a user to selectively discharge a flow of water or a mixture of water and product from the nozzle, to control the ratio of water to product when the nozzle is employed in dispensing the mixture of water and product, and to direct the discharge as a stream or disperse the discharge in an upwardly or downwardly directed fanned spray pattern.
