Abstract: A fertilizer spreader includes an attachment assembly for use with a portable hand-held air blower for entraining granular fertilizer or the like into the discharge air stream of the blower, whereby the fertilizer is broadcast by the air stream over a lawn or garden area. The attachment assembly comprises an adapter nozzle connected in-line with the discharge air stream of the blower and including a pressure port through which a portion of the discharge air stream is directed for passage through a pressure tube to a diffuser mounted within a portable vented fertilizer-receiving container near the bottom thereof. The diffuser turns the air stream upwardly within the container and divides the stream into a plurality of turbulent air flows for agitating and suspending particles in a localized region above the diffuser, with a substantial portion of the air stream escaping from the container through a vent at a position remote from the localized region.
