An adjustable attachment for a landscaping air blower includes a mounting tube, a nozzle and a connecting ring that rotatably couples the mounting ring and the nozzle. The upstream end of the nozzle defines a circle aligned at an acute angle to the axis of the nozzle and the downstream end of the mounting tube defines a circle aligned at an acute angle to the axis of the mounting tube. Rotation of the nozzle about its axis changes the alignment of the axis of the nozzle relative to the axis of the mounting tube.
