This Mixer/ Sprayer uses fertilizer or insect spray for your lawn or garden. It is automatically mixed with water and applied by hand with the sprayer head on the right.
A more convenient method may be to fasten the optional yellow Timer to the faucet, fasten a hose to the male fitting on the right, and apply the solution with a power Sprinkler. Then you can set the optional timer and do other chores while the Mixer and Sprinkler do the solution watering.
When you buy one, make sure the sprinkler head fitting has standard garden hose threads. Also get one with an "O"- ring gasket for the container. And remember to store them where the sun, mice, wasps, and spiders cannot damage them.
