Attach the garden hose to the hose end sprayer. Break the tab on the sprayer. Turn water on full strength if you are at standard city settings. Turn the switch on the hose end sprayer to the “on” position in order to begin application. Earth Right sprayers have a regulator at the bottom of the hose. If Earth Right sprays too slowly, remove the regulator. Using a dial sprayer may be preferable for better control and the ability to see what is being sprayed. Use of Dial Sprayer: Use a setting as noted below. I personally use a dial sprayer.
