If needed, water the lawn and measure the area before application. Shake bottle well before applying. Connect hose to hose-on applicator. You will need to have a click-on hose connector. Lift plastic flap at front of applicator. Turn on the tap using moderate to high water pressure. Water mixes automatically with concentrate in the proper ratio. Walk and spray lawn at a steady pace whilst sweeping the spray back and forth. Keep bottle upright, do not point directly at the ground. After use, close flap to prevent spillage. Always store upright.
