Urban drool is the water that runs off improperly watered lawns, carrying fertilizers, pesticides, and valuable nutrients to ground water, local streams and the ocean, causing potentially devastating bacterial and algae blooms and chemical pollution.
To avoid urban drool, think of how a dry sponge absorbs less water than a damp one. Urban drool can be prevented by watering with hourly pulses of short durations that give the soil enough time to absorb the water.
