How to apply water to your lawn can be just as important as the amount of water you use. If your lawn thrives on 45 minutes of water every two or three days, it will not remain as healthy if you water 15 or 20 minutes every day. Adjust lawn watering to the weather. Following a heavy rain, for instance, skip your regular watering day until the grass needs it again. Teach the family how to turn off an automatic sprinkler system in case a storm comes up during the sprinkling cycle.
More water is dispensed faster with a larger diameter hose.
Sprinklers that throw large drops in a flat pattern are much more effective than those with fine, high sprays, which can be blown about and evaporate quickly. For any small area of grass, water by hand to avoid waste. On steep slopes, try a soaker hose to help prevent wasteful runoff. Adjust your lawn mower to a higher setting. The grass blades grow longer and shade one another, as well as the ground, helping to fight off heat and hold moisture longer.
