Thirsty Lawns and Smart Irrigation
Keep these things in mind:
Twice a week or less: If you're watering more than 2 days a week, you're watering too much.
Don't water between 10 am and 6pm: up to 30% of the water we spray on lawns during the heat of the day is lost to evaporation.
Water by the drop: Use drip irrigation for trees, shrubs, and flowerbeds. Drip systems put water in the root zone - that's right where the plants need it. And adapters make it easy to covert from spray to no drip.
