In most parts of the country, trying to keep yards watered throughout the summer requires an open tap like you haven't seen since your last fraternity kegger. Which isn't so great if you live in a conservation-conscious area that restricts sprinkler use. If the best defense is a good offense, the way to beat the heat is with micro irrigation. This system of drip tubing and tiny sprayers delivers aqua right at the base of plants.
Setting up a system to feed a backyard's worth of plant beds, shrubs, and trees takes just a few minutes of designing and a couple of hours of connecting components. See How to Install Drip Irrigation
