How to water your garden in the Phoenix, Arizona area
• A low-pressure *drip* watering system. You can get it for cheap at Home Depot, and it's just a way to step down your house water pressure to low pressure to allow a small amount of water to precisely target your plants. Originally, I had *spaghetti tubing* to the plants, but that doesn't work so good, as it gets clogged easily. So I switched over to the tiny sprayers. They're practically invisible, but they're critical to the health of the garden. This is a precision system, which uses very little water, so it's not a *set it and forget it* thing. I check regularly to make sure that the sprayers are working correctly, hitting the plants at the roots. The water only sprays a few inches, but that's all that's needed.
• A misting system. That's the tall copper riser that you see in the center of the photo. It's a secondary system to the main watering system, and it adds not only moisture to the ground, it adds humidity to the garden, at least for a few inches.
Both systems are on battery-powered timers. I adjust the frequency, and duration, depending on the season. In the heat of the summer, they come on daily, as the year goes on, I decrease the frequency. In December and January, I turn of the automatic watering system entirely. Annual flowers and bulbs that are growing in the winter I water by hand, with a plastic watering pot. I never use a hose. Well, to wash my car, but that's it.
