Water-Wise Oasis: A Tucson Desert Garden

Scant rainwater sustains a lush garden in urban Tucson.

The cool season garden is planted within sunken mulched basins. Brad and Rodd harvest a large salad bowl of greens and veggies a day, grown entirely from rain harvested in the soil and from the 1,200 gallon pre-cast concrete tank that harvests water from half of their metal roof.
