Water wisdom

Unthirsty plants helped this gardener save irrigation dollars

Style and practicality determined the design of this water-conserving garden in Clovis, California. For owner Claudia Kus, the distinctively Southwestern house style suggested a less thirsty garden to match. But the real issues ― a costly water supply, serious soil problems, and the hot, dry summers of the San Joaquin Valley ― were the clinchers. As in many areas of the West, water is precious ― a limited commodity. Kus needed to manage carefully the available water.

When she began to landscape her 3-acre property in the 1990s, she opted for good-looking plants that don't need a lot of water once established. In the front yard, she planted drought-tolerant shrubs and flowering perennials. Throughout the property, Kus planted trees to create cooling shade ― Australian melaleucas, chitalpa, cork oak, desert willow, hackberry, and shoestring acacia among them. Near a fountain in the back garden, she planted acacia, chitalpa, and redbud. Grapevines ramble over an arbor around the back patio.

Beautiful blooms start with good soil

Before the landscaping began, a cementlike hardpan (an impervious layer of compacted soil) underlay much of the property. To make matters worse, a natural creek that ran through the property in winter was blocked so that it no longer drained. Instead of trying to break through the hardpan, Kus brought in 80 tons of topsoil, which she amended with homemade compost. In the backyard, she sculpted this new soil into curving mounds. Gravel paths between the mounds cover perforated pipes that carry away the excess water to a partially manmade pond in front of the house. (Pipes are buried 2 feet deep in trenches.)
