About Halawa Xeriscape Garden

The Halawa Xeriscape Garden displays a series of xeric (dry) plants in a residential-scale setting to demonstrate species capable of providing a visually attractive garden, while using less water than most currently popular plants. It was opened to public in September 1989, after several years of effort by the Board of Water Supply (BWS), as a way to educate Oahu residents on ways to save water in lawns, gardens, and landscaped areas.

In these demonstration gardens, you can familiarize yourself with the kinds of plants and grasses that need less irrigation, as well as the variety of approaches that use water more efficiently in the garden. These approaches include irrigation techniques, cultural practices, and landscaping ideas that will provide for drought-tolerant gardens and landscapes.

Among the water-efficient irrigation systems demonstrated in the Halawa Xeriscape Garden are automatic timers, moisture sensors, rain shutdown devices, and low output irrigation equipment such as spray sprinkler heads, micro-spray sprinkler heads, emitters and dripper lines.

Suggested cultural practices that can save water are also seen at Halawa. These include: mulching, soil alteration, turf mowing practices, thinning of planted areas, weed control, and fertilization.
