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.

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.

Halawa Xeriscape Garden is located in Halawa Valley's Central Park Industrial Area. It re-opened to the public on Wednesday, February 1, 2023, after being closed for an extended period of time due to the pandemic.

Notice: Mulch No Longer Available at Halawa Xeriscape Garden

As of July 2014, the BWS no longer offers free mulch at the Halawa Xeriscape Garden in order to align with statewide efforts to prevent the spread of invasive pests. Mulch piles are potential breeding sites for the Rhinoceros Beetle, an invasive scarab beetle that feeds on coconut palms. For alternative free mulch giveaway sites, check with the City Department of Environmental Services (ENV).
