County of Maui Landscape & Gardening Handbook

The 2011 County of Maui Landscape and Gardening Handbook (PDF) was developed by the Department of Water Supply as a resource for people who want to save water in the yard and learn about what and how to plant in certain areas. It gives a wealth of information on xeriscaping, including xeriscape’s seven basic principals, a list of native plants appropriate for each plant zone, and other useful resources.

County of Maui Community Gardens Project

The Department of Water Supply, along with Maui community groups, participates in an assortment of garden projects. The goal of the projects is to demonstrate the benefits of using native plants and water conservation in the landscape. Please visit the Community Gardens Project (PDF) to see some of the xeriscape and native plant gardens cultivated around Maui.
