This Saturday from 9 a.m. to 2 p.m., at the Maui Nui Botanical Garden, situated at 150 Kanaloa Ave., is the 20th annual Arbor Day event. Presentations on tree maintenance, talks on firewise landscaping, and the distribution of 2,000 native Hawaiian trees are all part of the program. For additional information, go to arbordayexpo.com.

With a rich history spanning over 110 years, Arbor Day is observed throughout Hawai’i in recognition of the benefits it provides for clean air, water, shade, and natural beauty—all of which promote healthy communities and a planet in good health. See what Arbor Day has to offer at Kaulunani.org.
