Arbor Day is a formally designated holiday around the world dedicated to honoring, planting and enjoying the benefits of trees. Arbor Day has been recognized in Hawaiʻi for over 110 years, and every November communities across the Hawaiian islands gather to celebrate trees!

November marks the beginning of the rainy season in Hawai‘i, which is the perfect time to plant a tree! Arbor Day in Hawaiʻi officially falls on the first Friday in November, however, tree adoptions and celebrations across the state typically take place on the first Saturday.

If you are a fan of trees, then you won’t want to miss another Arbor Day! Arbor Day is the one day, formally designated across our entire nation, to honor, plant and enjoy trees. Every November, all across Hawaiʻi people celebrate trees with free tree adoptions, tree planting, gardening demonstrations and woodworking and craft exhibits.

– Keren Gundersen, Project Manager, Kauai Invasive Species Committee

Today, advocates of Arbor Day Hawaiʻi are big proponents of native and Polynesian introduced plants with a sprinkling of food trees and soil saving ground covers thrown in. The island giveaways have become a way to celebrate trees and gather with friends, new and old. Each islands’ giveaway has taken on a special character.
