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 Hawai’i 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 Hawai’i 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.

AGG Arbor Day 1“Arbor Day gives us the important opportunity to share with the community of [Hawaiʻi] the importance of urban forestry, and a grander scale, the importance of how urban forestry impacts the entire ecosystem of Hawaiʻi.”

  • – 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. Featured below are glimpses into the celebrations across the State.

This year, Arbor Day falls on November 6th in Hawaiʻi. Many of this yearʻs celebrations will be hosted online, and while we eagerly await the day where we can celebrate this holiday in person amongst our community members, there are still many ways to get involved!

Our favorite way to celebrate our urban forests is by planting a tree! Offering seedling adoptions on Arbor Day has been a custom in Hawaiʻi since 1993, and this custom will still be present this year at many sites across the islands thanks to the work of Kaulunani and our partners!

City and County of Honolulu – Liliʻuokalani Botanical Garden Tree Planting
This year to celebrate Arbor Day Hawaiʻi, the City and County of Honolulu Division of Urban Forestry (DUF) are partnering with the School for Examining Essential Questions of Sustainability (SEEQS). These students are developing projects focusing on soil science, erosion, planting design, and native out plantings at Liliʻuokalani Botanical Garden (LBG). Our horticulturist Talia has been advising SEEQS students on their projects and guiding them to plant native groundcover, shrubs, and trees at LBG. We will be planting various species of native trees including koa, alaheʻe, lonomea, hao, keʻahi, and more! We are excited to be working with these bright students to learn, plant trees, and care for such a special place.”
