National Arbor Day
Posted on April 21 2026
National Arbor Day in the United States is officially observed on the last Friday in April. This means the date changes annually, falling on April 24 in 2026. Many states also observe different dates based on their best local tree-planting climate.
Check your state's specific tree-planting date via the Arbor Day Foundation's state list.
The 2026 National Arbor Day theme is focused on sustainability, urban canopy growth, and environmental stewardship.
Arbor Day is unique as the oldest environmental holiday in the U.S. dedicated specifically to planting and appreciating trees, rather than just protecting existing ones.
Founded in 1872 by J. Sterling Morton, it focused on proactive conservation and community improvement. The word arbor was chosen as it means tree in latin, and meant to be inclusive of all types of trees.
The origin of the holiday is linked with early sustainability ideas and geared towards planting new trees for future generations. It began in Nebraska in 1872 to address the lack of trees for fuel, windbreaks, and building materials, with over one million trees planted in the first, inaugural celebration.
This holiday is credited with significantly increasing the tree population, combating climate change by encouraging the planting of trees to store carbon and improve air quality.
Events for Arbor Day include tree planting ceremonies, educational workshops, and free tree distributions in many cities.
Ways to Celebrate:
-Plant a tree: Select a native tree species suitable for your local area.
-Participate in local events: Check with local parks, agricultural extensions, or forestry commissions for tree giveaways.
-Education: Learn about the benefits of trees, such as clean air and energy conservation.
Trees and woody plants are emerging as a key sustainable source for fashion fibers. Eucalyptus and beech are used to create the most sustainable textiles by the company Lenzing, as the brands Tencel Lyocell and Tencel Modal. Wood pulp is processed into soft, biodegradable fibers in a closed-loop manufacturing process that recovers and reuses 99% of the chemicals.
