Arbor Day

trees · environment · celebration · nature

Plant trees worldwide. On Arbor Day, people in many countries come together to plant trees. They dig holes, place seedlings in the ground, and water them so new forests can grow.

Spring timing varies. Most countries celebrate Arbor Day in spring when the weather is warm and trees grow best, but the exact date changes depending on where you live and when it's the right time to plant there.

A global holiday. Arbor Day is celebrated in over 150 countries around the world, from the United States to South Africa to Japan, making it one of the most widely observed environmental holidays.

Trees do so much. Trees clean our air, give homes to animals, hold soil in place so it doesn't wash away, and even give us fruit, wood, and shade to keep cool on hot days.

Everyone can join. You don't need special training to plant a tree on Arbor Day. Schools, families, and groups of friends all work together to make their neighborhoods greener.
