What it comes down to is that now more than ever, the world needs more trees. We are answering the call with our ever-growing network of planting partners in keeping pace with the increasing need and focusing on areas where trees will do the most good. Known as the tree planter’s holiday, Arbor Day is a day for people to come together in recognition of the wonders of trees. Communities, schools, businesses, and individuals alike join together to plant commemorative trees, hand out free trees, provide education on tree planting and care, and celebrate all the benefits trees provide. National Arbor Day is always celebrated on the last Friday in April, but many states observe Arbor Day on different dates throughout the year based on best tree planting times in their area. This celebration of trees, however, is not limited to the U.S. Countries around the world celebrate Arbor Day or a similar holiday dedicated to trees.
