However you say it, Yes to Arbor Day means pitching in for a greener future.
It takes a lot of Yeses to plant 500 million trees. That’s why when you commit to celebrating Arbor Day, you’re doing more than helping put trees in the ground. You’re saying Yes to a healthier world. So grab your gardening gloves and join an event in your area, plant a tree in your yard, or hit the donate button—however you say it, your Yes makes a difference.
National Arbor Day is always celebrated on the last Friday in April, but many states observe Arbor Day on different dates based on the best tree planting times for their area. Find out when your state or
