National Arbor Day – April 25, 2025

U.S.

Importance
Celebrate

Broadleaf. Evergreen. Conifer. How well do you really know your trees? Now you have a goal for National Arbor Day.

America’s first Arbor Day took place toward the start of the 1870s — right around the time Congress established Yellowstone National Park. Celebrate nothing less than humanity’s endearment toward nature on April 25, just after Earth Day.

Note: National Arbor Day always falls on the last Friday in April, but many states observe Arbor Day on different dates throughout the year based on their best tree planting times. That varies widely. For example:

Florida — Third Friday in January

Alaska — Third Monday in May

Hawaii — First Friday in November

National Arbor Day Activities

Plant a tree
What better way to celebrate Arbor Day than to plant your very own tree? It's an incredible experience watching a tree grow over the years, and it's an unbelievable feeling knowing that you made it happen.
Don't print this!
Deforestation is a huge problem with many implications, and cutting down on our paper usage is the most immediate way to make a difference. You can go a step further by seeking out brands with sustainable business practices, and by adopting strong composting and recycling habits.
Take a hike
The good kind! Hiking is a great escape from the doldrums of everyday life, and it's an activity that's great for people across a wide age range.

Why We Love National Arbor Day

Natural beauty
With so much of our population living in big cities, it's easy to lose sight of nature's greatness and splendor.
Our planet needs love
Despite some disagreement about global warming, there's no debating that keeping our planet healthy helps to keep us healthy. There's a lot to love about a holiday that helps make our planet a better place.
A global movement
With over 40 nations having their own version of Arbor Day, it's safe to say that this holiday is global. We've got a lot to be thankful for when it comes to trees, so it's only natural that so many cultures have their own day to celebrate.
