Introduction

PHOTO

Prepare your spades and gather your seeds, because National Arbor Day is just around the corner on April 26! This incredible day of green initiative was first established back in 1872 by J. Sterling Morton in Nebraska, United States. His vision was to set aside a special day for the planting of trees, so he could inspire people to create a greener, healthier planet. From this idea, an incredible 1 million trees were planted on the first Arbor Day itself! Nearly 150 years later, National Arbor Day remains a testament to the power of grassroot environmentalism. So mark your calendars and join us on this day to celebrate the majestic beauty of trees, their life-giving properties, and their essential role in creating a sustainable future for all!

How to Celebrate National Arbor Day

Plant a tree

In the spirit of Arbor Day, get your hands dirty by planting your own tree. Whether it's a sapling or a mature tree, every bit of green helps! Remember to choose a tree that will thrive in your local climate and planting conditions.

TAKE

Take a tree identification walk

Test your knowledge of local flora by taking a walk through your local park or forest preserve with a tree identification guide. This fun activity will help you familiarize yourself with the trees in your area, and show appreciation for their individual characteristics and beauty.

ORGANIZE

Organize a community tree planting

Invite friends, family and neighbors to participate in a community tree planting event. This is a wonderful way to bring people together and create lasting memories. Plus, you'll have a visual reminder of your efforts as these trees grow over time.

TAKE

Take a leisurely stroll through a local botanical garden

What better way to appreciate trees than to visit a place dedicated to preserving and showcasing a variety of plant species? Enjoy the serene environment as you saunter through pathways lined with towering trees and vibrant green foliage.

DONATE

Donate to a tree-planting charity

If planting your own tree isn't feasible, consider making a monetary donation to a reputable, tree-planting charity. Your contribution will help fund the planting of trees around the world, aiding in the fight against climate change and promoting biodiversity.

WHY THIS DAY MATTERS

Why We Love National Arbor Day

We are helping combat climate change

By planting a tree or donating to a tree-planting charity, we directly help combat climate change. This holiday offers an opportunity to be part of the solution in a practical, tangible way. In essence, we are contributing to the growth of the world's "lungs", improving air quality and the overall health of our planet.

Engages us with nature

National Arbor Day reminds us to reconnect with nature in an active and meaningful way. Planting a tree is not just beneficial for the environment but also helps improve our mental wellbeing - it's a peaceful activity that allows us to step away from the hustle and bustle of our daily lives and engage with the nature that surrounds us.

Promotes community involvement

Arbor Day fosters a sense of community. From planning a communal tree-planting event to going on a tree identification walk together, the holiday encourages people to work together for the common good of the environment, thereby strengthening community bonds.
