Arbor Day is The Morton Arboretum's signature holiday. In Illinois, the last Friday of April is Arbor Day, a special day set aside to plant, care for, and honor trees. Arbor Day is celebrated around the world on a variety of dates; find a list here.

Celebrate Arbor Day

Arbor Day in the classroom
We also help teachers, students, scout troops, community groups, and municipalities celebrate Arbor Day in the classroom in April or any time with tree tagging kits for discovering the value of trees, Tree Census lesson plans, and other support.
Arbor Day Poster Contest
In 2014, teachers and students can participate in our Arbor Day Poster contest to help spread the word about the value of trees. LEARN MORE
