Arbor Day


Arbor Day trees have the power to restore us in uncertain times

Since 1872, Arbor Day has been recognized as a time to plant, care for, and appreciate trees. Even from home, we can all take practical steps to care for trees and green spaces and to work for a future that is greener, healthier, and more beautiful. Here are some suggestions of things you can do to protect and celebrate trees:

Get to know your trees

Ask the Arboretum’s Plant Clinic for help to identify the trees in your yard or neighborhood. Sign up for an in person or online Basic Tree ID course.

Use the Arboretum’s plant advice pages to research and choose a new tree that is the right size and species for your yard.

Use the Tree Finder by May Theilgaard Watts, founder of the Arboretum’s education program, to learn tree ID basics.

Care for trees and green space

Consult the plant advice pages for information on how to care for your trees.

Ask the Plant Clinic about tree care practices or problems, or to seek other plant and gardening advice.

Watch Plant Clinic videos about tree care.

Register for an online course to learn about trees, nature, gardening, or ecological restoration.
