Arbor Day Resources

A greener world

Since 1872, Arbor Day has been recognized as a time to plant and appreciate trees. The Arboretum usually celebrates this day with a tree-planting ceremony and similar gatherings on-site. This past year, to ensure social distancing in support of public health, the Arboretum was closed for the month of April. The isolation brought on by this temporary shelter-in-place reinforced more strongly than ever the human need for connection with nature and the value of trees and cherished green spaces. 

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 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.

Teach children to identify and appreciate the trees around them, using the Arboretum’s Learning in Place resources.

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