Celebrate Earth Month by thanking the park’s trees for all that they do. As an accredited, Level II Arboretum Madison Square Park has over 300 trees and a rich diversity of species to enjoy. 

Mailboxes with writing materials will be located throughout the park for parkgoers to show their love for any tree in the park by writing a handwritten letter, composing a poem, or creating a drawing. Mailboxes will feature the park’s arboretum map which you can also download here. 

Place your completed letter in one of the dropboxes located throughout the park, or post your letter on Instagram and tag @madsquareparknyc
