April 15 – 30 | Throughout the Park

Celebrate Arbor Day 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. 

On Tuesdays, staff will be on-site with writing materials and displaying letters in the park for all to view (near the reflecting pool).
