Preserving & Protecting Sunken Gardens for the Next 101 Years

First dedicated in 1924, Sunken Gardens is now 101 years old. Its last major restoration was nearly 60 years ago. Tree roots and invasive plants have begun to threaten the stone walls’ structure, prompting essential preservation work.

As a results, parts of the Gardens may look different over the coming months. Treatment and removal is scheduled to begin on or around September 24, weather permitting.

Two invasive tree species will be treated using basal bark treatment – a method recommended by the Indiana State Department of Agriculture and State of Indiana Cooperative Invasives Management. This involves applying a solution to the base of the trees that works slowly over many weeks, allowing us to remove them safely while ensuring they are unable to regrow.

The careful process is expected to last well into 2026.

Thank you for your patience and support as we restore and protect this historic space for future generations.
