The Waterville Public Library plans to celebrate Earth Day this spring by participating in the 13th annual Neighborhood Forest free tree program, the aim of which is to provide free trees to youths every Earth Day.

To get one, parents can fill out an online registration form by Monday, Feb. 28.

The tree, 6 to 12 inches in size, will be delivered to the library during Earth Week, April 22-30, where it can be picked up. Planting instructions and species information will be emailed a few days prior to the trees arriving.

Since 2010, Neighborhood Forest has reached over 100,000 families and planted over 50,000 (mostly urban and residential) trees through the hands of children and parents across North America.

To register, or for more information, visit watervillelibrary.org or neighborhoodforest.org, email [email protected], call 207-872-5433, or stop by the 73 Elm St. library.
