Everyone from Rhode Island who joins the Arbor Day Foundation in September will receive 10 free trees as part of the foundation’s Trees for America program.

Through Trees for America, everyone is encouraged to plant trees that will benefit the environment and improve the quality of life. With one million members, the Arbor Day Foundation is the nation’s largest nonprofit organization dedicated to planting trees.

Everyone joining this month will receive an eastern redbud, white pine, sugar maple, white flowering dogwood, pin oak, red maple, river birch, silver maple, northern red oak and Colorado blue spruce.

The trees will be shipped postpaid at the right time for planting between Oct. 15 and Dec. 10. The 6- to 12-inch trees are guaranteed to grow or they will be replaced free of charge. Easy-to-follow planting instructions are enclosed with each shipment of trees.

New members of the Arbor Day Foundation will also receive “The Tree Book,” which includes information about tree planting and care.

To receive the 10 free trees, send a $10 membership contribution to Ten Trees, Arbor Day Foundation, 100 Arbor Ave., Nebraska City, NE 68410, by Sept. 30, 2014, or join online at arborday.org/september.
