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

The foundation encourages Americans to plant trees to benefit the environment and improve the quality of life. With nearly 1 million members and supporters, the Arbor Day Foundation is the nation’s largest not-for-profit organization dedicated to planting trees.

Everyone joining this month will receive one of the following tree packages based on their location: 10 Arizona cypress, 10 live oak or 10 mixed trees including 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 September 30, 2016, or join online at arborday.org/september.
