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

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

“Those who plant live oak trees will enjoy shade and splendor for years and years to come,” said John Rosenow, founder and chief executive of the Arbor Day Foundation. “These trees will also add to the proud heritage of Washington’s 82 Tree City USA communities. For the last 36 years, Tree City USA has supported effective urban forest management across Washington, and planting these trees will enhance the state’s tree-planting tradition.”

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. 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 10 free live oak trees, send a $10 membership contribution to Ten Live Oaks, Arbor Day Foundation, 100 Arbor Ave., Nebraska City, N.E. 68410, by September 30, 2013, or join online at arborday.org/september.
