Spruce up your landscape by joining the Arbor Day Foundation in August.

Everyone who joins the non-profit foundation with a $10 donation will receive 10 free Colorado blue spruce trees through the foundation’s Trees for America campaign.

The trees will be shipped postpaid between Oct. 15 and Dec. 10, depending on the right time for planting in each member’s area. The six- to 12-inch trees are guaranteed to grow or they will be replaced free of charge.

“Colorado blue spruce trees provide homeowners with numerous benefits,” said Matt Harris, chief executive of the Arbor Day Foundation. “They can be used as an energy-saving windbreak, for privacy, as ornamental trees, and even as living Christmas trees out in the yard. They truly provide year-round beauty for any landscape.”

New members of the Arbor Day Foundation will also receive “The Tree Book,” which includes information about tree planting and care, and a subscription to Arbor Day, the foundation’s bimonthly publication.

To receive the free Colorado blue spruce trees, send a $10 membership contribution to: Ten Free Blue Spruces, Arbor Day Foundation, 100 Arbor Ave., Nebraska City, NE 68410, by Aug. 31, 2015, or join online at arborday.org/august.
