Ten free trees will be given to each person who joins The National Arbor Day Foundation during September. The free trees are part of the nonprofit Foundation's Trees for America campaign. The ten trees are the American redbud, white pine, sugar maple, white flowering dogwood, pin oak, red maple, birch, silver maple, red oak, and Colorado blue spruce. "These trees were selected to provide benefits every season of the year: lovely spring flowers, cool summer shade, spectacular autumn colors, and winter berries and nesting sites for songbirds," John Rosenow, the Foundation's president, said. The trees will be shipped postpaid at the right time for planting between Oct. 15 and Dec. 10 with enclosed planting instructions. The six- to twelve-inch trees are guaranteed to grow or they will be replaced free of charge. Members also receive a subscription to the Foundation's bimonthly publication, Arbor Day, and "The Tree Book," with information about tree planting and care. To receive the free trees, send a $10 membership contribution to Ten Trees, National Arbor Day Foundation, 100 Arbor Ave., Nebraska City, NE 68410, by Sept. 30. Or join online at arborday.org.
