I became an Arbor Day member and they sent me my "thank you" ten free baby trees. They are year old trees, just little sticks right now, but they'll be fine. I also ordered an older redbud to plant in the space where I tore out an ugly, prickly barberry bush. That tree hasn't arrived yet, which is just as well, as I can't plant it there after all. I neglected to consider the electrical wire directly above the space! I'll plant it on the other side of the front yard.
They came bareroot in some sort of root hydrating gel, and color coded by kind of tree.
Purple = Sargent Crabapple
White = American Redbud
Dark Blue = Washington Hawthorn
Orange = White Flowering Dogwood
The free trees included 2 Sargent crabapples, 3 American redbuds, 2 Washington hawthorns, and 3 white flowering dogwoods. Obviously way too many trees for me, but once they are a bit older I can re-home them. For now, I put one of each kind in large containers, and the rest along one side of a raised bed. Maybe next year, when they are dormant, I will move them. They are too young to be planted in their permanent location right now.
Arbor Day began in 1872, in Nebraska, US, when 1,000,000 trees were planted! Now many countries observe similar holidays. Arbor Day in the US this year will be on April 25. It is traditional to plant a tree on Arbor Day. The National Arbor Day Foundation offers membership, and low cost trees (lower to members), as well as many programs benefiting communities and youth programs.
