The celebration of trees is scheduled from 10am to 12pm and is free to the public. Free trees will be given away at the event. Tree climbing for children will be the highlight of the morning. Children will put on a harness and helmet and be guided by Iowa Arborist as they climb a tree. Demonstrations and other activities are planned for the morning. There will be a special appearance by Smokey the Bear. Join us for a fun and educational day at the Arboretum.
