Trees, trees, trees…and so much more! It’s the Arbor Day Celebration in Mellon Park and the Fifth Anniversary of Mellon Park Arboretum! On Saturday, April 26, from 11:00 a.m. to 2:00 p.m., please join Friends of Mellon Park and dozens of community organizations on the south side of the park for an outdoor family celebration where all are welcome. We’ll be on the oval, just uphill from the corner of Beechwood and Fifth Avenues. There will be art and nature activities for children, music, food trucks, a Pittsburgh fire truck, and much, much more.
