Arbor Day, a holiday meant to encourage the planting of trees, is officially on Friday, April 25, in Ohio, but CFAES’s Secrest Arboretum will get a head start. The arboretum will hold an Arbor Day tree-planting ceremony at 3 p.m. at the April 22 Wooster Scarlet, Gray and Green Fair. The fair and ceremony are free, and everyone’s welcome. Also at the fair, the arboretum will hold hourly drawings for people to win free trees.
