The youth group at St. Mark’s Episcopal Church in Southborough will be hosting a plant “unsale” to support their summer mission trip to Niagara Falls, NY. The event will be held on Saturday, May 7, 8:30 a.m.-1 p.m. at the Southborough Transfer Station (lower level; no sticker needed) at 147 Cordaville Road. Make a donation, take a potted plant home all while supporting a worth cause.
