Millions of trees will be planted Friday as the nation celebrates Arbor Day. Warren Buffett once said “Someone’s sitting in the shade today because someone planted a tree a long time ago.” Marion County Extension Specialist Karen Ackley agrees with that sentiment. She says trees add beauty to our surroundings and add to air quality and our own sense of optimism. If you’re interested in planting a tree, Ackley suggests oak, hickory, and walnut, among others. You can find out more about planting trees and varieties by calling the extension office at 842-2014.
