Union Avenue keeps its shade the whole summer, oaks and elms arching over the road toward the track, and Congress Park holds its old specimens where the springs come up out of the ground. Trees on that scale need looking after: thinning, deadwood taken out, a reading of what the leaves are saying about the roots. Arborist Advantage Inc works on tree care and pruning, keeps an eye on tree health, and removes what has passed the point of keeping. Bringing a tired maple back to a full green crown by August is a result you can stand under. Saratoga Springs, Wilton, Greenfield, Ballston Spa and Malta are all on the route.
