The Gladstone Branch pulls out of Bernardsville early and brings everyone home in the blue part of the evening. HELMERS landscaping LLC works the hours in between, so a lawn left ragged at six in the morning is cut, trimmed and cleaned up by the time the train doors open again. Summer here settles into a weekly rhythm — grass up, grass down, a straight line held along the walk and around the mailbox post. The year opens with a cleanup that takes the road sand and broken sticks out of the turf, and ends with the lawn cleared before the ground goes hard. Nothing announced; just a yard that has always been handled.
