Naugatuck's neighborhoods stack up the hillsides above the river, and almost every one of them holds onto a small square of green worth the trouble of keeping. Valley Tree Landscaping Services LLC looks after that green — grass cut on a regular turn, lawns and yards kept up, seasonal cleanups when the ground needs clearing again. It is unglamorous, repeatable work, and the reward is stepping outside on a Saturday morning to a lawn that is simply done. The crew works Naugatuck and the towns close in around it.
