East of Riverhead the lanes narrow and the privet grows tall, and by the middle of June every hedge on the road is asking for a haircut. Hamptons Tree & Shrub Care works the green season on lawns and plantings around town — mowing, trimming and edging, shrubs and hedges brought back to a clean line, beds mulched so they hold through the dry weeks. Spring opens with a cleanup that clears winter out of the borders; autumn closes with leaves carried away before they mat down over the turf. The work is repetitive in the best sense: the same properties visited again and again until they simply look right. A shaped hedge and a straight edge do more for a house than nearly anything else.
