Hamburg keeps a fairy-tale castle beside the old mill on the Wallkill, which is a strange and wonderful thing for a borough under a square mile to own. Beautiful Creations Landscaping LLC takes the same delight in small, well-made scenes: a lawn mowed in even passes, string-trimmed close around posts and foundations, overseeded thin where the shade wins. Spring arrives here damp and sudden, and by the third week of May everything green is racing. Autumn does the opposite — slow, gold, a long unloading of leaves that has to be gathered before the ground hardens. The pleasure of the job is standing at the curb afterward and seeing a plain yard turned into something composed.
