In the old town the lanes are narrow and the privet stands tall, and every yard behind it is its own small room. Deborah L. Wilson Garden Services LLC tends Nantucket lawns through the growing season — mowing, trimming, edging along brick walks and cobble curbs — and clears snow from those same paths in winter. Spring shows up late here and then all at once, the ground softening under a week of soft rain. Work in town is close work: no room for a wide pass, plenty of room for care. Come January the reward is a shoveled path from gate to door, sanded and sure underfoot.
