The first mow of the year in New Bedford usually lands the week Brooklawn Park turns properly green and the ballfields start filling up again. Carvalho Lawncare starts right about then and does not stop until the leaves are gone — mowing, string-trimming the corners no mower can reach, edging walks and drives down to a clean seam. A spring cleanup opens the season by raking out matted thatch; a fall cleanup closes it before the first hard freeze. Grass in this city lives on sea fog and long light, and it will run away from you in June if a week or two slips. Keeping it even, week after week, is the craft.
