Down where Galen Street runs toward the Newton line, late May turns everything at once — lilacs done, grass thick, every small front lawn suddenly needing a hand. Mendoza Landscaping takes those yards on a regular rotation, mowing them even, trimming where the mower will never fit, and keeping the edge along the sidewalk drawn straight. Watertown packs a lot of houses into a little ground, so the work is close, careful and repeated, week after week. The reward comes at the end of a run: a street of tidy lawns, all cut the same day, all looking cared for. Lawn care for Watertown and the neighboring towns.
