Downtown Haverhill is brick — long mill blocks along Washington Street with the river moving behind them — and the green turns up at the edges, in dooryards, side lots and the strips of lawn behind the triple-deckers. Migo Landscaping tends exactly that kind of ground, mowing, trimming, edging and running the seasonal cleanups on city parcels where every square foot is already doing a job. Tight spaces reward a careful hand more than a big machine, and one small yard cut well can lift the look of a whole block. Spring starts here with a rake and ends with the first even cut of the year. It is honest work in a city built on it.
