East Somerville on a June evening is music from open windows, kids on the grass at Foss Park, and the smell of somebody's dinner drifting over a fence that is holding up a rose bush. Maya Landscape works these blocks in that warm hour before dark, mowing the narrow side lawns, trimming out the corners, laying fresh mulch so the beds hold their moisture through the hot weeks ahead. Space is tight here and every square foot counts, so the edges get cut sharp and the clippings get taken away instead of left on the sidewalk. Spring means opening the yards up; fall means clearing them out. In between, it is steady mowing and a lot of attention to small things.
