Pine Street in the South End keeps working well past five, and so does the grass, right up until frost. Five Seasons Property Management handles the lawn side of properties around Burlington: mowing on schedule, string trimming, edging, mulching, hedge and bed tidying, spring startup and the long fall cleanup. Looking after grounds in this city means knowing the growing stretch is compressed, that one rainy week can double the growth, and that October does not wait. Evening light comes low across the warehouse roofs and lands on a lawn that was cut that morning. That is the small daily proof the work is getting done.
