Saturday morning on Broad Street smells like bakery and coffee, and the neighborhood is out before the heat is. Caraballo Landscaping LLC works those hours across New Britain — mowing, trimming and edging the compact yards behind the porches, then sweeping every walk clear so the block looks put together by noon. Mulch goes dark around the beds in spring, weeds come out before they get ideas, and autumn brings the long leaf haul. City lots reward attention: an inch of trim along a fence line changes the look of an entire house. That is the part worth doing right.
