The blocks here were built for shade — big pin oaks leaning over brick two-flats, alleys running quiet behind every street. Forasteros Lawn Care works those narrow yards in University, where a mower has to know its corners and the trimmer does the rest. Summer arrives heavy and green in this part of St. Louis County and the grass answers by growing all week; the answer back is a level cut and a straight edge along the walk. Clippings get cleared off the pavers before the truck pulls away, because half of a finished lawn is what you don't leave behind. Come fall the same oaks give it all back, and the crew is there with the leaves.
