Mountain Avenue keeps its old median and its old trees, and the strip lawns beneath them are cut close and kept plain. Carlson Lawn Care, LLC works blocks like these — mowing on a regular turn, trimming around trunks and hydrants, edging the walks, clearing leaves when the season empties the branches. May is the demanding month in Fort Collins, when growth outruns the schedule and every yard needs cutting a day sooner than planned. Keeping pace with it is the craft: an even height, a straight edge, nothing left scattered on the sidewalk. From Old Town out to the newer streets, the standard doesn't change.
