May in Weldon Spring is a month of edges — bed lines recut, mulch laid dark against the first hard green of the season, shrubs shaped back before the heat arrives to settle in. Zach's Lawn and Landscape LLC likes the overlap where mowing and landscape work meet, the point at which a yard stops reading as a chore list and starts looking composed. The county's clay holds a border well once it has been cut clean, so the shape stays crisp deep into summer. Mowing keeps the lawn honest week to week; the beds and plantings are what give it a frame. Good bones set in May carry a yard through everything Missouri sends afterward.
