By mid-June the roses at Stanley Park are showing off and the carillon carries across the lawns on a still evening, and half of Westfield seems to be outdoors quietly judging grass. Grimaldi Landscaping And Services L.L.C. spends that stretch mowing, trimming and laying mulch so a home lawn can hold its own; come winter the same trucks push snow off the same driveways. It is a full calendar in one pair of hands — green kept even in July, pavement kept bare in February. The payoff is a property that never looks caught off guard, whatever the sky is doing. Tidy ground gets noticed in this city, and the work is meant to be noticed.
