In April the Beaver Dam River runs loud and cold through Bedford, and the lawns on the slopes above it come back one warm week at a time. Bromley Landscape Design opens the season there — raking winter out of the turf, feeding it, cutting the first true edge of the year into beds that have been asleep since November. Summer settles into a steadier rhythm: mowing on schedule, shrubs kept to their shape, weeds pulled before they can make a decision. There is a real difference between a yard that is merely tidy and a yard that looks composed, and the second one takes planning. Watching a property come into focus over a season is the reason for the early starts.
