In DeVeaux the maples were planted long before anyone now living, and by June they throw so much shade the lawns beneath them grow slow and soft. Diamond Landscape & Design LLC works with that light rather than against it — mowing and trimming on a schedule the grass can hold, beds shaped and mulched, edges cut so the curves read clearly from the sidewalk. Design here is mostly restraint: a border that follows the line of the house, a shrub given room to be itself. Then the year turns and the same properties need plowing, walks opened, salt on the north-facing steps that never see sun. Niagara Falls rewards patience, and a yard is where it shows.
