Dahill Road runs its long diagonal through Kensington, and every April the yards on either side of it begin again from nothing. Dahill Landscape Design shapes that beginning — beds cleared and edged, mulch laid down, the lawn cut low and even for the first time since autumn. Shrubs are trimmed into proportion with the house, borders drawn so the planting reads as a plan instead of an accident. A yard laid out well looks effortless later, which is the whole trick of it.
