Lemon Grove sits on its own run of mesas and canyons east of San Diego — near enough the water for soft mornings, far enough inland that autumn blows hot and dry. Higuera's Tree Service works the hillside lots where eucalyptus and pepper trees hang out over the slope and the October winds test every one of them. Trimming cuts down the sail a heavy canopy makes in that air; pruning takes the long ends off limbs that have reached beyond what they can carry. Removal is the call for a tree cracked at a union or leaning across a neighbor's roof, and it comes apart in a way the canyon can accept. When the wind wins anyway, storm damage cleanup clears the yard, and the block gets its shade and its quiet back.
