San Diego sits at the far southwest corner of the continental United States, and on a winter king-tide morning in La Jolla you can feel the edge of the map: the sea surges high against the Cove, sea lions bark from the rocks, and spray rises over the bluffs like breath on a cold window. Back from the water, the grass of the park above the Cove looks impossibly green against all that blue. Southwest Greens of San Diego has that corner of the country written into its title, and greens are its business: lawn care for the green ground that makes a yard feel whole. In a place where the light is so clear and the ocean so close, a soft, even green carries extra weight; it is the color that softens all that rock and water. When the tide drops back by early afternoon and the tide pools open up, people wander off the grass toward the rocks, and the shoreline seems to exhale.
