La Mesa calls itself the Jewel of the Hills, and the name earns its keep on a clear evening when the streets climb toward the ridgelines and the lights of the county come on below. San Diego Landscape Remodeling does landscape remodeling and lawn care here, where yards tilt with the land and a single hillside lot can hold a garden on three levels. Most mornings a gray haze drifts in from the coast and lifts before lunch, leaving a mild, pearly light that plants seem to adore. Down in La Mesa Village the trolley bell rings past the shopfronts, while up on the slopes a remodeled yard can turn a forgotten bank into a place to stand and watch the sky go orange. That change, from tired ground to a landscape that feels new, is what makes this work a pleasure.
