Monsoon arrives in the Yuma Valley as a tan wall on the horizon, and an hour later the yard is wearing half the desert. Qun landscaping does the after: righting what the wind laid over, raking the gravel smooth again, hauling off broken limbs and the grit that drifts up against every wall. The rest of the year they build, setting desert plantings that can take the sun, laying rock and gravel clean, shaping borders that hold their line in a place where everything wants to spread. Their work suits the light out here, which is merciless about a crooked edge and generous about a straight one. When the next storm comes through, it all stands up better for having been done right.
