Late July in the San Luis Valley belongs to the afternoon build-up: a white thunderhead stacking over the Sangre de Cristos by one o'clock, a smell of wet dust, twenty minutes of rain and then blazing light again. Diego landscaping services works the mornings around it, mowing, trimming and edging while the grass is still cool and the air is thin and clear. Turf on the valley floor grows in a short, bright window, so cleanups, hauling and steady maintenance keep a yard from losing its shape between storms. A crisp edge along a walk reads even better out here, where the sun draws hard shadows and everything looks sharpened. The reward comes at dusk, when the cut lines still show and the whole block smells like grass.
