The August sun rides high and hard over Houston at noon, and the only true comfort in a yard is the deep shade pooled beneath the big oaks. That shade is a gift and a puzzle at once, because grass thins under heavy canopy and the ground around an old trunk can turn patchy and bare. Helms Landscape Design does landscape design and lawn care in Houston, and reading where the light falls from morning to evening is where a plan begins. A design that works with the shade instead of fighting it gives every corner a purpose, from the bright strip by the curb to the cool green room under the branches. In a city that spends half its summer seeking shelter from the sun, a yard shaped around that shade feels like relief.
