Push a spade into Houston and you meet gumbo: dark, heavy clay laid down by ancient rivers across the coastal prairie, sticky as molasses after rain and hard as brick in a drought. The Ground Up is a fitting name for lawn care in a city that sits on soil like that, where a good lawn depends on everything happening beneath the blades. Out along Brays Bayou in November, egrets stalk the shallows and the mornings finally carry a chill. As the turf eases its pace, the mowing grows lighter and the focus shifts to keeping the lawn uniform and strong for the short winter ahead. Healthy grass over stubborn clay is a small triumph, and it shows each time a passerby slows to admire a front yard that looks effortless.
