Texas gardening is its own discipline. The soil shifts from black clay to alkaline limestone within a few miles. Spring lasts six weeks if you're lucky. Summer will kill anything not properly established. The advice you find online—written for the Pacific Northwest, the UK, or some generic USDA zone—doesn't account for any of that. And the generic "Texas native" label doesn't tell you whether a plant belongs in your ecoregion, your soil type, or your specific microclimate.
Most people are stuck not because they lack motivation, but because they lack a framework built specifically for this place — one that accounts for how Texas actually works, and helps them make good decisions about their specific yard.
