Like Deb said, there are quite a few Texas gardeners that post on this website. I, too, live in the Texas Hill Country and have gardened here for 17 years. We do have our own special challenges with the rock, cactus, caliche, limestone, and critters (deer and armadillos are the main offenders). My gardens consist mainly of Texas natives because they're tough plants and look natural for the area. Plus the deer 'usually' don't eat them.
Would like to hear more about what you've planted or plan to plant.
