, Welcome to ATP and the Texas Gardening forum. When we lived in San Antonio, I could grow most anything. Soil was good, weather great. Here in Austin, we seem to have too little rain, or too much rain. I would suggest you look on the left side of the home screen here on ATP. There's a section called Goodies. You will find what grows in your planting zone and when to plant it. I would also suggest checking to see who your county horticulture agent is. You can get a lot of good information sent to you from that office.
Are you in the city or are you in the country? Texas has lots of deer that love gardens! You'll have to find a way to fence them out. Fall is a perfect time to start a garden where you are. I have a grandson that loved planting (and eating) carrots and tomatoes here when he was smaller.
San Antonio has a wonderful Botanical Garden. You can see what grows well in the area there also.
