Yes Welcome !!
- I see zone 8A, so maybe you are not as hot as much of Texas. I know its a struggle to grow them in the heat, but if you can grow tomatoes, you should be fine. I have a dahlia friend growing in Florida - he plants very early (compared to most of us), says they do well until July/ August where they tend to go dormant, then start blooming again as it cools down in the fall.
