What has been your experience with the flowering peach tree in this climate? I live in the Houston area and have 4 flowering peach trees: pink, red, white, and peppermint.
Do you want to know about the tree in the Southwest or in the Houston area?
Actually you're not in the Southwest. Your climate and growing conditions are worlds different than most of the rest of us.
You're in the south or southern/Gulf coastal area. There are a couple of other forums that would probably be of more help to you.
