Grew up in Austin, college in Dallas, after that I lived near Canyon Lake( 45min. north of S.A. up 281) for many years, and have now moved north-- to an undisclosed location of course. I'm an avid grower of all kinds of plants, and while Texas is a really tough place to grow, it's not impossible--- I've grown tons of plants right in your area. I'm by no means an expert but pretty knowledgeable with Texas.
Got questions? I can try to help. Fire away Swisha.
