I live in San Antonio, Texas. We get about 30in of rainfall on an avg. There is a spot on my property that is facing the southeast and is guarded from the north by the house itself. So it does get scorched by the summer sun. I was wondering if I can grow a small tropical food forest in there. I need some reference materials to research what species of plants I can grow there and how they might perform. I prefer plants including trees that can serve multiple functions. Any idea on what earthworks might be helpful in creating even a better environment for these plants? Thanks in advance for your help.
