MANGO'S

 I've been experimenting with exotic tropical fruit for a few years, I'm always pushing the zone requirement of fruit that the experts say won't grow in tampa bay because it is to cool here. I believe that if you maintain control of the critical growing factors, you should be able to grow anything in this sub-tropical zone ( 9A to 9B  ). Some of the plants that is marginal is mangos, location is the prime issue with growing them. Below 40 F mangos start to go into shock and a little below that they just die. What I am trying, is planting them close to a window on the south side of the house. I expect that the heat escaping from the window should be enough to protect it from the cold.

Follow-up:
                 February 2015, the temperature in Tampa Bay dropped down into the 30's (F). My mango's had already flowered and set fruit, had the normal fruit drop. But the tree's retained a large number of fruit.
