My personal experience of trying to grow such things in the Keys is to, if possible, try container growing indoors. If you have some seedlings or seeds that you can sacrifice, give them a try in the ground and see what happens. But outdoors is so difficult to control... you can't plant anything that needs cooler temps in the sun because it will kill it quickly (fortunately the shade is bright enough that I have had temperate plants fruit in full shade with no problem), plus the soil is highly alkaline which will kill many such plants, plus then there is the high humidity and unpredictable heavy rain which can cause lots of disease, plus of course hurricanes or tropical storms which can wipe out several years of hard work. Indoors you can control the climate, keep the humidity much lower as it should be, control water and soil conditions, control lighting, and you can also attempt to simulate chill hours more easily. But of course, then you have a tree in your house, and that may not be ideal for all people.
