The most limiting factor when growing apples in the tropics is excessive rainfall during blossoming, which keeps pollinators from flying and knocks the petals off; it looks like that won't be a problem for you; there is enough of a change between seasons however that you won't be getting two crops a year as is common around the equator. Florida Prince peach will also be no problem.

Thanks for the info, everybody! I'm going to try and get on a expat forum and see if anybody there has any more info on varieties of fruits. I'll post what I find here in case anybody else is thinking about going south.

I always love posts like this because they make me think about the climate, etc. in other places.

price, I'm not sure that you'd want to grow apples and stone fruit, simply because you would have so many other more exotic things to try. While you might not be able to grow true tropicals like mangoes and coconuts, there are many many things to choose from in the "subtropical" group.

In a similar humid subtropical climate in Japan, the following seemed to grow out of cracks in the pavement:
- citrus, many types
- persimmon
- fig
- pomegranate
- kiwi
- ume
- loquat
- avocado
- temperate fruits (apple, pear, cherry, plum, peach, etc..)

Feijoa is native to parts of nearby Paraguay, but I think it is at higher elevations.

Here's the most extensive list of what can be grown almost anywhere in the country of Uruguay. Some fruits/vegetables do better the farther north you go since the winters are warmer in the north.

Visited Buenos Aires not far away from MV many years ago. My recollection is that it had a climate not unlike Paris, France. Not subtropical. Think I'd investigate European plums in a climate like that.

You can grow darn near anything. I think Mangoes are a no.
