I would think South Florida would have some dwarf fruit trees for sale...you guys have a TON of nurseries out there ( I used to live in Miami) many years ago...

Growing your own would require planting with seeds and that would be a very long wait for them to fruit usually so I would suggest buying grafted or air layered trees...

You can also try Ebay (make sure you're getting one from a reputable) vendor...Check out the Nurseries in your area and ask they "if" they are willing to special order you a specific tree? Good luck!!

What type of Dwarf Fruit trees (specifically) are you looking for?

There are several Mango (Dwarf and semi-dwarf) varieties out there for you to choose from...

Lukas Nursery in Oviedo, FL, has on their website that they have dwarf citrus in stock. Grafted on Flying Dragon stock and grows about 5 foot tall, but not much more info than that.

Might have to do a road trip, because I don't know if they ship.

As far as I know, Lukas no longer has Flying Dragon, there was an industry. wide growing failure with it a few years ago. Brightleaf http://www.briteleaf.com/citrus_trees.asp#DwarfCitrusTrees
Is the only reputable citrus vendor that had truly dwarf rootstock, and was able to knowledgeably answer questions about it. I purchased dwarf trees from them, they have been excellently, established rapidly and are fruiting this year.

And of course easy to get dwarf mango cultivars - go to the fairchild yearly mango sale=)
