For mango, look into Pickering.

Macadamia trees grow very large & I don't think they would do good in a container. That's just speculation, however.

Dragonfruit will do well in containers. Try to have a strong trellis for the dragonfruit to climb. Otherwise, it will become a many-headed hydra which makes it hard to harvest the fruit. I have 8 varieties currently.

I have a Kohala longan, Sweetheart lychee & 5 varieties of cherimoya in containers. 5 gallon for the first two (which are still small), 15 gallon for the cherimoyas w/fruit on 1.

I think avocado would do well in a large container.

In containers, I think your ok with:

Mangoes ( Condo Variety )

Sugar Apple, ( I have a A. squamosa fruited from seed only 3 years in container )

Dragon Fruit, ( easy in container )

Miracle Fruit, ( Do very well )

I have no experience in the others, but pepper and passionfruit, should be ok.

I noticed you do not have Banana or Papayas, they can be grown in containers, and are nice ornamentals too.

Although I have a few Mangosteen in container, I do not think they will fruit in a container, they have a lousy root system, basically a long tap root, with very little else. but they can grow years in a pot, they are sooooo slow growing.

I hope it's OK to bump up an old thread like this, as I am quite interested.

Did OP find success with these tropical trees? I have limited yard space and initially ruled out mango, papaya, and cherimoya. But if they fruit reasonably well in large containers, will certainly consider them! How much spread would they require?

Wow, resurrecting an old thread :)

Many of the trees listed above are ultra tropical or tropical, not sub tropical. What's needed to grow mangosteen and cacoa is a whole different level than avocados and dragon fruit.

I grow everything in fabric Root Pouch containers ranging from 15-45 gallon. Every kind of dwarf citrus does well in 15 gallon, as does tropical guava, dragon fruit, passion fruit, fig and a ton of others.

I have my macadamia and avocados in 45 gallons. Macs won't fruit until they reach a certain age, which usually means they're no longer dwarfs. I keep my mac in a 4x4' area which isn't nearly as huge as they'll get. My avocados will be pruned when they get a certain size. Mango also does well in containers. Papaya can be grown in containers, though they can't be pruned and will need some space to grow. There's some dwarf varieties like TR Hovey. Cherimoya can be grown in a container. Just go for it and prune when they get too big :)
