The Tropical Fruit Forum

Here's the thread from last year when I reported my Savannah Cherry (e. calycina) fruiting solo:  https://tropicalfruitforum.com/index.php?topic=51078.0.   K-Rimes suggested it might be a COTRG + Calycina hybrid.  I don't know enough about them to tell.  Last year my COTRG wasn't yet flowering, the only Eugenias I had flowering were uniflora, pitangatuba, and this calycina.

The seeds from these fruit all sprouted, though I threw most of them away as this is a common variety. 

It is fruiting again right now with many fruitlets and some mature fruits already, and while this year I have been cross-pollinating all the eugenia flowers that are blooming at the same time this is still the only mature calycina, the rest are COTRG, uniflora, or others

My solo calycina set fruit.  The seeds seemed normal and I have a couple of them growing new plants.

  I've never heard of guabiju, though, can't speak to that one.

By "flushing out" I assume Epicatt2 is talking about leaching - https://en.wikipedia.org/wiki/Leaching_(chemistry), using water to dissolve accumulated minerals in the container soil and remove them.

Even my in-ground, in-greenhouse rollinia looks a bit yellow in the winter.  It will bounce back to healthy green as it warms up and we get longer days.  Yours might also

Tropicaltoba isn't it likely that your minneola is itself grafted?  Do you know its rootstock?  I know you can have interstocks but I don't know much about their usage.

My in-ground light-green/dark-green variegated minneola produced poor fruit.  It was soft and watery and the tree was overly vigorous.  This one was from Harris Citrus, not sure what the rootstock is the label doesn't seem to say.  I removed it and prepared a replacement non-variegated minneola on flying dragon rootstock.  I am growing the new tree in a container for a few years and then putting it in the ground also, hoping for better results.  I have another containerized variegated minneola that produces decent fruit but I will probably go with the non-variegated type long term. 

Some of the best citrus I've ever tasted were minneola tangelos from the grocery store, but they seem to be very inconsistent.  I really don't want to give up on them yet.  Maybe if it is a poor producer for many years I will.

#1 looks like Mammea americana

I think so too

I don't think you actually need to remove the shell, the idea is to crack it enough to let water in more easily.

The name, most likely. People want to grow chocolate and thats the one with the name.  If the genus was cacao and it was 'cacao cacao' and 'cacao mocambo (bicolor)' I bet the others would be more popular.

I have a cacao for exactly this reason, I didn't even know about the other types until long after I got it.  I have tried a raw cacao pod and its seeds and pulp and I agree neither are very palatable.  I got for the novelty of "Can I grow a chocolate tree?"

Does bicolor require hand pollination?  That is a huge negative I found out about cacao after I got one

Hah, impressive to see a graft right into the trunk of such a large tree.  I hope your graft takes and you get a super strong growing marang out of it

My in-ground sumo makes huge fruit, grapefruit sized, and with prominent neck.  My minneolas have been variable, one was in ground one in container. 

So, Variegated Minneola is interesting because there are supposedly two types, light-green/dark-green and white/dark-green.  Only the white/dark-green type produces red-striped fruit.  More interesting... it seems to be unstable.  My white/dark-green tree has become mostly light-green/dark-green over time and the current fruits are on the light-green/dark-green branches and have no stripes.  The previous fruits were on the white/dark-green side and were striped, like one in that picture.  Others have reported the same thing.

here you can see both variegation types on the same small tree:


and these fruits are *not* striped.  Same tree that produced the striped one I showed earlier.  They are small also, though again the tree itself is quite small.


Sometimes the fruit are necked, sometimes round.

Nice!  I think Variegated Minneola is one of the few variegated trees that is really worth it, the bright red stripes on the fruit look really cool and Minneola can be one of the best tasting citrus

Sugar apples (a. squamosa) have been really finicky for me while cherimoya (a. cherimola) has been easy.  I see that they are graft compatible, does it sound like a reasonable idea to graft seedling sugar apple onto cherimoya rootstock in the hopes of improving its tolerance for wet soil?  I am assuming this is why my sugar apples struggle.
