The Tropical Fruit Forum

My fruiting tree was purchased from montoso gardens in PR in 2013.  It wa s 2ft tall in a 3gal pot. I potted it up to a 7gal and planted it in the ground in 2014. It did not do well in the spot I planted it because it was too windy. After years, it became acclimated and  started growing at a better pace. It fruited for the first time last year, 6 fruit. Right now, there are over 100 flowers on the tree, most of which I hope should mature into edible fruit.

Last year I planted some small tress in a wind sheltered area and they are growing fast and always seem to have new leaves. I was gifted a selecto seedling that was two trees from the same seed. When I planted them, one was 3ft and the other was just over a foot. As of now, the former runt is only a few inches shorter, growing over 3ft in a year. In 2020, I planted some that were in 20gal pots. One is now 9ft and the other over 10 but they have not flowered yet. I have seen much smaller trees with fruit and your 8ft trees are big enough to flower now if they are willing.

I am seeing lots of male flowers and panicles that do not set a single fruit.  It has been very humid in my area with no rain so I have anthracnose and powdery mildew.  I expect my harvest to be low but better than last year's disaster.

Taralay just started flowering, O15 good set with anthracnose, buttercream a bit late but seems to be setting, val carrie just flowering, cushman crowded but appears to be setting at top, harvest moon crowded setting on top, sweet tart flowered late seems to be setting, Lemon Zest, ok set with powdery mildew, dot ok set with anthracnose, edward low set, pickering not flowering due to shade, angie flowered late, PPK flowered late, rapoza heavy set but severe anthracnose, venus heavy set severe anthracnose, peach cobbler ok set, orange sherbert good set, triple sec good set moderate anthracnose, m4 flowered late, cotton candy good set moderate anthracnose, super julie good set, phoenex poor set, juicy peach good set, pineapple pleasure poor set, pina colada poor set, glenn good set severe powdery mildew, NDM didn't bother to look.


Fruit punch gets the gold star

It looks like zinc deficiency.

Is there any seed at all? Is there still a husk with rot inside? I think it looks like an insect larvae attacked the seed embryo, and the rot is contamination from the larvae waste. There is a pest known as the mango seed weevil. They lay eggs on the surface of the fruits. The eggs hatch and the larvae consume the seed. The mango seed weevil is known to be in most mango growing areas, Hawaii and in the Caribbean, but not in Florida or California.  Maybe the weevils are already here or maybe these are being damaged by something similar.

My female garcinia trees will hold some unfertilized fruitlets for months. Sometimes they hold long enough to ripen, small and seedless.

I would go for an air layered one just to be safe.

Our 3 year old air layered maphuut bought from a "ngan kaset" fair produced its first fruit this year without other maphuut nearby. According to the seller it's the sweet and "good" type, but can't confirm that because the fruit fell before ripening

I lucked out. I only have two flowering trees so far and got one of each. Both are 6+ft tall and probably 9-10 years old.   My trees seem to mirror what others have also stated, the male is "vigorous" and the female looks less full and less healthy.  The male flowers frequently but the female has only flowered once and only on one branch.

Here is a pic

Dont take my word. Google Garcinia dulcis

The top results that specify flowering characteristics state the following:

It produces male and female flowers on separate plants, and sometimes bisexual flowers as well.

Garcinia dulcis is a dioecious species; however, trees with bisexual flowers and monoecious trees have also been reported.

There are both female and male flowers that grow on different plants; moreover,
bisexual flowers have also been reported

There is also the infamous Ruseel sweet, believed to be dulcis, which is dioecious

 It looks like the damage at the base of the trunk was infected and eventually circled the entire trunk. There was no living wood connecting the roots to the canopy.

Your soil analysis results are showing a few problems.  There is very little organic matter. As others stated, you need lots of organic matter. Add wood chip mulch to cover the root zone and mulch to a meter beyond the canopy 10 to 15 cm thick. The high ph needs to be reduced by adding elemental sulfur granules.  Apply with a broacast spreader used for lawn fertilizer.  Apply around 2kg per 25 square meters. Boron, zinc, and manganese are all very low. Use a quality fertilizer with a good blend of micronutrients. This will take many years to correct. I also think shade and wind protection would be helpful.

People have chempedek in Florida and mine has been fine during 4c/40F mornings.  I have had jakfruit trees die after weeklong rains.  The leaf droop of your tree looks like what happened to my trees. Sometimes the tree recovers after dropping the leaves.

Promoting genetic diversity would be a reason. Sugarapple is fairly well stabilized so it may allow same flower pollination.  There are other possibilities. We still do not kniw if this fruit will reach maturity.

Original poster has another post on wanting to buy a "South Florida" persimmon.  Maybe some wires got crossed.

Raul did sell scions of specific Luc's he found a while back, which he named "Jumbo", "Sweetie", "Sharpie". I have these grafted but not for sale.
