 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.

No, that is not a mini jack. That is a male flower in your picture that you ate.

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.

Tropical Fruit Discussion / Re: Mango alongside Durian

Panoramic fruits in Puerto Rico has documented some info on the effects of a direct hit from hurricane Maria. We ate plenty of durian there last year. Puerto Rico has many different microclimates and I believe there are large commercial mango farms but we never bothered with those when we visit. It also is quite a bit easier to travel there.

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.

My guess is phytophthora root rot

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.

Generally, root pruning is more likely necessary in the opposite of your situation, when a tree is in a pot too small for its size. Small trees in large pots usually do not have circling roots. After removing a plant from a pot, I pull at the bottom edge of the root ball in a few places. Small white fibrous roots are not circling roots and should be left alone. If you feel thick roots along the bottom edge, it is probably best to pull the circling root until you find the point that the root changed direction from vertical to horizontal and cut it above the bend. Sometimes the roots circle higher up. In that case, I use and knife or snippers to cut top-to-bottom vertical slits an inch or so deep into the root ball in 4 or 5 spots.  At this point, since your trees have been in the ground for months, it is better to just leave the trees alone.

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.

Have you asked Jim recently? This seed sale post is from Jim.

Not at all.  The probability of 1 seedling being female is probably around 50%. Each added seedling reduces the probability of all seedlings being all male or all female by half.  The probability of 2 seedlings being female is 25%, 3 is 12%, 4 females 6%, 5 plants all female is around 3%.

Yes, I have fruited it here in South Florida.  These trees are dioicous and need male pollen to produce large fruit. A solitary tree can sometimes produce fruit, but they are often small and very few reach maturity.  My 5 flowering trees are almost 10 years old. My 5 flowering trees are female (3% probability). My trees don't produce anything, maybe 5 runts in total, without hand pollination from pollen sourced from a male tree grown by another forum member.  I now have a grafted male planted but that will take years to flower.

I have 3 large 4ft and 5 ft trees in 7gal pots, $150 to $200. These are around 5 years old, maybe they will flower in the year or two.

I have a multiple 3ft and 4 ft trees in 3 gal pots. Some of these were fruited by me. $50 to $75

These are some seedlings that were fruited by me last year.

Tropical Fruit Discussion / Re: when to pick this M4 (with pics)
« on: June 13, 2022, 10:09:42 AM »
My M4s change color, not fully but there is at least a partial color change sometimes areas that are fully yellow. Tropical Acres has a picture and you can see them starting to get color on the tree. M4 are a keitt relative. I have had some early before but typical ripening is later.

E4 or M4? E4 was renamed Sugarloaf and stays green when ripe. M4 is a variety that ripens in late July/August and does change color.

I need to go and check Bill's out. Thanks for scoping it out. I will drive a route that avoids driving by Mike's place. I don't want to see what was done to Mike's trees. I helped him pick fruit on a few occasions.

Back in the day, Mike was a great resource. I must have bought over a hundred trees from him. I am no longer in acquisition mode but I was curious to see what was around. I think I found something for us Southwest Ranchers and surrounding areas. Bills Tropical Fruit Trees. I spent a good deal of time with Mike and he spoke of a neighbor Bill that bought a bunch of trees and Mike always spoke well of Bill. I have not been to Bill's yet but Bill's is two blocks away from where Bender's Grove is located.

Tropical Fruit Discussion / Re: Garcinia Macrophylla or Magnifolia?
« on: June 06, 2022, 11:02:28 PM »
I have a fruiting tree. It is an air layer of a variety called Redlands but it still took around 8 years after planting to fruit. It has flowered for the last 4 years. This year was the first fruiting and I only got 3 small fruit. The tree flowers multiple times a year so I am hoping to get multiple crops. I have been told they are normally diocese but some trees fruit by themselves.

Looks like mammea americana, definitely not g macrophylla or magnifolia

You probably have garcinia aristata

Quite enjoyable, watching videos of your yard and collection. I feel a little less crazy, or at least not alone, as I can't seem to stop adding to ours.

Seems you are on the verge of some serious garcinia fruit production.

Does your g. acuminata have leaves that kind of poke you on the ends? Asking because my tree looks a bit different, and has leaves that remind me of holly in that they are a bit pokey.

I don't think a single cherimoya flower cannot pollinate itself. It will be female for a few hours and stop being female during its transition to being male. By the time it produces pollen, it will no longer accept pollen for fruit production. Self-pollination for cherimoya would mean producing fruit without hand pollination or pollination from flowers of the same tree, not a single flower.  For the rubber band to have an effect, the rubber band would need to be applied after pollination.

I like the taste of LZ better. In my yard, LZ is one of the few trees with a decent crop this year. The anthracnose resistance on this tree is fairly good. Powdery mildew can be a problem but not in my humid rainy area. I am not seeing MBBS yet either. Birds seem to prefer green LZ fruits to most other varieties so it does have higher crop loss from animals.  My mom has a small LZ tree and it also is holding fruit in this terrible year and she did not spray fungicides.  My smaller OS flowered and set fruit but anthracnose wiped out the crop despite weekly alternating copper and azoxystrobin spraying. Only 4 OS fruits remain on my tree.

Those three varieties are all hermaphrodite

Those flowers look male to me. If the tree you have is grafted, it may take additional time for it to produce hermaphrodite flowers or it may have been a male variety so growers can plant a pollinator amongst female trees.  Flowers should have a green ovary in the center of each flower that sticks out and looks like a tiny fruit. What is the variety of your tree?

You can use two solenoid valves connected to the same control wire so both operate simultaneously. Split the area so each valve controls a distinct area so you will know if one fails. This may also allow you to use smaller diameter pipe.
