Tropical Fruit Discussion / Re: Jackfruit grafting question
« on: November 25, 2021, 09:52:04 PM »
Yes, I have done this successfully.

Do you think it really works?

Shane's graft is just like a regular cleft graft. The top of the rootstock is removed, a vertical cut is made down the rootstock, and the wedge shaped scion is placed in the vertical cut of the rootstock with cambium of both aligned.  Since the sizes do not match, the scion is offset to align the cambium on only one side.

Shane, the question is when do you make that cut, at the time that you do the graft, or after you are sure the graft is successful?
Thanks

When I graft jak, I keep my expectations of success low and occasionally I am surprised with a decent take rate.

I grafted two Luc's with male budwood earlier this year.  All 5 of my flowering Luc's trees are females that do not produce fruit without pollen sourced from a male tree. The male tree was over 15 ft tall so I clipped scions from lower secondary branches that curve upward. So far these two grafts appear to be relatively vigorous and growing upright. These upward growing branches tend to be fairly thick, maybe a 1/2 inch between the first and second node. I grafted them on 4ft trees in 7gal pots.



I have a mangosteen that lost its central leader to cold/wind damage. Two leader branches replaced it. 

This is all easier with younger trees in pots under shade and protected from wind. I tried to graft male scions on a field tree in full sun and in a windy location and it did not go well.

I think this behavior is common to most garcinias. I have seen small grafted achachairu and madruno at a PR nursery that grew horizontally. I have seen this with my personal Luc's garcinia grafts with scions mailed from Mexico.

This is common. I have seen multiple grafted mangosteen in Puerto Rico and the trees do not grow upright and are very compact. I have a grafted madruno that has normal upright growth. I grafted at 3ft  on the central leader with a cleft graft. I have heard theories the source of the scion may also be the cause, that scions should be taken from upright branches

Tropical Fruit Discussion / Re: New(ish) Rollinia
« on: October 28, 2021, 11:25:39 AM »
The rollinia tree has been in the ground for over 8 years. It is roughly 18ft tall and 16 ft wide. It has blown over multiple times and has damage from large roots and branches that have broken in wind events.  I looked at the tree this morning and found a single pollinated fruit, 3/4 of an inch in diameter.  There are also flowers that will be opening in the coming days. The foliage is a healthy green.  Winter rollinias are typically disappointing so I will not hand pollinate. The smaller geffner near it has around 20 insect pollinated fruit of varied size.

Interesting questions, Mr. Brandon!  I don't have any suggestions, yet.

Age and size?

Tropical Fruit Discussion / Re: Rapoza mango nutrient deficiency?

That has 1.7% zinc, which is good. There are a lot of factors so until the tree sends out some new growth, you can't know if your efforts have had any effect.  You can flip a coin and either take a wait and see approach or you can give it another spray. It probably won't matter which in the long run.

The curling to one side and small new leaves is typical of zinc deficiency.

I did not hand pollinate my big rollinia tree this year and got zero fruit. This year, my atemoya trees nearby set an above normal amount of fruit via insect pollination. Last year, I got around 10 fruit with light hand pollinating.

This article from 1988, by Gerhard Gottsberger, has a chart that shows that atemoyas are pollinated by the same insects as rollinias.

Are rollinia are pollinated by different insects than atemoyas(article is wrong), does the proximity of the atemoya trees cause the rollinia to be ignored, was I just unlucky, or is something else to blame?

There is plenty of rotting fruit in my yard to attract pollinators. As with almost everything else in life, if I want something done right, I have to do it myself.  If I want more annona fruit than I can eat, I need to hand pollinate.

Maybe when they reach a mature size. Even then, addition of nitrogen at flowering has shown in studies to increase fruitset but too much causes a decrease in quality. I tend to use less fert than my trees need and high rainfall washes out my soil so not an issue for me.
Helena 8-2-12.  I thought we were to shy away from any nitrogen ferts for mangos?

Brandon,

Thank you.  That new Promate Premium 8-2-12 does look good, with 0.31 Boron.

So, to summarize, your highly productive Orange Sherbet is nearest a large Peach Cobbler mango tree, within a collection of about 40 mango varieties.
The soil test, done by Spectrum Analytics, shows Boron at 1.3 m3-ppm (that lab recommends 1.7-2.6 m3-ppm), and Zinc at 18 (they recommend 4-11).

Different labs use different tests, different calibration soils, and different written measurements--- hard to compare.

Peach cobbler to the south (branches touching),  fruit punch to the east, glenn to the west (40 ft away), a row to the east, super julie, triple sec, m4. Not sure how helpful that is in your search for a pollinator but it says having a melting pot of varieties may benefit picky producers.

My tree is around 6ft tall and 8ft wide growing in the shade of a large peach cobbler mango. It produced 25+ fruits this year. I am using Helena 8-2-12.

My soil analysis is here:

Last time I ordered fertilizer, I was told the mix you recommended is no longer available and they switched me to this, which has more boron:

Female flowers will often appear to form fruits and may hang for multiple months before aborting.  In my experience, a proper fruit will size up quickly,  getting to around 2 inches by month 2. Good luck and keep us updated!

I harvested a six pack of Luc's today. These are small to medium sized fruits that dropped. I weighed them before and after. There is approximately 47% edible flesh by weight on this batch. Two of my trees produce fruit with one or two seeds per fruit and I have another tree that usually has 3 seeds per fruit. The last picture shows Luc's in various size, small to extra large, all from the same tree. The green fruits that are soft and drop are more sour than a yellow/orange fruit but still enjoyable and less sour that many other garcinias such as lemon drop and imbe.

Those look tasty! Congrats!  Hopefully it will flower again in four to six months and produce more fruit.

Where can I buy a G chickeneggulis tree? You know I have garcinia fever  ;)

Awesome job Jay! Looks just like the madruno at Jardines Eneida. Even grown outdoors in Florida,  some garcinia can take a long time to fruit. I was told by Sadhu it can take 12 years for madruno. I have a couple achachairu that will soon turn 11 without flowering.

I ate my first Crown 1 fruit. The taste was similar to a concord grape. It was not overly sweet. The size was good, bigger than the reds I had on hand but not as big as some of the whopper reds and grimals I have harvested. The skin was thicker than a red, similar to a grimal. The skin did not have any objectionable flavors and seemed edible. In the taste test of both of the pictured fruits, I liked the flavor of the red better.

Yes, that is a successful pollination. No guaranties but it looks good and will likely mature.

My PIN Crown 1 in a pot is flowering. My guess is that it is 9 years old.

peach cobbler and juicy peach both have soft flesh.

I have been applying black kow to my lychee trees since the start of the year and so far it is not going well. I applied 50lbs to each tree in January and again in April. The trees are a general yellow, which I believe indicates nitrogen deficiency. The grass is greener around the trees where the manure was spread so there is definitely some nitrogen available. I used Helenas 8-2-12 after picking most of my fruit and will switch back to black kow in the fall.

« on: June 14, 2021, 08:08:49 PM »
I picked my first O-15 yesterday, slightly soft with some color break. This is the first crop on a small tree. I am not sure what the "regular" season is but the other fruit on the tree look like they will be ready soon too.

23
That stuff is very low in nutrients. Compared to an 8-3-9, you have to use 180 pounds of compost for an equivalent amount of potassium in 1 pound of chemical fertilizer.  On a mature tree, you have to use 540 pounds. If you want to use bagged composted manure, use black kow which is 10 times stronger. The higher phosphate of a balanced fertilizer can cause iron deficiency.

24
Another thing to note is that my Luc's are a bit different from Clint's. Based on Raul's sales posts of his different findings and my first hand experience with a handful of flowering trees, I think there is enough variability that future propagation may benefit from seedling selections.  Of the three flowering seedlings I have in the ground, one has a clear productivity advantage. In the fall, I will have fruit from four different trees to see if there is a significant quality difference.

Mike T, thanks for posting your top selections. I have been keeping my eyes and ears open for signs of the elusive Russell's sweet here. I have not seen any available, be it seed or scion.

25
Mangosteens are better. But even if I had unlimited access to mangosteen, I would still eat both Luc's and achachairu. The flavors are different enough to keep it interesting.
