The white/buff skinned mottled/purple fleshed Okinawan sweet potatoes don't sprout very well. I eventually got some going by slips from somone else. The vines, however, are vrey difficult to ever remove once they get going every piece left keeps on growing.

Lots of videos on this. Maybe it is true but I've seen some deceptive claims before so beware some have commercial reasons to exagerrate. You could translate and find out the story, looks like a good mystery which I love seeing solved.

I'd love to see a video showing the details it would help a lot of people. How many thousands of acres citrus do we have mowed or sprayed at great expense? Let me know if you need an online host for the video I could do that.

Carambola is sensitive to iron deficiency.
This one is available in Florida, even at Lowes/Home Depot.

Speaking of dragonfruit skin I followed this recipe for using dragonfruit skin to make a sweet liqueur using rum and it is as advertised. Guests enjoyed it in clear soda with a squeeze of lime if they don't like sweet drinks.

It woud help if you showed the whole tree. Most leaves look good is this just one branch with the veining?
Is it potted, what soil is it growing in, what area? Any deficiencies in other trees, plants, etc? What do the Ixora plants look like in your area?

I cast concrete posts and tops then put 4 cuttings on each. Using the posts gave me plenty of room underneath for pineapples, I've even grown lettuce a few times there. If I had used a trellis there wouldn't be room underneath.

I think it depends how much room you have for bananas and how much light you want coming through. I started with bananas between newly planted fruit trees so unless I remove pups the mat will end up with 3-4-8-10 stalks and expand too wide. When that happens, bunch size and competition for light begins to create limitations, bunch size decreases and plants grow taller and skinnier seeking light. Over time the mat grows vertically and pants are more superficially rooted with thinner taller pseudostems, leading to breaking over and even uprooting with loss of the bunch.

Some of this depends on variety. My main crop is Orinoco tall, it sends out 4 or more pups after every bunch so by the 3rd season if none get removed you could have more than a dozen trying to fruit. I also have plantains and a few dwarf bananas and letting them have multiple stems leads to leaf disease they like more air circulation.

The last concern is because my bananas are interplanted between fruit trees they are beginning to limit light to the trees as I head into the 3rd year. I'll be re-working all my mats down to one stalk on the mat and replanting to start over this year. It might be the last year for the interplant between trees. However, last year I planted bananas in rows between fruit tree rows, so those will become my new mats. As they are already limiting light to the fruit trees I am being more selective in culling pups. My new method is just cutting off pups when they get about 3-4" diameter at ground level, then using a long kitchen knife I core out the growing center of the pseudostem to kill off the corm without actually digging it up. It seems to work. Overall the bananas as intercrops gave me a lot of production over the years as main fruit species grow up. They also created a lot of biomass leaves and stems wich are now enough to mulch around the fruit trees constantly. It has been a win-win and I know things will change. I've only plated half the farm so It looks like I'll have 6-10 more years where I can keep the cycle up doing the same as I plant more land. Eventually bananas will become secondary and probably just for personal use instead of something the land produces every single week, I generally have 30-100 pounds every week and it is still increasing.

Looking back at the original post I no longer leave 3 feet of stem at harvest I cut everything as low as possible to get mulch for the trees. 

I get this too an old timer told me to cut them off since they remain as a disease reservoir so I do that. Your tree looks healthy but best practice seems to be regenerating part of the tree annually by pruning to keep it healthy and control size for picking. Pruning stimulates growth and should be done asap after fruiting to set up the fresh growth ready to flower in spring. When you prune now you will be amazed at how it suddenly will bud out fresh. I did some 2 months ago which have flushed 2 feet of new growth. I cut some tops, some tips and a few branches 1/2 way, but all immediately began to grow fast. Don't be afraid to prune avocado unless it gets close to January.

I was able to find two seedling trees which are consistent with what I have seen as the Gamthi variety. The leaves are very broad and thick, it is rather slow growing. A one year old tree is 3 feet tall. Same fragrance as the regular form. It just happned to be what was available. I don't have any available for sale or trade yet. I sourced them from found seedlings at the Florida Gulf Coast University Food Forest. They may not even know what they have but it is special. They have a website and are probably looking for opportunities to get revenue. A year ago there were numerous seedlings coming up so if you can look up the cooordinator they might offer seeds.

Guillermo ilama seeds available again, this tree consistently yields 40-60 fruits a year, tastes like raspberry cheesecake.

If you read those studies the cases usually involve people with prior health complications, who were fasting, or took the juice in an unusual context.
Turmeric and Cinnamon both contain more oxylate than ripe sweet starfruit, and spinach, beets and chard are very close.
Vegetarians/vegans ingest far more oxylates than meat eaters just because most veg contains it.
Even if oxylate is present in a substance, some of the oxylate can be soluble and some insoluble, for instance the oxylate in turmeric is almost all soluble and available for uptake, levels in cinnamon are only 6% soluble.
Calcium in the diet tends to bind to oxylates making them less soluble, so using high oxylate foods in a low calcium diet means that more soluble oxylate will be present.
In the gut, Oxalobacter formigenes, a common part of the internal microbiome breaks down oxylate, but the presence of that bacteria varies in individuals and may be totally absent  after antibiotic use or during certain disease states.

I read a few publications on oxylate in general and found this one directed at vegans to have some good information.
