Tropical Fruit Discussion / Re: Jack Bean for Nematodes
« on: November 26, 2022, 10:08:23 PM »

OK please keeps updated on that investigation.

There are also some plant species that trap nematodes in their roots.

I can report after this season that the Jack Bean I am growing does form galls on the roots from nematodes. So, I am assuming that its primary effect is from the break down of its plant chemicals.

Interesting that you mention the trapping. I just read an article claiming that radish can be used to reduce nematode levels even though it is susceptible. Apparently, radishes are typically harvested so quickly (28 days) that most nematodes do not have a chance to reproduce (typical life cycle is 3-6 weeks). Upon harvest, many nematodes are removed with the radishes since it is a root crop. It got me thinking that this could be a really fast way to rid a spot of nematodes. Just grow several fast crops of radish, solarize the harvest in bags, and then compost. This could probably be done with any number of crops as long as they were pulled up by the roots in three weeks time or so.
I hardly ever pull out jack beans because I'm seeking them as nitrogen fixers but am wondering if what you are seeing might be the nodulation rather than galls?

A well grown healthy Dwarf Nam Wah will make 10 or more hands.
Here is a comparison set of photos which can help identify Nam Wah vs Blue Java. The difference is clear enough but there are many out there mixing these up. Some tissue culture plantlets can be off-type and mislabeling does happen.

This youtube channel has many recipes for liqueurs made with fruits.
I have made wine and vinegar with many fruits. It isn't so hard and most turn out ok, some very good.
The recipe for dragonfruit liqueur uses the peels.
Pineapple wine you use the peels, so you can get extra products out of fruit this way beyond the pulp.

I made a bunch of posts with these top features but Ive decided to just go topless with them.  My friend Thy sent some videos of vietnamese techniques and convinced me its not necessary to have tops.  So the rest of the posts won't have any top feature going forward.  Much easier, cheaper overall Im happy with that.

The indented part of these posts is there so that the top piece can slip on. I used threaded hot dipped galvanized 1/2 inch bolt to attach my top but I like the idea of the indent. My 10 concrete dragonfruit posts survived Hurricane Ian 150 mph winds without leaning and most branches hung on. I really doubt they would have held on with no top piece.

If it is a male very unlikely to ever make a fruit. Sometimes rarely they can make a fruit so this is an ornamental and wouldnt be carrying fruit.

This is a super weather page that links to everything weather related for hurricanes. We are expected to get some strong effects the expected landfall keeps shifting but for now looks to be somewhere just south of Tampa bay.

They have a very fine surface feeder root system which needs improved soil, mulch.

Be careful about eating this. It will need very thorough cooking at minimum and still may not be a real edible type.
They are known to cause throat itchiness,some%20time%20and%20is%20irritating.


Im thinking about approaching vegan restaurants as the most realistic option

but how could I get some from supermarkets? (because that would be the best) I dont think they'll just hand me over the thrown out avocadoes, or what can do I to make that happen?  Get the attention of the manager somehow and talk to him, that sounds to much of a stretch.

Obviously they sell sometimes cheaper ones on discount every once in a while but its rare and it would still take years to accumulate the amount I want in that pace

@cassovary, how did you get a 100 for free?
Go to the wholesale vendors where large users buy their produce. Usually they will be buying a whole box of fruit but it will cost about half or less of the retail price.

You can chop them back but they also can get very large if uncontrolled. You may not want this size tree close to the house because of potential hurricane damage.

Also, they get frost damage and you are fairly far north. Does anyone know of a fruiting specimen near Orlando?

How many functional green leaves are on these banana plants?

Akee, Carambola, Banana, Dragon Fruit.

It looks very healthy well grown seedling. They are very fast growing. It would have been better to break up the soil more around the planting hole when you planted it. I think the base of the plant is swelling fast which is pushing upwards. You can mound around the base they are not like hardwood trees and can be hilled up like corn and will even form adventitious roots. I sometimes plant them deeper than the soil level when in a pot. If it is a good hybrid variety the fruit load can easily topple or break off the plant, they are hollow soft fleshed stems. So, it's important to not let them start leaning. If the lean persists I'd suggest using two strong branches with forks to prop it and form a tripod shape since the leaning gets progressively worse as fruit swells up. Use some wide nylon strapping to attach sticks to trunk. Even then, the whole top can break off because they can carry over 50 kg fruit.

Tropical Fruit Discussion / Re: Growing aa commercially
« on: September 08, 2022, 08:38:55 AM »

Hiby chance do you know if your friend grows dwarf aa? Im trying to find out if the dwarf (BRS Para)is a GMO.
Which would mean it cannot get organic certification in the US.
This paper is describing ordinary selective breeding of that variety,no genetic modification. Mainly they were looking for a shorter early bearing and dryland irrigation adapted selection.

Heat free " Habanero" type Capsicum chinense varieties can be very productive. Anybody growing these ?
There was a large red one like a tropical capsicum. Called Choco maybe ??
This one is commercially grown across the Caribbean islands and central america. I have found it to be very good bears right through rains and droughts.

I don't think you can beat Orinoco banana or dwarf plantain for a staple crop, except they do take up a lot of room.

Usually the rain water collector surface (roof) builds up some dissolvable minerals.

any good ideas for when to pick a melon?

looking at my watermelon now
Cantaloupe types begin to smell musky and may change to a more yellow hue, the stem pulls away from the fruit cleanly.
Watermelon is usually ready when the tendril directly opposite the fruit stem is completely dry.

Worms, while they are good for the garden, if the get in pots, it can be a nightmare. They end up turning the bottom of the soil to basically mush. Not good for plants. I understand that it should be fine in a greenhouse, but if the pots are on the ground the worms will go into them. Here the majority that I find are actually invasive and should be killed. They do more harm than good.

I find "wild" worms even getting into plants raised up on wire racks well above the ground.
They may be coming in as juveniles in the potting mix or climbed up.

I have a large vermiculture system holding 5 cubic yards(~4 cubic meters) and some worms migrate out of that system and get into pots. However, most of my potted plants and trees are only temporary in pots for propagation and are transplanted to ground by year 2. I do notice the worms break down potting soil and this wouldn't be a good practice for trees to remain in pots. I expect they do add fertility when they are active in the potting soil.

I put in mango tree thinking 15ft would be ok since they dont grow that fast here but they are already getting tight. 

20ft is probably better for florida.

I planted some mango @ 10 feet. They are not too tight yet and approaching year 5.
But if year 10 comes and I find they are tight I can eliminate every other one, at that point, to have 20 ft spacing.
They are averaging 40 pounds/tree each of fruit which is 40 x $3.50 USD = $140 USD/year/tree.
The trees cost $15 each at wholesale, so selling for two years easily recoups the cost of those trees which may be eliminated.
Selling crop from those trees another 8 years pays for the establishment and irrigation costs for the whole planting.

So, to me, planting close is not a problem so long as you can be pragmatic and willing to sacrifice excess trees.
After all, we usually thin vegetable seedlings, thinning out trees can be considered no differently.

So based off of a quick read of the article, it seems like this one was made using traditional methods instead of gmo. Looks like China is gonna be keen to not let this one spread out of the country so they can monopolize it. Even so, it would take years until it lands into the US especially with import restrictions (since this is lychee)
Considering Chinas laxity about copy and patent I expect the opposite, that it will be widely copied if any good.

In ground established trees during a flood would be very different from in a container especially as they get older with well established root system. There may be no comparison.

Seeds growing well for a few weeks then declining is often because they are originally growing off seed energy which runs out after a few weeks. From that point on it is up to the soil, light, temperature and moisture you are giving them.

Tropical Fruit Discussion / Re: Best commercial papayas out there?
« on: August 25, 2022, 08:15:22 AM »
This one has been the best for me, but the Red Maradol has also been good. If you are growing commercial be absolutely sure to plant the professional level hybrid seeds. I believe they are specially grown so that the seeds are "Feminized". The advantage of that comes because when you plant them you never get useless male plants, plus some hybrid vigor and known fruit characteristics of size, flavor, and flesh color. As I understand it, the growers of these seeds force a female plant to make pollen which fertilizes a female flower and results in seeds produces no males. By doing this, you can reliably produce seedlings which will all make fruit when transplanted. Commercially you need to be sure there is no chance of standing water around the papaya, full sun and high fertility. Try to avoid leaning trees they bear heavy loads and can easily be lodged over or break off in wind. Pick fruit at first color stripe for shipping.

This shows a fine example of what can be achieved:

The main problem of growing fruits on a commercial scale in most African countries is getting quality propagation material. I have been collecting since 2003, and most need to be carried into Uganda by hand. So hybrid seeds will - at least in the beginning - be a one-time off, after which we need to propagate, select and try to stabilize a lineage, which we can use. Results will obviously not be optimal, but compared to the current situation - a big step up.
Unless you learn to feminize the seeds you will waste half of the acreage growing male trees. Wasting half of the planting can't be commercialized. That is why no commercial farmer would plant open pollinated papaya seeds.
