Tropical Fruit Discussion / Re: Which fresh mulch for mango tree?
« on: January 11, 2020, 04:19:33 PM »
I have plenty of experience with causarina mulch as a former tree trimmer.   These mulch usually consisted of a lot of shredded pine needles and thin branches, usually mulch piles will kill grass due to lack of sunlight and heat, but causarina mulch effects grass much more, you can see a border 2 feet from the mulch can die back, and grass will come back very slowly where this mulch has been (even if for 48 hours or so)

Perhaps other pine species are much better, but I do believe all types of pines have chemicals which are  herbicides against new trees and grass.  As an evolutionary strategy Pine is not competing with grass, but other trees.

So I would just warning anybody who thinks about using this mulch to tread carefully because there is some special chemical characteristics of causarina pine mulch, perhaps enough to kill a papaya tree.

mango real susceptible to root rot, root disease, and boring beetles at the trunk if soft and wet.  So I would be real light on the tree and 3' from the trunk.  Also boring beetles do love mulch to lay eggs.

Pine mulch is not good for anything usually until is fully composted, there are chemicals in the needles which will kill grass, so trees won't like it.

Most Thai people don't know about Elephant apple.   But in all cases about trees that are in Thailand, nobody is more knowledgeable than the Thai people, so much more information can be gained from Thai language resources. 

Some english resources for example will only cite "medicinal value"
but then you can go to a site like

https://medthai.com/%E0%B8%A1%E0%B8%B0%E0%B8%95%E0%B8%B2%E0%B8%94/

And they will actually tell you what medicine to make, how to make, how to apply, etc..  However dosing information is usually not mentioned.. so not a complete resource.

Interesting fact is that these trees are actually eaten by elephants, so they will occur all along the routes of elephants near jungle, mountain, and especially waterfalls and fresh water.

They are especially hardy, and if you see one sprouted near the tree (a near guarantee) then pinch it out and put it in a container, it is a very attractive potted plant, that is also very hardy like Banyan.


The roots seem to have a very similar medicinal value to willow, however medthai lists number one reason to plant "Matad"  (don't confuse with Mahat) as---

นำมาใช้ประกอบอาหารเพื่อรับประทานมาตั้งแต่โบราณ เช่น การทำเป็นแกงส้มมะตาด แกงคั่วมะตาด หรือนำไปทำอาหารอื่น ๆ หรือใช้ผลสดจิ้มกินกับน้ำพริก[3] กลีบชั้นในที่มีลักษณะอวบอุ้มน้ำ ใช้จิ้มกับเกลือกินได้ ให้รสหวานอมเปรี้ยวเล็กน้อย

Used as food since ancient times, cooked in the "Gaeng Kua Style" (note below), or ripe fruit is eaten with chili paste, or the petals can be eaten with salt for a sweet and sour taste.

"Gaeng Kua" style is when you are making a curry, first you stir fry (Kua = roast) the spices and meats before adding water/coconut milk.

I imagine to roast this harder fruit it would be chopped up finely first like how other curry pastes incorporate minced ginger, lemongrass, chili, etc.

With this amount of information available, don't be afraid to eat some ripe petals next time, but if you want to cook the ancient curry, then you might want to research some more on portions and if you are using green Matad or ripe Matad.

Sadly I only learned this much later after studying the one I had in a pot, and one of the Thai gardeners thought it was a weed in the pot and tossed it when I was away.  I collected my seed from a remote national park and haven't been back since.


Heres a tree I found in North Thailand
Never seen it anywhere in the past
Any help with ID is appreciated

Thanks

« on: January 03, 2020, 03:47:01 PM »
is this a new remarketing campaign on the well established:

ส้มโอสายน้ำผึ้ง  (Honey Pomelo Strain)  ส้มโอขาวน้ำผึ้ง (White Honey Pomelo)

 or is this ส้มโอขาวแตงกวา (White Cucumber Pomelo) different?

Personally Had my mind blown by a white/natural/honey colored Jabong here in Hawaii.  Was a superior large juicing grapefruit I think Jabongs are from the Phillipines.

I planted single quadrangularis vine, set fruit, but I have other passionfruit vines on the property that could have cross pollinated it.

Hi all growers!
i m planning to plant two plants of passiflora quadrangularis, and i have a little hesitation because it is generally described as not self fertile. But what if i plant two of them close to each other? will they pollinate each other? Since this is said to be very common a plant in the tropics, what is your experience?
By the way, if i plant two passiflora ligularis next to each other, will they pollinate each other?
Thank you!

Tropical Vegetables and Other Edibles / Re: Florida grown kratom?
« on: December 16, 2019, 01:23:30 PM »
agreed, not sure what the confusion is in the states... I ordered Kratom plants from Big Island grown in Oahu, and some serious wind and salt burn.  The strain was a 'green' strain, which chew about 5-6 small leaves, red vein chew 1-2 large leaves.  Your really not supposed to feel anything, Kratom makes you not feel, so the effects of sun, sore muscles, etc.. aren't as pronounced when chewing kratom.

The youth like to boil it up, but those same youth also experiment or are hooked on meth.  Old timers and laborers in my province chew only.  If I had gardeners show up to work with a bag of chewing Kratom I wouldn't care, but if any started boiling it up I would fire them and change the locks.

Here in Thailand it is quiet easy to get hold of, but illegal.

You can defiantly feel the effects if you chew multiple leafs, after a while it numbs your mouth.

Here they normally boil it with coca cola and add cough medicine, as it increases the effect.

Kei apple from bark inversion



And possible first peanut butter after 3 years of continual flowering



my pb fruit plant was very slow to acclimate to being planted, coastal lowlands with flooding heavy clay, planted in shade of bananas plenty manure & weeding.  Took about a year for very little fruit.  3 years in the bush has about tripled the size as the potted plant's original size and fruit set is very good.

Perhaps wind, rain, or just shock kept the fruit from setting early on, but now the bush is doing very good.

So don't be discouraged from very little fruit being set, even though bush is full of flowers.

cool, wonder what type of tree that is, the grass jelly I've had before but never thought to grow it!
Seems like a good idea, especially if the brush type can be grown in dry season in between monsoons:

perhaps commercial fruit growers could heat it at low temperatures adding sugar and water or some other chemical process and convert the oxalate to something else?

if your really wanting a big sweet crunchy one, head to Loei, they have the best guava in Thailand, their climate is best for it, being a bit more subtropical like Hawaii.

Tropical Fruit Discussion / Re: Most Outrageously Delicious Canistel Ever
« on: November 19, 2019, 03:22:13 PM »
also interested Oscar, I had a horrible Canistel from Frankies, and now I'm convinced mine I planted from seed will be horrible as well.

On Maui I had great canistel, paired with cheese and crackers was amazing.

That Maui canistel looked like Abiu in shape, so much that my friend gave me an Abiu and I assumed it was the same variety.

best source of knowledge about this would be from the communities who drink 'sour' starfruit juice.  I'm sure they have several generations of common sense knowledge about how much to drink and who should avoid.

Just like in Thailand they recommend people to avoid Durian if you suffer from hypertension or to pair with mangosteen to help offset... but in Western science there is no evidence to support any of this.

had a lot of rain lately?, topsoil waterlogged?

My starfruit dies off every year during monsoon like this

In this one I think is a great study, and I was shocked, until... correct me if I'm wrong the type of juice given to the subjects was not specified.

Shortly after a graph showed that juice from unripe fruits (sour juice) contained 820 mg/100 ml of oxalate, compared to ripe fruit juice around 40 mg avg.. so 950% increase in oxalate in unripe?

Still interesting, but still not entirely clear, but this study definitely has scared me and will be concerned with any food containing oxalate.

btw other two studies were looking at people already experiencing kidney problems, so those are suspect.

Perhaps in summary, people with diabetes should avoid green starfruit, and also the fact that starfruit is picked and sold green is not helping.

Tropical Fruit Discussion / Re: Citrus and Passionfruit insecticide help
« on: November 11, 2019, 11:14:49 PM »
I've never really used insecticides before, but it looks like I need them.

Bugs love my passion fruit vine; I regularly see big holes chewed out of leaves. Bugs like new leaves the best--sometimes, when I can see the plant is going through a growth spurt, it will mainly be a vine extension that grows because I can see most of the new leaves got eaten. I never actually see anything eating it though.

Today, my pumelo tree was crawling with bugs, most of which were the citrus psyllid. The tree already has greening, but with regular fertilizer and root growth hormone application it's starting to come back. But I doubt it can put up with all the bugs on top of greening.

I think insecticide is the best way to deal with the problem. Right now, I'm looking at this one. I don't want one that harms bees, and I'm unsure of the proper time to apply fertilizer. I haven't applied insecticide before; can anyone help? Thanks.


when inspecting the new flushes on the 30 lime trees I planted there are consistent problems with two types of pests.  Both lay eggs or breed on the new flush, and the leaves are going to be very inefficient once mature, prone to fungus, and fruits will be stunted from the inefficient leaves.

When I am there I will spray the new flushes as preventative, and trim any damaged areas off the tree and burn.  Also if I get water I will wash and rinse off by hand, because of thorns just cutting off the areas is much easier.

Also would mix in foliar nutrients with the insecticide, so giving the new leaves a good shot of vitamins and protection for a bit.

Using it once a month like this in this limited targed amount I think is very responsible, I also catch all run off in fish ponds, so who knows... perhaps once the trees are larger can make do with hand washing and targeted pruning.

if you get enough rain, it will grow to make a quick windbreak.  Space tightly 6-8 feet apart in a single line, it is very fast growing and would make a good source of tinder or softer pole handles in 2-3 years.

hey Sunny, I planted a few new kinds 2 years ago, picked up some very healthy air layered ones from the Ag University fair in Surat Thani.  The one in the picture caught my eye for the odd large shape, and also it is seedless. I'll let you know later if it is good.

excited to eat my giant green skin pear shaped seedless white flesh ones.. Taiwanese or Thai I don't care, I have high hopes but pig is only one eating them for now.

no doubts Syzyygium jambos

said this variety thornless, I would not plant it, might be impossible to get rid of later, too many scarred fingers from dealing with the thorned kind.

the leaves look like Syzyygium jambos, which differ from other roseapples in that they are very slender, and will flush a beautiful dark purple.

Very fast growers, I have several in beautiful 30 gallon pots and they look very nice, on the other hand same seeds planted at a friends are over 30 foot tall in <3 years.

Might want to separate now before roots get too tangled if you are planning to keep more than one.

Tropical Fruit Discussion / Re: Adding sulfur via soil plugging
« on: November 06, 2019, 10:42:37 PM »
plugging is very smart, I have my gardener hammer in 2-3 holes with a sledgehammer and a steel pipe to delivery 12-12-12.  About 12" deep.

Since so easy, and another person mentioned spreading it out, just do with steel pipe but instead do 3-4 holes around perimeter of tree.
