yeah, that is what I'm saying, I don't think this is specific to a variety because of the first photo.

In the first photo one fruit is developed, with others on the same stem with the small undeveloped fruit.  My 'developed' fruit looks just like that, but have never seen any on my tree go 'all nut'  :)

I am thinking there must be some method to this, natural or chemical?

Tropical Fruit Discussion / Getting Cashew tree to 'nut' not fruit...
« on: April 18, 2018, 03:34:17 AM »
Saw a post for sale about a Cashew tree vareity being sold, but it appears it is not a vareity, only has some special technique to not fruit, but to only form nuts.  How do they do this?  Or is this a special variety?  I have seem Red fruit and yellow fruit, I also have the yellow fruit kind, but mine always sets fruit 100%

By not 'fruiting' the nuts are so much larger!

hopefully pictures explain better ---

Here is another one with a poisonous lookalike, I guess not common enough to do diet capsules yet! 

ผักหวานป่า - Jungle Sweet Leaf, Pak Waan Paa - Melientha sauvis PIERRE (Opiliaceae)

https://www.jircas.affrc.go.jp/project/value_addition/Vegetables/070.html

This grows much larger, and is stumped to produce shoots.  Some people are successfully airlayering up to 24" branches.

I can not comment on taste, I am not growing this one yet.

sure looks like oyster
there is an fb group about mushroom id, bunch of trolls, but some very intelligent people, they would know of any poisonous lookalikes of oyster mushrooms

funny you say that, that is exactly the point I am moving the traps to, a sloping roof between two trees.

Squirrels have a habit of using a sloping ramp to ascend/descend, preferring it to jumping. You can use that against them to draw them in to a trap. A strong smelling oil like toasted sesame is said to be a powerful attractant.

This could be called an Armadillo-nator, and is an amzing invention which uses the animal's natural scent as bait . I am under heavy pressure from these pests and catch several/month even one or two a week using this trap. Before getting one my farm was torn up nightly and I lost sleep hunting in the dark. It requires no bait just put in a shady location and check daily. Worth the money.

I believe is มะกอกส้มตำ is more commonly sold as มะกอกฝรั่ง, at least if you are shopping the trees and not the fruit.  Because Magok Somtum is grown for the fruits used in Somtum, but Magok Pa, or just Magok, is grown for the leaves, otherwise to be clear, you would say มะกอกกินใบ -- Magok for eating leaves
If that is correct, and there isn't another species of Magok I don't know about, that would make Magok Somtum this species:
https://en.wikipedia.org/wiki/Spondias_dulcis
So you should definitely look into getting a Magok Pa tree then, since the leaves are recognized as more delicious than Magok Farang.


What is the difference between the มะกอกป่า and มะกอกส้มตำ. I have one in my front yard but it hasn't produced any fruit yet though the leaves are nice to eat. They do grow fast and I have already had to stump it after only 2 years. The branch which I cut off and threw on the ground also started to shoot very quickly. I might eventually grow these shoots instead of the full tree to try to contain the height. They are quite a handsome tree but they do get big.

Here are a few studies:

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4564651/


https://www.ncbi.nlm.nih.gov/pubmed/17313033

https://www.ncbi.nlm.nih.gov/pubmed/9143215

The first one was already linked above, and the second two are just abstracts... sadly the second one abstract states clearly they are just guessing the link :)    I saw in the similar links they did a 'real' study on rats and found nothing at all.  Perhaps they should move onto monkeys or pigs...  Since reading that Thai university article I am now even skeptical that these guys who did research in Taiwan had the genuine variety, since the Thai university even recognizes a similar looking tree with the same leaves, but only slight difference in leaf size and inflorescence as the one containing papaverine.

hey just to mention if you like Pakwaan, I think you will like Magok Pa also, Spondias pinnata (L. f.) Kurz , มะกอกป่า

Tender leaves are citrusy, but no 'leafy green' aftertaste like tender cashew leaves.

It grows much like Neem, which means really really slow start, sometimes just all out death and hibernation, but then once it kicks in should grow very fast!  I left a 'dead' tree in the ground for nearly 2 months, just yesterday saw that it is growing wild now and also my Neem tree is taking off as well after near death.

I have two squirrels been impossible to catch!  good luck.  I've been setting out two spring door traps with papayas, bananas, watermelon, anything bright colors.  Putting them in high places along walls...

Problem is the squirrels never ever leave the trees, but I did find they travel on a neighbors roof, so I may put some traps up on the neighbors roof.

I'd wait on the dwarf namwa, it is hard to tell if they will do well, sometimes you think you got a good sucker but find out the root ball of the sucker was underneath the main corm more.. so when you cut it off you have barely any corm and barely any roots.  The one behind the one in the pic with the dwarf namwa, that is perfect!  plant a bit deeper to keep it straight and tall.  I usually have no problems removing suckers with a shovel.

Tropical Fruit Discussion / Re: pink namdocmai mango??
« on: April 15, 2018, 09:05:03 PM »
I don't think the attractiveness of the mango comes from ripening chemicals, at the commercial farms each mango is bagged individually and picked off the tree before ripe.  I could not handle more than 30 seconds of that video... they, the translator, and some random old lady on the side of the road would not be my source of mango information.  :)

the black marks on the mangoes I believe are caused by sap, or from fungus, or from the fungus growing on pierced areas of flesh from insects.  All 3 problems solved by bagging.

no it is near death, aloe vera also turns white when near death but they can and usually do recover with a little bit of care.

yes their is also now Namdogmai purple.. 'new' breed from Taiwan, very large, good purple color.  Heard good things, have some grafted trees, set me back around 300 or 400 I think.

I like the video on that page.. cool little setup, looks like that would give great success with lime cuttings.  Make some humidity domes and planters with old plastic  bottles and use coco coir dust as the medium

Hi Dave, I am not that worried yet, some of my research went to fb posts and chatboards, only to find that many people reported immediate effects from eating fresh "Paakwan" which are headaches, nausiness, vomiting, which if you didn't feel, would mean you should be ok.  Which will be better explained below I think.  Also it is ผักหวาน, sweet 'leaf/vegetable' in Thai not ผักวาน, which might be translated as 'yesterday's vegetable'  :)

So from this page from Mahidol University

http://www.pharmacy.mahidol.ac.th/th/knowledge/article/145/%E0%B8%9C%E0%B8%B1%E0%B8%81%E0%B8%AB%E0%B8%A7%E0%B8%B2%E0%B8%99-%E0%B8%81%E0%B8%B4%E0%B8%99%E0%B9%84%E0%B8%94%E0%B9%89%E0%B8%97%E0%B8%B8%E0%B8%81%E0%B8%8A%E0%B8%99%E0%B8%B4%E0%B8%94%E0%B8%88%E0%B8%A3%E0%B8%B4%E0%B8%87%E0%B8%AB%E0%B8%A3%E0%B8%B7%E0%B8%AD/
 
outlines 4 edible species of Sweet Leaf, and 1 toxic variety of sweet leaf. 

This chart shows the difference between between ผักหวาน (Sweet Leaf) and ผักหวานเมา (Sweet Leaf "mao' drunk)  I would need to do more research to understand what they are saying, I don't really understand the terms about sex of the flowers and shape of inflorescense.  The bottom two rows I do understand, showing measurements of the leaves, and how the non-toxic form has wider leaves.  The footnote says explicitly that Sweet Leaf "Mao" can cause death with high consumption.



So perhaps this is all just a misunderstanding of varieties?  I think Dave you better consider where you got your tree from and verify you have the correct variety.

I wonder if they will follow up on that study.. here it says  "describe papaverine as a smooth muscle relaxant and vasodilator with recommended intake of 300 mg a day in doses of 150 mg every 12 hours. Those consuming 600 grams of leaves would achieve an intake of 3480 mg weekly"

So if I'm reading that right.. 600 grams contains 3480 mg of papaverine? so 1 gram contains 5.8 mg of papaverine.
So daily should not eat more than 25 grams of this leaf.  (stay in safe side of 12 hour dosage of 150mg)

Need to break out the scale and eyeball that..   Here only the tender shoots are eaten, I wonder if the study used all leaves, and if papaverine content increases with the age of the leaves. 

One thing I find weird is that it is eaten so commonly here, but never heard anything about the dangers of this leaf here.  I will do more research in Thai language about this, seems interesting.

Is absolutely delicious!  I will be planting more.  I took 6 cuttings, all took and rooted easily under shadecloth.

highly recommend.

Tropical Fruit Discussion / Re: Red Dacca banana tree ?
« on: April 12, 2018, 10:10:43 PM »
I was told once that cuban reds average about 2 years to fruit, I guess we will both find out!  I have some in full sun, and another one in a lot of shade, the one in full sun looks healthier has nice big sucker coming off the side, but the shade one isn't doing bad either, however has produded many suckers that are like 'duds' they don't do anything except peek out.  The one in the shade is also growing taller and throwing out very long leaves.  I'll take a picture later.. however they may be different kinds of reds, since I bought several kinds which were named differently.  (but all in all likely the same or maybe only 2 different kinds)

I have a large one that hasn't flowered yet. It could be that it's under too much shade. Might be worth planting some of its suckers in a variety of positions to see which is the most suitable.

« on: April 12, 2018, 01:08:05 AM »
yes, in Hawaii the only red banana ever heard of was 'Cuban Red'
Since being in Thailand I have acquired what were described as nearly 5 different types of seedless red bananas, these also have red leaf stems and red trunks.  Some do appear to being quite large and thick like Cuban Red, some others appear to have more attributes of 'finger bananas.'  Slender trunks.

There is also the 'Indo Red' which is a seeded wild banana that also has red leaves, very attractive!

My reds are doing much better than the green varieties now so far, the corms seems to handle more moisture better, more suited to the equatorial tropics.  Which was my theory and why I planted so many reds.

If you are in Texas you may have the opposite experience, your soil may have too much drainage.

thanks, I think that matches, especially the part about spiny fruit.

Is it good to eat?

not my photos, in my Thai group feed...  some of the fruits on the ground look larger, is this good to eat?  I think the guy is giving away seeds, waiting for a response.
