Yes it looks like a micronutrient deficiency. Possibly linked to substrate PH.

There is a tropical vegetable forum here, but it is less active.

Here is the latin name for your plant: https://en.wikipedia.org/wiki/Cnidoscolus_aconitifolius

Tropical Vegetables and Other Edibles / Re: Tree collards in subtropics
« on: September 29, 2022, 12:01:47 PM »
The tree collard I put out front made it through the very long dry spell recently. All the grass died but it didn't even blink.

Idk if it is a named variety but I got the cutting from amazon.

Edit: it is green. I haven't had much luck with the purple leaf.

Looks like a Lacewing.  Lacewing's are beneficial as they eat quite a few of he bad bugs such as aphids, mealy bugs, thrip ect.

Lacewing have much more pronounced heads and wings. This looks like some kind of leafhopper sucking insect to me.

Tropical Fruit Discussion / Re: RFID tree tags
« on: September 23, 2022, 12:16:18 PM »
A QR code tagged to the tree will be sufficient.

I asked my son who is a tech genius about how I could tag trees for agritourism so that visitors could have a self guided experience using a cell phone. He quickly found that RFID tags are available for the purpose. When in proximity the phone powers up the tag giving you a website link to information.

I'm just now exploring the idea so haven't narrowed my sourcing and details etc but often see interest in tree tagging here and at this point it seems like this tech is available.

A qr tag would be subject to the elements and would likely become unusable depending on the conditions. An nfc tag would likely be much more durable.

Sounds like NFC tags. They're pretty neat. You have to hold the phone right next to it so you could probably integrate it into a sign of some sort.

Citrus General Discussion / Re: TDS levels and gray water watering
« on: September 22, 2022, 12:41:55 PM »
TDS is derived from EC (electrical conductivity)
Tds/ec measurement does not tell you what is dissolved, just how much electrically charged particles are in solution. Without testing a sample there's really no way to be sure what is in it.

As I understand it you still have to watch the EC of water you apply, including liquid fertiliser mixes ( and ultimately dry fertiliser that dissolves in water ).
Basically if NaCl salt has an EC, then so does CaCl, MgCl, and also MgSO4 etc etc. all common component of fertilisers.
Yes some are going to be beneficial nutrients and some more harmful, but a very high EC from any compound can be a problem, particularly in pot plants.

650 is not a very high TDS measurement for established plants, but you're correct that we don't have a sense for what compounds are dissolved. Judging by the small difference in measurement between the tap water and soap nut water I would guess that would be ok at least. OP could look at their municipal water quality report to get an idea whats in the ~300 ppm of their tap water.

Aside from getting a sample tested for water quality, OP could dilute the grey water further, but that would probably be negligible (talking about the soap nut water) since the difference in tds isn't all that much.

I would be concerned about the other laundry detergent though.

This is correct, assuming you know the quality of your source water. When it comes to hydroponics its usually recommended to start with RO water as a source to start clean. When you start with a high ec source water, especially if you don't know its specific components, you run the risk of nutrient toxicities, especially when it comes to micros and (to a lesser extent but more in this case) sodium.

The oil won't stop the latex from coming, it just helps it to not stick to the knife and your hands.

Usually people put down newspaper or something to protect their work surface.

That said, assuming you haven't been pouring salt down your drain, I would assume it would be safe since the numbers you mentioned aren't very high to begin with.

If you want to be sure, I'd suggest getting a test done.

Yes the latex will stick to your hands too, pretty hard to get off. Gloves might be the best.

More oil will work to break down the latex to remove it from hands or utensils FYI.

Same reason why you don't use oil with latex condoms.

Jared made juice with the trifoliate orange and reported that his significant other had a bad reaction to it, just fyi.

Tropical Fruit Discussion / Re: Tropical Sources of ALA (Omega-3)

Evening Primrose oil (Oenothera biennis) is a vegetable source of Omega -3 and -6 Fatty Acids.

Useful for those not wanting to source Omegas from fishoils.

OK HTH

Incidentally, fish get their long chain omegas mostly from algae. You can get algal dha supplements now. Algal oils are superior to fish oil since they are usually produced in closed loop systems so they don't have ocean contaminants. It can also be produced on land that isn't usable for growing anything else.

Here is the seed, with a thumb drive for scale. They are relatively plump and not what I would call flimsy. Some of the fruits have no seed or an aborted one though. It does look similar to Parvifolia but the skin is thinner and the sepal is more pronounced, looks like on parvifolia the sepal detaches completely when ripe?

Edit: thought I mentioned it but the seed itself is covered in latex and is very sticky once the pulp is removed, if that helps

Are you sure?  I have a single black sapote seedling tree and it fruits.  Pretty sure there are no others around

According to wikipedia there can be male only trees. That said, I'm not sure if it is possible to sex black sapote seedlings this young.

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?

Inga wood usually super brittle too. Large branch nearly dropped on neighbors head a while back.

We usually fry them in oil then smash them and fry them again. Thinking about making green banana flour tho.

Walnuts are not tropical. Pecans are subtropical with similar nutrition as walnuts.

Juglans neotropica is a species of tropical walnut FYI

Can you show a seed? It is definitely not G.cowa.

I will have to get a picture when its lighter here but the seed is similar in size to purple mangosteen, usually only one seed per fruit if that. The seed is covered in the yellow latex when you remove the fruit skin.

I wouldn't be surprised if you can get $10/seed on other forums though.  If she's doing 2 for $10, then that's not necessarily horrible.

I know not everyone has access, but these have become way more available; Here in FL, if you look around a bit you can buy a 1gal tree at that price or $15, and yes, I've seen that a few times not just isolated instances.  The price of 4 seeds would buy you a decent 3gal tree.


Best luck!

Etsy is expensive because they charge through the nose to sell on their platform. There's no cost to advertise here.

Out of curiosity, what other tropical fruit forums do you visit?

Oscar with fruitlovers.com usually has them in stock

Aloha!

This fruit was sold as Garcinia Cowa but does not match pictures on google. I'm assuming it is garcinia but I could be wrong. Flavor is similar to apricot with small amount of astringency. Fruit size is a bit larger than a quarter.

In warmer areas a lot of citrus stay green when fully ripe.

I see you are in Hawaii.
I have heard of this, also regreening of Citrus fruit.
Always thought it was mainly peel colour.
Does the fruit flavour also revert to less ripe ?

Citrus greening is a disease and not the same. To my understanding, they have to get cold enough to turn from green, but they are still fully ripe.

I tried a green clementine recently, as I remember they are popular in Egypt at green stage. Full sized, just braking colour.
A bit sharp, refreshing. Bit like mild Rangpur Lime.
