By the leaves it's root rot which sets in slowly but surely. I have lots of experience with different papayas.
Save it while you can, and the easiest way is airlaying. A cutting won't have energy to survive

Tropical Fruit Buy, Sell & Trade / Re: Looking for banana pups
« on: November 20, 2018, 02:16:19 PM »
Im looking for a Blue Java banana pup, mysore pup and a pitogo pup for my garden. I found some sellers on amazon and eBay but I donít trust them that much.
Thanks.
Regarding the sellers on Ebay. Have anyone here tried purchasing banana pups from them?

What kid of banana are you looking for? I have many varieties.

This year I had like so much fruit that many went to compost. The largest fruit reached 600g and smallest 200 g. one tree produced 5 kg per year.
I overwinter them at 12 C. They don't need water in a humid greenhouse.
If you pot them in ground then transfer them into pot they will die, they don't like to be moved. The root system is very sensitive. Just leave them in a big pot, the bigger the better. Plant them in spring and in winter you will have many fruits. I used to have 12 trees, but because people find the fruit strange, it's not very popular. Very low sugar content, lots of juice with an intense aroma of lemon mixed with pineapple. The juice can slightly burn your lips.
Your plant in the picture suffered form root rot, unfortunately you can't do anything to save it, maybe take a cutting to propagate, but with slim chances.

I agree with Millet. Organic fertilizers are good during the hot season, when you can add microorganisms from compost tea, vermicompost or supplements. Liquid humic acid and humus works well. But here there is another catch, these can also contain bad microorganisms in a low amount not harmful to plants. Still when the plant is stressed or soil is overwatered and cold these will take over. So instance Phytophthora.
If one applies in the winter, the fertilizer won't decompose so fast with the help of beneficial microorganisms. In fact anaerobic bacteria, mold and algae will take over which could in turn lead to root rot, and the soil becomes mushy. for those who don't believe apply organic fertilizer pellets on top of the soil, and put it in greenhouse at 10C or 50F and 90%RH, a white crust of mold will start to grow on top.

There is seedless papaya, which is propagated by tissue culture or cuttings. This is not your case.

Access Denied.

Denied to European users, I think because of data protection.

I didn't look for any research on this. I saw some products labeled as biostimulants made of citrus seed extracts, perhaps grapefruit.

You didn't add everything.
"However, the risk assessment is considered to be tentative and has to be updated as soon as the approval of the renewal of fosetyl and the review of existing uses of potassium phosphonates and disodium phosphonate is finalised"

Anyway fosetyl-al is not forbidden, I just say that they found that it leaves residues especially in the leaves and wood of the plants many years after exposure. I think this substance need more studies.

For me I would use it with caution especially after flowering and while bearing fruit.

OK.
Just an observation, It is pH, not PH nor ph.

nice one ;D

ZnO, are you sure? ZnO is water-insoluble.
It might be ZnSO4.

ZnSO4 burns the plants so smooth, I use it to destroy the algae and mold.

Al-fosetyl indeed is a simple molecule which is absorbed fast by plants. Once inside it transforms into the phosphorous acid. This is the active ingredient which triggers plant release of chemicals to strengthen the plant. Also PO3 ions disturb the cell membrane of some fungi, including Phytophthora.
High values of residue were found in plants even after 2 years after the last spray which made the EU forbid the sale and use of potassium phosphonate as unregulated substance. In US it is used in organic farming. That was also the case in EU before 2013.
Phosphorous acid doesn't disintegrate into nature easily, and has no nutritional value to the plant.  But don't confuse with phosphoric acid which is used to regulate ph and its salts are used as fertilizer.
Here is the review.
https://www.efsa.europa.eu/en/efsajournal/pub/2963

Here is a research on apple
http://orgprints.org/13644/1/059-061.pdf
Just a note, potassium phosphonate yields the same results as Al-fosetyl. The later is a registered fungicide so it is presumed you know the risks and residues levels as with any other fungicide. While potassium phosphonate was sold as a plant strengthener and fertilizer.

Just one note more if you use Aliette or potassium phosphonate, both will turn into phosphonate acid with is effective to kill the patogen.
Bear in mind residues accumulate in plants even after many years. In Europe is was recently regulated it's use.

> iron becomes available to citrus when ph is under 6
Which form of Fe?

I am talking in particular about Ferric EDTA the most used in fertilizers but also about all the iron in general.
Sure there are other forms of Fe which are available to plants up to ph 9. I just say that applying too much iron when you see the sign of yellowing will build up in soil. The main problem is the PH, not that iron that is not present in soil. It's just not available. So most advanced gardeners apply iron to corect the problem. After a while once you correct the ph soil problem the iron becomes  available to the citrus plant in a high quantity which can eventually kill it.
Foliar spray of iron is not effective especially during the hot summer and under high light intensity can burn the plant.
Now if some of you went to the tropics, you can see that the land is red, sandy and lightweigh.. The red color comes from iron. Deficiency in iron over there is hardly seen.
In cold climates the citrus plants have a big problem with alkaline and chlorine water.

Laaz for potted plants though I would imagine applying micro nutrients through out the year would be essential for health and proper fruit production

Micro nutrients in high amounts can lead to toxicity. For instance iron becomes available to citrus when ph is under 6, and with high accumulation in soil can kill the plant.
My greenhouse has also high humidity and as a rule when humidity is high I water less, the plants can take water from the air and water droplets. Of course it depends also on temperature.

How do you test if the seedling is tetraploid?

I think your tree is water stressed. This can come from root problem, such root rot. Now because of summer comes the humidity gets low and the tree is slowly dying.
You can check the roots, and to increase humidity place in under shadow with a plastic cover.

The oil from the crushed seeds is a very good biostimulant to spray your plants.

Here is a papeda citrus - left-(I presume Macroptera used as a root stock in Thailand) and a mature kaffier lime - right. You can see the foliage difference, maybe this can help.

Lebmung your Yuzu tree has so SERIOUS thorns.  It must have been grown from seed.

The plant is grafted. I bought it from a reputable seller, which confirmed me the plant is original and I can expect flowers next year.
Yuzu started to be very popular in Europe, there is one plantation with 8000 plants in Spain, established 3-4 years ago. They claim that Japanese horticulturists visited and tasted the fruit and the quality is the same like in Japan.
And yes the thorns are very big, like 8 cm, a strong nail.

You need to flush the soil with rain/snow water, not chlorinated alkaline water from city network. Also water needs to be slightly warmer, like 35 C to dissolve the salts.

After reading your posts, I always have the desire to buy more citrus trees. Never thought, how fruitful and rewarding citrus in container can be.

This can become an addiction!  :D

It can be salt build up in the potted soil. The plants don't use all the nutrients. This plus the carbonates from water soil will block nutrients uptake.
Try to melt snow and drench the pots untill all the residues come out.
