PT is resistant to phytophthora spp so it doesn't have a problem with it. However it is sensitive to drought so not watering it enough may dry out and die.
High humidity, no sun, means no watering, all you need it to adapt watering to environment conditions.
Plants were moved too fast into big containers,, they start to make roots so it takes time, that's why for pots always increase size gradually.
PT as a rootstock is a slow grower, so you need patience.

One of the soil suggestions I received from a nursery in Italy was the following:
- blond peat (about 60%)
- pumice (about 30%)
- some soil to get the right texture  (but he did not mention which soil) (about 10%)

Lenzi uses this mixture, they have 10% garden soil, I wouldn't use it. Instead I would use humus or compost.

Blonde or white peat it's different from the general based black peat used in most of the mixtures that you can find in shops. Black peat retains much more water.

I have an original choc anoc brought from Thailand personally from a reputable nurseryman.
It's good taste, fruits gets yellow, they are not very sweet as NDM. What I like about this mango that it flowers all the time and get a crop in winter.
My tree is in 10 gal container and manged to get 8 fruits.

Do you mean a bioreactor?

That is just a small greenhouse.
I have been using something like that for years where I control the temp and humidity with a sensor and light it with led s. Success rate is very high with proper hormones.
Each plant has different needs though.

That's why I find it weird, it's hot season. The tree is less than 1 year old.

It's a mountain papaya, presumly the mist cold hardy. But to my experiments they are similar in cold hardiness to other specimens from Peru and Ecuador.
It was introduced to that region.

Tropical Fruit Discussion / Lychee flowering
« on: June 26, 2021, 07:09:48 PM »
This is my first year I grow lychee.
I got the plants this spring with flowers on it and now it has several fruits growing. The temperature here got really tropical and humid and will stay like this for 3 months more.
The small tree is 1 ft started to have a new flush now and Ithough is going to put new leaves.  Instead new flowers are popping out.
This is a Wai Chi, supposed to to be of small size.

How many times lychee bloom during a year?

Leave the plant alone it will sort out how many fruits it will set. I read several studies made in China and most ruled out PT as a rootstock for Honey Pomelo.
There is only one way to find out if it's incompatible to FD.
In Southern Thailand they don't use any rootstock for pomelo. They use air-layering. It's vary easy to do it in summer. Then you will see which grows faster and fruits better. I put my bets on air-layered plant.

It's being raining here everyday heavily for the past two weeks. None of my citrus lost even a leaf. They are all doing great soaked in water. As long as the temperature is over 18 C they will do just fine.

Millet is right about the root problems, but I see them start with autumn cold rain, not now.

Distilled water works best

As far as the blooms go, only about 1 to 1.5 percent of them will produce fruit.  Most blooms will eventually die on their own, or will set fruitlets, which will mostly drop (called June drop).  Research by Perdue University shows that one fruit left of a very small tree will not hurt the tree.  As to the leaf fall, I would ask two questions:  (1) how long has the tree been growing in that container without being transplanted, and (2) what is the blend of the growing medium that the tree is planted in?  Among the primary  reasons for leaf fall is a lack of soil air, and or a high level of soil CO2, both caused by soil compaction

Millet, FD takes loamy soil and occasional floods very well, even with the lowest oxygen availability it can survive for a couple of weeks.
It's clear that the aerial parts don't get enough water and lose leaves.
Here I think it's a case of bad graft union. Also pomelo in general shows a lot of incombability with FD/PT

A second cause that I doubt would be a high chloride residue from water, but is this case other trees would suffer as well.

I have a dwarf variaty pm



Do you happen to have V. weberbaueri?

All seeds from shops were collected in 2016, so germination is low.
I do have but not for sale for now.

I have a collection of Vasconcellea, when I will get fruits I will post here.

Thanks for your appreciations.

Kevin: you can read this forum, it has a lot of valuable info, from soil mix, sprays, fertilization, grinding, and so on. Doing all of it, you will have healthy and blooming citrus trees.

Leaf drop it's always a sign that the roots have problems, unless the leaves are really old, which is not your case. Alemow rootstock recovers well if the temperature is high enough. Maybe put some black plastic garbage bags around your pots with a tape, they will get much hotter and help grow roots, then in winter take them off so that the roots can dry from the terracotta pots.

This is my cross between Yuzu x Shiikuwasha, 3 months old seedling.
I am amazed how fast they grow compared to other seedlings, they just flush new growth continously.

maybe seal the graft union back with grafting tape for another 3 weeks. Look like it took, strong sun will probably kill the graft.

I have seeds

I have one plant from the hybrid I made faustrime x amoa 8 which turn out variegated.
Sorry not for sale or share.

It is much bigger than a small tree.

At 8a, do you keep it outside for winter?

The tree is 6ft tall in 14 gal container.
Winter gets down to 10F in my microclimate and 0F outside the city, so no I keep it in cold until freezing and then in basement for a couple of months.
They bloom in May and fruit is ready in November before frost. The summer is very hot so they have time to ripen.

You can try to find seeds, they don't sprout easily especially if the seeds are old. I have a couple of plants left if you are interested but they are rather small.

Use garden sulphur to lower ph long term.  Espoma is the most common brand

In pot culture will not work, use phosphoric acid instead.

I would add straw or leaves around it covering up and outside around the soil rocks or water bottles painted black.
