Sulphur is very effective and for potted plants the solution can be really long lasting.
There are though some points to consider:
- The effect will depend upon several factors namely the chemistry of your soil (concentration of calcium, carbonates, bicarbonates...) some soil exhibit a strong buffering effect (thus requiring higher amount of sulphur to lower the pH) some are more sensitive.
The right amount should be determined sperimentally therefore you should try starting with small amounts then, if necessary, adding more.

- The effect is "delayed" because the mechanism goes through the oxidation of elementar sulphur to sulphur oxides then eventually to sulphuric acid. Don't expect to add and see the pH lowering! Be patient and wait before adding more and more.

Ideally you should pre-mix thoroughly with sulphur  the soil to be treated then wait some time, check the pH and use it for potting.
The time requested for the sulphur to affect the pH depends on temperature, humidity and level of oxygen.
Making it simple, warmer temperatures, humid (but not damp) soil and good aeration will make the process faster

You're welcome. I really hope you can manage to solve it. Root problems are really bothering and sometimes can be lethal  :(

For me it does NOT look like a nitrogen deficiency. Millet is right, nitrogen is readily absorbed in a wide range of pH and it highly mobile element so i would expect deficiency to show first in older leaves.
Moreover the sucker is of a brilliant dark green and the affected leaves show  yellowing veins not typical of a nutritional deficiency.
I hope for you it's not Phytophthora, did you check tree trunk?

Finally a little mangosteen plant with 4 leaves!



Hope it will grow well

Looking very  fine, keep it warm and wet and don't overwater

I had several of them in my property , they are one of the most invading species i've ever seen, fruit bats eat the fruits and spread seeds everywhere.
They manage to germinate and grow in pure limestone under the scorching equatorial sun.
Their roots are extremely long and can extend horizontally much much wider than canopy, forming a thick net of branched rootlets that can reach any other tree  avidly sucking water and nutrients.
I had several of them removed since they prevented other fruit trees to grow normally.
Some of them had roots longer than 30 meters (100ft).
By the way, any  root portion  exposed to the sun will promptly generate a new tree.
Look at this picture, these trees were born spontaneously from seed and are LESS THAN THREE YEARS OLD.....

It definitely looks like a ROOT problem.
Evidently roots can't absorb water/nutrients and this brings all the symptoms you see on the tree.
Success/failure of any tree is mainly under the ground and this is particularly true for avocado.
I'd try to dig a litle bit in several spots at different distance around the tree trunk to visually inspect the status of the roots.
Ideally you should find a thick net of thousands of healthy white/creamy coloured feeding roots.
If they are not present or they are dark brown/black then you should start to worry A LOT....

Oh my God I'm starting to think that my cuddled ilama seedlings are actually just common SOURSOP :-(
I'm wondering how it could happen.....
I've no pictures now since i'm in currently in Italy but leaves are dfinitely leathery and glossy like a soursop.
So bad :-(

9
Ah Ok, thanks for your reply,  then i can have peace of mind.
I would'nt like to grow a SOURSOP thinking it's an ilama and then finding out after several years that i was wrong  :-\

Sowed the seeds in october 2017, sprouted few weeks ago.



Your seedlings have pale green "smooth" opaque leaves.
Mine have glossy leathery leaves similar to the one of annona muricata.
Something is wrong, what are the "right" leaves of annona diversifolia?

I think absolutely NOT.
Tha said, I'd prefer budwood from a health tree instead

Watering is OK but I start to fear that it's something connected with root water uptake too....hopefully not root rot, nematodes  or similar

Black sapote?
Some people say the taste is very bland, is it true?

14
I've seedilings 6 months growing from Raul's seeds, white fleshed variety i'm plannig to move them to open soil next january.
Thanks Mike

15
That's definitely a great news Mike  :)
You've both white and pink/red fleshed varieties?
what can you say about the taste?

Holy s.....what kind of temperatures/humidity/wind speed  range you had to experience such an awful damage????

Thank you Millet! I'm always here learning drops of wisedom from this forum.
Actually they are mature leaves. Temperature are always in the range 26-32 C (79-90 F) in this period.
What worries me most is that just some branches exhibit these strange leaves. 95% of the tree branches  have happy upright crunchy leaves only a few of them have these wilting ones...

19
No Brian they are not. Look at the last picture and compare them to the normal ones very "fresh" and pointing upwards.
These ones look "sad" and even at the touch it seems they are lacking water....bad sign since the tree is well hydrated...

Citrus General Discussion / Ponderosa lemon strange leaning leaves
« on: July 31, 2018, 04:13:51 AM »
This is one of my ponderosa lemon trees.
It's 4 years old from a small cutting and now planted in "soil" and producing  plenty of juicy lemons all year round.
This variety seems perfectly adapted to the hot tropical climate of the philippines unlike other varieties i've here.





Apart from an evident zinc deficiency (that I'm trying to correct with Zinc sulphate solution spraying) this tree has never given any problem.
Nevertheless, lately i noticed that somethig strange is happening.
Some branches have weird "leaning" leaves with a wilted appearence.
I looked out for worms/borers, parasites but i couldn't spot anything.
In some pictures it's evident the difference between the upright normal leaves and the  sick ones.
Any suggestion?
Thanks in advance!

YES thorns are really scary but they disappear on mature trees and high branches :-)

Would i trigger a hurricane saying KEITT ??

I strongly doubt yours are really Flacourtia Jangomas.
Don't trust any vernacular names (coffee plum, indian plum, governor's plum...) because they can be deceiving.
Mine is locally called SARALI and just after a long research i found out to be actually Flacourtia Jangomas.

I post some pictures .
This is the actual tree, 5 years old from seed (more like a big shrub about 3m tall)





The long, sharp and scary thorns along the base of trunk and main brunches. Thanks god the upper branches and canopy are thornless





Here a detail of leaves and young fruits. At the moment unfortunately no flowers









Here the fruits, most of them are  in nice clusters









Here is a ripe fruit. It's a tiny fruit, about 9-10 grams. Skin turns deep purple, it's thin and edible.
Flesh is deep yellow  firm ad a bit juicy if fully ripe.
Taste is very pleasant, strong, sweet with a hint of sour and tangy. If eaten unripe it can be very astringent
Seeds are flat and don't bother










Very easy to grow, mine is actually on a thin limestone layer among rocks.
All in all i love it :-)

24
Mine is 5 years old now and it looks more like a large shrub than a real tree.
I will post some pictures soon :-)
