Okay, thanks for your diagnosis. I think the tree is getting about 4-5 hours of dirext sunlight daily especially in the evening and indirect light for the rest of the day (morning - noon). Right now I put the plant in the shade to avoid direct scorching heat in the midday.I’m certainly not an expert. I look at your photo and my first observation conclusion is the tree has not been getting enough sunlight. Pale green leaves will start to turn yellow eventually and begin falling off. Without a proper amount of sunlight the tree will fail.
The tree is quite weak now. I don’t know if new, and more, sunlight will make the leaves return to a full green color. The tree may just drop these leaves and begin to grow the new buds left behind. This would assume more sunlight to grow. Fertilizing a weak tree suffering from lack of sunlight may be more harm than help.
I’d water the tree as needed and begin a sunlight exposure treatment. That’s what my thoughts are.
I don’t believe Jasmine is classified as an evergreen tree. It only seems evergreen because the leaves remain throughout the year. Indonesia….i can relate to the mid day heat. Vietnam is plenty hot between 11:00 and 3:00. I’m sure you are about the same. Mid day is sort of siesta nap time all over. However, about the tree, I just left the tree out in the sun. It survived very well.Okayy, i didn't know that. The thing is I stumble some site that say this tree maybe not getting enough iron. So what would you do to this I tree?
Oh I didn't know you can defoliage totally evergreen tree. I think you can only do that to deciduous tree.
As the title says, what happen with my water jasmine. I already tried to give it fertilizer (16-16-16 + tiny amount of iron micr via foliar spray.

Wondering what media the plant is potted in and how often it is getting watered as it has chlorosis.
In this case, given the tree has good sunlight, it looks like:
- Compacted soil or likely water logged soil causing root issues See this link for information.
- Nutritional deficiency, media lacking mainly in iron and manganese and magnesium.
- Viruses can cause chlorosis. (However in this case it looks more like a nutritional deficiency.)
Here’s some ideas
1. Overwatering is often the most common cause of chlorosis for Water Jasmine. Be sure to let the tree dry out between waterings and consider unpotting the plant to check the media and roots. If wet use a better draining acidic media and slow the watering schedule. Bark and other organic material added to the mix will help.
2. Use a fertilizer with micronutrients that include the above nutrients. Some examples are Osmocote plus or nutricote, but there are many others on the market. Additionally a chelating agent

I see the main concern now is overwatering. I use common soil + compost + and unburned rice husk (i'm not sure about the ratio). For the watering frequency, the tree is watered every morning. I didn't check the soil consistency yet is it too compacted or not. Tomorrow morning I'll check that, or maybe change the soil altogether with better.Response timing will vary…I sometimes forget about the day and time difference between us. My day is your night….and your day is my night.
Okay, maybe later I will also check the PH of the soil maybe it's to alkaline. Do you ever use elemental sulphur to acidify the soil?Mine has been chlorotic but never quite to that extent. A couple of doses of Miracid or Miracle Gro for acid loving plants took care of the problem.
Yes elemental sulfur is added on occasion. But check the pH first. If decent, check the media.Okay, maybe later I will also check the PH of the soil maybe it's to alkaline. Do you ever use elemental sulphur to acidify the soil?
Well done! Mighty fine development.Here's a little update, so the first photo taken on 24 november, I give it 16-16-16 + Fe 13% on 28 november, and now this is the condition of the plant on 3 december. I think it is a big improvement for the leaves' color although theres still some yellow leaves.View attachment 519643
I'm not really sure since I cannot find the details of the nutrient. But the packaging says MerokeMIKRO® Fe-EDTA (C10H12FeN2NaO8).Looks much better!
Interested. Does this fertilizer also contain other micronutrients?
cheers
