Not enough moisture at that age. They are dying of thirst.

How can I save them?

I have since repotted them and left them under the shades. It's about 5 months old btw. Do I need to bring them into a cooler place? Since the sun is basically GLARING everyday with about 34°C daily.

Any advice would really help. Thank you.

Where you are, water them every other day. After a week, put them back in the sun, keep watering them that way. 34C is nothing. These plants thrive in the hottest open spaces of Africa.

I would go what Pagan says ! Now in fact. Here I water everyday in a porous mix all summer and they do excellent until I give them away. Like weeds. )

If u using porous soil, water it everyday. It is a baby adenium it needs more water. Mine i keep indoor under grow lights, i use only 20% soil and the rest pine bark chips. I water it everyday. Leave it in bright shade for a week and water it everyday. If it gets better, slowly let it acclimate to sun again with the same water schedule. With the hot weather, i think u should water it everyday. Just make sure it is right porous draining soil. They are hardy dont worry. Dehydrated is a lot wasier to save than rot rot.

I use sand, perlite and coco peat as soil. Im watering it every other day now, and snip off the leaves on top to let it grow again.. still looks the same to me..

can anyone tell me why i can as though see the water level in(side) the caudex awhile after i water it? is it normal?

I'd like to see a photo of what you mean by "see the water level inside the caudex". I would not have removed the leaves when the seedlings are already under a lot of stress. They needed those leaves (which looked healthy) in order to recover. I guess we'll have to see.

The water line is visible. Is this normal?
Sorry I’m a beginner in gardening and it’s my first attempt growing them from seeds..

Hi Julie. Don't worry, we got this. (well, I hope). The most important thing to remember is that you are in SEA; that will make this easier to pull off.

In contrast, I am in USDA Zone 7 where SEA-like weather lasts only about two to three months. Right now, I have a couple of seedlings from my own plants and they look like this:

Note that i have my seedlings in heavy soil. This is because at this age (about 6 months), adenium seedlings need a lot of water. Adeniums are really not succulents until they are maybe a couple of years old and even then, only in winter. This is the reason why most lazy growers (like me) plant them in very loose medium---it makes it easier to water them sporadically in winter and still allow them to dry fast enough.

Where you are, evaporation due to the heat will dry your medium much more quickly. That is why they were drying out. They had reached that point where the medium you were using was not able to retain water long enough to keep up with how much water the seedlings needed considering how hot it is there now.

So, that's the general principle. Now, what to do with your seedlings. If you are daring, I would move one of them in just normal soil. That's what I would do if I lived where you are and if these were my plants. They have no leaves at the moment so I recommend putting them back in bright shade (not indoors, they need the heat) or dappled sunlight.

I have to warn you that the visible water line on the trunk of the plants do not look good---that is typically a sign that they are not properly absorbing moisture. But I have seen seedlings bounce back from this so all is not lost.

Your seedlings are beautiful! How did the trunk got so fat?

I have transplanted one of my mine to normal soil like your suggestion. I left both plants in bright shade, they would get afternoon sun for about 1-2 hours. Hopefully it'll work. Those 2 were my first attempt, that is why I am more attached to them than the rest of the seedlings..

Could you please look at these seedlings of mine? I left 4 seeds to germinate in this seedling container of 2" x 4" about 6 weeks ago. Only 3 was successful. I left them in bright shade since Day 1.

Is it time to repot them? Any recommendation for soil? And how to get fat caudex like yours?

Sorry my mistake, not 1-2 hrs. It’s 3-4 hrs of afternoon sun. Should I put them further away from the hot sun?
