I just bought it and transplanted to a larger container. Used soil made for it.. was careful not to disturb roots. I left it in shade for 7 days and then moved to sun .. we are in Florida. We have had a few cold snaps.. not freezing. We had one full day of rain. It does drain well

I should add I did check out some of the fungus types that impact.. and it seems the leaves go yellow then the spots appear.... my desert rose's leaves remain green..... the spots appear THEN go yellow .. the undersides are not impacted until later As you can see in the photo - this is same leaf

You didn't say what part of Florida you are in but the black spots on the leaves of your Desert Rose (Adenium obesum) may be a fungal issue due to wet and cold weather we've had in some parts of the state lately.

I know the seashells are pretty but I'd advise removing them from the pot unless you can be certain that they aren't leaching salt into the soil.

Why were you in such a hurry to repot it?
It just adds stress to the plant.
You buy it and bring it home to your conditions. That stresses it to some degree. I would have let it adjust a little to your conditions. Maybe repot it in a couple of months.
Then you repot it immediately! That adds more stress. And having stressed it twice within a very short period of time, it is no wonder the the plant is showing signs of being unhappy.
I preach going slow with a new purchase.

I bought it from a nursery 5 blocks away... conditions the same

I repotted it because the pot was too small and I am a snowbird.. when I leave it with a sitter in a few weeks, I wanted to leave it in the pot it requires. I won't be returning until next fall.I was careful to not disturb it and used recommended soil.

I am in
Punta Gorda..we have had to run the furnace a few times since I purchased it
The seashells .... I never thought of the salt aspect... I will remove! Thanks.

If you look at Desert Rose images on line you'll see many of them growing in very large containers or tubs. They have these huge calluses or big above soil tuber type deal. They really flower well in tight containers.
They are tropical plants so I doubt that the nursery in NC had them for very long.
But regardless, mine in Florida loved the heat but didn't care for more then 3-4 hours of direct sun. The sun is just too strong down there. Mine always dropped their leaves in October/November and put on new ones in early February or so. They seemed to flower better for me when I gave them a teaspoon of slow release fertilizer. I used "Dynamite" 20-20-20. I gave that to them when they started putting out new leaves.
I got flowers on about 50% of the branch tips and 5-8 flowers per.
Good luck with yours.
They rot easily during the rainy season, especially if drainage is compromised.

If it were mine, I would just continue to position it indoors by your warmest/sunniest area and kept dry. It will continue to drop its leaves. Looking at it, it has already started to go dormant. Even if it continues to bloom it is dormant, unless you actively see new leaves forming.

My Adeniums usually start to wake up when overnights are more stable at 50F and daytime highs going 75F and higher, light levels going longer duration. So I really have to wait patiently for outdoor conditions to warm up nicely.

Thanks for the info.
I will get the fertilizer for future use..

I purchased it in Punta Gorda.. 5 blocks from where we live winters.
It was in a way too small plastic pot ...wanted to size up ( not a huge pot or great difference ) before we leave for N Carolina. It will stay here in Florida . Fort Meyers address with a family member.. I wanted to transplant a month before we leave so I could see it settled.

I figured if it hs started to bloom not dormant.
It gets about 5 hours sun at its current position.

Thanks for all the advice

You are very welcome!
