thanks
@Deepsouth and
@GigiPlumeria for all your expert advice. I will follow your instructions.
Here it is today:
Some leaves are yellowing and dropping.
The smaller one is Desert-Rose Adenium-obesum-subsp-swazicum from
@Gerris2. It has lost almost all its leaves.
I'm feeling very hopeful that with your help, I can grow these plants.
