Hello,
I have a Adenium obesum and have had it for years. Always been in good health. Make sure not to over water, gets brought inside when it gets cold, It receives the correct amount to sun light and I turn the pot every week.

Im having an issue with the tips of the stems and leaves turning black. It happened for the first time a few months ago and I just pruned the effected areas and new growth came and it looked good. But it is now coming back again.

I researched stem rot and leaf rot but I'm not sure if that is my issue or not...

Thanks for your help.

Welcome!

That black stuff looks like mildew. Is it getting good air circulation? If the air is stagnant, plants will mildew.

If not mildew, maybe mealy bugs or soft scale. They tend to gather in the leaf axis and they do produce honeydew that will mold. I would try cleaning it with a Q Tip dipped in alcohol. If it's bugs, you will see them.

I would just cut off those blackened tips, apply some cinnamon on the cut end. Let it dry.

Your tree is going dormant and I don't know if it is getting some cold draft too. Try to keep warm and dry. I would also check all the underside of the leaves, sometimes it may have harbored those nasty critters, just use cottow swabs with alcohol to remove them.
