Need help with rot on caudex in adenium
I have an adenium (obesum i think?) that has some rot in the caudex. What happened is some rain accumulated in a dimple on the caudex and apparently rot set in. You couldn't really tell unless you looked closely but when I touched it i felt a bunch of vertical soft necrotic tissue. I immediately tried to remove all of that but it went pretty deeply. I got what I could and sprinkled cinnamon in there (internet tip.. good thing?). I've been watching it for about a week. When I probe back in there I can still feel some soft tissue but it seems to have healed for the most part and dried out. I've kept it out of the rain and let it dry out (not watering for now).
The main problem I'm having is that the entry point is narrow but goes back pretty deep so it's hard to tell how things are going inside. The plant still looks healthy but I've had a few leaves yellow. I want to be proactive. I've considered cutting a wider opening so I can open it up and get more airflow in there and also get a better look to make sure I'm getting all of the necrotic tissue out.
I'd really appreciate some of the pros here guiding me. Thank you so much for taking the time to help. I've attached some pictures.
Apologies for any stupid questions or misnomers. I'm an amateur with these.

caudex rot
Comments (3)Joe, My apologies, I just realized I gave you the wrong link. While that one does reference a damaged caudex, it was not the one I had in mind. I will look it up later. Let me share my experience this yr: I also have a variety of fatties. Most I keep on the porch where I can control their environment better. But all the Adeniums have been in out in the elements. *The Elements" in Texas have not been kind to succulents this year. We've suffered with non-stop rain/overcasts skies since March; at one point we had 48 straight days of rain. A real oddity. I've had mold on the outside and 'shrooms on the inside of my pots BUT of the 200+ plants being rained on every day, I have had only 2 starters to rot. I attribute this fact to the sharpness of my soil. (G*d Bless Haydite!) Without knowing what plants you are growing, the type soil, light, watering, etc, it is impossible to speak to your problem. Does the rot start in new places? Or continue to rot in the same location? Is it rotting from the bottom or are you noticing unhealthy branches/leaves? Please give us more information and a pic is most helpful. Jo...See MoreMy Adenium needs serious help, please.
Comments (109)The best thing to use is actual soap (castile or other), which is distinct from detergent (ie: dawn and friends - if you look carefully you'll see they never use the word soap on their labels). Often you can find peppermint castile at many places, but there are other kinds of real soap as well. Detergent has been shown to have some effectiveness, and is often recommended, but it's not soap, and is more likely to contain chemicals you might not want on your leafs, and is likely less effective than actual soap at deterring/killing your pests. any kind of "insecticidal soap", like that sold by safer and others, is made of real soap and not detergent. I think it's likely the curling/misformed young leafs in your photos are caused by whatever is there, and if you don't address it will get worse. Leafs like that are usually caused either by pests or some kind of nutrient uptake issue caused by salt buildup in the mix [too much fert, not enough flushing], overly alkaline irrigation water, or other reasons.

Comments (17)Crenda, have you cut it further yet? The red line is where I would start as well, in which case you might be able to save (part of) that top root that runs along the line. I fear however you'll end up nearer to the potting line (where the dark green starts). I hope I'm wrong though. Let us know how you get on....See More- 6 years ago
I took it out of the pot. The roots look super healthy. No rot. I did find more rot inside the caudex though. The small opening combined with the depth is causing a dark, warm and humid environment which is clearly not good. I went ahead and opened the opening wider. Upon doing that it had gotten so deep that I went ahead and decided to open in up on the other side through the healthy tissue. It was several inches deep into the caudex and only maybe half an inch from the other side. I opended it up to get some airflow and it allowed me to clean it out more. I heavily dusted the inside with cinnamon powder. The question now is how long to leave it unpotted, and where? I've been hearing a week. Should I leave it somewhere that it will get some sunlight? Or will that damage the roots? Can it just lay on it's side or does it need to be suspended in the air by string/twine?
I think If I can get it to heal this could eventually add a lot of character to the plant as it callouses over and grows.
Thoughts? Thank you!

5 years agoWhenever you spot the rot immediately take the plant out of the pot and with sharp knife remove the brown rot part until you reach the healthy part of the caudex then apply pest of copper oxychloride as shown in the picture and leave it for few days and then repot the plant in fresh potting mix which has high drainage quality. Copper base fungicides are the best to control such rot.
