Hello!! I purchased a large desert rose plant early this spring, I live in Florida 9b. I repotted it immediately because it was splitting out of it's 3 gallon nursery pot. My soil was about 40%perlite/ 40%course sand/ 20% compost soil. I used terracotta pots, left it in the shade for a few days before watering it, then I moved it to a fairly sunny location it was doing great. Unfortunately, we had 3 straight days of downpours about a week after I moved it.
Heres where the problem started. The leaves never turned yellow, but it started aborting buds. The lower part of the caudex became soft(not squishy). The upper part of the caudex and stems were still very hard. I unpotted it and there was a small portion I decided to cut off because it was grey and mushy. The cut was about an inch long. I let it dry (unpotted) for a week and it looked amazing. The cut was dry, all the buds were flowering and the leaves were strong and deep green. I decided to repot it at that point with the same mix of soil, but I added gravel. After 2 days my 3 yr old poured a bowl of water in it, I thought it would be fine... after 2 more days the roots were getting softer and the cut, that I thought was healed, was obviously rotting. I unpotted again and cut off all the rot, but it seems like everytime I cut it almost instantly browns like an apple would? I put ground cinnimon on the new cut and it's been drying now for 3 days. The leaves are dropping now, I'm guessing from dehydration. The roots are still so very soft, I'm hoping that a normal part of the drying/healing process and it will heal properly with time. Also, if the surface seems discolored anywhere I am able to scratch it revealing whiteish or green flesh, not brown or yellow. I hope this all makes sense, I just don't know if I am doing enough. I dont want to lose this plant 😕

It is rot and you have not gotten ahead of it. You can keep cutting and hoping but I think that it will not recover.
It has been my experience that the rot spreads very, very quickly and just when you think it is under conttol, it has already progressed way beyond and past the point where you think that you have it beat.
I would toss it and start over.
My potting mix was 50% sand and 50% potting soil.
I lost one in Florida due to a clogged drainage hole. Rot started quickly and even though the root mass was as big as a basketball, it was dead inside of 3-4 days,

I agree with BigBill - root rot

Root rot is hard to recover from ...but not impossible to treat .....

First gather your cutting instruments (an Xacto type knife with assorted blades or a double edge razor) ....a bottle of rubbing alcohol and a few rags

First step - Use an Xacto blade to cut out all of the soft mushy stuff .... before moving to a new spot to clean out or cut, rinse blade off with alcohol and dry with rag ...

Remove anything that isn't white ....
Your picture with the caption "2nd cut 3 days old after 3 year old watered it" .... remove this root all the way up to where it joins other roots .....

Next - wash off root mass - let dry 1 to 3 days
Next - sprinkle fresh ground cinnamon or anti-fungal powder on cut areas and allow to sit for a week to 10 days -

Then re-pot .....

Here is a tried and true potting mix for adeniums

Mix together:

2 Part: Coconut Coir -
1 Part: Poultry Grit (chicken grit) /or Pea Gravel - (sift out any fine grain silt)
1 Part: Sand - coarse Builder's Sand, or Leveling Sand, or Horticultural Sand - (sift out any fine grain silt)
1 Part: Lump Charcoal - Break-up (crush larger pieces) - (sift out any fine grain silt)
1 Part: Lava-rock – (volcanic cinders or pumice) (crush larger pieces) - (sift out any fine grain silt)

Optional: mix with above

1 Part: Redwood Bark / Orchid (Phalaenopsis) Mix - Break-up, cut or crush larger stems & bark
1 Part: Perlite - coarse

In a Adenium re-potting mix pinch?
Can substitute regular Soil Mix for Coconut Coir

Can safely substitute a half and half mixture of Orchid / Phalaenopsis Soil Mix (mostly bark and rocks)
mixed with Cactus / Palm Mix
(both available in bags at most Big Box Building Stores)

Once re-potted raise the pot in such a way that any water added to the pot flows freely away ...

Thank you! I decided to go ahead and give cutting a try like deepsouth suggested. It will be a learning experience at the very least 🤷‍♀️. I was able to save some small roots from the top otherwise she got a BIG chop. Everything is solid no softness whatsoever. Here's hoping!🤞

Is it possible for one to re-root if you have to cut all the roots off? Mine's in terrible shape.

That should grow again with a little care. Jus take it easy on the water until it leafs out again. This is prime growing season with the summer heat.

deepsouth, in your potting mix recipe, when you say "lump charcoal", is it a particular type of charcoal, or can I go into the grilling section of the grocery store and get the wood-based natural charcoal (not the match lite briquettes)?

Yes ...available in the grilling section of most stores ....

lump charcoal is 100% hardwood (even looks like wood) -

charcoal has been used as a fertilizer for hundreds, if not thousands of years - mixed with soils - it also improves drainage ....

and ...what you do not use in mixing-up potting media ...you can use at your next BBQ
