I got this plant at a moving sale a few months ago and it’s been just getting by. It keeps losing the leaves from time to time, shows no new growth etc.
I suspected root rot and dug it out , and the bottom of its stem is concave — like a volcano crater with a deeper point in the middle and higher edges (if you turn it upside down).
What can I do for it ? Basically the roots in the middle are barely touching the ground.

And overall , ALL roots this plant has, feel dry , like a brush wire and you can break it away they are all DRY !

So, there are no live roots ?
How this could have happened ?
The plant was in my care for the last 4-6 months, I watered it maybe twice a month , the stem looked normal not dehydrated .

I only started digging it out because it looks stagnant with no new growth.

The plant is indoor, on the south -east facing window in an apartment building . Has good indirect light 8+ hours each day.
I repotted it with fast drying succulent soil .

Help help help pls ! :(

I found no significant rot , only some soft-ish pieces which I cut out. Now only white firm flesh is there. It doesn’t look white because I put some powdered cinnamon on it to prevent bacteria .

Got this mature Jade at a moving sale, how do I revive him? It has reddish spots throughout perhaps half of its leaves .
I googled and it says sunburn ?
Also , it’s an older plant with a lot of empty branches . If burned leaves die off , the branches will look like long empty rods with a few leaves per each …

Also, some background … it came to me in a large pot with a main parent plant . It was trimmed a lot and it came wirh its own propagated cuttings with established roots planted in the same pot.

I’m not sure what previous owner tried to achieve …
Maybe it was one mature jade with long and /or empty branches , and the past owner wanted to prune it, trying to make the main plant grow fuller .

With the cuttings , they didn’t do much just let the roots grow, planted in the same pot.
So now there are a bunch of awkward long branches trying to be standalone plants but all are so out of balance.

The only thing I did so far was I separated all pieces and main plant , that’s what you see in the pictures ..

To summarize the problems :
- half of the leaves are “sunburned” or whatever it is ?

- many leaves (including healthy ones ) are too large, with surface of 3x the size of an average jade plant leaves you see in stores

- many bald spots, empty branches . I imagine the view when all burned leaves die off .

Help me 🙏 😭😭
I truly want to rehabilitate this dude…
