Could you please post a photo?

The new potting mix could be still water retaining. It is in large pot that will take lots of soil and more water retaining soil there is, much longer it will take to dry up. Roots get damaged because of that.

Dropping branch is bit worrisome: did you check the stump left and the dropped branch if they are soft? If so, there could be rot there. I do not see much of other reason for branch to drop. Could be if it dried up, but that takes a long time, your plant doesn't look dry to me and the soil doesn't look like it has been dry for any length of time. If branch is drying up, it would shrivel a lot. Do you still have the branch? You should cut a small piece of it from where it was attached to the plant. If you can take a photo of that cut, we may be able to tell you what happened to it.

Did you have any roots left on the plant after first 'rescue mission' :)? How soon after potting it up into new mix did you water it? What is in the potting mix? - I think I see some perlite, is there anything else?

The stump and the dropped branch was not soft, just a little shriveled. The branch I have and is now being propagated. It is doing well in a new pot with a few other cuttings. It has been over month since repotting it and i had just watered it so thats why it doesnt look dry. I thought maybe that it was to dry and thats why it had dropped that branch. I did have roots left after repotting and had waited a month to water. I also let it dry out in the open until the stump was dry before putting it in its new pot. Many of you have said to do that so I hope that I was correct in doing that. The potting mix is perlite and cactus mix only. I would like to cut the plant back to the barky sections and propagate it but with what is happening to it do you think i should wait? Thanks for your help.

If my plant. I would prune some more branches off and root them separately. BUT that's me. I don't want to advice you to do something that may not work. I am confident it would, but plant should be healthy enough and I really can't tell for sure just looking at the photo.

What you did sounds good to me. Problem that could happen would be if there is rot somewhere in the plant - doesn't seem like that was the case.

Branch could have fell off because it was dessicated - again, difficult to be sure since I can't see it. But you say it is doing well.

I like to use more inorganic mix, made of grit and perlite and some turface (or could be small bark)

I can't see a saucer under that pot, makes me think if hasn't got any drainage holes? At least one is a must.

There is a saucer under it you just can't see it from that angle. Where would you guys cut this plant if it was yours?

I would probably cut off that thick branch - cutting it closer to the trunk so after scabbing there is no sump. I would do the same with stump opposite of the branch (I am thinking that's where branch broke off?):

Yes, there shouldn't be any black or brown in it. Keep cutting until you don't see any more.

What did the other branch that dropped off the plant look like on the inside? Was it similar to the picture?

It looked fine. It's rooted in a pot but the stump came off today and it looked like that.

That is rot...and it usually continues thru the stem. How is the cut right at the stem - if I understand correctly, the stump fell off and had same dark markings. Is the photo showing branch I said I would cut? If yes, how far from the main stem/trunk did you cut it? Is there a photo?

It had that rot continuing into the stem/trunk of the plant. I just cut off all three branches until I didnt see anymore rot and are going to replant them. Hopefully they root and I can at least keep that much alive. I also think that it looks a lot better now. Thanks for all the advice because i would have lost the whole thing and that would have been awful.

Make sure you keep cut branches dry - even after potted in fast draining mix, resist temptation to water! Jades will recover from under-watering much easier than from over-watering. Good luck. Hope to see follow up photos.
