I'm not sure where my first reply went, so I'm going to try again: Nope. The name on the tag was "Baby Jade: Crassula Argentea". I'm not sure if it's 100% accurate but that's what it says it is. :)

Not quite sure if it is K. thyrsiflora - bit it could be difficult to tell when plant is small. Here is the photo of my K. thyrsiflora that lost 6 large leaves from sunburn and perhaps over-watering too, (it is small but probably bigger than yours) - the leaves are little more round. Red edges are due to more sun:What is the other plant in the same pot? Do you have any other similar looking succulents? Is it growing in relatively dark spot?

If the roots are healthy, I would not cut them off. Any soft spots on trunk? (it looks good in the photo). If my plant, I would try to tease out rest of the soil from roots (using tepid water helps to soften the peat, and help yourself with a wooden skewer) and inspect them - if any very damaged and/or soft-mushy-slimy, I would cut those off. I would dry off all the water (the leaves look too wet to me - did you soak whole plant?) and pot it up (I use mix of grit+perlite+turface). Give it bright and warm (not drafty) spot and wait patiently for roots to grow in.

wow! I'm glad I asked. I was about to cut up the other one, too. So, just to be clear--I have the two sister plants--one that I cut up, and one that I held back on. I agree with you that this looks similar to underwatering--but I do remember it looking a bit underwatered not long ago, and giving it lots of water to perk up, so I'm fairly certain that it's overwatered (especially since I'm squeezing water out of the wilted leaves). Just to make sure--despite that the very bottom near the trunk is quite squishy now, judging by the inside of the sister plant after I cut it up, maybe I'll hold off on cutting up this one for the time being --- but I should trim the roots of BOTH plants (?) here is the plant still in one piece, that currently still is squishy on the base stem right near the roots: And if you're curious, here is everything I have from the sister plant that I already cut up (i assumed the base trunk was rotten, so made several mini trees out of it)--I assume (hope) I cut them in a good spot, but can still correct if it doesn't look good: Per your suggestion, I trimmed the little portruding piece of branch off the trunk and see if the trunk comes back to life (maybe I got too close?). Here it is now: I think the cuttings for this are clean and not rotting. They are basically firm. Maybe I'll give them a little bonsai wire in addition to some rocks so they can stand up... As far as repotting--the rocks in the white container were just decorative on top of the soil, and just got mixed up. I use 50/50 perlite/succulent soil---in fact, I think you taught me that a couple of years back! :) .... I would be curious if you have an opinion on using rooting hormone on the stem. I notice in your other thread you suggest cinnamon... would either one suffice? Here is what I have: also--some websites--including some of the threads here--say that I should wait to repot until roots are showing.... but that could take weeks, I would think. Is it ok to repot without roots? Maybe I should use more perlite in that case (75/25)? Anyway, thanks again! I'll be interested to know your final thoughts, and I'll give you an update down the road and let you know how the jades are doing!!!! :)
