We have had this succulent on our kitchen counter for almost 14 years, but it was in a very small cup and needed a better pot with more space to grow its roots (some of the leaves shrivelled and fell off), so we re-potted it a few months ago in ProMix Cactus soil. The top had grown and curled over and then back around to be pointing up to the sun and was supported by a twist tie on a wooden stick at the top of the bend, but a while after re-potting it, the top part of the bend started to turn soft and less green, and eventually it broke off. We took the piece that broke off which still had big green leaves on it, cut the end, and planted it near the main plant in the pot - there's no indication right now if it is growing and rooted-in or not, but the leaves are still green. However, the other side of where it broke off at the top of the main plant has just now gone from being green and hard like the rest of the plant to being less green and soft and it looks like it is traveling down the stem towards the main part of the plant which is quite concerning. What do I do to stop it from getting soft and to save the plant? Should I cut that one section? Or could it then just keep traveling down and toward where other leaves are growing out of it? I wouldn't be able to cut that section completely down to where the plant is healthy, because there is a stem with leaves growing out of it at the base of the part that is starting to rot that I don't think would be good to cut off. We were thinking of maybe re-potting it into better draining succulent soil today since the cactus soil it is in right now is actually quite dense and not very well draining, but I don't know if that is the problem or how to help it otherwise with the part that has turned soft. I also don't know why the top section between the main base of the plant and the other leafy chunk turned soft and broke off in the first place after putting it in its new pot. I would appreciate any advice since we have had this plant for so long. Thank you for your help.
