Hi, I have this cactus- I don't know what kind or species- but after recently repotting it, I've seen it sort or wilt and deflate. It was an offshoot on a parent cactus, so it had no roots to begin with, but it is about full size from what I can tell by comparison. It's in a mix of cactus soil and sand, and I may have watered it more than necessary. Can anyone identify the problem (even the cactus...) and remedy? Thanks
Hello @StephenOs and welcome to the forums. I think you are right that you have overwatered this cactus and, unfortunately, it is beyond remedy. If you should start another cactus from a cutting, follow the advice given on this website or another that explains in detail how to do it. How to Easily Root and Propagate a Cactus Step-by-Step.
I thought that since the cactus would probably die, I'd have a go at reviving anyway since it wouldn't hurt. When I took it out, it was actually green below the soil line and was starting to root. It was certainly neither of these before I planted it originally, so I've put it back and I thought I'd just let it dry out...
To increase the chance of this surviving, you should cut off the rotten part including an inch or so of the part that is still green. Hopefully that will stop the decay from moving into what seems to be healthy. I wouldn't hold my breath.
