Hi Community. I’m looking for a little help with this family of cactus I’ve inherited. One part of the cactus has been facing away from any natural light source and has noticeably sagged. It also seems to be suffering with a thick white mold. I’ve used some cotton buds/q tips to gently scrape at the mold and the flesh of the cactus underneath feels spongy and comes apart easily. I’m a rank amateur so not sure of cause or solution. The rest of the family seems okay for the moment. Any and all advice appreciated. Thanks!

    Could it be overwatered?? You should check the roots. And I personally would remove the dying part. With it soggy and moldy, there is no coming back from that unfortunately.

    Assess the roots for sure. If those are rotting, your odds of saving the root mass are very low. If that happens, restart it as a bunch of cuttings. How to do a cutting: Use puncture resistant gloves for handling it. Sterilize a saw (wipe it with rubbing alcohol and let it air dry) and cut straight across, at least 1 inch above any visibly rotting sections. Lay it down on a clean surface (i use paper plates) and allow the cut to callous over (this may take anywhere from a day to a few weeks depending on plant girth and growing conditions.) Once the callous is healed, pot it up in fresh cactus soil, burying about 1/3rd of its total height or as much as will fit comfortably in its new pot. Water it in and then continue normal care (just avoid overwatering). Also when doing cutting from rotting material, re-sterilize your cutters between each cutting so you have a lower chance of spreading the disease to a healthy cutting if you happen to cut one too close to the rot. If the roots look okay, then remove all diseased sections with a sterile knife or saw. Monitor the wound while it callouses and treat with hydrogen peroxide if it looks like it's starting to rot.

      Thanks for the thorough response. I really appreciate the detail, I’ve never had to deal with a situation like this before.
