I am begging for advice! I have a 12-14 year old jade plant that has been healthy until recently. I recently repotted in a mixture of soil, sand and perlite. The plant began to droop and sag and I noticed a couple of branches were soft and appeared pinched. After removing the branches, I found them to be hollow and black inside.
From my web searches, I believe it to be bacterial soft rot (though I am not positive and cannot find images to support this). Is it possible to treat this plant? How can I stop this from happening?
It may seem silly but this is so much more than a houseplant. This is the only surviving plant from my husband's late father's collection. In many ways it feels like our only living connection to my father-in-law who was lost too young, nearly ten years ago. I am terrified I have killed this plant and am willing to try anything to keep this alive for my husband. Please help. Any advice is appreciated.
