Does anyone know what this stuff is on the intersections of the stems? I don’t know if it’s a fungi. It’s mostly a hard substance, but I can kind of put my nail into it. The plant doesn’t seem like it has pests, but I feel like it’s been dropping a lot of leaves and maybe the stems attached to this substance seem to be shriveling? I got this plant from my aunt about 2 years ago, so not sure when it was repotted. I was thinking of doing it today, but want to know what this is first. I haven’t noticed anything unusual but my gut says I don’t think this should be here. Should I be concerned? The leaves and flowers that dry up and fall off seem to be normal Update: Planta doctor says it’s corking (and a bit overwatered). I don’t know anything about corking, but it says that’s fine. Is that correct?
