rot? ugh

One of my african violets has been looking unwell- the younger purple one.

I brought it downstairs when I was doing a bit of repotting the other day and started pulling off the outer, anemic leaves. Thought it had gone too dry when I was away for a bit a while ago, and then perhaps overwatered when I returned? But suddenly the remaining crown broke off in my hand.

The center of its underside looks brown and diseased.

If this is crown rot, it's caused by a pathogen- I cut away to healthy tissue, got a new sterilized pot and fresh soil. Crossing fingers it recovers.

(And my mail-ordered leaf cuttings have still not grown, btw)
