Read al's account of his plant for physan dosage... Personally I have
a bottle of the stuff but have never used it.

remove the leaf and cut away as much of the black as you can reach)
and then dust with cinnamon

under 'fungicides' and 'crown rot'
if however the black area is hard and dry, i'd just rinse it down with
H2O2 when you repot and keep an eye on it.
Thanks. Repotted it this morning. While the black area feels hard,
the leaves that had it came off easily. Not good I'm sure. I will
take your advice about treatment.
