Hate to admit it, but it reminds me of some of my plants lately. Never
thought to take a photo of them.
My problem is minor (dry climates can be a good thing), usually only on new
plants, and tends to start from the base of the main fan. It happens most
often to those tubers that have been sitting in a bargain bin at the
department store for too long, that I buy anyway, and that get planted in
November or December. This year the rains shifted the soil in some of my
new beds, and caused a number new starts to be buried too deeply in my
alkaline clay soil. I didn't notice till it was too late for some. The
ones that were washed out are fine though.
Not sure if I have the same rot as in the photo. It usually tan in color
and turns the rhizome into what looks almost like a powder (until you touch
it, then it glops into stinking tan slime). If I catch it in time, a
cleaning out of the dead flesh, a soak in bleach solution and exposure to
dry air usually stops the rot dead in its tracks (great for big tubers, but
I usually loose the smaller ones).
