Need advice:trim suspicious area off?
I was checking on several bulbs that I have growing under lights, and the one pictured had turned a different color from the others, and then I saw the start of rot at the base of the leaves. This one is mandonii, and I'd hate to lose it. Fortunately it's produced at least two rooted offsets. I only noticed this as I was running out the door to an appointment but the plan is to peel off the bad part and treat it with physan as soon as I return in a couple of hours.
Assuming/hoping that any rot doesn't extend into the core, how deeply can I peel into the top of the bulb without killing it? If the rot does go deep, is it best to try to extract healthy parts of the basal plate and see if offsets can be coaxed from it, a basic sphag-and-bag?
Any first-hand experience with this would be greatly appreciated.
