Have you tried saving a rotting bulb? The rot is in the middle of the bulb where the leaves form.
I've been searching the net and found a few articles but I want to know if anyone here had success and how you did it.

It is a Scilla bulb - Peruvian lily which I just purchase this spring... it had a gorgeous bloom. Hate to lose it.

If the basal plate is intact you could always try chipping the bulbs and dipping the chips in fungicide.

That's what I ended up doing...hope it will work.
