I had the bulb tested and no virus!  I live in california. I also grow haemanthus katherine. They are growing in the ground, I dug them up to relocated them and noticed that the lower part of some of the bulbs were rotting, its been really wet and cold this winter. Is this basal rot? It has new white roots coming from the top of the bulb. I want to more them into containers with more perlite and sand. Toss them, try to save them?

I concur with Jim.  When leaves die back they can look rather nasty and
sometimes yellow at an irregular pace.  I wouldn't cut the leaves.  I would
simply allow the leaves to senesce naturally.  Before it goes dormant he
might give the plant an imidacloprid drench for safety's sake because
mealybugs can spread virus even when bulbs are dormant.
