I have heard of some people trying with Haemanthus bulbs but they have to
be soaked for a long time at high temperatures so that they are heated all
the way through. Many bulbs will often suffer from that high heat treatment
and many don't survive. They might have a better chance if they were in
tissue culture with more coddled conditions. The moral of the story is that
prevention is much easier than treatment.
