Narcissus 'Quince'

Another way of cleaning up virus infected bulbs is by heat treatment. It
undoubtedly varies by bulb species and pest species, but 55 C for an hour
is perhaps close to what you can do. Rather than discard valuable but
virus infected bulbs, try heat treating them first.
I don't know, does heat also kill mycoplasma?

But is it virus- and nematode-free? I suspect that 'Quince' is one of
those cultivars where all the commercial stock is diseased;
'Tete-a-Tete' is another such. I'm hoping that someone out there
has clean stock of 'Quince' or has run some through meristem culture
to clean it up.
