BUT I was given a Hippeastrum last April, from Holland, and it had a grey fungus. I found it right away and threw the bulb away, as the fungus was all around inside the bulb. THAT was a bad one, but luckily no other Hippeastrums got infected, though there were several in the same room for a week or two. Indoors I don't get any mites or anything - loads of spiders and such though! Carol
