FYI: the red spots appeared on the leaves quite a while ago, but i didn't think it was anything to worry about at the time. This was actually more than a month ago when they were still outside....
I cut off all roots on one bulb and dipped it in a fungicide solution. See if it works.
These bulbs are not too hard to come by, but it's still a shame if you can't keep the same ones year after year...they're like children to me already. Does that sound overly dramatic? :p
