sounds like one of the bulbs rooted. You can take them out and wash them off and then replant the good one, it should not hurt this plant which is very tough.

thanks. Can I wait until the flowering bulb (in the same pot) is finished? or is it urgent? Joe

I started to take soil off this root. I got about halfway down the bulb and I was in danger of breaking roots,and I didn't know roots of which bulb. The bulb itself looks fine - firm, white. So I filled the hole with perlite and will only water when the leaves on the other bulbs start to wilt.
