Hi saima,
It sounds like you have done everything you can for the rot problem. If you still have green leaves,pot it up and give it a chance to regain strength. Plant it very high in the pot with most of the bulb above the soil.You should probably stake it as this will make it top heavy.
Can you describe the creatures you found? Are you sure they are slugs? Lora

hi...
thanks fo r the adivce. they were like slimy light brownish....slugs?..some were b igger and fatter. im guessing they came in with the soil when i brought the amaryllis from outside. i should have takena picture. im sure ive gotten rid of all of them fromt he bulb..unlesss there r eggs? im gonna kee o the bulb for a few days on my sink. maybe i'll pot it up after im sure there r no more creepy crawly things.

thanks
saima

HI saima,
Could be slugs,could be Narcissus Fly. The dratted slugs here usually eat the roots by day and leaves by night.They dont seem to actually chew into the bulb though. Lora

But isn't the bulb toxic to animals? Or slugs and the Narcissus Fly are immune to this toxic material? Or maybe they thrive on it? How interesting.
