You could try cutting it off at the top of the bulb to encourage new growth... My mom had them but I haven't been able to get a hold of her to ask if this is what she did.

As you can see in this website, cut back your watering and reduce the foliage.

Thank you Ianna. I did it now can only wait for results. I hope a flower stalk shoots out! Tho I am good with many plants I am not able to nurture some types successfully. This is first try with amaryllis. Thank you.

I stop watering mine entirely in November & store in a cool location....5-15 degrees. In January/February, I bring them out of storage one at at time and begin watering. The leaves are yellow by that point and they begin growing the flower stalk.
