The flowers in my amaryllis grew and were cut off. It is now February and the foliage has died. What do I do?

Mine are planted in the garden, so I go thru this every year. I just go ahead and cut the foliage back in the fall and new growth appears usually during January. If the foliage has only now died off, I would cut it back, continue care are usual and see what happens.

I normally cut off the dead foliage. Then I dig them up and put them in a box in a cool dark place then next spring.
