Now that your amaryllis bulb has finished blooming and you have cut off the spent flower stock at its base, continue to water the bulb and allow the foliage to grow. The foliage is taking in nourishment for the bulb. When the foliage turns yellow (which should not be for a couple of months), cut it off. Store the bulb in a cool dark place until it can be planted in the garden in the spring after the risk of frost is over.
