Paula: Sounds as if your bulbs are doing OK in the attic. There isn't a rush to take them out, though once you're past 8 weeks you can start to bring a few out every week. I wouldn't keep them in longer than 12-14 weeks, get them growing again. Just check occasionally to be sure that the bulbs aren't showing signs of rot. If the bulbs do show signs of top growth while in the attic: Definitely get them into light at that time. The usual recommendation is to repot with fresh soil, water , put into light. Don't water again until you see top growth. You don't need to fertilize until they are done blooming. Fertilizing is pretty much done by personal preference. Some books say fertilize 3 times a season. Some say, fertilize with a very dilute solution every time you water. Amaryllis will eventually bloom, if not on your schedule, then they will bloom in late spring, which would be their normal time in the North. What you are doing with forcing dormancy is tricking them into thinking that they have come through winter, and its time to bloom.
