I bought an amaryllis bulb in Amsterdam this October. Instead of potting it in soil, I placed it in a bowl on top of rocks and have been keeping the roots (but not the bulb) wet, while changing the water every 2-3 days. It's been blooming beautifully. But what I wonder is how to care for it to rebloom for next November/December. I've read instructions on what to do for amaryllis bulbs after they bloom that were potted in soil, but what do you do for such bulbs that were potted the way I did it?
Also, I live in an apt in NYC, so I can't move the bulb outside during the spring and summer, though I can place it in a sunny spot. Any help here will be greatly appreciated. Thanks!
