Amaryllis and Hippeastrums: Confused as to when to repot my amaryllis, 1 by mygardens

Someone gave me an amaryllis a week before Christmas. It came in the usual, light, container with some kind of soiless, potting medium. It had 2 stalks and one is still blooming. I have read much information about how to feed and maintain the leaves and what kind of soil mixture to use when repotting, but I am unable to find out when to repot a bulb like this. Do I repot it now and let the leaves grow, or do I leave it in it's original container, let it grow through the summer, let it go dormant, and then repot it in new soil for next years bloom? Need to keep this bulb from dying!
