Hi, I think this was answered on question 19251

just to add to the post, we find that they reflower when they are almost pot bound, dont be in a rush to replant them, about a centametre of spare soil around the bulb is plenty, dont be tempted to take the bulb out of the soil and dry it out, this used to be done when greenhouse space was a minimum but they flower far better year after year if left undisturbed.

Also....if you look at the GoYpedia page for Amarylis....there are full instructions on the care of these plants.
