I am trying a Amaryllis Belladonna this year also. I going to grow mine a pot but not to big, one just big enough so its nice and snug, the top of the bulbs needs to be above the surface. They like lots of drainage and to be baked, I think constricting the roots can help improve flowering.
I probably sink the pot into a border where I want it to flower, and lift before winter.
