i bring mine in and put them in a clay pot with a very fast draining mix. bright sunny window. water when dry.

if you don't get any other responses here. then, there is an Amaryllis/Hippeastrum Forum on GW. they are very helpful with the care of your amaryllis.

You will need to bring it in for the winter. If maintained as has been suggested it will be ready to put back in your garden after the last frost. Here where the winter temperature is seldom below 25 degrees they are in the garden year around and bloom about the end of May. If your Hippeastrum does well during the summer about this time next year you may take the pot out of the ground lay it on its side and stop all water, forcing it into dormancy. Keep it in a cool dry place until about the first of December when it can be repotted in fresh potting mix watered and put into good light and growth and bloom should start in a few weeks. Al
