Remove the amaryllis bulb from its pot or from the ground. Cut away any dead foliage or cut back existing foliage to 3 inches tall, if needed.
Tease the roots loose, especially if growing in a circle on the bottom. Remove any dead or diseased roots. Remove as much soil from the roots as possible, either by hand or with a strong spray of water.
Use a pot deep enough for good root growth, with adequate drainage and at least 1 inch larger in diameter than the bulb.
Fill the pot one-third full of potting mix. Spread the amaryllis roots out and place in the pot. Add soil to bring the bulb up to the proper height.
Add 1 tbsp. blood and bone meal under the bulb to help it get started. Fill the pot with potting mix so that the neck of the amaryllis bulb is above the soil line. Tamp soil down and water well.

Dig a hole 1 inch wider in diameter than the bulb and deep enough so that the neck of the bulb is above the soil line.
Sprinkle 1 tbsp. of blood and bone meal into the bottom of the hole. Spread out the roots in the bottom of the hole and fill with removed soil.
Firm soil around bulb and water well. Add mulch, if desired, but do not cover the neck of the amaryllis bulb.
