i bought an Amaryllis plant from Home Depot a few year back and it is still flowering biannually. It was getting crowded in the original pot adn I decided to break it up into a few new containers. I bought some regular potting soil, large clay pots. I began by turning the original pot containing the Amaryllis bulbs upside down over some newspaper and gently removing and separating the bulbs. I then partially filled the new pots with soil, made an indentation in the midle of the pot and set one or two bulbs in each pot adding soil but not completely covering the bulb’s crown where new growth occurs. I watered the pots which were in aluminum pans and left outside in rainy weather before bringing them inside the house. Once green shoots appear, start watering again!
2012 season: All repotted bulbs are growing and have been placed outdoors for the warm summer months.

It’s been a year since I repotted my Amaryllis, and during the summer months all the bulbs sprouted leaves but no blooms. Some of the bulbs which did not sprout leaves during the preceding Winter, sprouted outdoors in the Summer. I had believed that these bulbs were dead, but they surprised me! I brought the Amaryllis plants back in the house near an eastely facing window for the winter in late September. The summer growth seems to be wilting. They are now on limited water for the winter till the summer growth browns and new green sprouts.
