This will slightly weaken the bulb, so be sure to fertilize well afterwards. Sow the seeds soon after harvesting. In about four weeks the seedlings should be up and growing. When the second set of leaves forms, move them to an individual three inch pot. Keep them in a sunny location, and don't allow the leaves to die down for the first year.
Seedlings normally can take up to three to five years to produce their first bloom.
Many people would like to plant their bulbs outdoors for year-round growth. Although, some people have had success with this by mulching the plants heavily, it is preferable to bring them indoors each year. Besides the chance of losing the bulb to a hard winter, you need the color and enjoyment of these flowers indoors during the winter months more than you need it in the garden in the summer. There is a variety of amaryllis that is hardy and will come back each year in the garden. Compared to the cost of other bulbs, amaryllis bulbs seem to be somewhat pricey.
