One of the simplest ways to get a lot of bulbs without spending much money is by propogating the amaryllis flower to produce seeds. All it takes is a blooming flower and a little knowledge of the amaryllis blossom's anatomy, and within a few weeks, you will have seeds. These seeds can be collected and planted immediately to start the growth of new bulbs. Of course, it will take several growing seasons before the little bulbet will be big enough to blossom, but this method costs very little.
Inspect the amaryllis flower blossom to understand the different parts necessary for the pollination process. When the blossom has opened its petals wide, you will see several structures coming out from the center of the flower. The extra long one with a three-part end is the female part or the pistil. There should be about six other stems with a head of pollen on them. These are the stamens-- the male part of the flower.
Remove one of the stamens from the blossom. You can either use the stamen from the same blossom or from another blossom. This is when you can cross genetic material such as the color of the blossom. Rub the anther or the head of pollen against the middle of the stigma. The stigma should be wide open for pollination to be successful. Do this process with as many flowers as you like.
Watch the ovum or the thickened part just under the stigma. This should swell if the pollination was successful. Allow it to grow with the plant until the ovum actually splits and the seeds are accessible. The seeds will be black and papery. Only the ones with a lump in the middle are viable.
Plant these seeds immediately or shortly after they are released from the flower. Some people sprout them in a warm dish of water, but placing them in some warm moist soil will also work. Continue to grow these little bulbets that form for two or three more growing seasons until they are large enough to produce a blossom.
