Most of the time, Amaryllis is frequently multiplied by bulb separation, as it follows: around the mother bulb, which is the biggest bulb in the pot, will appear small bulbs. Those small bulbs should not be separated by the mother bulb until they have grown enough and have their own roots.
Once they have developed enough, then you can detach them of the mother bulb. This procedure is done only when the plant gets into the rest period, after the flowers dried and fallen. This time is around autumn, when you start watering the plant less often.
Over winter, the mother bulb and the small bulbs are stratified. You must keep them in dark and cool places to get over the cold period the plant needs to grow.
The small bulbs are treated at this time just like the mother bulb. This means that in the spring it will be planted separately, in the ground. It will be watered and cared for until the fall. In the first 2-3 years the bulb will focus only on the nutrients it needs to its development. It will grow in diameter and will become bigger and bigger.
During this time, Amaryllis will make the leaves, but not the floral stem. Only when it reaches maturity, after 2-3 years, the bulb will bloom. The floral stem will appear in the spring, before the leaves.
A second way to multiply Amaryllis is through seeds. These occur only if the plant has been pollinated artificially by man or bee. Germination is not difficult, but you have to keep in mind that plants obtained from seeds are able to flourish after 4-5 years. Once they appear, plants need to provide the necessary temperature and light conditions, just like a mature plant that makes flowers. Phase fertilization is done monthly with complex fertilizers. Choose fertilizers with a higher content of Phosphorus (P) and Potassium (K) to the detriment of Nitrogen (N).
