When the amaryllis has bloomed in spring and forms seed capsules, you can harvest them and propagate the plant.
A guide from pollination to germination.
The amaryllis, also known as the knight's star, fascinates with its magnificent flowers and its easy care.
But what do you do when the flowering period is over in March?
Propagation from seeds is an exciting way to grow new plants and nurture them into flowering specimens.
Even though growing it is easy, you should have some patience for the first flowering.
Leave nothing to chance: pollinating amaryllis is easy
Many amaryllis plants are self-pollinating and do not require external pollinators - but you can help with a brush.

Once the amaryllis has finished flowering, seed pods will sometimes form if you do not cut off the spent flower.
This also applies to cut flowers.
The capsules are initially green and develop after successful pollination during the flowering period.
Allow the seed pods to fully mature by continuing to care for the plant in a sunny location.
To ensure that fertile seeds develop reliably, you can also pollinate the flower yourself in advance.
This can be done by shaking the flower or transferring pollen to the pistil with a brush or cotton swab.
After five to eight weeks, the ovaries are swollen and the seeds are ripe.
Once the seed pods are dry and slightly brown, almost opening on their own and showing their black seeds, you can open the pods and remove the seeds.
It is advisable to sow the seeds immediately after collection to maintain their germination.
Offspring differ from the original plant
Amaryllis plants grown from self-harvested seeds do not necessarily correspond to the parent plant.
They can produce unexpected colors and flower shapes because amaryllis hybrids often have different characteristics.
Sowing and germination
The best time to sow amaryllis seeds is also in spring.
To do this, proceed as follows:

Use normal potting or growing soil.
Place the seeds on the surface and press them lightly.
Cover the seeds with a very thin layer of sand or soil.
Keep the soil moist but not wet, cover the container with cling film or a hood and place it in a warm and sunny place.
Amaryllis seed germination can take up to a month.
Until then, continue to keep the soil evenly moist and air the seeds regularly.
Once the seedlings are a few centimeters tall, you should carefully separate them and repot them into larger pots to encourage their growth.
After the Ice Saints, the plants can be placed on the balcony or terrace.
After about two more years, after further phases of fertilizing, overwintering and repotting, with a bit of luck the bulbs will be large enough to bloom for the first time in December.
But sometimes this takes five years.
If the propagation of the amaryllis takes too long for you, you can simply repot the plants after the flowering period, provide them with fresh soil and even continue cultivating them outside from mid-May.
It then blooms again in winter.
