The Allium Schubertii, also known as Schubert's leek, is an ornamental onion with striking, light purple flowers. When propagating, you can use either the generative or vegetative method. You can find out how this works and what you need to pay attention to here.
How to propagate Allium Schubertii?
Allium Schubertii, the Schubert's leek, can be propagated by sowing seeds or propagating daughter bulbs. The seeds are ready to harvest in autumn and should be stored in a cool place. Daughter bulbs can be planted from September to November.
How can I propagate Allium Schubertii?
The ornamental onion can be propagated by sowingseeds as well as by onions. The former is referred to as generative propagation and the latter as vegetative propagation. Both methods have their advantages and disadvantages.
Where do you get Allium Schubertii seeds?
The seeds of the Allium Schubertii can either be bought inspecialist storesorgathered yourself. If you already have an Allium Schubertii in the garden, you can observe the seed formation on your own plant: Do not cut off the spent flowers, but let them dry on the plant. Capsule fruits containing the small seeds then form on the dried flowers. You can tell when the seeds are ripe because the seeds are black and shiny and can be easily shaken out of the capsules.
When is the best time to harvest Allium Schubertii seeds?
InAutumn the flowers of the ornamental onion have dried up and the capsule fruits have formed the seeds. The best time to harvest seeds is between September and November.
How are the seeds of Allium Schubertii sown?
You can either sow the seedsimmediately after harvestor store them until a later dateIn both cases you should note that Ornamental garlic is a cold germinator. They need a cold stimulus to begin germination. With direct sowing, you sow the seeds directly after harvesting the seeds:
- Draw seed grooves 1 cm deep.
- Place the seeds ten centimeters apart.
- Cover the grooves with soil and press them lightly.
- Water the seeds with a soft stream of water.
- Cover the seeds with a net (€33.00 on Amazon) to prevent them from being eaten by birds.
When sowing, pay attention to a sunny location and loose, sandy and nutrient-rich soil. The ornamental garlic seeds will begin to germinate in spring.
If you do not want to sow the seeds directly, you should store them in a cool, dry and dark place.
How does the vegetative propagation of Allium Schubertii work?
During vegetative propagation, thedaughter onions of the Allium Schubertii are dug up in autumn and separated from the mother onion. This is the simplest method for propagating ornamental garlic, which, in contrast to propagation using seeds, is always successful. The daughter bulbs can be planted from September to November so that they have enough time to develop their first roots before winter. The method is particularly suitable if your ornamental onion grows too densely in one area of the garden.
Tip
Ornamental onions sow themselves
If the site conditions are right and the flowers are not cut off prematurely, ornamental onions can sow themselves.
