- Warm the nigella for 20 minutes in hot water (temperature up to 50 °C).
- Immerse the seed in cold water for a minute.
- Treat the seeds with Epin or another growth stimulant, following the instructions for the drug.
For sowing nigella, purchased soil or a mixture of equal parts of turf soil and humus is suitable. For better looseness, add vermiculite or coconut fiber.
You can grow Bamberger seeds in wooden boxes, pots or opaque containers. The sowing algorithm is simple:
- Fill the containers with soil with a layer of 8 cm.
- Moisten the soil one day before.
- Make holes or grooves 1 cm deep, leaving 3 cm between rows.
- Sow seeds at 2 cm intervals.
- Cover the plantings with soil.
- Lightly compact the soil.
- Moisten the soil with a spray bottle.
- Make a shelter out of glass or film.
Until seedlings emerge, keep the seedlings warm (optimally 25 °C). Then the shelter is removed and good lighting is provided. Seedlings can be kept on a windowsill or in a greenhouse. Caring for it consists of the following activities:
- regular watering - maintain moderate humidity, use warm water;
- thinning - leave 2 cm between adjacent sprouts;
- fertilizing seven days after sowing, then after two weeks;
- pruning when two leaves appear at 1-2 cm to stimulate the development of the root system.
You can feed Bamberger onion seedlings with a solution of chicken manure (1:10) or the following composition:
- a bucket of water;
- 5 g potassium chloride;
- 10 g urea;
- 20 g superphosphate.
Bamberger seeds should be sown for seedlings approximately 50 days before moving to open ground
Seedlings are moved into open ground in the evening or on cloudy days after preliminary watering. The leaves are cut off by a third, the roots are shortened to 2.5 cm, treated with a mixture of clay and humus.
Planting seedlings in open ground in spring
For planting, you can use your own or purchased Bamberger sets. The raw materials must be dried to prevent spoilage. For 2-3 weeks before planting, it is kept in a warm place at 20 °C, then 24 hours at 35-40 °C. Another warming option is to immerse the bulbs in hot water for 20 minutes and treat them with a growth stimulator.
The Bamberger variety has good immunity, but it is better not to neglect prevention and treat the seedlings in a solution of potassium permanganate. Copper sulfate is also effective for disinfection.
The area for planting seedlings is prepared in the fall:
- digging;
- weed removal;
- burning of plant residues;
- adding organic matter, but not fresh manure.
For spring planting, take Bamberger seeds no smaller than 1 cm. Work procedure:
- Dig up the area and loosen it.
- Make holes, leaving 20-30 cm between rows.
- Plant the seedlings.
- Mulch the bed. You can use hay, straw, sawdust.
- If desired, lay covering material to speed up germination.
When planting sets, you can leave 10 cm between adjacent bulbs. This distance will increase due to the collection of greens.
Is it possible and how to plant Bamberger onions before winter?

- Remove weeds, level the area, compact the surface.
- Make grooves at a distance of 20 cm.
- Distribute the dry seedlings into the recesses at intervals of 6 cm.
