  3. The soil is placed in individual pots or common boxes up to 10 cm high. You can use cassettes. In this case, 3-4 seeds are sown in each cell.
  4. Grooves are made at a distance of 5 cm.
  5. Spread Olin onion seeds with tweezers to a depth of 0.5-1 cm with an interval of 3 cm.
  6. Sprinkle with soil, spray a little with water.
  7. Cover the container with plastic wrap, periodically ventilate and watered. Maintain the temperature at the level of + 22-25 degrees.
  8. When shoots appear, the film is removed. The temperature is lowered to + 15-18 degrees.
  9. Two weeks before the transplant, the containers are taken out onto the balcony or outside, tempered at a temperature of +10 ° C.
  10. They are transplanted into open ground closer to the beginning of May. The planting depth is 2 cm, the spacing is 6 cm, the distance between the furrows is 50 cm. At the time of transplanting, each seedling should have at least three full-fledged leaves. Previously, the roots of the seedlings can be held in a solution of a growth stimulant.
  11. During transplantation, the leaves and root processes should be shortened by one third of their length.

  1. Clean, dig up and fertilize the soil in advance, for example, with compost or humus (5 kg per 1 m2).
  2. Select sevok - it should be moderately large (up to 3 cm in diameter) and without rot, damage. Two weeks before planting, warm up for six hours at a temperature of 40 degrees, then pickle in a fungicide for 0.5-1 hours.
  3. Make several furrows at a distance of 25 cm.

  2. Top dressing is applied three times per season - after the appearance of green feathers, urea is given (20 g per 1 m2), after three weeks superphosphate is given (20 g per 1 m2) and potassium salt (10 g per 1 m2), after another 21 days, the same composition is introduced.
  3. After watering and rains, the soil should be loosened.
  4. Weeding is done regularly to prevent weeds from germinating. To make the task easier, it is recommended to lay out a layer of mulch.

Reviews of gardeners about Olin onions

Marina Gushchina, 54 years old, Yaroslavl

Olin is a Czech variety, but the seeds are inexpensive, as are the Russian varieties. I liked it because it ripens no longer than three months. I grow seedlings as an annual, harvest in mid-July. In general, the culture is winter - you can sow it in October, then the bulbs will be larger and the greenery will be more luxuriant.

Andrey Sazonov, 46 years old, Odintsovo

Olin's onion is winter, I plant it at the end of October and then take care of it all season. But friends are also grown as an annual - from seedlings. It tastes very pleasant, not as pungent as our varieties. Most often I add to salads.
