Terms of planting

The timing of planting this crop depends on the method of cultivation and on the region. If you plant seeds for seedlings, the optimal time is from the end of March to the first decade of April, since Olina’s onion is early ripe.

Placed in warm water, then allowed to dry and kept in “Heteroauxin” or other growth stimulant. After that, it is wrapped in damp gauze, put in a saucer and kept for a week at room temperature.

Olina onion seedlings are grown in low boxes

Next, they act like this:

1. They take a pre-prepared soil mixture (two parts of soddy land and one part of black peat, humus and sand).
2. Previously, the earth is put in the freezer for several days or kept in the oven (15 minutes at 130 degrees).
3. The soil is laid in individual pots or common boxes up to 10 cm high. Cassettes can be used. At the same time, 3-4 seeds are sown in each cell.
4. Make grooves at a distance of 5 cm.
5. Spread the seeds of Olin’s onion 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 water. Withstand 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 transplanting, the containers are taken out onto the balcony or outside, hardened at a temperature of +10 ° C.
10. Transplanted into open ground closer to the beginning of May. Planting depth 2 cm, spacing 6 cm, distance between furrows 50 cm. At the time of transplantation, each seedling should have at least three full leaves. Previously, the roots of seedlings can be held in a growth stimulator solution.
11. During transplantation, leaves and root shoots should be shortened by a third of their length.

Planting sevka in the spring

1. Clean, dig and fertilize the soil in advance, for example, with compost or humus (5 kg per 1 m²).
2. Select the sevok – it should be moderately large (diameter up to 3 cm) and without rot, damage. Two weeks before planting, warm up for six hours at a temperature of 40 degrees, then pickle in a fungicide 0,5-1 hour.
3. Make several furrows at a distance of 25 cm.
4. Plant the seedlings to a depth of 1,5 cm with an interval of 5 cm (for large bulbs, a distance of 10 cm).

   

5. Sprinkle with fertile soil and water abundantly.
6. Lay sawdust, straw, needles or other mulch 3 cm high.

Olin’s onion care

When planting sevka, the first shoots appear after 10–15 days. To do this, it is necessary to ensure normal watering, top dressing and other conditions:

1. Water the onions as the surface layer of the soil dries out. In drought, water is given at least once a week. At the same time, a month before harvesting, watering is stopped, even if the heat is established.
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 they give superphosphate (20 g per 1 m²) and potassium salt (10 g per 1 m²), after another 21 days, the same composition is added.
3. After watering and rains, the soil should be loosened.
4. Weeding is done regularly to prevent weeds from sprouting. To facilitate the task, it is recommended to lay out a layer of mulch.
