Landing dates

The timing of planting this crop depends on the growing method and the region. If you plant seeds for seedlings, the optimal time is from the end of March to the first ten days of April, since Olin’s onions are early ripening. In this case, the seedlings are transferred to the ground in early May, i.e. approximately two months after germination. The seeds can also be planted in open ground - preferably at the end of April. Around the same time, the seedlings are planted.

Autumn planting is also allowed. To do this, use seedlings, which are planted:

from the end of October to the first ten days of November in Central Russia;
from the last days of September to mid-October in the Urals, Siberia, and the Far East.

To harvest a large harvest, Olin's onions are recommended to be planted just before winter. Otherwise, the performance will be low.

Methods for planting Olin's onions

Olin's onions can be grown in the following ways:

sowing seeds for seedlings or in the ground (annual crop);
sowing seeds in the garden (for two-year-old specimens).

The easiest way is to plant seedlings and get a harvest in July. The seedling method of growing Olin's onions is also allowed. It is more labor-intensive, but more economical in terms of costs.

Growing seedlings from seeds

At the first stage, Olin's onion seeds need to be prepared for planting. They are pickled in a weak solution of potassium permanganate for half an hour. Place in warm water, then allow to dry and incubate in Heteroauxin or other growth stimulant. After this, wrap it in damp gauze, place it in a saucer and keep it for a week at room temperature.

Olin onion seedlings are grown in low boxes

Then proceed like this:

Take a pre-prepared soil mixture (two parts of turf soil and one part each of black peat, humus and sand).
First, the soil is placed in the freezer for several days or kept in the oven (15 minutes at 130 degrees).
Place the soil 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.
Make grooves at a distance of 5 cm.
Place the Olin onion seeds with tweezers to a depth of 0.5–1 cm at intervals of 3 cm.
Sprinkle with soil and spray with a little water.
Cover the container with plastic wrap, periodically ventilate and water. They can withstand temperatures at +22–25 degrees.
When shoots appear, the film is removed. The temperature drops to +15–18 degrees.
Two weeks before transplantation, the containers are taken out onto the balcony or outside and hardened at a temperature of +10 °C.
They are transplanted into open ground closer to the beginning of May. Planting depth is 2 cm, interval is 6 cm, distance between furrows is 50 cm. At the time of transplantation, each seedling should have at least three full-fledged leaves. The roots of the seedlings can first be kept in a solution of a growth stimulator.
During transplantation, leaves and root shoots should be shortened by a third of their length.

Attention! When growing Olin onions, it is advisable to light the seedlings up to 14–15 hours a day. For this purpose, phytolamps are used.

Planting seedlings in spring

Olin onion sets are sown in the spring at the end of April (if the weather is warm and dry). The algorithm of actions is as follows:

Clean, dig and fertilize the soil in advance, for example, with compost or humus (5 kg per 1 m²).
Select the seedlings - they should be moderately large (diameter up to 3 cm) and without rot or damage. Two weeks before planting, warm up for six hours at a temperature of 40 degrees, then treat with fungicide for 0.5-1 hours.
Make several furrows at a distance of 25 cm.
Plant the sets to a depth of 1.5 cm with an interval of 5 cm (for large bulbs, a distance of 10 cm).
Sprinkle with fertile soil and water generously.
Lay sawdust, straw, pine needles or other mulch 3 cm high.

Advice! Small sets (up to 1 cm in diameter) are best used to produce bulbs. Large planting material is suitable for growing greenery.

Olina onion care

When planting seedlings, the first shoots appear within 10–15 days. To do this, it is necessary to ensure normal watering, fertilizing and other conditions:

Water the onions as the surface layer of soil dries out.During drought, water is given at least once a week. In this case, a month before harvesting, watering is stopped, even if it is hot.
Fertilizing 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.
After watering and rains, the soil should be loosened.
Weeding is done regularly to prevent weeds from sprouting. To make the task easier, it is recommended to lay out a layer of mulch.

Disease and pest control

Olin's onions are generally resistant to various diseases and pests, but can suffer from onion flies, and if overwatered, from root rot. Powdery mildew is also possible. The main preventive measures are:

moderate watering;
regular loosening of the soil and weeding;
inspection of crops and treatment with various means.

If a whitish coating, spots and other signs of planting are detected, the planting is treated with Bordeaux mixture or fungcides (HOM, Skor, Ordan, Fitosporin). To combat onion fly, folk remedies are used:

dusting with tobacco dust or wood ash;
spraying with a solution of laundry soap or salt;

For prevention, treatment with infusion of dandelion leaves is necessary.

If these measures do not help, use insecticides:

"Medvetox";
"Aktara";
"Zemlin";
"Fly-eater";
"Karate Zeon" and others.

Onion fly leads to complete destruction of leaves

Attention! Olin onions are processed in the late evening or early morning. It is advisable that there is no rain or strong wind in the forecast.

Reviews from gardeners about Olin's onions

Marina Gushchina, 54 years old, Yaroslavl

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

Andrey Sazonov, 46 years old, Odintsovo

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