  • high cost of sevka.

Planting methods for Corrado onions

A high yield can only be harvested from quality material. To get a turnip of Corrado onions in the Southern regions and the Middle lane in one season, you can use podwinter or early spring sowing, as well as seedlings.

In colder regions, the seed is first obtained from the seed. Only the next season is the turnip harvested.

Growing from seeds

Seeds are sown at the end of April in open ground (in regions with a warm climate). They are pre-soaked in warm water or in a growth stimulator for 1-2 days.

The most commonly used tape landing method. 20 cm between the ribbons. Planting depth - 1-2 cm. After the emergence of seedlings, the beds are thinned out, maintaining an interval of 2 cm between adjacent specimens. When the onion has three true leaves, the procedure is repeated. There should be a distance of 6 cm between adjacent plants.

If the seeds are planted before winter, then the best period is late October - early November. In this case, the seeding rate is increased threefold. Landings must be mulched with a thick layer of peat. This method is good because the seedlings appear much earlier, therefore, the bulbs ripen faster.

To get seedlings, Corrado seeds are sown in a container in a heated room in early March.

The seedlings are transferred to the open ground after 50-60 days. By this time, the seedlings should have 3-4 true leaves. The transplant is carried out on a cloudy day. A distance of 25 cm is maintained between rows, and 6-8 cm between adjacent shoots.

Planting seedlings in open ground

In open ground, Corrado sevoks are planted after the threat of frost has passed. Shallow furrows are formed on the bed. There should be at least 20 cm between them. The soil is thoroughly watered, wood ash mixed with sand is added.

The sevok is buried in the ground and sprinkled so that there is a layer of 2 cm on top.

When planted shallowly, the Corrado onion gives early shoots, but in this case it will not be possible to grow a large turnip

6-8 cm are left between adjacent bulbs. This distance is necessary for the full-fledged formation of a turnip. Some gardeners in small beds use a serpentine planting. In this case, the Corrado sevoks are placed more densely. This type of cultivation requires thinning. When shoots appear, every second onion is pulled from the garden along with the feather. This method allows you to collect greens and grow a large turnip.

Corrado onion care

The yield of the crop directly depends on proper care.

Corrado onion needs timely watering

Humidification frequency depends on weather conditions. Usually, one watering per week is enough for a crop. In severe drought and no rain, the beds are moistened 2-3 times.

Attention! Watering is stopped two weeks before the planned harvest.

The introduction of dressings allows you to increase the yield of the Corrado variety. The procedure is carried out three times per season. To grow greens, nitrogen compounds are needed. They are used two weeks after the first shoots of the Corrado onion appear. A month later, nitrophoska is suitable as a top dressing. During the formation of the bulbs, it is recommended to use superphosphate, ash.


Corrado onion is a hybrid that is used for growing on a turnip and on a feather. The variety is fruitful, resistant to major diseases and pests of the crop. The long shelf life allows the onion to be used throughout the winter.

Reviews of gardeners about onion Corrado

Vyacheslav Georgievich, 53 years old, Stavropol Territory

I grow Corrado onions in the country. Greens are for sale, and I harvest turnips for the winter. Onions of this variety practically do not get sick, they are not affected by pests. With timely watering and fertilization, it is possible to collect a good harvest. The main thing is to find a good supplier of sevka.

Albina Nikolaevna, 49 years old, Millerovo

Corrado planted a bow a few years ago. Crop care is standard and yields are high. I plant the seed with a thickened planting, and in the process of collecting the greens, I thin out. This method is pleasant because it is possible to get both a feather and a turnip from one garden bed.

Konstantin Nikolaevich, 38 years old, Taganrog

I am engaged in the cultivation of Corrado onions for sale. The variety is high-yielding, it is stored for a long time, so I consider it a profitable business. There is no end to buyers. I allocate a small area for greenery. She also sells well in the spring. I plant the rest of the beds under the turnip. Caring for Corrado onions is standard: watering, feeding, thinning.
