Methods for planting Corrado onions
A high harvest can only be achieved from high-quality material. To get Corrado onion turnips in the Southern regions and the Central zone in one season, you can use winter or early spring sowing, as well as seedlings.
In colder regions, sets are first obtained from seeds. Only for the next season they collect turnips.
Growing from seeds
Seeds are sown at the end of April in open ground (in regions with warm climates). They are pre-soaked in warm water or in a growth stimulator for 1-2 days.
The most commonly used method is the tape planting method. The distance between the tapes is 20 cm. The planting depth is 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 neighboring plants.
If seeds are planted before winter, then the best period is late October - early November. In this case, the seeding rate is increased three times. Plantings must be mulched with a thick layer of peat.This method is good because shoots appear much earlier, so the bulbs ripen faster.
To obtain seedlings, Corrado seeds are sown in containers in a heated room in early March
Seedlings are transferred to 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
Corrado sets are planted in open ground after the threat of frost has passed. Shallow furrows are formed in the garden bed. There should be at least 20 cm between them. Water the soil thoroughly and add wood ash mixed with sand.
The sets are buried in the ground and sprinkled so that there is a 2 cm layer on top.
When planted shallowly, Corrado onions sprout early, but in this case it will not be possible to grow a large turnip
Leave 6-8 cm between adjacent bulbs. This distance is necessary for the full formation of the turnip. Some gardeners use snake planting in small beds. In this case, the Corrado set is placed more densely. This type of cultivation requires thinning. When shoots appear, every second bulb is pulled out from the garden bed along with the feather. This method allows you to collect greens and grow large turnips.
Corrado onion care
The crop yield directly depends on proper care.
Corrado onions need timely watering
The frequency of wetting depends on weather conditions. Typically, one watering per week is sufficient for the crop. In case of severe drought and lack of rain, the beds are moistened 2-3 times.
Fertilizing allows you to increase the yield of the Corrado variety.The procedure is carried out three times per season. To grow greenery, nitrogen compounds are needed. They are used two weeks after the first shoots of Corrado onions appear. After a month, nitrophoska will be suitable as a top dressing. During the formation of bulbs, it is recommended to use superphosphate and ash.
Conclusion
Corrado onion is a hybrid that is used for growing turnips and feathers. The variety is productive, resistant to major diseases and pests. The long shelf life allows you to use onions all winter.
