Landing dates
Having chosen the optimal planting time, you can grow an excellent Sturon onion without unnecessary trouble. The description of this variety suggests an early start of planting work. As soon as the soil thaws 5–6 centimeters, sowing begins. In the southern regions, this time falls on the end of March, in the rest - the beginning or mid-April.
Seed planting rules
Preparation of the site for planting onions begins with digging up the soil and applying compost. One square meter will require half a bucket of fertilizer. Wood ash and phosphorus fertilizers are also added. In the spring, a couple of days before the planting of Sturon, the site is plowed up and the beds are marked. After that, the soil is compacted and covered with a black film so that it warms up well.
Before sowing, the seeds are soaked for a couple of hours in a solution of potassium permanganate or aloe juice. Then they are placed in a moistened piece of cloth for 2 days. Before sowing, the beds are abundantly watered and grooved. The distance between the rows of the Sturon bow is 10 cm.
Basic care
Sturon onions are undemanding to care for, but some attention should be paid to them. To obtain a large seeding, the seedlings are thinned out after the emergence of shoots. The soil needs constant loosening, which helps to mix fertilizers and remove weeds. Watering is carried out only occasionally, when the topsoil is very dry.
As soon as the greens of the Sturon onion wither, they stop carrying out all types of work in the beds and wait for the plant to wither and the neck becomes soft. During this period, they begin to harvest their crops. Cleaning time is usually mid to late summer.
Growing two-year-old onions
It was said above that Sturon is grown as a two-year-old. To do this, a few weeks before the onset of frost, a set is taken and planted on previously prepared beds. The variety is not afraid of frost, therefore, with the beginning of the first thaws, the onions will gain strength, and the heads will grow.
Sturon is also planted with the arrival of spring. From autumn, organic fertilizers are applied to the proposed planting site, and mineral fertilizers are applied immediately before planting. The heads are buried by 2-3 centimeters, leaving 2 centimeters of soil above their shoulders. The distance between the bulbs is 9-12 centimeters.
Under no circumstances should Sturon be fertilized with chemicals containing nitrogen. The fact is that onions tend to accumulate nitrates in themselves, therefore, subsequently, they cause great harm to the human body.
The Sturon variety has proven itself well and continues to gain popularity among domestic farmers due to its unpretentiousness and resistance to diseases.
