Features of planting and growing

The seeds of this onion can be sown directly in open ground, but the seedling method will significantly increase the yield. It is important to provide the onion with proper conditions, otherwise it will lose its positive qualities.

Preparing for landing

To accelerate seed germination and strengthen the immunity of future plants, preliminary preparation of planting material is carried out.

About a week before sowing, the seeds are placed in a solution of potassium permanganate (0.1 g per 1 liter of water) and left in it for a day at a temperature of +20 .. + 25 ° C. After that, the swollen seeds are laid out between two layers of damp cloth. After 2-3 days, sprouts will appear, after which the seeds are slightly dried and sown in prepared containers.

The site for planting future seedlings is prepared in advance: weeds and plant residues are removed, the soil is loosened and applied to each square. m. 5 kg of peat, 4 kg of humus, 1 tbsp. l. superphosphate and 1 tsp. urea.

The Rossana variety is not picky about the soil composition and grows well in any soil.

Timing, scheme and landing rules

Seeds for seedlings are sown in late February or early March, following the following scheme:

1. Warm up the soil mixture to room temperature in advance and pour it into prepared containers.
2. Make holes in the soil at a distance of 3-4 cm from each other.
3. Place 2-3 seeds in each hole, deepening them by a maximum of 2 cm.
4. Sprinkle the crops with earth, tamp it lightly and water.
5. Cover the containers with polyethylene and put them in a room where the air temperature is at least + 20 ° C.

The improvised greenhouse is checked and aired daily, and after the first shoots appear, the polyethylene is removed.

Seedlings are transplanted into open ground in spring, when the average daily temperature is at least + 10 ° C, and the soil is still moist.

Reference. At the time of transplantation, the seedlings should be 35-40 days old, they should grow up to 10 cm, have a developed root system and several leaves.

Transplant process:

1. Two days before disembarkation, warm up the seedlings by placing them in a room with a higher air temperature.
2. On the site, prepare beds with a row spacing of 20 cm.
3. Make indentations in them every 10 cm.
4. Place seedlings in them, deepening by 3-5 cm.

Growing features

For the seeds to germinate, it is enough that the air temperature is + 4 ... + 5 ° C, a comfortable temperature for further growth and development of onions is + 12 ... + 14 ° C.

The Rossana variety loves light, so the site should be well lit.

It is better to plant onions on a hill. This variety tolerates drought well, but is sensitive to high humidity, so in the lowlands where water accumulates, there is a high risk of plant rot.

Onions cannot be planted for two years in a row in the same place, and the best predecessors of the variety are zucchini, cucumbers, cabbage, tomatoes, potatoes.

The nuances of care

For a high-quality harvest, plants are provided with proper care.

Onions watered every 10 days, using drip irrigation or pouring water into the aisles. When using the sprinkling method, water is retained between the leaves, which leads to decay of the heads, and watering under the bulbs prematurely exposes them from the ground.

Watering is stopped 14-20 days before harvesting.

The soil around the onion is loosened thoroughly after each watering or rain to prevent crusting on the surface of the soil and improve its aeration.

Also, the soil is regularly weeded, removing weeds from it, which takes nutrients from the soil, prevents air from reaching the underground part of the plants and shades the plantings, provoking increased humidity.

Fertilizers stimulate plant growth. Plants are fed twice with different compositions:

• in 10 liters of water dilute 1 tbsp. bird droppings and 1 tbsp. l. urea, the resulting solution is poured over the beds, the consumption is 3 liters of fertilizer per 1 sq. m;
• after 14 days, re-feeding is carried out - 2 tbsp. l. nitrophosphate is diluted in 10 liters of water and the plants are watered at the rate of 5 liters per 1 sq. m.

Disease and pest control

In case of violation of agrotechnical requirements, Rossana can be hit by:

• powdery mildew or downy mildew - potassium-phosphorus fertilizers are introduced into the soil, which enhance the immunity of the onion and treat the plants with fungicides;
• gray rot - carry out treatment with fungicidal preparations or a solution of wood ash (1 tbsp. Wood ash and chalk and 11 tsp. Copper sulfate per 10 liters of water, consumption - a bucket for 3 sq. M.);
• jaundice - the disease does not respond to treatment, the infected plants are removed.

Of pests onion flies and root mites are dangerous for the variety. To get rid of them, plants are treated with insecticides and acaricides, or carrots are planted nearby, which scares the onion fly.

Harvesting and storage

Term harvest storage depends on how correctly and timely it was assembled.

How and when to collect

Ripe bulbs are harvested in late July or early August, in dry and sunny weather, by pulling them out of the ground.

Reference. They start collecting as soon as the feathers on a quarter of the garden begin to bend to the ground and dry.

Storage features and keeping quality of the variety

The collected bulbs are examined and sorted out: the damaged specimens are thrown away or put aside for early use. Whole and high-quality heads dry well, cut off tops and long roots from them, cleaned of dirt and put them in cardboard boxes or wooden boxes.

Store onions in a dry, dark and well-ventilated room at a temperature of + 15 ... + 20 ° C.

Keeping quality of the variety - 65-75%, yield without loss of taste and quality kept for about eight months.

What can be the difficulties in growing

When cultivating the Rossana variety, some problems may arise:

• yellowing of young feathers is the result of a lack of nutrients in the soil;
• rotting of the bulbs indicates excessive watering;
• premature exposure of the bulbs occurs with improper watering.

Tips from experienced gardeners

Experienced vegetable growers recommend:

1. To ensure that the bulbs are exactly ripe before the rains begin, bend the feathers to the ground in August, and expose the bulbs from the soil 2-3 weeks before harvesting.
2. When planting, be guided by folk signs - the optimal time comes after the flowering of the bird cherry.
