Characteristics and description of appearance
The height of the plant does not exceed 35 cm. The bulbs are quite large and dense, pinkish-white in color .
The taste of such onions is slightly spicy, although other varieties of yellow onions, on the contrary, are very spicy. The weight of the onion is approximately 120 grams.
Size – from 8 cm. From one square meter you can collect approximately 3 kg of bulbs. Rosanna onions produce a large harvest and are stored for a long time (throughout the winter).
When to plant pink Rossana?
The end of April - the beginning of May is the most ideal time for planting Rosanna onions . The soil is moist and the air temperature is not higher than 15 degrees. If you start planting a little earlier, the onions will begin to shoot and deteriorate.
Moreover, experienced farmers also pay attention to various folk signs, for example, it is necessary to plant onions after the bird cherry blossoms. If on the 20th of the month the bird cherry tree has not even thought of blooming, it is better to refrain from sowing for now.
Preparing the beds and soil
- Before planting, the onions themselves need to be sorted and sorted.
- Then the bulbs are warmed up quite a bit, for example, kept in a warm place, or doused with water. This is necessary so that the bow does not start shooting arrows soon.
- Next it is dried.
Preparing the beds in advance is also an important step . The soil is loosened and cleared of weeds and other debris.
- If the soil at the planting site is very loamy, add a nutrient to it - 5 kg of humus, 5 kg of peat, 4 tablespoons of superphosphate, 1 teaspoon of urea. This amount of solution is enough for 1 square meter of territory.
- If the soil is sandy, then it is treated with a mixture containing: 1 bucket of peat and humus, 2 tablespoons of superphosphate, 1 tablespoon of urea.
The beds are furrowed, taking into account a distance of 18-20 cm. The holes should be located 10 cm from each other. Its depth is up to 5 cm.
Planting and sowing
For a better harvest, it is recommended to grow onion sets yourself from seeds (seeder). First, you need to choose the right place for sowing “chernushka”. The most favorable are considered to be beds where potatoes, tomatoes, cucumbers or cabbage previously grew. It is these predecessors that save different types of onions from vitamin deficiency.
- In order to reduce the risk of damage to the seedlings by pests, you should not plant them in the same place for several years. The earth needs rest.
- The place for sowing the seedlings should be chosen on the sunny side, where the beds will receive a sufficient amount of light. The soil at the planting site must be fertile, otherwise the feather will germinate poorly.
- The soil must be properly prepared before planting: cleared of weeds and dug up. Before this, during the fall, the soil should be fertilized with potassium and phosphorus fertilizers, compost and rotted manure. It is strictly not recommended to use fresh manure, because when it is used as fertilizer in the second half of plant growth, the growth of feathers, rather than the bulb, is enhanced. If the soil that was chosen for planting is highly acidic, it must be treated with lime.
- The right time for sowing is at the end of April and the first days of March.
- After the cold weather subsides, the seeds should be prepared for planting. To do this, they need to be soaked in a damp cloth or water for a day (24 hours) or until the first shoots appear. This promotes better germination. After soaking, the seeds should be dried in a shady place. Finally, there must be seed treatment with agents against diseases and pests (neck rot and onion fly).
- Make shallow grooves (up to 2 cm) in the dug up soil and water them. It is important to maintain the correct distance between rows of seeds (from 8 to 13 cm). Seeds must be placed at a distance of 5 mm to 2 cm.
- It is necessary to properly care for the crop: fertilize it and water it in the first half of growth. If the soil where the sowing was done is fertile, additional fertilizing is not required. A month before harvest, watering must be stopped.
- After harvesting, it is important to sort the bulbs by size (sorting is an important process) and hang them in a nylon in a warm (18 to 22°C) and dry room.
Growing onions from sets does not require special skills, everything is within the limits of primitive knowledge about the garden. Next season, the already prepared planting material must be planted in the ground. You can skip the first stage and buy ready-made onion sets, but preparing planting material yourself is always of much better quality and gives a larger harvest in the end.
Ready-made onion sets (planters) are sown in spring or autumn. The stages of planting and caring for plants are not too different from the care of sowing described above.
Growing from sets
Some farmers plant this variety traditionally by placing the seeds in the soil. However, when growing seedlings, the harvest will be more abundant. If onions are planted as seeds, onion sets are harvested in the fall and planted as seedlings the following year.
Preparing onion sets
- One or two weeks before planting onions, the bed is doused with a solution of copper sulfate or phytosporin (1 tablespoon per 10 liters of water).
- Then the onions are carefully sorted and heated.
- Bulbs should be stored at a temperature of 10 degrees for 3 weeks before planting. 6-7 hours before, the temperature increases to 35 degrees.
- Immediately before planting, the bulbs are treated with a growth stimulator or a one percent solution of copper sulfate.
Landing
In the onion beds, special grooves are made in which the bulbs are planted . The depth of the grooves should not exceed 5 cm, and the distance between adjacent holes should be 8 cm. The rows should not be closer than 25 cm to each other.
Rules of care
If you follow all the rules for caring for the variety, it will produce a large harvest and will live for an extremely long time. Timely weeding, getting rid of pests, controlling soil moisture and temperature - all this should be under the control of the farmer.
Watering
Watering the bulbs is carried out once every 10 days . The method is used drip or inter-row. With any other method, water gets between the feathers of the onion, which begins to rot. About a month before the start of harvesting, it is recommended to completely cancel watering.
Top dressing
In order for the onion to grow actively, it is fed. It is done as follows:
- 1 glass of bird droppings;
- 1 tablespoon of urea;
- 10 liters of clean water.
The beds are watered with 3 liters per square meter.
After two weeks, the procedure is repeated:
- 2 tablespoons “Nitrophoska”;
- 10 liters of clean water.
Watering occurs at the rate of 5 liters of the drug per square kilometer.
Thermal and light conditions
Rosanna onions love loose, nutritious soil with a neutral reaction . This variety is completely unpretentious to any special light regime, but better and higher-quality development occurs in illuminated places.
Circumcision - is it necessary?
To ensure that the onion feathers are even and grow quickly and abundantly, the plant is pruned.
Some farmers do this along the neck line, and some cut off the top of the bulb. There is no particular difference between these two methods.
It is best to do pruning before planting , but the procedure cannot be carried out too early. You can trim the bulb with either a knife or pruning shears. It all depends on the size of the vegetable.
Description of the Rossana variety
The bulbs of this variety have a pleasant sweet-spicy taste and are suitable for fresh consumption. Due to the preservation of beneficial properties after heat treatment, Rossana is often used as an additive to dishes that require boiling, frying or stewing. Onions are also suitable for drying, salting and pickling.

Diseases and pests
Parasites can attack Rosanna onions, which will negatively affect the harvest or even kill the plant.
- Powdery mildew . The bulbs change, do not develop and die. An unpleasant white coating appears on the plant. In order to cure the plant, it is treated with fungicides or potassium-phosphorus preparations.
- Cervical rot . The bulb becomes soft and slimy. The shell turns brown and a gray coating appears on top of it. As a medicine, a solution of wood ash is used (1 glass of ash and chalk + 11 teaspoons of copper sulfate + 10 liters of clean water), which is sprayed over 3 square meters of territory.
- Jaundice . The bulb turns yellow, large yellow dots appear on the arrows. It is impossible to cure the plant from this disease. Affected fruits are thrown away.
- Onion fly . The insect leaves larvae inside the bulbs, from which small flies hatch and eat the vegetable from the inside. To get rid of the pest, use a saline solution (10 liters of clean water + 300 g of salt). The spraying procedure is carried out every ten days.
- Root mites . To get rid of these pests, the plant is treated with a 0.2% Keltan solution.
When to collect?
The best time to harvest Rosanna onions is in late July - early August. More often, farmers focus on the appearance of the bulbs; for example, if a little less than half of the bed bends down to the ground, then it’s time to start harvesting.
Important! Farmers often speed up the ripening process of onions in order to be in time for the rainy season. To speed it up, a month before the start of harvesting, the bulbs are cleared of the soil. This way they dry out a little. The cleaning itself is carried out only in dry, sunny weather.
After harvesting the onion, it is dried. This is done in dry basements that have a good ventilation system. Leave the onions there for 2 weeks at a temperature of 28 to 40 degrees. On warm days, it is better to take vegetables outside. The sun's rays allow the bulbs to dry twice as fast . Moreover, they destroy diseases that may be present in the fruits.
All types of onions differ in ripening time, shape, color and taste, as well as shelf life. We suggest comparing the following varieties: Shakespeare, Hercules, Carmen, Red Baron, Sturon, Exhibition, Bessonovsky, Anzur, Parade and Snowball.
Advantages and disadvantages
Any vegetable has both advantages and disadvantages. Russian gardeners speak positively about the crop.
The main advantage of Rosanna onions is their long shelf life.
Advantages:
- unpretentiousness to soil composition;
- high productivity;
- resistance to illnesses.
The disadvantages include the heat-loving nature of the variety. A sharp drop in temperature causes the turnip to stop growing and may die.
How to store?
After harvesting, the onions are carefully selected. The smallest bulbs go into storage for planting next year, while the larger ones wait to be used in a dish.
Bulbs should be stored in a dark, dry room that has good, constant ventilation. Medium-sized bulbs are braided, and larger fruits are placed in boxes or boxes with small holes for ventilation. The room temperature does not exceed 20 degrees.
Don't forget to regularly inspect your crop. Sprouted onions are not suitable for eating . It germinates more often if it is not properly prepared before planting, that is, it is not completely dried.
Rosanna onion is a very unpretentious and tasty variety of onion. If you follow all the rules for growing it and take care of it, you can get a bountiful and good harvest. Buy only high-quality seedlings or seeds, do not forget to thoroughly prepare the soil, monitor the time of planting and harvesting, fertilize the soil and regularly inspect the onions.
Reviews about the Rossana onion variety
Reviews from gardeners about the Rossana variety are positive:
Yuri, Kaliningrad: “I am a gardener with great experience and have tried to grow many varieties of onions. I definitely have something to compare Rossan with, so I confidently say that this is my favorite variety. The yield is excellent even in not entirely favorable weather conditions, the taste of onions is moderately pungent and they are stored all winter.”
Irina, Volzhsk: “I’ve been planting Rossana for five years now, and I don’t plan to change it to another variety. In the first year I grew seedlings from seeds, but then I started buying ready-made seedlings - it’s faster and easier. They say that the yield decreases if you grow onions from sets, but I didn’t notice this. If it decreased, it was only slightly. I love this variety for its not too pungent taste, beautiful appearance and long shelf life.”
