- The berries ripen in the shape of a cone, the top of which is bifurcated. Because of this feature, Roxanne fruits are often compared to "unopened tulip".
- Fruits are glossy, smooth with pronounced superficial yellow seeds.
- The bush is vigorous, compact, leafiness is medium.
- Productivity - up to 1.5 kg of berries per bush per season.
- Excellent transportability of ripe fruits.
- The universal purpose of the variety.
- Strong immunity.
The variety tolerates winters without shelter at temperatures not lower than -20 C, therefore, in central Russia, it is recommended to close strawberry plantations for the winter with a covering material.
Advantages and disadvantages of strawberries
The Italian variety of aromatic strawberries fell in love with Russian gardeners for the piquant shape of the fruit, yield and excellent transportability of ripe berries. The main advantages of the variety include:
- Genetic resistance to powdery mildew.
- Taste qualities: balanced sweet and sour taste with a slight bitterness and a pronounced aroma.
- Amicable ripening of fruits.
- Transportability and keeping quality of fruits.
- Suitable for commercial cultivation.
- Member of the berry conveyor: when the early varieties finish bearing fruit, Roxana pleases gardeners with the first harvest.
An amazing feature of the variety is the ability of ripe fruits to hang on the bushes for a week without losing the elasticity of the berries and deteriorating the taste.
There are practically no disadvantages of the variety. Negative characteristics include:
- Demanding to watering and applying mineral fertilizers.
- Cannot stand temperatures above +35 C.
- Average winter hardiness, additional shelters are required for the winter.
Note: The main disadvantage of the variety is the lodging of the peduncles on the ground during the ripening of the fruits, the berries become vulnerable to fungal diseases. It is recommended to cover the bushes with sawdust or straw mulch, or to plant the plants on an agrotechnical fabric.
Large berries ripen in the first harvest. In subsequent years, the berries become smaller, plantings are recommended to be renewed.
Dates and rules for disembarkation
Planting of seedlings in the soil of strawberries of the Italian variety Roxana can be carried out both in spring and in autumn. The best time to create a good root system is August.
The holes are made shallow, 20-25 cm is enough. A mixture of organic fertilizers and sand is added. The roots of the plant are carefully straightened and sprinkled with earth, compacting the soil from above with the palm of your hand. Then each bush must be watered under the root with warm water. You can add a little urea and wood ash to the hole, or sprinkle it on top of the soil, slightly loosened it.
Site selection and soil requirements
Roxana is suitable for indoor and outdoor cultivation. A site for strawberry plantations is chosen on a hill. A slight shadow is allowed. The soil must be nutritious; acidic soils with limestone content are not suitable.
Preparation of seedlings
For planting in the ground, it is important to make the correct selection of seedlings. Bushes must be healthy:
- The leaves are brightly colored, dark green in color.
- There are no spots on stems and leaves.
- The root system is well formed.
Too long roots are cut off. The day before planting seedlings in the ground, each pot of plants is abundantly watered.
The traditional planting pattern for Roxanne is 30 cm between bushes, 35 cm between rows. Italian strawberries form not too spreading bushes, plants can be planted in three rows.
Indoors, Roxana's seedlings are planted on an agro-fabric, this reduces the contact of ripe berries with the soil and minimizes the likelihood of fruit rot.
In addition, the fruits always remain clean, which is especially important for their subsequent transportation for commercial purposes.
How to care
Care for strawberry plantations of the Roxana variety is traditional: watering, loosening, cleaning weeds, applying fertilizers. It is necessary to pay attention to the procedure for preparing plants for the winter, strawberries need shelter for the cold season.
Spring pruning - sanitizing strawberry beds after winter. Old leaves are removed from the plantings along with pests that have hibernated on them. Bushes receive more daylight, a kind of ventilation of the root system occurs. In the plant, metabolic processes are accelerated, the growth rate increases. Using a rake or a hoe, the soil is loosened, and diseased dried leaves and shoots are cut off with a pruner.
Important! Healthy leaves and young plant buds should not be cut off.
After the "spring transformation" procedure, the berries are watered and fed. Subsequently, the berries will ripen faster, which will certainly delight gardeners.
Spraying strawberries must be carried out before flowering. A protective barrier to plants during this period is necessary, future fruits are laid, and the plant is most vulnerable to diseases, since it gives all its strength to a set of ovaries.
From folk remedies, potassium permanganate or an aqueous solution of brilliant green with iodine is used. Natural natural antiseptics are antibacterial preparations proven for decades. In the cultivation of strawberries on an industrial scale, chemical processing agents are used.
Spraying at temperatures below -18 C and above +30 C is not recommended, plant leaves may get burned.
The introduction of mineral and organic fertilizers is an important stage in the care of Roxana strawberries. Top dressing can be applied using a drip irrigation system, manually sprayed leaves, watering at the root. In the spring, the plants are supported by the introduction of nitrogenous fertilizers. Proven recipe: 20 g of ammonium nitrate per 10 liters of water. The bushes are watered at the root, getting on the leaves is undesirable.
The next top dressing is an aqueous solution of bird droppings or infused cow cakes. For 10 liters of water, it is enough to dilute 1 kg of fertilizer. During flowering and a set of fruits, berry bushes are fed with an aqueous solution of wood ash: 1 glass of ash per 10 liters of water.
After the last harvest, the plants need fertilizers containing potassium and phosphorus. It is always recommended to loosen the soil after fertilization and sprinkle the bushes with humus.
Roxanne is demanding for watering. This procedure should be carried out often, but not to allow waterlogging of the soil and stagnation of moisture at the roots of plants. Water for irrigation should be clean and warm, the optimum temperature is +20 C. Mulch retains moisture in the soil, if it is available on the beds, there is no need for frequent watering.
Humidification is carried out after harvest, in the morning or evening hours. An excess of moisture in the soil leads to rotting and diseases of the berries, and a lack of moisture in the soil leads to a decrease in yield and a decrease in the size of fruits. The gardener should assess the moisture content of the soil before watering.
Regular loosening will help improve oxygen access to the roots and activate metabolic processes between the soil and plants. In the aisles, the soil is loosened to a depth of 10 cm, at the roots of plants, directly under the bush - by 3 cm.
The root system of strawberries is located close to the surface of the beds. After loosening, the bushes are sprinkled and sprinkled with humus.
Roxana has an average winter hardiness. The variety is able to withstand frosts of at least -20 C, it is recommended to cover strawberries for the winter using film covers or textile covering material. You can use spruce branches and straw. In regions with little snow in winter, the Italian strawberry variety can freeze out.
Berries are covered after preliminary preparation of berries for winter: loosening, removing weeds and feeding.
Disease and pest control
Breeders at the genetic level have protected the variety from powdery mildew disease. The plant's immunity is stable, but this does not mean that strawberries are not sick with anything. Anthracnose or black spot is a dangerous disease that often plagues Roxanne. This disease is fungal and occurs in conditions of high humidity. Prevention of anthracnose consists in spraying the plants in spring with Bordeaux liquid.
Protection against diseases consists in timely and regular inspection of plants for diseases. Ailments identified at the initial stage are easily treated and do not affect the yield in any way.
Roxana strawberry propagation
The Roxana strawberry variety is propagated by a mustache. The formation of a mustache in the Italian variety is average. Next to the plant, 2-3 daughter bushes are added dropwise, the rest of the mustache is cut off. In autumn, matured young plants are transplanted into permanent beds.
The transplanted bushes need shelter from the sun and watering for the first few days. Top dressing of young plants is carried out in the fall, during the preparation of seedlings for winter.
Collection and storage of varieties
The transportability of Roxana fruits is excellent. Ripe fruits can remain on the bushes for up to a week without changing the taste. The berries do not give juice and do not lose their shape.
The collected fruits are stored in fruit boxes, wicker baskets in a cool dark place. It is important to provide ventilation in containers with the harvested crop. Roxanne fruits can be frozen and preserved whole. Italian variety strawberries are suitable for decorating desserts. After defrosting, it retains the entire range of vitamins and nutrients.
The Italian berry will decorate strawberry beds. The high yield is combined with the unpretentiousness of the variety. Roxanne can be grown by a novice gardener. In industrial greenhouses, the berry can bear fruit throughout the year. The fruits retain their presentation for a long time and do not lose their taste.
