Remontant varieties of berry crops have gained popularity due to their positive qualities. Everyone wants to enjoy delicious Korona strawberries all summer long. Despite the fact that the variety was bred by Dutch breeders, it takes root well in the middle lane and gives high yields of berries.

Description and characteristics of the Crown

Strawberries are bushes with large concave leaves. On powerful flower stalks, fruits ripen. At the same time, the stems do not fall down under their weight. The features of culture are not only a decorative appearance, but also unpretentious care.

History of selection

A hybrid appeared in the 70s of the XX century. Dutch breeders worked on its breeding. By crossing the Tamella and Induka strawberry varieties, they got a wonderful plant. From parents, it received the best taste, resistance to weather disasters.

Growth region

The resulting strawberry variety is zoned for areas with a temperate climate. Bushes withstand frosts below 20 degrees.

You can grow it in the south. There, the bushes will bear fruit throughout the growing season. Hence the popularity of the remontant type of strawberry among gardeners.

Bushes

Bushes of a perennial plant reach a height of 20-25 centimeters. The strawberry root system is a perennial rhizome in the form of a modified stem with skeletal roots and small roots penetrating into the ground to a depth of 20 centimeters.Away from the mother bush, the roots go 10-20 centimeters.

Short side stems are formed on the short main stem. They branch, forming the shape of a bush. Trifoliate large leaves of the Crown are painted green. During the summer they are replaced up to 2 times.

Flowers and berries

At the top of the shoot are buds that give flower stalks. From the apical kidney, brushes of flowers and fruits are formed. The more upper buds Korona strawberries have, the higher the yield of berries.

White flower petals fall off, berries with seeds form in their place. What distinguishes them:

  • dark red color;
  • oval-conical shape;
  • weight up to 25-30 grams;
  • juicy pulp with a balanced content of sugar and acid;
  • strawberry flavor;
  • smooth, shiny surface.

The tendrils are formed from the buds in the lower part of the bush, which are necessary for the propagation of a garden plant.

Strawberry yield

Gardeners choose Corona because during the summer you can collect up to a kilogram of delicious, large berries from 1 plant. The variety is also grown on an industrial scale. From 1 hectare of the field, farmers collect about 12-14 tons of fruits.

Transportability

The juicy pulp of the fruit is so tender that it just melts in your mouth. But it is difficult to transport such a berry. Dear, she will remember, she will release the juice. Therefore, it is necessary to collect unripe fruits in order to bring them to the market.

Advantages and disadvantages of the variety

It has been more than 40 years since the Korona strawberry appeared. But gardeners continue to give preference to the remontant species. And all this thanks to the fact that the hybrid:

  • ripens early;
  • gives consistently high yields;
  • successfully grows in any regions;
  • resistant to low temperatures.

Among the disadvantages is that strawberries are only suitable for fresh consumption. Do not make jams from it. She quickly loses shape, spreads. Therefore, it is difficult to transport the berry over long distances. The culture is also prone to fungal infections.

How to grow strawberries

To enjoy delicious strawberries, you need to prepare a plot for a berry crop. Comply with the terms and rules of planting plants in open ground.

Preparation of planting material

Saplings with: are used for planting strawberry plantations

  • fibrous root system 5 centimeters long;
  • 3-4 leaves;
  • he althy central kidney.

If the roots are long, then they are shortened to 5-7 centimeters.

Date of planting

It is best to plant Corona strawberries from the beginning to the middle of May, depending on the region. You can also land in August, until mid-September. Seedlings planted in the morning or evening, in cloudy weather, take root well.

Preparing the beds

The place for the culture is chosen with fertile, weed-free soils. It is better if it is loamy black soil. Slopes in dry areas are suitable for planting northwest, north, northeast.

If you plan to plant in the spring, then you need to dig the site in the fall to a depth of 27-30 centimeters. Before planting, cultivate a plot 15-18 centimeters deep.

Be sure to bring before digging up to half a bucket of rotted manure per square meter of plantation. A mixture of 2-3 kilograms of humus and 30-50 grams of superphosphate is also suitable. Used for planting strawberries between rows of currants or fruit trees.

Planting strawberries

The yield of strawberries depends on the distance between the bushes. It is necessary to plant bushes with an interval of 30-40 centimeters. And between the rows leave 80-90 centimeters. Holes are dug by hand, placing seedlings there to a depth of 10 centimeters. The roots should not bend, and the central kidney is at ground level. Holding the seedling with one hand, sprinkle the ground with the other to the level of the heart. It remains to slightly compact the soil and water the strawberries, spending 0.5-1 liter of water on the plant.

It is necessary to shade the plantation for 3-4 days with straw, dry grass, needles. Row spacing is also mulched with a layer of 6-8 centimeters. 2 days after planting, the position of the central kidney is checked. If it is covered, then the earth is raked.

Rules for the care of strawberries

Caring for the Korona variety should be the same as for other types of remontant strawberries. Although the culture is moisture-loving, it does not tolerate stagnant water. Plants are highly demanding for food, but an excess of nitrogenous substances in the soil leads to strong vegetative growth to the detriment of fruiting.

Necessary feeding

Fertilization is carried out according to the scheme:

  1. For the first time in spring, you need 10 grams of ammonium nitrate and 15 grams of superphosphate for 1 square meter of planting. You can put dry fertilizers into the ground with a chopper or a shovel, liquid fertilizers are prepared by dilution in a bucket of water.
  2. Before the appearance of flowers, the bushes are watered with a solution of mullein at a concentration of 1:6 or bird droppings - 1:20.
  3. Replace organics with mineral mixtures of 10 grams of ammonium nitrate and potassium s alt per square meter.
  4. After picking the berries, you need to feed with an aqueous solution of 20 grams of superphosphate and 8 each of ammonium nitrate and potassium s alt. Fertilizers promote the laying of flower buds.
  5. In autumn, poor soils need to be fed with potash-phosphorus fertilizers. They are applied dry between rows.
  6. In the 3rd year of plantation life, an additional 2 kilograms of humus per square meter is added, planting to a depth of 10-25 centimeters.

Feeding is combined with soil loosening, which is carried out 4-5 times per season.

Irrigation

Moisturize the planting of Korona strawberries in the first year after planting 4 to 6 times over the summer. 2-3 buckets of water are poured per square meter of plantation. After watering, loosen the soil. Helps to moisten the area with snow retention, which is arranged with the help of currant curtains or shields.

Then it is necessary to water the plants more abundantly: 1-2 times before flowering, up to 3 times during the ripening of berries and after harvest. On sandy soils, the frequency of watering increases. In order for the earth to be well saturated with moisture, you will need 3-4 buckets of water per square meter.

Preparing for winter

Strawberry shelter is a must in areas with cold winters. To do this, in November, when the soil is frozen, the bushes are completely covered with brushwood, straw, spruce branches, dry tops of potatoes or tomatoes. The coating layer should be 8-10 centimeters. In the spring, it is removed, using it for mulching the beds.

Disease and pest control methods

Of the diseases, fungal infections often affect strawberries. They appear as spots on the leaves. Combat spotting by spraying with a 1% solution of Bordeaux mixture. Processing is needed 2-3 times during the growing seasonThe first time the procedure is carried out when the buds are exposed. Then it is repeated every 3 weeks.

Pests attacking strawberries are spider mites, aphids, weevil. You need to fight parasites with insecticidal agents. From the folk they use tobacco decoction, an infusion of onion peel.

Methods of reproduction

Like all berry crops, strawberry propagation is carried out in different ways. The most difficult - seeds. The vegetative method is used by many gardeners.

Seeds

Seeds grow the Crown through seedlings. The seeds are so small that they are laid out on the surface of the nutrient soil, sprinkled lightly with earth. Then they press the landing with glass. Regularly airing and watering, waiting for the appearance of sprouts. As soon as they come out, put the containers in the sun. After the first true leaf, the seedlings dive. And with 3-4 real leaves, strawberries can be planted in open ground.

Usami

Vegetative propagation is easier. Mustaches come from he althy and strong bushes. As soon as rosettes of leaves form on them, they are pressed into the soil.Then watered. After the rooting of the rosettes, the seedling is separated from the mother bush. You can transplant young bushes to a new place.

Dividing the bush

Biennial strawberries are dug up and the bush is divided so that each part is a rosette of leaves. In addition, each part must have fibrous roots. Having cleared them of damage, the bushes are planted in a permanent place.

Features of the fruiting of the Crown

Korona strawberries are valued for their excellent taste of berries. It is difficult to keep these juicy fruits. Therefore, they are collected in the early morning in a container with holes. This will allow excess juice to pour out without stagnation in the cup.

A feature of the fruiting of the hybrid is that every year the berries become smaller. Therefore, it is necessary to renew the strawberry plantation every 4-5 years.
