Variety of red currant Roland: pros and cons
Currant Roland for many years is one of the twenty best varieties of the red variety. It is popular among gardeners because of a number of positive characteristics and ease of cultivation. Description of the variety, planting and care features are presented in the article.
Variety Roland represents the Dutch selection. During its breeding, breeders crossed the currant Rosetta and Jonker van Tets. Berry bushes of the described variety are suitable for cultivation in the Central region and central Russia.
Did you know? The name of the currant comes from the old Russian word "curry" — it means "smell good." The plant was so named because its leaves emit a strong aroma.
The bushes of the described variety grow medium in height. Their shoots are strong - as the plants grow older, and under the weight of the ripened fruits, they scatter strongly. The leaves are five-lobed, dark green in color with a yellowish tinge, with a deep notch at the base and sharp ends.
Flowering occurs in late May - early June. The flowers are collected in long brushes, which reach 12 cm. Each brush contains about 30 reddish or yellow buds.
Variety Roland is classified as promising, since it is characterized by unpretentiousness in care and a number of positive characteristics. It can be grown for both personal and industrial purposes. It is suitable for mechanized harvesting.
Drought resistance, frost resistance
During many years of cultivation, the Roland variety showed excellent resistance to frosty temperatures and droughts. The first parameter allows you to grow it in areas that are located somewhat north of the cultivation areas recommended by the originator.
Productivity and fruiting
Fruiting occurs on average - in mid-July. Its duration is 25 years. From one mature bush you can remove up to 7 kg of fruit, which is a very good indicator.
Berry size, taste
Roland is a large-fruited and self-fertile variety. Berries reach a mass of 0.9-1.5 g. They are rounded in shape. Their skin is bright red. The taste of fruits is sweet and sour with a predominance of acid. The pulp contains large seeds. The berries contain 8.9% sugars, 2.5% acid, 23.7% vitamin C.
Advantages and disadvantages
- According to gardeners, the Roland variety has such positive qualities:
- plentiful and stable productivity;
- increased level of frost resistance;
- excellent quality of fruits;
- drought tolerance;
- strong immunity and excellent resistance to diseases and harmful insects;
- universal use of the crop.
- Among the minuses are called:
- sprawling bushes;
- damage by a kidney tick with violations of agricultural technology.
To plant the currant correctly, you need to choose a good place for it, high-quality planting material and observe the technology.
You can plant Roland currants in spring and autumn. It all depends on the region where it is planted, weather and climate conditions. In areas with mild winters, it is better to do this in the autumn, in September. Where the winters are harsh, in order for the seedlings to adapt to frost, they need to be planted in April.
Not every soil is suitable for growing red currants. So, this culture does not grow well in too moist, sandy, clayey, heavy soil. In the area where it is planned to be planted, groundwater should not come closer than 1.5 m to the surface of the earth.
The best crops are observed when planting in chernozem, loamy, sandy loamy, humus-rich soils with neutral or low acidity. Despite the fact that red currants are distinguished by good adaptive qualities, cold, densely shaded, moist and wetlands are not suitable for its cultivation.
Choosing the right place
For the cultivation of berry shrubs, it is necessary to choose a site well lit by sunlight, sheltered from drafts on the north side. When grown in the shade, their productivity decreases, size decreases, the taste of the fruit worsens.
Selection and preparation of seedlings
In order not to encounter problems in the growth and development of the plant in the future, with the invasion of pests and the spread of diseases, it is important to choose healthy seedlings for planting. You need to buy them in a specialty store or a well-established nursery. It is not worth taking them from the market, since there is no guarantee that this particular variety is for sale, or that it is not infected with an infection.
Seedlings are sold with open and closed rhizome. If the planting is planned to be carried out immediately after the acquisition, then it is better to take an open planting material: this way you can assess the condition of the root system. It should be well developed, with 2-3 main strong roots 20 cm long.
The optimal age of the seedlings is 1-2 years. Younger and older specimens are not suitable for planting due to prolonged adaptation and the likelihood of death. Two-year-old shoots should have several strong shoots formed.
If planting is done in the fall, the pits are also dug up 2-3 weeks before the planned date.
Recommended sizes: depth - 40 cm, width - 50-60 cm. Since the bushes of the variety are widely spread, for normal growth of the plant must be placed at a distance of 1.5 m. Between the rows should be left at least 2 m.
The soil extracted by digging holes must be mixed with fertilizers: manure or compost (4 kg), superphosphate (130 g), potassium sulfate (25 g). If the soil is too acidic, then lime (0.8 kg / m²) should be added to it.
The landing algorithm is as follows:
- At the bottom of the pit, make a small hill out of the ground.
- Put on it the roots of the seedling, evenly distributing them.
- Tilt the barrel at an angle of 45 °.
- Fill the pit with earth.
- Dig a trench along the entire diameter at a distance of 20 cm from the trunk.
- Pour 10 l of water into it gradually.
- Cover the trunk circle with a layer of mulch from humus and peat.
- Trim the shoots, leaving 10-15 cm with 3-4 buds.
When planting, the root neck needs to be placed to a depth of 5-6 cm. The correct deepening will give an incentive to the growth of lateral roots and shoots of substitution.
Roland currants require standard care: watering, top dressing, loosening, weeding, mulching, pruning.
In order to avoid the development of diseases, water should not be poured under the trunk, but in a previously dug groove at a distance of 20–25 cm from it — this will prevent contact of moisture with ground organs.
For adult shrubs, in which the root system is already fully formed, 1-2 waterings per month will be enough. Be sure to moisten the soil during flowering and fruit loading.
A day after watering, the soil around the bush should be loosened 6-8 cm deep. This is necessary to improve the moisture and air conductivity of the earth, the normal flow of water and oxygen to the roots.
An important care measure is weeding. Weed herbs pose a threat to cultivated plants, as they become carriers of infections and pests, they take away sunlight and moisture. Weeds must be removed with roots, in order to avoid their further growth.
To reduce the amount of irrigation, loosening and weeding, you need to cover the near-trunk zone with a layer of mulch from straw, sawdust, pine needles, peat, humus, mowed grass. Using this procedure, it is possible to maintain an optimum moisture level in the soil and to delay the development of weeds.
Abundant and high-quality crops are possible only with regular fertilizer application. Feeding is carried out during the growing season, start in March and end in October.
When scheduling, you can use the following recommendations:
|Due date||Fertilizer Options|
|the beginning of June|
In addition to the proposed options, you can also use special ready-made mixtures designed for feeding currants, which are sold in garden markets.
One of the advantages of Roland shrubs is that they do not need frequent pruning. If necessary, remove old branches that no longer bear fruit, as well as those that have dried, twisted.As it grows and during the formation of the fruit, props should be installed under the fruiting branches.
Currants of the described variety tolerate frosts well. Mature plants do not need shelter. You can simply bend the branches to the ground and fix them. It is imperative to shelter young plants. To do this, you can use agrofiber, burlap, coniferous branches.
After the snow falls, it is necessary to pour it on the bushes. To insulate the roots, it is worthwhile to mulch the root zone. Peat, dry sawdust, spruce branches are suitable.
At home, it is faster and easier to propagate currants with green and lignified cuttings.
Harvesting green cuttings involved in June. They are cut 7-8 cm long together with part of the branches on which they grow, and then planted for rooting in loose soil, buried 3-4 cm deep. The green part is placed vertically, and the section of the mother plant is horizontal.
After planting, the cuttings are moistened with such an amount of water so that it penetrates to a depth of 5–7 cm. Before the roots appear in the plants, they are moistened every day, after which they reduce the number of irrigations to one in 2 days. They are transplanted to a permanent place after one year.
Lumber cuttings are harvested after autumn pruning until September 15th. Choose the strongest shoots and cut from them parts of 18–20 cm long with four or more buds. The upper section is placed above the kidney and made straight. The bottom is cut at an angle of 60 °.
Then the cuttings are placed in a rooting agent, for example, “Kornevin”, and planted in loose light soil at an angle of 45 °. With regular moisturizing, rooting should occur within a month. After this, you can transfer to the site.
The first harvests from shrubs grown from cuttings occur 3 years after planting in a permanent place. In addition to cuttings, shrubs can also be propagated by root shoots. Her plenty is formed at the base of the trunk in the fall.
Important! The latest date for planting cuttings in the ground is mid-October. If it was not possible to plant them before this date, they should be stored in cool conditions, wrapped in polyethylene or burlap, for subsequent planting in the spring.
Diseases and Pests
Variety Roland is resistant to major diseases and harmful insects. When conducting quality care and preventive measures, the owner of the site will not have to worry about chemical treatment.
It is advisable to carry out the following preventive spraying:
- In early spring, with the preparations Ftalan, Kuprozan, Khometsin against fungal infections - powdery mildew, anthracnose, septoria, and gray rot.
- Against pests - means "Karbofos", "Actara", "Zolon".
If small brown spots are noticed on the leaves of the currant, and the shoots do not grow well, this indicates infection with anthracnose. It must be treated with copper-containing preparations, for example, 1% Bordeaux liquid or copper sulfate. A white powdery coating indicates a defeat by powdery mildew. It is also treated with agents containing copper.
Of the pests, the biggest danger is the kidney tick: it leads to an increase and bloating of the kidneys. They are fighting with him "Bi-58", "Phosphamide", "Nissoran", "Marshal".
Harvesting and storage
Harvesting can begin when the berries have reached the mass, size and color stated in the description of the variety. The collection should be planned for the morning or evening of a cloudy, non-hot day. It is necessary to wait until the peel of the berries dries from dew - wet and cleaned fruits are less stored.
Did you know? At the beginning of the 20th century, American authorities banned the cultivation of currants and gooseberries, as these plants carried the fungus Cronartiumribicola, leading to serious illness and death of pine trees. The ban was lifted only after 60 years.
Tear off currants manually. The gardener needs to carefully lift the branch with one hand, and with the other to pick the berries from the branch, without separating them from the stem, and putting them in a container of 6-8 kg. Fruits that are planned to be transported in the future must be harvested at the stage of technical maturity and immediately placed in cold conditions after harvest.
For storage, currants should be placed in the refrigerator. There she can lie for 2 weeks. When stored in temperature conditions 0 ... + 1 ° C, the shelf life is extended to 3 months. To be able to consume currants throughout the year, it can be frozen. When freezing, it is possible to preserve almost all the beneficial substances of the berries.
Currant Roland is consumed fresh. To do this, wait for it to mature and gain the maximum amount of sugar. Also, stewed fruit, juices, jelly, jam are made from it, used as a filling in baking.
So, Roland currants are well suited for cultivation in cottages and household plots. It is unpretentious, practically does not get sick and is not damaged by pests, it brings tasty and high-quality fruits. For its successful cultivation, you need to choose a suitable place, buy quality seedlings and carry out regular care.
