Features of growing red currant
Redcurrant is a nutritious berry that grows in many areas. The shrub is characterized by high productivity and precocity. Each summer resident should study the features of growing this crop in order to receive a rich harvest every year.
Description of culture
Redcurrant belongs to the category of small deciduous shrubs, which are located in the gooseberry family. Best of all, the berry develops on the territory of European and Asian states, as well as in Siberia. For this reason, the regions of central Russia are considered the best option for growing red currants. Wild berries ripen on the edges of the forest, river banks.
The Dutch were the first to plant red currants in the 5th century. However, in those days, this shrub was used as an ornamental, so the currant was often used as an element of the landscape. Later, people were able to appreciate the taste and useful qualities of a valuable berry and began to grow it for harvest.
Shrubs appeared in Russia in the 15th century and quickly won love among gardeners.
Features of red currant are as follows.
- It is an early maturing crop with good yields. It belongs to the category of perennial plants.
- If we compare red currants with black ones, the bushes of the first shrub are more compact in size. The shape is slightly elongated and shrinks on the sides.
- The shrub has developed roots that grow deep in the ground. Due to this feature, the plant receives nutrients and actively develops every year.
- Young shoots are characterized by a yellow color, which becomes green during maturation. The height of an adult currant is 100-200 cm.
- In the spring season, many leaves grow on the shrub, which are medium in size and can vary in shape. It is allowed to have whole, three-blade and five-blade leaves, which are arranged in turn.
- The outer part of the leaf is dark green, has a smooth and shiny surface. There is a lighter color on the lower part, and the surface of the leaf plate is matte, with a small degree of pubescence.
- There are many buds on the bush, so each shrub brings a large amount of crop.
- In spring, the buds turn into simple flowers, which may have a green or red-brown color. The buds are collected in racemose inflorescences.
- Berries begin to appear later, compared with the fruits of black currant. Due to this feature, the shrub is practically not affected by frost.
- The fruits are juicy and sour in taste. The size can reach 1 cm in diameter. On the bushes, beautiful brushes of a hanging type are formed. The color scheme of the berries can be different: from dark red to pink.
- The life span of a red currant bush reaches 35 years.
- The fruits have many health benefits. They can remove harmful substances from the human body and contain many vitamins in their composition.
What can be planted nearby?
There is an opinion that other types of plants cannot be planted near the red currant.However, most gardeners want to completely use the free space on their site, so they are looking for options for combining vegetation. Since redcurrant is a plant with a high degree of chemical activity, it is not allowed to place varieties that have a similar composition or components next to it.
It is best to have honeysuckle bushes, yoshta, apple trees, as well as strawberries, onions, garlic and other varieties of spicy vegetation near the red currant.
Nightshade
Near currants, it is allowed to plant various types of nightshade crops. Tomato, pepper and other plants will benefit from such a neighbor. Phytoncides present in currants will help repel pests.
Honeysuckle
These shrubs are similar to currants. They also contain vitamins from group C, they are highly resistant to frost and do not require special care. Honeysuckle is characterized by the presence of chemical compatibility with currants.
Yoshta
Yoshta can develop normally next to gooseberries or currant bushes, as it belongs to the category of their hybrids. This is a hardy shrub that is not afraid of any neighbors. It is often planted near currants, as it is not afraid of their typical disease - a kidney mite, which contributes to the development of terry.
Apple tree
An apple tree is considered the best option for a neighborhood next to a currant. Both crops will not adversely affect yields and will be able to fully develop.
Landing next to other species
Many gardeners plant strawberries or strawberries between rows of currants.With such a neighborhood, there is one significant drawback, which is the inconvenient assembly of fruits. Currant does not have a negative effect on strawberries and protects them from various pests. Onions and garlic can act as a defense against the bud mite, which is a common disease among currants.
Next to which plants is it undesirable to plant red currants?
There are several key factors that have identified several undesirable neighborhoods for red currants. It is undesirable to plant shrubs near plants that are susceptible to similar pests or diseases. For currants, such a plant is gooseberry. Both types of shrubs suffer from gooseberry moth, so such a neighborhood is inappropriate. Black currants are an undesirable neighbor for red currants (white currants will also feel uncomfortable). If these crops are planted side by side, a decrease in yields will be observed on the site.
Landing
Red currants can be planted in open ground in spring or autumn. However, in shrubs, the vegetation process begins very early, so the autumn period is considered the best option. You can plant currant seedlings on a hill and in areas where there is high-quality lighting. The shrub loves sandy or loamy soil type. The plant does not impose requirements in relation to the content of minerals in the soil, but with a lack of components, the currant will begin to drop ovaries with fruits.
If planting is done in the fall, experienced gardeners recommend starting it in September.
Step-by-step instructions for planting currants are as follows.
- The first step is to prepare the landing holes. 21 days before disembarkation, you will need to create a hole, the depth of which is 40 cm, the width is 60 cm.
- Humus (two buckets) is poured onto the bottom of the hole along with complex mineral fertilizers. After that, you can add fertile soil and irrigate. This procedure makes the earth denser.
- After three weeks, you can start landing. The roots of the bush should be cut a little, and the plant itself deepens by 8 cm. Bury should be slightly higher than the root collar. This method of planting has a positive effect on the development of the basal bud.
- Planting shrubs should be carried out in the top layer of soil. If you plant it in a fertilized level, the bush will begin to grow actively, and the fruiting process will be delayed.
- The planted bushes are watered, and the shoots are pruned. The stems are shortened at a height of 25 cm from ground level.
- Then the earth is mulched with straw, peat or fallen leaves.
- When the soil begins to freeze, add a little humus. Such an additive will act as a protection of the roots from accumulated moisture.
Care
Red currants should be properly cared for. Only with proper care will the shrub be able to please its owner with good yields and development. Care consists in watering, fertilizing, pruning and tying bushes with a large number of fruits. Around the bush should systematically loosen the soil and remove weeds. The periphery of the near-stem bush should be dug up. You need to act carefully to avoid damage to the root system.
Watering
Redcurrant loves moderate watering. Frequent watering will be required in hot weather.Also, the plant will need to be watered frequently after flowering, when the fruits begin to ripen. In order for the soil in the near-stem circle to be wet for a long time, mulching will be required. This simple method reduces maintenance time, as mulched soil does not need to be weeded or loosened.
top dressing
Growing currant bushes includes feeding. During its development, the plant spends nutrients that are located in the ground. In order to observe high-quality fruiting every year, you should systematically replenish food supplies. To do this, you will need to add mineral and organic fertilizers to the soil.
In the spring, it is best to use a mixture that consists of the following components:
- compost (5 kg);
- superphosphate (20 g);
- potassium sulfate (25 g).
These figures are calculated per square meter. You can also feed the soil with urea (15 g) or ammonium nitrate (25 g per square meter). After the currant has faded, you should add liquid mullein or chicken droppings under the bush. After the harvest is completed, in the autumn season it is recommended to use 100 g of superphosphate, 30 g of potassium chloride for each bush. After that, you can start mulching the soil with rotted manure. Some summer residents use foliar top dressing.
During flowering, you can use the following solution:
- 0.5 small spoons of boric acid;
- 10 liters of warm water.
The resulting mixture should be sprayed on the shrub. And if the currant is located on light sandy soil, in June you will need to feed with slurry.The proportions are: 1 liter of fertilizer per bucket of water. Alternatively, you can use bird droppings.
pruning
Before pruning, you should decide for what purpose this process is planned. There is anti-aging pruning, shaping and sanitary measures.
Anti-aging
If you want to rejuvenate the bush, they resort to removing the most unproductive branches. You should also cut off the shoots on the ring.
Features of anti-aging pruning are as follows.
- You need to remove darkened and too thick branches. You will need to check for branches affected by lichen (they are also removed).
- Cutting should be carried out at the root. Stumps should not remain.
- The cut point must be treated with a garden decoction. It is a mixture that contains wax, vegetable fat and rosin.
- If there are many zero shoots in the depths of the bush, you need to remove some of the branches and leave only the strongest ones.
- After the pruning process, feeding, abundant watering and mulching of the trunk circle will be required.
Bush formation
During the formation, the bush is given a certain look, which must be constantly maintained. Based on the frequency of planting, more or less branches should be left. If planting is too frequent, pruning should be more intense. During this event, branches of different ages should be left on the bush. Due to this, the currant will constantly bear fruit and quickly recover. Most often, during pruning, they resort to standard formation.
Such a form is created as follows.
- After landing, you need to leave only the main shoot and shorten it by half.
- The next year, in the autumn (if two-year-old bushes were purchased), the buds should be removed along the entire height of the bole, leaving only 4 shoots that look in different directions. The skeleton of a shrub is determined in a similar way.
- In the third year of development, all basal shoots and growths located on the stem should be cut out. Strong shoots are shortened by half, on the outer bud. The length of the conductors remains unchanged.
- In the spring, all weak and broken branches should be removed. In the summer you need to shorten unproductive branches.
Sanitary pruning
This event starts in the spring. During it, the branches affected by frost, broken and growing inside the crown, are removed. Sanitary pruning is done throughout the growing season. If parasite-infested kidneys are found, they are also removed.
The conditions for sanitary pruning are as follows.
- The center of the shrub should be freed so that all branches can be evenly illuminated.
- In autumn, side branches should be removed halfway to the outer bud. Using this method, branching is activated.
- After pruning, 4 shoots of different ages should be left. Due to this method, the bush will actively bear fruit and develop.
- The cut should be located no further than 5 mm from the kidney. The secateurs should be placed at an angle of 45 degrees with respect to the branch.
- It is not allowed to trim the tops, which are 2-3 years old. This is due to the fact that with their help the currant bush actively bears fruit.
- If branching is observed and one of the shoots is directed downward or in a horizontal plane, such a branch will need to be removed.
- All horizontal shoots must be removed so that the berries are located at the upper levels.Such fruits will receive more sunlight and ripen faster.
- Bushes should not be allowed to thicken. A couple of strong zero shoots should be left annually, and the rest should be cut off.
- From the fourth year of development of the bush, you can start cutting at the root of the old branches.
- In the spring, root shoots are removed. In autumn, you need to shorten the secondary shoots by 10 cm per bud that grows outward.
- Branches without fruits are removed under the root on the ring. Stumps cannot be left. If thickening shoots are being removed, all cuts should be made at ground level.
reproduction
The easiest way to propagate red currants is by cuttings or layering. When choosing this method, the young bush will be able to completely repeat the original bush.
Propagation with cuttings
In the last days of August, during anti-aging pruning, you will need to cut off a couple of shoots and cut them into several pieces (20-25 cm). All foliage is removed. Each shoot should have several buds (4-5 pieces), the lower cut should be oblique. It should be placed 1 cm below the kidney. The top cut must be placed at an identical distance. All cuttings are dipped in Kornevin and planted in the ground for permanent residence. Alternatively, rooting can be carried out. It is produced in a separate bed, where loose earth is present.
Planting the future shrub should be done at an angle of 45 degrees. Two kidneys are immersed in the soil, and the rest should be located above the ground. When planting, a distance of 15-20 cm between plants should be observed. Then the cuttings need to be watered, the soil is mulched with loose compost, dry earth or peat.The soil should not be allowed to dry out. In the last decade of autumn, the cuttings have time to take root and form shoots the next year.
Reproduction by layering
This method of reproduction is best done in the spring. For this, last year's shoot is selected and bends down to the ground, where a groove has been created in advance (the depth of the hole should be 5-8 cm). The shoot should be laid in such a way that its upper part is located on the surface, and the body itself is in a recess. Pinning is carried out using a wire arc, after which the shoot is sprinkled with loose soil by 1 cm.
When the shoots from the buds grow 10 cm, they should be sprinkled with loose soil to the top foliage. The soil must always be moist. You need to pour the soil several times during the summer season. In September, you can cut off the shoot from the original bush and carefully dig it out. The branch is cut into several parts (depending on the number of rooted shoots), and the formed segments are planted at a permanent place of residence.
Graft
Many gardeners resort to grafting. Redcurrant can take root on different plants: on blackcurrant, cherry, gooseberry, mountain ash. As a rule, grafting is carried out in early spring or summer. The choice of time depends on what material is used for the rootstock. In spring, it is best to use lignified shoots that are prepared in advance in autumn or winter. Grafting can solve many problems, but most often a similar process is used to create a currant tree. Grafting is carried out as follows.
- On the stock, you need to choose the strongest shoot, which is located vertically. The remaining processes are cut under the root.
- Then you should choose a stalk identical in diameter for the scion.
- On the bottom of the scion, you need to make an oblique cut. The length of the cut should be three times the diameter of the cutting. After that, the shoot is placed in a glass with "Heteroauxin".
- On the rootstock, an identical cut should be made at the required height. As a rule, this parameter is 60 cm. The cut point is also wetted with "Heteroauxin".
- Then the cutting must be removed from the solution and a tongue should be made on the lower cut, the length of which is a couple of mm.
- The stalk is applied to the rootstock and the place of the incision is outlined, which should coincide in its location with the tongue. Then an identical tongue is created on the stock.
- Now you can dock the scion with the rootstock, like a puzzle.
- Then the grafting site is tied with a copulation tape or similar material.
- The upper part of the shoot with the strapping must be covered with garden broth. The kidneys that are located on the trunk should be blinded. After that, the plant is tied to a support.
- A similar method can be used not only during the formation of stems. This method is considered the best option for grafting in the spring.
Diseases and pests
Red currants are often attacked by various insects. Also, this plant can be subject to various diseases. To cure the plant and exclude its death, you should familiarize yourself with the main diseases of the shrub.
Many summer residents are faced with the following problems.
- Aphid attack. The plant begins to lag behind in development, the foliage fades and wrinkles. Red bumps appear on the surface of the leaf plate. As a rule, aphids gather on the inside of the leaf.
- Ognevka. This parasite leaves behind a thin web that completely infects the plant.You can also see small caterpillars that eat the green mass of the bush.
- Yellow sawfly. This pest is engaged in laying larvae, which gradually eat the entire plant.
- Spider mites. Characteristic signs: withered foliage, the presence of a sticky web on the stem.
- Kidney mites. They are a distributor of a dangerous disease - baldness. The disease is incurable, so the currant bush dies entirely. The disease can be recognized by the changed shape of the leaf, the absence of color and ovaries.
- Moth. This is a caterpillar that eats red currant leaves completely.
- Zlatka. She eats the juicy part of the shoots.
You can fight these pests with the help of special means. A good result was shown by Fury, Fufanon, Karbofos, Aktara, Bankol, Confidor, Biotlin. Some summer residents resort to folk methods. Spraying is actively used with a soapy or garlic solution, as well as powdering with ash. All affected areas should be removed and burned.
Anthracnose
This is a fungus that appears due to damp and humid climatic conditions. You can recognize the disease by small brown spots, which soon begin to grow and absorb most of the foliage. Fungicides are used to treat anthracnose. For prevention, you can use Bordeaux liquid or a solution of copper sulfate. These drugs can be used as medicine. To do this, increase the frequency of treatment (once every seven days).
powdery mildew
The disease is a thin white "web" that braids the entire plant completely. You can cope with the scourge with a solution of iron sulfate, the concentration of which is 3%.
The soil of the affected bush will also require treatment with Nitrofen
goblet rust
You can recognize the disease by yellow-orange spots that actively affect the entire plant. At the moment, there is no effective way to combat goblet rust, so Bordeaux mixture, the concentration of which is 1%, can be used as a prophylaxis.
