Blackcurrant: planting, growing and care
Sweet blackcurrant from the bush is a healthy delicacy. Its berries and leaves contain substances that strengthen the immune system. They are not destroyed during heat treatment, and the taste and aroma of berries are preserved even when frozen.
Planting, growing and caring for blackcurrants must be done carefully. You should definitely allocate a small plot of land in the country to this plant, because only one bush will provide an annual supply of vitamins for the whole family.
Disembarkation dates
Currant is considered to be an unpretentious plant. With regard to red and white (golden) varieties, this opinion is true, but blackcurrant gives a good harvest under certain conditions. She loves fertile, and most importantly, moist soil. The taste of the berries depends on the level of moisture. The less water a plant receives, the more acidic it is. The better the bushes “drink”, the juicier and sweeter the crop is.
Currant berries are valued for two reasons: they are tasty and healthy. But currant leaves are no less valuable. They are added to medicinal preparations and herbal teas. In marinades for the winter, they are necessary to prevent the appearance of bacteria.
But useful berries and leaves are obtained only from a healthy and prolific plant. For any bush to become like this, two factors are important: you need to plant currants in time and take care of them properly.
The answer to the question of when it is better to plant blackcurrant seems obvious - in the spring, like other garden crops.However, few novice gardeners know that autumn is a more suitable time of year for this.
Spring planting is carried out immediately after the snow melts. Since each year the last frosts occur at different times, you need to navigate by the weather. As soon as the sun's rays have melted the snow and warmed the upper layers of the soil, blackcurrant cuttings can be planted. This usually happens in late March or early April. It is at this time that the air temperature during the day is optimal - 7-8 degrees, and at night it no longer drops below 0.
It is important not to miss this moment. If you plant seedlings with blooming buds, the plant will take root worse and get sick longer. Pests will easily stick to the sprout, and the blossoming leaves will require a lot of nutrients, which at first are more needed for the development of the rhizome.
Pros of planting blackcurrants in spring.
- Spring is a time of intensive plant growth. At this time of the year, the soil is moist and fertile. And if the nutrients are not enough, the plant can be fed while the ground is loose and soft.
- It is easy to monitor the growth and health of the seedling.
- No need to prepare a young plant for wintering. Over the summer, it manages to develop and take root to such an extent as to survive the winter under the snow.
Disadvantages of spring planting
- It is difficult for a gardener without experience to choose the right time. If planted too early, the buds may freeze.
- In the later stages, it will develop more slowly and worse due to the fact that both underground and above-ground parts grow.
Autumn planting is carried out in the interval between the complete fall of the leaves on the trees and the first frosts. On the calendar, this is the last decade of September or the first half of October.The air temperature, as in spring, is not lower than 0 and not higher than 10 degrees.
When planting in the fall, it is also important to meet the deadlines. Before the first frosts in their lives, young currants should take root in the ground. This takes 4 weeks.
If frosts came in early October, it is better to transfer the planting of blackcurrants to spring. This will ensure that the plant will not die.
Benefits of fall planting
- After harvesting, when the garden plot is empty, it is easier to plan planting for the next year. There is an opportunity to think about which plants next year currants will coexist with, which crops to replace, and for which ones to change locations.
- In spring, seedlings with a closed root system predominate, and in autumn, planting material is mainly sold with an open root system. It immediately shows whether the plant will take root and how correctly the stalk is germinated.
- It is easier to take care of the seedling. Autumn rains and cool temperatures are the best conditions for the plant to put all its strength into the development of the root system, while the buds sleep before wintering.
- Autumn work frees up more time in spring to care for other vegetables and fruits on the site.
- High level of adaptation. This is due to the fact that currant buds swell and bloom very early. They compete in spring with the root system, and in autumn all the forces of the seedling are directed to rooting. In addition, pests do not like the cold season. Nothing prevents the seedlings from taking root properly, and in the spring they immediately begin to grow.
Disadvantages of autumn planting.
- Autumn weather is unpredictable. If an early frost hits, the seedlings will die from the cold.
- Of all the types of pests, rodents remain.They gnaw the tender skin of seedlings, which also often destroys the plant.
How to choose a seedling?
High-quality planting material is a significant share of success when planting black currants. You can choose the planting time as successfully as possible, moisten and fertilize the soil, but if the seedlings are stunted, they will not take root.
In addition to annual seedlings, currant bushes can be propagated by cuttings and layering. Cuttings are a troublesome process, and propagation by layering is possible only if there is already an adult bush on the site. Therefore, for gardeners who save their time, seedlings are the most convenient and fastest option.
Often good seedlings are sold first-hand on the market. Amateur gardeners do not have the habit of hiding the root system in a pot and put up for sale a small amount of planting material. The advantage of this approach is that the seedling can be viewed from all sides. He does not have time to dry out or wither in a short time, as with wholesalers.
In the market there is always a risk of acquiring the wrong variety of seedlings that you need, so it is best to purchase planting material in a nursery. Its choice is large, the plants there are healthy, and the variety and quality are easily checked by a certificate.
Characteristics of a good planting material.
- The seedling is 1 or 2 years old.
- Strong root system. The plant should have developed 2-3 lignified main roots. The length of the roots is not less than 15 cm, the color is yellowish-brown. In addition to the main roots, there should be many white thread-like processes.
- If the fibrous processes are not white, but brown or brown, the plant should not be taken. It has already been ill, frozen or received little moisture.
- If the seedling is sold in an opaque pot, you need to ask the seller to take it out and show the root system. A conscientious seller will not refuse.
- The root system densely braids an earthen clod. This is a sign that the plant will successfully take root in a new place, because the roots in the ground do not dry out.
- In no case should you buy seedlings with washed roots without soil. It is also better to avoid overdried and wilted roots, even if the seller claims that they will come to life again in the water.
- The stalk is at an angle of 45 degrees. It is clearly visible above the root system. This is the correct location of the cutting when cutting, and any experienced gardener knows it. This means that the plant was grown according to all the rules and is more likely to take root.
- The seedling has two shoots no more than 40 cm high. It often seems to beginners that the gigantic size of the shoots, their large number and violent color are sure signs of good planting material. But it's not. The more actively developed the aerial part, the more difficult it will be for the roots to gain a foothold in the new soil. Also, small shoots are easier to tolerate frost.
- The color of the shoots is brown. They are strong and inflexible.
- There are no signs of wilting or spots on the plant. The seedling looks fresh and healthy.
Two-year-old seedlings with young leaves are more suitable for spring planting. In autumn, annual seedlings with dormant buds take root better.
How to plant?
Planting blackcurrant is carried out in open ground. The plant loves the sun, water and natural pollination by insects, so it gives a good harvest in the open field.
Step-by-step instructions for planting currants are quite simple and include only a few steps.
Step one is to choose "neighbors" for currants. The products of modern breeding are mostly self-pollinated plants. However, blackcurrants will flower and bear more actively in close proximity to other flowering plants. But these should not be tall trees and plants from the same gooseberry family.
Both trees and currant bushes have a powerful and branched root system. They will compete with each other for moisture and nutrients from the soil. This will affect the size and taste of the fruit.
Dangerous neighbors for currants are sedge and coniferous trees. They can cause powdery mildew.
Next to their relatives - gooseberries and red currants, this berry is also better not to plant. They are subject to the same diseases. If one bush becomes infected, all the others will also be infected.
The second step is to prepare the planting holes in the soil. The depth of the pit is 40-50 cm, the width is up to 60 cm. The deeper the pit, the more fertile soil will fit into it, so large depressions are better than small holes.
The distance between the pits (if there is more than one seedling) and other plants is 100-150 cm. The distance to the fence or fence should be the same.
When the pits are dug, loose, moistened fertile soil should be poured into them and flavored with a bucket of humus. Mix the substance with a shovel. Immediately before planting the seedling, shed the soil in the pit with water. For a bucket of soil and a bucket of humus - 3-5 liters of water.
Step three - plant seedlings. When the water is absorbed, a seedling should be placed in the hole. Gently straighten the roots so that they lie on the ground and look in different directions, do not get confused and do not lift up. Sprinkle with the first layer of earth 3-4 cm.
An important point: currants are one of the few plants in which it is recommended to deepen the root neck, that is, the place from which the first root grows. Then, roots will begin to grow again from the root collar, which will help the currants to gain a better foothold and receive more moisture and nutrition.
The first layer must be shed with another 3-4 liters of water, allow the liquid to be absorbed. After that, you can sprinkle a second layer of earth.
Step four - shorten the seedlings. Both in spring and autumn, the buds on seedlings will require moisture and nutrition. This gives an additional load on the root system, which is already difficult to adapt. Therefore, you need to shorten the seedlings with secateurs. It is recommended to leave the first 3-5 buds from the cutting (15-20 cm). The rest can be safely cut off. The plant will be easier. All seedlings are planted in the same way.
Care
The life expectancy of a currant bush is 12-14 years. The first two years the plant does not bear fruit, and the period from 4 to 8 years is considered the most fertile. To prolong it and get a tasty and rich harvest of berries, currants need to be properly looked after.
Care includes timely and proper watering, top dressing, treatment and "rejuvenation" of the bushes.
Watering
Among berry bushes, blackcurrant is the most moisture-loving. When the plant receives enough moisture, the berry ripens sweetish, juicy and resilient. When there is little moisture, it is sour, small and too soft.
Currants need to be watered a lot, but correctly. A plant (rooted) has 4 growing seasons when water is most needed.
- The first period is the end of May and June. At this time, the currant blooms, leaves grow. An ovary is formed, from which, after pollination, fruits will develop - berries.
- The second period is July. Berries begin to grow and pour. At this time, you need a lot of water. The exact amount depends on the age of the plant, variety and soil type. Such watering is considered universal when the earth is moist at a depth of 50 cm. It should remain so all the time.
- The third period is after the harvest. The plant spends a lot of moisture on fruits. A significant part evaporates through the surface of the leaves. After the berries are harvested, the roots need to rest and recover.
- The fourth period is pre-winter. It is especially important if the autumn turned out to be dry and hot. In order for the bush to overwinter well, you need to give the roots enough moisture and nutrients to absorb. If the bush “starved” before wintering, you can not wait for the next year to harvest.
top dressing
Growing currants is hard to imagine without top dressing, especially if the soil is not good quality.
Top dressing gives the plant the necessary nutrients, makes the harvest plentiful and tasty. Without it, the currant becomes smaller, voids often appear in the ovary.
There are two ways to feed currants: basal and foliar.
The root or liquid method is the main one. It is different in spring and autumn. In spring, the plant needs nitrogen fertilizers. Nitrogen is present in all tissues of living organisms. It is an integral part of protein, and it is necessary for the growth and development of the plant world.
Nitrogen compacts the root system, helps to form new shoots, leaves and ovaries. It improves soil microflora and helps control pests. With the addition of fertilizers based on nitrogen, the plant blooms better and bears more fruit. All ready-made nitrogen fertilizers are obtained from ammonia. These are urea, saltpeter of various types, anhydrous ammonia, sodium sulfate and other substances.
For those who are afraid of chemistry, there is a natural alternative. Nitrogen is found in manure, coffee grounds, blood meal, and some plants.
Up to 4 years, one bush needs 45-50 grams of nitrogen. In the fifth year, the number can be reduced to 30-40. In autumn, the plant needs a lot of organic fertilizers with potassium, phosphate, magnesium, phosphorus, nitrogen. These substances are found in ash, cake, compost, manure, fish emulsion, tinctures with rye bread.
Liquid top dressing, like watering, is relevant in 4 periods.
- May June. The plant buds, leaves grow, flowers appear. They need a lot of nitrogen.
- June-beginning of July. Active flowering, still needs fertilizer with nitrogen. You can add complex ones.
- July. Berries are forming. Need supplements with phosphorus, magnesium and potassium.
- Aug. Sept. After the final harvest, the plant must be fed before wintering. Complex fertilizers without nitrogen are suitable.
The foliar method is spraying the plant from a spray bottle. It is recommended for June and July.
For the foliar method, mixtures with trace elements (potassium, manganese, copper sulfate, boric acid) are relevant. They are diluted in an amount of 5 to 4 g per 10 liters of water. Then the mixture is poured into a container with a spray nozzle and the bush is irrigated from above.
pruning
You need to trim (shape) currant bushes season after season.
Bushes grow slowly. Every year new shoots are formed, but you can’t leave them all. One shoot bears fruit for 5-6 years, starting from the second year of life. After this period, he simply takes away part of the nutrients, but no longer gives the crop.
In order for the currant bush to produce many berries, all shoots that are more than 6 years old must be cut.This is not difficult, since only a few new shoots appear in a year, which are easy to distinguish from the old ones.
Every year, you need to cut off the old six-year-old shoots and leave new one-, two-, three-, four- and five-year-olds. During such pruning, a sprawling bush of 12-18 branches is formed.
It is correct to start the formation of a bush from the first year after planting in the ground. But seedlings are not completely removed. They are only shortened to 15-20 cm.
It seems to many novice gardeners that leaving only this “slingshot” from a plant is blasphemy. Actually, there is nothing to worry about. By the end of the first year of life, the rooted plant will give several new shoots. Sometimes there are only 2-3 new (also called zero) shoots, sometimes up to 6.
The gardener's task is to cut off the extra zero shoots in the second year of the bush's life. Leave only the strongest and healthiest. Shaded, weak, healthy branches that interfere with the normal growth of healthy branches can be cut without hesitation.
Additionally, in young shoots, the upper part is “pinched”, that is, they are shortened by 1-3 buds. This is necessary in order to form side shoots, on which ovaries and berries will then appear.
In the third and fourth years, the procedure is repeated. Shaded and weak shoots must be removed. Also get rid of old and dry branches. And young shoots continue to form a prolific bush.
The older the bush, the more attention should be paid to the shoots that grow in the middle. Often the sun does not reach them, the fruits do not appear on them. Such shoots only make the bush thicker, take away nutrients and shade the branches with berries.
In the fifth and sixth year, the most important thing is to “rejuvenate” the bush - to remove old lignified branches that will no longer produce berries. They are cut off near the ground.
It does not matter how old the bush as a whole. The annual pruning scheme remains the same:
- two-, three-, four-year-old shoots are shortened for branching up to 3-4 buds from below;
- in last year's shoots, the upper 2-4 buds are cut off;
- of the youngest shoots, only the healthiest, with great potential, are left, and the rest are removed;
- shoots are cut at the root, which are more than 6 years old;
- remove all branches with defects: dry, broken, frozen, shady, stunted, affected by a disease or pest, clinging to the ground.
Pruning can be done in early spring, before the buds have blossomed, and in late autumn, when the leaves have already fallen. In the spring, frozen and broken branches are removed. In the autumn - sick and old.
Dead wood can be removed at any time. It is best to pinch young shoots in summer, in early to mid-July.
reproduction
Black currant is a long-liver among bush berries. But over the years, the fertility of the bush decreases, and the crop is no longer enough for fresh consumption and for harvesting for the winter. And if the variety turned out to be good, it is a pity to lose it.
The bush can be propagated in three ways: cuttings, division, layering.
- cuttings - the most reliable, but the longest way. About 80% of cuttings take root. New bushes grow from them, which bear fruit 2-4 years after planting in the ground. That is, the cuttings need to be planted at 8-10 years of the life of the bush, so that the new one has time to develop and begin to bear fruit.
- The division of the bush is a fast but less reliable way. It lies in the fact that from one bush with a common root system, with the help of a pruner or saw, two new ones are formed. Then, on each of the independent parts, young shoots are mainly left so that the bushes are completely renewed. This approach is always associated with risk.The survival rate of independent parts is worse than that of cuttings. In the worst case, the bush will be completely ruined in vain.
- Division of the bush by layering - a simple way, which also has its drawbacks. It is considered the most accessible for beginner gardeners, since shoots do not even need to be separated from the bush. It is enough to use annual or biennial sprouts and nitrogenous fertilizers for the soil. Young shoots need to be dug into loose soil and fixed in a horizontal position. It is important to fertilize abundantly and water the cuttings regularly so that they take root. Otherwise, all efforts will be in vain.
The success of any method depends on three things: healthy planting material, loose and fertile soil, and plenty of water.
Treatment
Currant attracts many pests and is often exposed to diseases. They affect the quality and quantity of the crop. The berries become smaller, among them there are many dry and sour ones. Reduced bush life. However, most ailments can be prevented in two ways: purchase a currant variety that is resistant to common diseases, and take preventive measures throughout the year.
But even an elite variety of currant from the nursery will not be absolutely invulnerable. It is important to recognize the signs of the disease at the initial stage, before it spreads to the berries and kills the plant.
Anthracosis
Its signs are clearly visible on the leaves. These are black tuberculate spots 1-2 mm in size. If the fungus that causes anthracosis is not fought, it will cover the entire leaf area. Affected leaves dry up and fall off.
Anthracosis is treated with a solution of copper sulfate (Bordeaux mixture). The liquid is diluted in an amount of 10 grams per liter of water. An adult plant needs 10 liters of solution.They are sprayed on the bush immediately after spotting on the leaves and again after harvesting.
powdery mildew
It looks like a whitish bloom on the leaves. Over time, it spreads to berries.
Powdery mildew is easy to deal with. If you react in a timely manner, the plant can be saved. To do this, use ready-made preparations ("Fitosporin"), copper sulfate or improvised means (iodine). For 7-10 liters of water, a tablespoon of the drug is enough.
After treatment, the plant should be plentifully watered and fed. Dew usually appears on bushes that are undernourished.
currant rust
The disease got its name for the characteristic brownish spots that cover the leaves of the plant. Its causative agent is coniferous plants or sedge near the garden plot.
As a treatment, copper sulfate and active fungicides are used. If possible, you need to remove the sedge so that the disease does not return.
Terry
With this disease, the color and shape of the leaf changes. Elongated, asymmetrical, purple-tinged leaves are a sure sign that the currant is affected by terry. You can notice it already in the early stages, and immediately take action.
All affected areas of the bush must be removed. Add more nitrogen fertilizers and potassium to the top dressing, and after harvesting, treat the bush with a special solution (Karfobos is suitable).
In addition to fungi, pests can also cause the disease. These are aphids, moths, mites.
Pests are repelled with the help of solutions and the right neighborhood with other plants. Aphids are afraid of tansy and yarrow. In addition, it is recommended to plant nearby plants that attract ladybugs (calendula, cornflower, dill, parsley, dandelion). These insects will destroy the aphids.
Fire bugs are not harmful in and of themselves.They lay eggs on the currant, and already the caterpillars infect the bush from the inside and outside.
Fireflies are hard to deal with. It is recommended to inspect the bush for the presence of pupae and remove them. You can also lay sheets of roofing material around the bush, so that it is more difficult for pests to get out of the ground onto the bush.
If the plant is affected from the inside, the bush must be uprooted, and a new seedling planted far from this place. Ticks are fought with the help of ready-made preparations and folk remedies.
After any illness, the correct feeding and timely pruning of the affected areas of the bush helps the plant to recover.
Tips from seasoned gardeners
There are little tricks and secrets in handling blackcurrants that make this berry the pride of the garden plot. Experienced gardeners willingly share their knowledge and recommend a serious approach to all stages of berry cultivation, from buying a seedling to harvesting.
First of all, you need to choose the right variety. It should be productive, medium or large-fruited, resistant to diseases and pests. And, of course, the right currant is delicious. After all, it is in its fresh form that it is most useful.
Busy gardeners should pay attention to reliable varieties. They are resistant to disease, drought and frost. Outstanding representatives - "Sofya", "Bagheera", "The Little Prince", "Perun", "Carmelita", "Kipiana", "Crane".
Lovers of sweet and fragrant berries will like "Treasure", "Venus", "Selechenskaya", "Gift of Smolyaninova", "Green Haze".
Large berries (from 1.1 g in weight) from "Tamerlane", "Sensei", "Little Prince", "Sorcerer", "Mermaid". Large-fruited currants need careful care.
For jam, compote and candied, berries are needed that retain their elasticity, color and aroma after processing.These are Chernavka, Elevesta, Labile. Many large-fruited berries are well preserved. They have a dense skin with a high content of pectin.
For easy picking, berries with a "dry separation" are needed. Among the popular varieties are "Beauty of Lvova", "Tamerlane", "Little Prince", "Wizard", "Chernavka".
In order for the currant bushes to be also a decoration of the site, you need to choose elite seedlings. They are as resistant to diseases as possible and delight the eye with healthy leaves and large fruits.
To get the most benefit from blackcurrants, you need at least three bushes of different varieties from early to late ripening so that fresh berries are on the table all summer.
When choosing seedlings, gardeners are advised to give preference to biennial plants. Shoots should be no more than 40 cm in height, with tight closed buds. The root system must be evaluated for moisture, the presence of earth and a healthy color.
No need to buy seedlings without land. You should also avoid plants in opaque black pots - this way you risk getting a "pig in a poke".
The optimal conditions for planting currants are the end of September and October at positive temperatures (7-13 degrees). For landing, you need to choose a sunny and calm side. Shady areas and lowlands will not work. For good growth, the plant needs moist, but not marshy soil.
In order for currants to grow better, they need to be fed with ready-made fertilizers and humus. Raw potatoes perfectly feed the young bush. It must be passed through a meat grinder or grated on a coarse grater and added to the soil during the flowering period and in the fall. An additional effect is given by watering the bushes with tincture on potato peels. Potatoes are rich in starch, which for currants is like a dessert. From it, the berries become large, the size of a cherry.As a fertilizer, you can add half a liter jar of ash to the bush.
Caring for currants is not only pruning, top dressing and watering. Like any fruit crop, she loves when the ground around the bush is soft and weed-free. To do this, the soil must be regularly loosened and weeded.
Don't forget to mulch. This is a way to protect the soil around the bush with the help of organic and inorganic materials: sawdust, peat, straw, textiles. Mulch protects the soil from evaporation of moisture, and the roots from hypothermia.
Finally, currants need to be protected from frost. To do this, young bushes are wrapped with paper or film, they make a smoke screen next to the plant.
Taken together, blackcurrant care procedures do not take much time, but provide a good harvest of berries and a supply of vitamins for the whole year.
