Description of currant breeding methods
The problem of propagation of the currant tree is very serious. Recently, more and more diseases have been formed that can destroy the culture. In addition, all kinds of harmful insects have also become active and seek to harm any bush with a berry. To prevent the culture from being destroyed, gardeners are increasingly breeding it. This allows you to strengthen the seedlings and grow a healthy tree.
Ways
You can grow and propagate currants in different ways. The breeding process is not very laborious, but it must be carried out carefully and carefully. Very often, gardeners make mistakes already in the early stages of breeding. To prevent this from happening, there are detailed instructions for each method of propagation of blackcurrant.
cuttings
Cuttings offer several methods of propagation, each of which is very effective:
- reproduction with the help of lignified cuttings;
- propagation using green cuttings;
- propagation by apical cuttings.
Propagate currants using lignified cuttings effectively and efficiently. This method allows you to get a lot of large and juicy berries from one young branch. Cuttings are harvested in the spring and autumn seasons. Reproduction in the spring takes place in conjunction with cutting bushes.Cuttings can only be cut from a young and healthy shoot. Branches with a diameter of nine millimeters and a length of twenty-five or thirty centimeters are suitable for cutting.
Branches should be saturated with healthy and intact buds. Branches must be cut very carefully. To cut, you will need a sharply sharpened knife or secateurs. Incisions are made above the kidneys, with a distance of one centimeter. It is also required to completely cut off non-lignified tops. It is required to make an incision in an oblique direction, cutting off all the parts under the lower kidneys. The essence of breeding currant culture with cuttings is the formation of roots. They appear in place among the cutting nodes and kidneys.
In autumn, it is necessary to prepare a special hole where currants will be planted. Fertile soil, rotted manure and compost are poured into this pit. You can start planting cuttings in early spring. This is done according to a certain scheme.
- First of all, the cuttings are planted to a depth of twenty centimeters. At the same time, two or three kidneys remain above the ground.
- It is important to leave a distance of at least fifteen centimeters between seedlings.
- Before starting the planting process, the soil must be well dug up and loosened. In addition, it must be moisturized. Moist soil activates the development of the root system of the tree.
- Next comes soil mulching. For this process, humus or peat is used. For mulching, the mentioned substances are poured into the ground with a thickness of five centimeters. Such top dressing will not only nourish the plant, but also retain moisture in the ground.
- To retain moisture and protect young cuttings from insect invasion, they can be covered with a dark film.For better monitoring of the process of plant reproduction and its growth, a hole is cut in the film above the seeds.
The black currant variety is bred in a similar way. As for the red species, it is recommended to plant it in early October. Reproduction of the plant at a later date will lead to the loss of half the crop.
If seedlings are sown at the end of the summer season, this will only improve the yield. When planting during this period, gardeners will receive fully formed bushes with berries.
Another type of cutting propagation is apical cuttings. Apical cuttings represent the top of fresh and annual shoots. Such cultivation of berries is quite difficult and costly. In order for reproduction to be successful, it will be necessary to prepare the soil and special equipment before planting. The work of the technique is to create moisture in the territory of the future sowing. Humidity must be present both in the air and in the soil. The humidity index for soil is eighty percent, and for air - ninety percent.
In order to moisten the soil, it is better to use a mixture of peat and clean river sand. These elements for the mixture are taken in equal proportions. Before placing the mixture, fertilizer is first laid out in the pit. Peat humus or sod-humus soil can act as top dressing. As soon as the fertilizer has been laid out in a thick layer of four centimeters, the prepared mixture is poured out.
The whole breeding process takes place in several stages.
- The first step is to prepare the material. Currant petioles are prepared during the period when year-old shoots acquire the necessary flexibility. This process lasts from the beginning of June until the second half of the month.
- Then the selected branches are cut. It is better to cut branches early. In cut branches, it is important to keep the flesh moist until a new planting. It is recommended to cut branches twelve centimeters long.
- It is better to plant cuttings in a greenhouse or greenhouse. There, for new seedlings, the optimum temperature is set. It is important to constantly provide moisture in the air and soil. Under the right conditions, root sprouts will be noticeable in a few weeks.
- The final stage of reproduction is care. As for watering, the plant requires a lot of water, so you will have to water it often. Both the soil in which the cuttings were buried and the shrub itself are watered. When the roots begin to sprout, the frequency of watering should be reduced. At this stage of the growing season, irrigation should be carried out with a large volume of water. At this point, it is also important to ventilate the seedlings. Active vegetation begins a month after the seedlings were planted. During the growth period, do not forget to feed the plants.
For top dressing use liquid fertilizer. Fertilize the plant is required once every three weeks.
The last method of breeding by cuttings is to plant non-lignified green branches. The breeding process is divided into several stages.
- The preparation of planting material, as in other methods, is the first step. It is recommended to look for suitable cuttings on a rainy and windy day. A strong wind will show the most flexible branches. It is better to choose branches of medium size. Fifteen centimeters will be enough. In addition, there should be at least four leaves on the branch.
- Before starting planting activities, the branches must be insisted in a special solution "Heterouksin".This butyric acid is considered the best growth stimulant. Planting materials are insisted during the day.
- Twigs are allowed to be planted only in greenhouse or greenhouse conditions. In dug holes filled with peat, sifted sand and ripened compost, cuttings are planted four centimeters deep. The cuttings must be covered with a plastic or glass bottle.
- Spraying cuttings is required to be carried out as often as possible. In addition to watering, shoots should be moistened daily.
- The young plant does not like the sun, so at the beginning of the growing season it is hidden from the sun's rays.
- The twigs take root in a few weeks. When this happens, the amount of watering is reduced. Instead, active fertilizing of the shrub with additives containing nitrogen begins. After a month, the seedlings become stronger and already begin to require more light. Therefore, it is necessary to remove the used plastic or glass container.
layering
The method of propagation by layering is used to breed many varieties of plants. This method has an important advantage, due to which it is so popular. When planting a crop, by layering, the probability that the seedlings will take root is one hundred percent. The essence of the method boils down to the spring instillation of several layers prepared since the summer. These layerings are taken from the main tree.
In order for the plant to take root better, it must be properly planted. First of all, pits fifteen centimeters deep are dug, into which shoots will then be planted. Holes are dug according to the pattern of rays that extend from the main shrub. These pits are carefully sprinkled with soil and soaked humus, peat and compost.All these powders are mixed in equal proportions.
Layers must be pinned with wire. To do this, the wire is bent in the shape of the letter "V" and sprinkled with earth. As soon as the young shoots begin to take root and germinate, the wooden pieces are removed. By mid-October, young cuttings will begin to take root. As soon as this happens, they are separated from the main tree. Propagation of blackcurrant culture in this way is carried out throughout the year. By the spring of next year, it is allowed to transplant layers to a permanent place of growth. As for the white and red varieties, their ripening period takes three years.
Before planting layering, it is required to carefully loosen the soil around the planting hole. In addition, nutrients must be added to the hole, and then watered. Currant cutting propagation is carried out in three ways:
- horizontal;
- vertical;
- arcuate.
The horizontal method is very popular. All procedures are carried out before the appearance of the first foliage. The most productive bush is selected. The soil before planting must first be loosened and fertilized well. In addition, the soil must be moist. First of all, last year's shoots bend down. After that, they are sprinkled twice with soil. The first powder is made when the plant grows up to ten centimeters, and the second when it grows up to fifteen centimeters. At the end, the seedlings are dug up and separated by secateurs.
The vertical layering method is used to breed red currant varieties. It involves cutting off all the branches of the shrub. From the remaining lower branches, active growth begins.When the shoot grows up to twenty-five centimeters, the soil is loosened and the bush is hilled.
By dividing the bush
Propagation of currants by dividing the shrub is a rather difficult task. However, this method is fast and does not require additional steps to improve the rooting of seedlings. Professional gardeners advise growing a plant using this method in cases where you need to quickly get a large number of berries. To breed a berry in this way, the currant tree must be cut. To do this, you need a saw or a sharp pruner. Shrubs are divided in such a way that each of them has a sufficient number of developing branches and roots. Unfortunately, the likelihood that the divided parts will take root is very small compared to cuttings.
It is possible to carry out the division of shrubs in the autumn and spring. This method is intended for transplanting an old currant bush into a new territory. To do this, you need to carefully dig up the tree along with the roots and free the roots from the soil. It is allowed to divide the bush into two, three or four parts. The number of divisions depends on the size of the mother bush.
To understand how many parts a tree can be divided into, you need to carry out the following procedure. The first step is to move the bush and bring the root system and branches into activity. According to the vibration emanating from the bush, it will be possible to understand where cuts can be made in order to propagate currants.
Before carrying out this procedure, it will be necessary to free the shrub from dried roots and shorten the young shoots to thirty centimeters. The resulting parts should be planted in holes with fertile soil and dug.Then the planted bushes need to be watered abundantly. Fruiting of such trees begins a year after planting. This is due to the fact that bushes that are weak after damage take time to recover.
seeds
Professional gardeners do not recommend growing blackcurrants by seed. Scientists are constantly breeding berry seeds. Therefore, the resulting hybrid seeds are unstable in many botanical characteristics. This applies to both taste and size of the berries. Often the size of the berries deviates not always for the better. Gardeners claim that the resulting seeds do not have the qualities of a mother plant. However, you can experiment with them and get new berry configurations.
Seeds can be bought or harvested naturally. This is done according to the following scheme:
- during the fruiting period, you should examine the currant tree and collect the largest and strongest fruits from it;
- then the collected fruits are thoroughly washed under running water and soaked in it for some time;
- washed seeds must be laid on a paper towel and dried well, this will take several days;
- dried seeds are harvested before the summer season.
This completes the process of natural seed production. Blackcurrant planting begins in early spring. First of all, planting material needs to be prepared for sowing and disinfected. To do this, seedlings are soaked in a weak infusion obtained after diluting potassium permanganate in water. Seeds should settle for twenty minutes. It is better to plant seeds in a wooden box, which was previously filled with fertile soil.Once the seeds have been planted, they need to be covered with another layer of soil, watered and then covered with a box. You can also use film or glass. The fixed box is placed in a dark place.
It is important to regularly wipe the cover material (film or glass) from escaping condensates and moisten it by spraying. As soon as the first shoots appear, the coating is removed. The box is transferred from a dark place to a more lit one. It is necessary to create favorable temperature conditions in the room with the box. When the cuttings grow fifteen centimeters long, they dive into different pots. With the onset of stable warm weather, usually the second half of May, young shoots are transplanted to the garden plot.
Ten days before planting currant sprouts must be hardened. To do this, a draft is made in the room with pots. To plant currants in the garden, small holes are dug in the area forty by forty centimeters in size. Pits are made on the sunny side of the site. They are located in the same row, with a distance between them of about a meter. After the sprouts have been planted, they are carefully watered.
It is important to irrigate until the seeds take root and before active growth begins. When the active flowering of shrubs begins, it is recommended to gently shake them. This is done so that the tree self-pollinates. Due to active self-pollination, the number of ovaries and berries increases.
Technology and timing of harvesting cuttings
The black variety is the most undemanding in the currant berry. Propagation of this plant and its subsequent care is easy and inexpensive. In order to breed a tree at home, you will need an actively fruiting bush.It will become a mother tree, it is from it that reproduction will begin. Pencil-thick annual shoots are cut off from such a bush. Also, the quality of the branches depends on the method of reproduction. Green cuttings require half-lignified branches. For all other methods, a completely lignified shoot is suitable.
Cuttings must be prepared in advance. The procurement scheme depends on the procurement period.
spring
For spring cuttings, last year's shoots are used. The size of the shoots should be twenty centimeters in length and half a centimeter in diameter. Cutting branches is allowed to be carried out above the active buds by one and a half centimeters. It is better to take cuttings from seedlings prepared in winter. After the cut, the seedlings are prepared, put in a box and covered with snow. You can start planting these seedlings when the soil at a depth of fifteen centimeters warms up to seven degrees.
Summer
Summer is considered the best season for preparing cuttings. You can start all procedures in mid-June, but no later than the first half of July. This interval is the stage of active germination of the currant bush. Cuttings are recommended from well-developed young shoots. The branches must be cut with a pruner, leaving fifteen centimeters. Before this, the secateurs must be well disinfected with boiling water.
Cut branches should have at least three leaves. The lower leaves are removed, as are the cuttings, and the upper ones are left so that they do not allow the water to evaporate. Cuttings are planted immediately.
autumn
Despite the fact that summer is the best season for harvesting cuttings, they prefer to propagate currants in the fall.This is due to the fact that in autumn fruiting is no longer so active, and therefore it is possible to disturb the tree to harvest seedlings. Black currant ends the flowering period late, so cuttings are carried out at a later date, approximately in mid-October.
Seedlings prepared in autumn can be rooted already in early spring, when the first heat comes. At this time, the root system is actively developing before the first buds bloom.
How to store planting material?
Often, gardeners begin to harvest cuttings in late autumn or winter. Since it is recommended to refrain from planting trees in cold temperatures, cuttings must be properly stored until spring. You can store cuttings in two ways.
- paraffin storage. To do this, melt the paraffin. Pre-cut cuttings are placed in molten paraffin. Then they are wrapped with cling film or a plastic bag. Wax may be used instead of paraffin. Canned cuttings are hidden in the basement. At times, it is required to inspect conservation in order to prevent rotting of the cuttings. If, nevertheless, rot appeared on some branches, then they need to be disposed of, and the remaining healthy branches are transferred to another dry room. Also, to avoid rot, you need to ventilate the room.
- storage in the substrate. For this method, you will need plastic pots or a cut plastic bottle. The volume of the container must be at least five hundred milliliters. Drainage is placed at the bottom of the tank. Expanded clay can play the role of drainage. Next, specialized soil for flowers is poured, which was previously mixed with peat or sand. Chopped cuttings are buried in the backfilled soil.For the entire period of storage, it is required to constantly spray the cuttings. The daily rate of spraying is four times.
Tips from experienced gardeners
Experienced gardeners are advised to choose the bush breeding method for those who need to grow new plants in the near future. Reproduction of blackcurrant by layering will take one year, and propagation of the red variety will take at least three years.
In order for the soil to be saturated with useful minerals, it is recommended to mulch it. In addition, adding peat mixed with river sand to the soil will also improve the fertility of the berry bush.
