Blackberry breeding rules and methods

Blackberry breeding rules and methods

When it comes to blackberries, summer, the forest thicket and the pleasant aroma of this wild berry immediately come to mind. But it turns out that it is not necessary to go to the forest for blackberries. It can be successfully grown in the country.

Timing

The cultivation of blackberries - a tasty, fragrant and healthy berry - has gained great popularity in recent years. There are quite a few arguments in favor of its cultivation: useful berries, it is undemanding in care and, in addition, it can be used as a living and very beautiful hedge.

The peculiarity of the blackberry is that it can grow for a long time (up to 10 years) in the same place and bring a large harvest. Another feature is that it is quite simple to propagate blackberries and you can plant them not only in spring and autumn, like other crops, but also in summer.

Autumn is the best time to breed it. During this period, the blackberry is at rest, and with the onset of cold weather, the stratification of the plant occurs in natural conditions. Seedlings adapt to the cold and gain stamina.

The timing of the autumn landing directly depends on the climate of the region. But such a condition must be observed - it must be planted no later than a month before the onset of the first frost.

In the spring, it is effective to plant seedlings or cuttings that have roots. Spring planting guarantees the rapid growth of blackberries, the development of a powerful root system and good survival. Planting in the spring also allows you to control the growth of blackberries and determine its viability.

A negative factor can be considered that with the onset of heat, soil moisture quickly disappears, which requires monitoring the condition of the soil under the bush and regular watering.

The timing of spring planting also depends on the climatic and weather conditions of each area. You can start disembarking only after the onset of heat (at a stable +15 degrees) and there is no threat of frost returning. The earth should warm up well by 10–15 cm.

Usually this time comes by the middle of spring, and the planting period lasts from the second decade of March to the first days of May, depending on the region.

If the spring is long and it is still cold in March, then the planting is postponed to a later date. But you need to have time to plant blackberries before the leaves begin to bloom on the seedlings.

Blackberries can also be propagated in summer. Most often during this period, reproduction is used with the help of layering, by dropping shoots, as well as transplanting young sprouts and dividing the blackberry bush into daughter shoots.

Reproduction methods

There are many ways to grow blackberries, and they depend on the season of their implementation.

cuttings

Cuttings can be carried out by both root and stem cuttings. An effective method is the cultivation of blackberries by root cuttings. It is held in November.

  1. The blackberry bush needs to be dug up, carefully release the roots and cut off the cuttings from them, and then bury the roots again.
  2. For cuttings, roots with a thickness of 0.3 to 1.5 mm are suitable. The length of the handle should be 6-9 cm.
  3. Fold the cuttings in a bag and store in a cold place (cellar, refrigerator) at a temperature not exceeding +5 degrees.
  4. Regularly once a week it is necessary to check the condition of the cuttings and ventilate them.
  5. In the last days of February, the cuttings should be placed in a container, covered with a 3 cm layer of earth and placed for germination on a windowsill or other warm and bright place.
  6. Soon the cuttings will sprout, and in April the grown seedlings can be planted in the ground.

If there is a need for a large number of seedlings, then they resort to cuttings from the stems. It is held in October, and it is done in a certain sequence.

  1. For cuttings, shoots of the current season are chosen and only those that have had time to stiffen.
  2. Their length should be about 40 cm.
  3. Cuttings need to be buried in the soil by 30–40 cm. They spend the winter in the soil.
  4. In the spring, in April, the cuttings are dug up and their ends are re-cut.
  5. After that, you need to spread the cuttings on the ground with a gap of 10–15 cm, and then bury them in the soil.
  6. To speed up their germination, it is recommended to make a small greenhouse of arcs and polyethylene.
  7. Periodically, it is necessary to water the cuttings and remove weeds.
  8. You can dig up cuttings after new blackberry shoots form on them and real leaves appear on the shoots ( 2-3 pcs.).
  9. The cuttings are divided into seedlings with young sprouts and transplanted into any container in order to root them well.
  10. You can plant young bushes in the ground when they grow new stems and young leaves.

layering

The method of reproduction by layering is best suited for climbing blackberries. This method allows you to breed it in the summer and grow many new bushes at once. It is held at the beginning of August and carried out in this way.

  1. Tilt one-year-old young shoot to the ground without separating it from the mother bush.
  2. Dig a ditch (about 20-30 cm deep), in which carefully place the shoot and cover it with earth.
  3. The tip and shoots on the shoot should remain on the ground, but they need to be cut back about 10 cm to stop growth.
  4. The soil needs to be compacted, the sprinkled shoot should be fixed with a heavy object so that it does not straighten.
  5. Then the landing site must be mulched and regularly maintain soil moisture.
  6. After about 1-2 months, young seedlings will take root, layering can be dug up. It is better to do this with a pitchfork so as not to damage the young roots.
  7. Each young seedling is cut off and planted in a separate place.

You can also dig in the shoot in the fall (at the end of September or the beginning of October), and the transplantation of rooted seedlings is carried out in the spring of next year.

Layering can also be done with tops. The apical method is the best option for breeding varieties of creeping and climbing blackberries. It is possible to carry out layering only in the last days of August or the first days of September. Before the onset of frost, the shoot will have time to take root, take root and take root.

In order to properly implement this method, one-year-old blackberry shoots one and a half meters long are used.

  1. The apical part of the shoot is buried in the soil to a depth of 10–15 cm.
  2. After about a month, young shoots appear at the tops and the root system is actively developing.
  3. The shoots must be covered for the winter with foliage or covering material.
  4. After wintering in the spring, young seedlings are dug up and planted in another place.

seeds

Blackberries are also propagated by seeds. Blackberry seeds are easy to obtain, but the germination process itself is inactive. For seeds, you need to choose only completely ripe berries. First they are dried and only then the seeds are selected. One berry contains a lot of seeds.

The procedure is the following.

  1. Soak the seeds and keep them in water for 2-3 days. It is recommended to use melt or rain water, as soaking in boiled tap water does not give good results.
  2. Then the seeds are placed in a mixture of white sand and peat in a ratio of 1: 3 and placed in a cool place (for example, in a refrigerator) for 1.5-2 months. This stratification procedure is necessary for seed hardening.
  3. After the seeds are sown in a container with soil, placing them at a distance of 3–4 cm. Planting depth should not exceed 8 mm.
  4. The optimum temperature for seed germination is +20 degrees.
  5. Seedlings should be watered as needed with settled boiled water.
  6. Sprouted sprouts can be transplanted into the ground when they have 3-4 true leaves.

It should be noted that with this method of reproduction, young seedlings do not retain maternal properties.

The division of the bush

There are varieties of garden blackberries that do not grow young shoots. Therefore, dividing the bush is the only way to propagate blackberries.

This method is carried out in the fall (September or October) before pruning the plant. The division is also done in a certain sequence.

  1. A few days (2-3) before dividing, you need to water the blackberry bushes well.
  2. Dig a groove around the bush, stepping back 30–40 cm from the basal neck. Roots that are on the other side of the groove must be chopped off with a shovel.
  3. Undermine the bush around the perimeter and carefully dig it out, being careful not to damage the roots.
  4. Shaking the bush, release the roots from the soil.
  5. Divide the roots into pieces and cut them off with a sharp garden knife. Each part of the bush should have young shoots (1-2) with roots.
  6. Remove old or damaged stems, cut off rotten roots, shorten the shoots, leaving 30 cm.Each of the remaining branches should have at least 2-3 shoots and at least one underground bud on the roots.
  7. These seedlings are planted in prepared pits located at a distance of up to 3 m from each other in a row. The row spacing should be approximately 2 m.

In the spring, blackberries can be propagated by offspring. Planting seedlings can only be taken from blackberry bushes that have been growing and bearing fruit for more than three years. Such a blackberry has a powerful, strong and underground root system that has grown underground, from which young shoots have sprouted - offspring.

It is advisable to plant the offspring early (until mid-summer), so that the young growth does not take away food from the mother bush.

They are carefully dug out of the soil along with a small section of the root system, chopping off the main root and, without shaking off a clod of soil, planted in the chosen place.

You can also propagate blackberries with a dormant bud. This method is quite lengthy, but effective.

  1. In mid-autumn (October), cut annual shoots into cuttings so that each has 2-3 buds. They must be placed in a cold place and stored until spring.
  2. In late February or early March, the cuttings should be placed in a container of water so that the upper kidney is in liquid.
  3. The container should be kept in a warm, bright place and water should be added regularly.
  4. After the appearance of a sprout and roots from a kidney, this part of the cutting is cut off and transplanted into a container with earth for further growth.
  5. In the same way, subsequent buds are placed on the handle, germinated and transplanted. Then the grown seedlings are transplanted into the ground.

The best way to propagate remontant blackberries is to propagate by root bud. It is also possible to use the methods of rooting the apex and horizontal layering.

A straight-growing blackberry - a blackberry tree - is propagated mainly by root offspring or cuttings from the roots.

Aftercare

To grow a blackberry and get a big harvest, you need to provide it with appropriate care. It consists in observing all the rules of agricultural technology: watering, loosening, weeding, fertilizing, timely pruning.

To facilitate harvesting, for climbing and creeping varieties of blackberries, it is recommended to install trellises, to which bushes are tied.

Blackberries require watering throughout the growing season. It is carried out regularly as needed. Watering is especially necessary during the ovary of fruits and the growth of shoots. For irrigation, it is recommended to use rainwater or water that has settled for 1-2 days. Blackberries stop watering only in October.

The blackberry also needs feeding. At the beginning of the growing season, nitrogen fertilizers (urea, ammonium nitrate) are applied in the amount of 20 g per square meter. m. and organic - about 4 kg per square meter. m. Every year you need to feed blackberries and potash fertilizers that do not contain chlorine. If organics were not used, then phosphorus fertilizers must be applied.

As necessary, weeds are removed and the earth is loosened to a depth of 10–12 cm between the rows. Under the blackberry bushes loosening the soil is done with a pitchfork about three times during the season. The depth of loosening is about 8 cm.

It is effective to mulch with straw, leaves or sawdust. This will allow less loosening and weeding. If manure or peat is used as mulch, it will also become an additional source of nutrition for plants.

Upright blackberry varieties require regular pruning and shortening of young shoots, which are about 1 m long.The tops of these shoots are cut off by 10 cm, and the grown side shoots begin to shorten when they reach a height of 50 cm.

Blackberries suffer from the same diseases as other berry bushes. The most common diseases are powdery mildew, rust, white and purple spots, gray rot. Preventive work will protect against infection. They consist in spraying blackberries with a 1% solution of Bordeaux liquid in the spring after the leaves bloom. And in the fall, after picking the berries, re-spraying is done.

In addition, it is necessary to carry out prevention from harmful insects that infect blackberries: ticks, weevil, raspberry moth, nutcracker. Processing in the spring after the leaves bloom, and in the fall after harvesting with Karbofos, Fitoverm, Actellik, will protect the shrub from damage by these pests.
