How to propagate remontant raspberries: terms for harvesting cuttings, methods and tips for gardeners
Anonim

Remontant raspberries are characterized by long fruiting during the growing season. It is not surprising why many gardeners are wondering how to properly propagate remontant raspberries. When growing any crop, every summer resident wants to get as much harvest as possible. That is why such hybrids quickly became popular among gardeners.

When to harvest planting material

Before propagating raspberries, you should decide on the timing of the harvesting of planting material. Choosing the period when you need to harvest raspberries should be based on the timing of planting.For propagation by cuttings, seedlings are harvested from spring. Most often, raspberries are bred in the spring, so it is recommended to choose planting material at this time.

When planting in the fall, the preparation of seedlings begins in the summer. When propagating in summer, seedlings are also prepared in spring.

Methods and technology of propagation of remontant raspberries

There are several ways to breed remontant raspberries. If you follow all the rules of agricultural technology when planting, you will be able to quickly grow raspberry bushes that will bear fruit abundantly.

Nettle method

Remontant raspberries are propagated using the "nettle" method. This method is used in the spring. When raspberries begin to sprout, they look more like nettles. When planting, the shoots must be at least 10 cm in height and with two full leaves.

Planting raspberries using the "nettle" method:

  • Remove the soil from the base of the shoot.
  • Cut off the shoot along with the white underground part of the stem (it can be 3-5 cm long).
  • Cut bushes are treated with growth-activating drugs.
  • For planting, prepare a loose substrate (mix peat and sand).
  • Plant the seedling, all the white underground part and part of the green shoot must remain underground.
  • Pour plenty of bushes with warm water.
  • Cover the bushes with bottles to create a greenhouse effect.

In a few weeks, the seedlings should take root. As soon as they get stronger, raspberries are transplanted to a permanent place on the street. Planting takes place towards the end of June.

Green cuttings

Propagating remontant raspberries with cuttings is quite simple. For this method, he althy young shoots are taken without signs of disease and traces of insects. It is best to choose a cloudy day for preparing cuttings for planting.

Propagation of remontant raspberry varieties with green cuttings in summer:

  • Cut green young sprouts with a sharp pruner (it is recommended to cut closer to the base of the rhizome).
  • Place in water with a growth stimulator added.
  • After a while, roots should appear on the cuttings.
  • When the roots are large enough, the cuttings are transplanted into fertile, moist soil.

With proper care, the stalk will very quickly begin to grow deciduous mass and begin to bear fruit. After planting in open ground, they are watered abundantly. Also, it will not be superfluous to apply complex mineral fertilizers.

Rooting with lignified cuttings

Planting with lignified cuttings is done in autumn, in September-October. As planting material, annual shoots are used, which have already become woody.

Cuttings of remontant raspberry varieties in autumn:

  • Cut cuttings about 20 cm long.
  • Remove all leaves, new buds have already appeared on the cuttings, and the foliage will only take nutrients.
  • Dig up the soil, dig holes.
  • Place the cuttings in the holes so that only two buds remain on the surface.
  • Cover with spruce branches or agrofibre.
  • In autumn, the shoots will take root, and in the spring they will begin to grow actively.

Also, propagation by lignified cuttings is carried out in the spring. To do this, the stems are cut in the same way as in the first method. Then they are placed in boxes with wet sand and left in the refrigerator. In March, the cuttings are rooted at home, and when the heat comes, they are planted.

Dividing the bush

The division of the bush is used most often in the cultivation of most crops. This method is suitable for plant propagation in the autumn. September-October is considered the optimal transplant time, when the raspberries finish fruiting.

2-3-year-old bushes are suitable for propagation by dividing the bush. The bush is cut into several parts with a sharp shovel and dug up. Then each part is transplanted to a new place. After planting, the soil around the raspberries is mulched so that they survive the winter frosts well and do not die.

Propagation by root cuttings from the mother bush

It is easiest to propagate remontant raspberries from the mother bush. Root cuttings are suitable for propagation in this way. The root cutting is a part of the rhizome with a lateral branch. For propagation, roots with a thickness of more than 2 mm are used.

Root cuttings are separated from the mother bush in spring:

  • The cuttings are cut off from the mother bush after it is covered with leaves.
  • Then planted in holes about 5 cm deep.
  • After that, the holes are covered with soil, lightly tamped and watered abundantly with warm water.
  • After planting, it is recommended to cover the cuttings with foil. With this measure, you can create a greenhouse effect, and the bushes will grow faster.

When green leaves appear, the film is removed. But the seedlings themselves are recommended to be sheltered from bright sunlight and wind. As soon as the raspberries get stronger, the protection is removed.

Stem cuttings

Remontant raspberries can be propagated by stem cuttings. According to technology, the method is no different from other methods of growing raspberries by cuttings.

Propagate with horizontal layering

When grown horizontally, annual shoots are used. This type of breeding is carried out in the spring. A groove 10-15 cm deep is dug next to the bush.

The shoots are bent to the ground and dug in with earth. They need to be fixed in order to root. As soon as the stem begins to germinate and grow deciduous mass, it is separated from the mother bush. In this case, there may be several seedlings. This breeding method is carried out in the summer.

Sprouting from seeds

Growing with seeds is not very popular among summer residents. This method is time-consuming, time-consuming and not the most effective. This method is preferred by breeders to breed new varieties.

How to get raspberry seeds:

  • To obtain the seed, the largest raspberries are harvested and juice is squeezed out of them.
  • Then pour the juice together with water into a container and filter through gauze. The procedure is repeated several times until the water is clear and the seeds remain at the bottom of the container.

Dry the seeds, put them in a paper envelope and put them in the refrigerator.

Before sowing raspberry seeds, stratification is carried out. To do this, the seeds are poured with water, the container is placed in the refrigerator for 24 hours. Then they are mixed with sand.Pour sand with planting material into nylon stockings and put it in the cellar. The bags themselves are covered with sawdust. Seeds are stored in the cellar for about 3 months.

Planting material is planted after the room temperature reaches +20 degrees. Seeds are planted in containers with fertile soil. To create a greenhouse effect, the containers are covered with cling film and placed on the southern windows.

Seedlings are transplanted into separate pots after they grow to a height of about 10 cm. When the weather is warm outside, they are planted in open ground.

Advice for beginner gardeners

In order for remontant raspberry varieties to take root faster after planting and give a rich harvest, you must follow the rules for caring for the bushes:

  • To make cuttings more active, before planting raspberries, the soil is fertilized with mineral and organic top dressings.
  • For the winter, planted bushes are covered with spruce branches or agrofibre.
  • It is recommended to plant raspberries in well-lit areas and in fertile soil.
  • When propagated by green cuttings, to accelerate the appearance of roots, the lower part of the cutting is treated with growth activators for crops.
  • It is undesirable to plant seedlings in a lowland, where water accumulates and stagnates in spring.
  • Young seedlings are regularly fed with mineral and organic fertilizers.
  • Only sharply sharpened secateurs are used to harvest cuttings for planting. Creases in places of cuts should not remain.

With proper care, raspberry cuttings will quickly take root in a new place, and the next year after planting they will begin to bear fruit.
