Planting and care for remontant raspberries, as well as plant propagation, are very relevant topics for both experienced and novice gardeners in early spring. Despite the unpretentiousness, repair raspberries, due to their botanical characteristics, need special care. In addition, the peculiarity of the repairing varieties is the relative complexity of propagation of such raspberries in the traditional and familiar ways for gardeners.

Propagation by root offspring and layering

This method of propagation of raspberry of repairing varieties is one of the simplest and is based on the use of root offspring, which arise in sufficient quantity around an adult plant, as planting material. Root offspring are formed in the rows and rows of raspberry, and some of them are recommended to be left in the rows in order to replace the already fertilized shoots. Excessive offspring should be removed or used for sedimentation.

The technology for performing this method of reproduction is simple even for novice gardeners:

  • in the process of digging up root offspring, the shoot should be cut to a height of 30-35 cm;
  • it is preferable to select for propagation the most developed and powerful annual shoots, the thickness of which at the base is about 8-10 mm;
  • the root system should also be sufficiently developed, and the roots are cut to a length of 15-20 cm.

The dug root shoots are transplanted to the school, where the process of growing plants is carried out. For the school, it is necessary to allocate a site with fertile soil. Strong and well-developed raspberry seedlings can be transplanted to a permanent place both in autumn and early spring.

The cultivation of remont raspberries using well-developed green offspring, or layering, involves the preparation of planting material in the summer at a shoot height of not more than 8-10 cm. Layers are transplanted with a lump of land to a separate place, after which they are irrigated and mulched.

How to propagate repair raspberries

Propagation by root offspring and layering allows you to get the most strong and healthy plants.

Seed propagation

Seed propagation of raspberries is used only for breeding purposes. Harvesting of seed material should be made from the most valuable varieties, which are characterized by early fruiting, large-fruited, high productivity, as well as good resistance to diseases and pests. In addition, in order to propagate raspberries in this way, the technology should be strictly observed.

StageTechnology
Seed harvestingThe largest berries that are early ripened on the bush are used. They must be placed in a bag of nylon, knead in water and remove the flesh
Seed storageSeeds are stored in a refrigerator at a temperature of + 1 to + 3 ° C
Seed stratificationSeeds are soaked in water at room temperature, which should be changed daily for five days. Then the seeds are mixed with clean river sand and placed in the refrigerator, where they are stored for a month and a half at a temperature of +2 to + 4 ° С
Seed scarificationSeeds are washed and soaked for four days in a 1% solution of calcium hypochlorite and a 0.5% solution of calcium oxide hydrate. After that, the seeds are washed in running water and sown

Prepared seeds need to be sown to a depth of not more than 5 mm and sprinkled with light soil. Required to keep the soil moist. After the formation of a pair of true leaves, a pick is carried out. In the early spring of next year, grown seedlings are planted in a permanent place in the open ground.

Microclonal method

Microclonal, or meristemal, propagation contributes to the production of plants that inherit the full range of traits inherent in the parent raspberry variety. The method is widely used by specialists of Russian research institutes and modern breeding centers.

StageTechnology
IntroductorySeparation of meristemic tissues and placing them on a special nutrient medium, followed by aging for a month in light conditions up to 14 hours a day
BreedingAfter a month and a half, the microscopic cuttings of the plant are divided into several parts, which are germinated in vitro for a month
Rooting and adaptationAfter the formation of the root system, plants are transplanted into peat pots, where rooting takes place and adaptation to growing conditions begins
Growing upIt is carried out in compliance with agricultural technology, which is required for this berry culture, and prepares plants for transplanting to a permanent place

Raspberry Cuttings

This highly productive agricultural technique is very convenient when growing remont raspberries, which are well propagated by cuttings in several passes. NThe best quality are green cuttings, which are formed in the spring and in the first decade of summer.

StageTechnology
BilletCuttings should have a well-formed rosette of leaves and have a height of not more than 3-5 cm. The cuttings need to be cut deep enough to obtain a light etiolated zone
TreatmentBefore planting in the greenhouse, it is advisable to update the cutting site, and then sprinkle it densely with crushed charcoal
Rooting and adaptationIt is carried out in greenhouses or greenhouses. Landing is carried out according to the scheme 5 x 10 cm, the recess is standard. The rooting soil should be enriched with peat and sand. It is necessary to carry out timely watering and ventilation. Before planting in a permanent place, seedlings need to be hardened
PlantingThe best way to plant grown raspberry seedlings is to plant plants in narrow rows in any direction. After planting, it is advisable to mulch the soil with humus.

After landing care

The concept of "remont raspberry" unites a group of varieties of this berry culture, which is distinguished by the ability to carry fruit not only on two-year, but also on annual shoots. The care of young remont raspberries in the first two years is standard and is based on the implementation of basic agricultural activities.

EventTechnology
Top dressingAfter rooting the plants, full fertilizers with the composition N-P-K in the ratio of 10: 10: 10 or special fertilizers for fruit and berry bushes are applied
WateringIt is especially important not to allow the soil to dry out in raspberries during the first month after planting. The depth of soil moisture should be approximately 40-50 cm
Weeding and cultivatingWeak raspberry seedlings react very painfully to the presence of weeds. To reduce the number of weeds and loosening, it is recommended to mulch the soil

Proper planting and proper care are a guarantee of long and abundant fruiting of raspberries. It should be remembered that after five years of fruiting a plant, a decrease in yield and berry chopping can be observed. It is very important to timely rejuvenate raspberries. For this purpose, the central part of the plant is cut and removed along with the old rhizome. The remaining root system forms rapidly developing powerful shoots, as a result of which raspberry productivity increases, and the quality characteristics of berries increase significantly.
