Planting and care of repairing raspberries, as well as plant propagation, are very relevant topics for both experienced and novice gardeners in early spring. Despite its unpretentiousness, repair raspberries, due to their botanical characteristics, need special care. In addition, the peculiarity of the repairing varieties is the relative complexity of the reproduction 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 with the aim of replacing already prolific shoots. Excessive offspring should be removed or used for sedimentation.
The technology for performing this method of reproduction is simple even for beginner 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. Transplanted mature and well-developed raspberry seedlings to a permanent place can be both in autumn and early spring.
The cultivation of remont raspberries with the use of well-developed green offspring, or layering, involves the preparation of planting material in the summer period 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.

Reproduction by root offspring and layering allows you to get the most strong and healthy plants.
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, technology must be strictly observed.
Prepared seeds should be sown to a depth of not more than 5 mm and sprinkled with light soil. 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 open ground.
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.
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.
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.
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 shredding of the berry 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.
