Propagation by offspring and root cuttings
May 23, 2018
Reproduction by the root offspring of
Raspberry and blackberry erect very well by one-year-old shoots, grown on root siblings. And over one summer they can per meter and more "crawl away" from the mother's bush. In autumn, the most powerful offspring, together with part of the root system of the bush, are excavated and transplanted to a prepared place. Formed in this way, new shrubs are well established.
Raspberry propagation by root cuttings is based on the good regenerating ability of its roots. Root cuttings harvested in the fall during the digging of saplings-offspring. Cuttings are cut into 2 mm thick and thicker roots cut into 15 cm lengths. They are planted obliquely into the grooves or slits of the
. • Raspberry sprouts with a kidney( 1, 2,3,4) can be used to plant the
10 cm deep with the top endup. A small number of cuttings are planted in greenhouses in grooves 5 cm deep, laying them horizontally back to back. Care for them is normal. By the autumn of next year, shoots with a good root system grow from the buds of the roots. The method is very effective.
Reproduction of "nettle", Vmae-June, young offspring, 8-15 cm high, are cut at the soil level, tied into bundles of 25 pieces.and immersed in the OD-percentage solution of heteroauxin for 16-17 hours. After this, the cuttings are planted in a greenhouse where, at high humidity, after three weeks, the cuttings become rooted. In the open ground they are transplanted after gradual hardening. By the autumn of them, saplings of standard size grow.
Green root offspring can be planted later, when they form their own root system. In the second half of summer, growing green shoots of raspberries are undermined, separated from the mother roots and, preferably with a coma
of the seedling-seed of raspberry
of the earth, is transplanted to a permanent place in the garden. The separation and planting of such plants is best done in cloudy and rainy weather. After 2 weeks, the seedlings start growing and, by the time of the excavation of the planting material, reach the standard dimensions.
