Cuttings

Layers
The easiest way to propagate decorative viburnum Roseum is vertical and horizontal layering.
In the first case, the lower branches of the shrub are shortened to four buds, tilted to the ground and sprinkled with soil. In the spring they give young shoots. As soon as it reaches a height of 10 cm, it is again covered with soil. In autumn, seedlings of common viburnum Roseum are separated from mother plants and transplanted.
Horizontal layers are made from long branches. They are bent down, laid in a small trench, pinned and covered with earth. Twice during the season, layering is covered with fertile soil. In autumn, after rooting and formation of growth, young plants of the common viburnum Roseum are transplanted.
By dividing the bush
The method is convenient only if the plant is not very voluminous and can be easily dug up. The mother bush is carefully cut into several parts, the sections are disinfected and the roots are soaked in a growth stimulator for 2-3 hours. After that, “delenki” of the common viburnum Roseum are planted in compliance with all the rules.
