The bush is divided at the end of April before the buds open.
For propagation, mature, overgrown specimens with a strong root system are selected.
The rose is dug up, trying to preserve all underground shoots. Using a sharp pruner, the bush is divided into several parts, each of them should have a root and several shoots. Long or damaged shoots are cut off from the underground part. The shoots are shortened, leaving 3 living buds. The cut areas are treated with garden varnish, and the root is dipped into a clay mash. The young plant is planted in open ground.

The rooting procedure is carried out in the spring until the buds open.
The area around the rose bush is fertilized and dug up. Select a flexible, mature shoot and make a notch on it around the circumference in the place where it will come into contact with the soil. The shoot is bent to the ground and secured with staples. The cut site is lightly sprinkled with soil mixed with humus.
