3. Add special fertilizers to the hole in advance.
4. To prevent moisture stagnation, a small layer of drainage material must be placed on the bottom of the pit.
5. Covering the seedling with earth, you need to leave the root collar 3-4 centimeters below the soil level.
6. Finally, water the planted plant with a moderate amount of water.

Plant care

Watering rules and humidity. Since the plant is located on the sunny side, it needs timely abundant watering, especially during the dry summer period. Water the bush with soft, slightly warm water up to 3 times a week.

Superphosphate is applied under a perennial during the period of bud development. A couple of weeks after flowering, fertilizing is carried out with mineral fertilizers.

Pruning and replanting

Another important point: in the first year of planting, it is recommended not to let the rose bloom by cutting off the buds, for its more luxuriant flowering next year and to prepare for the first wintering. You can leave a couple of inflorescences in the last month of flowering.

Having placed the cuttings in the soil about 2-3 centimeters deep, they are sprayed with water and covered with foil. It is necessary to water and air the planted cuttings every day. Approximately two to three weeks after the appearance of the callus, the cover is removed. After another two weeks, the root system will begin to develop. Sprouted bushes are left to winter in a greenhouse, and in spring they are transplanted into a front garden.
