- In the spring, a shrub that has reached the age of three needs sanitary pruning. A rose bush is formed into a bowl, leaving five to seven buds on each branch. In the fall, pruning is carried out in order to remove diseased and damaged shoots, thinning out overgrown branches.
- In May, the stems are recommended to be treated with a solution of sodium humate to stimulate lateral branching.
- Top dressing is done seasonally: in the spring with nitrogen, in the summer with phosphorus and potassium. Regularly, especially before flowering, you need to make rotted manure.
- In summer, the plant is watered with warm water at the rate of 15-20 liters of water per bush twice a week. By the end of summer, watering is reduced, and in September it is stopped altogether.
- Throughout the growing season, you need to cut off faded buds. In August, leave a pair of flowers on each shoot for the formation of fruits. This is necessary so that the roses better winter and bloom profusely the next year.
- Cordes Diamond Rose Care also includes regular weed and pest control.
- In winter, the shoots are shortened by two-thirds and covered with spruce branches, humus or loose earth.
