Roses have a strong adaptability and are widely distributed throughout China. They come in many varieties with rich flower shapes and colors. The blooming period is long, from August to April of the following year.
There are many methods to propagate roses, but the most commonly used is cutting. Depending on the location of the cutting, it is divided into new bud cutting, tender stem cutting, and hard stem cutting. Let's learn about them together.
I. New Bud Cutting
1. Cutting Time: The cutting time for new rose buds is generally in spring when the new buds have just emerged and have strong vitality, making it easier to take root and sprout after cutting.
2. Cutting Selection: Choose sturdy new buds with full芽 heads, remove them, wash them clean, and set them aside for later use. If the new buds are weak, the survival rate after cutting will be low, and even if they survive, it will affect subsequent growth.
3. Cutting Process: Use simple soil such as sand, vermiculite, or perlite for rose cutting. First, make a hole in the soil surface with a stick, then insert the new bud into the hole, about one-third deep, and press the soil around it to ensure the plant does not fall over.
4. Subsequent Maintenance: After cutting, water thoroughly and cover with a plastic film to create a humid environment. Ventilate twice a day, morning and evening. After 15 days, the roots can grow, and after 20 days, the film can be removed, and it is ready to be transplanted.

II. Tender Stem Cutting
1. Cutting Time: Tender stem cuttings are done in two periods, one in spring (April to May) and the other in autumn (September to October). The climate during these periods is relatively warm, resulting in a higher survival rate. High temperatures and humidity in summer can easily lead to wound rot, preventing rooting and sprouting.
2. Cutting Selection: Choose strong branches from the current year that are free from diseases and pests. After the flowering period, remove the flowers and old leaves to accumulate nutrients. Once the branches become sturdy, they can be cut. The length of the cut is 10 centimeters, retaining two compound leaves and small leaves, and the rest are removed.
3. Cutting Process: Mix potting soil with decomposed leaf mold and coarse sand. Dip the lower part of the cut branch in rooting powder and insert it into the potting soil, about two-thirds deep, ensuring that 2-3 buds are exposed.
4. Subsequent Maintenance: After cutting, water sufficiently and cover the potting soil well. If new buds grow and the old leaves do not fall off, it indicates that the cutting has succeeded.
III. Hard Stem Cutting
1. Cutting Time: The cutting time for hard stems is chosen at the intersection of winter and spring when the temperature is still relatively cold. Although the cuttings will not root immediately, there is a longer preparation time.
2. Cutting Selection: Cut a sturdy hard stem and remove the lower leaves, retaining 2-3 leaves to prevent leaf rot in the soil, which can cause bacterial growth and affect root development.
3. Cutting Maintenance: Insert the stem into the sand, water thoroughly, set up a shelf, cover with a film, and place it in a sunny location. When the temperature gradually rises, the film can be removed, and when the leaves turn green, it can be transplanted.
