Roses have a strong adaptability and are widely distributed throughout our country. They come in many varieties, with rich flower shapes and colors. The blooming period is long, lasting from August to April of the following year.
There are many ways to propagate roses, but the most commonly used method is cuttage. Depending on the position chosen for cuttage, it is divided into new bud cuttage, tender shoot cuttage, and hard shoot cuttage. Let's learn about these methods together.
I. New Bud Cuttage
1. Cutting Time: The best time for new bud cuttage of roses is generally in the spring, when the new buds have just emerged and are full of vitality, making it easier for them to root and sprout after cuttage.
2. Cutting Selection: Choose robust new buds with full buds. After breaking them off, clean them and set them aside. If the new buds are weak, the survival rate after cuttage will be low, and even if they survive, it will affect subsequent growth.
3. Cuttage Process: Use simple soil for rose cuttage, such as sand, vermiculite, or perlite. First, make a hole in the soil surface with a stick, then insert the new bud into the hole, about one-third deep, and compact the surrounding soil to ensure the plant does not fall over.
4. Post-Cuttage Care: After cuttage, water thoroughly and cover with plastic film to create a humid environment. Open the ventilation twice a day, morning and evening. After 15 days, the roots will form, and after 20 days, the film can be removed, and the plant is ready for transplantation.

II. Tender Shoot Cuttage
1. Cutting Time: Tender shoot cuttage of roses is usually done in two periods, one in April to May in the spring, and the other in September to October in the autumn. These periods have warmer climates and higher survival rates. High temperature and humidity in the summer easily lead to rotting of the wounds, preventing rooting and sprouting.
2. Cutting Selection: Choose robust shoots of the current year that are free from diseases and pests. After flowering, remove the flowers and old leaves to accumulate nutrients. When the shoots become thick, they can be cut. The length of the cuttings should be 10 centimeters, retaining two compound leaves and small leaves, removing the rest.
3. Cuttage Process: Prepare potting soil with decomposed leaf mold and coarse sand. Dip the lower part of the cuttings in rooting powder and insert them into the potting soil, about two-thirds deep, ensuring 2-3 buds are exposed.
4. Post-Cuttage Care: After cuttage, water thoroughly and cover the potting soil well. If new buds appear and old leaves do not fall, it means the cuttage has been successful.
III. Hard Shoot Cuttage
1. Cutting Time: The best time for hard shoot cuttage is 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 robust hard shoot, removing the lower leaves, retaining only 2-3, to prevent rotting in the soil and the growth of bacteria that could affect root development.
3. Cuttage Care: Insert the shoot into the sand, water thoroughly, then set up a frame, cover with a film, and place it in a sunny spot to receive light. When the temperature gradually rises, remove the film, and when the leaves turn green, the plant can be transplanted.
