How to propagate roses
The editor introduces to you how to propagate roses and the related introduction of the propagation methods and timing of green plants and flowers, let's take a look together!
Roses have strong adaptability and are widely distributed in 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 ways to propagate roses, but the most commonly used method is cutting. Depending on the position of the cutting, it is divided into new bud cutting, young shoot cutting, and hard shoot cutting. Let's learn about these methods 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 sprouted and have strong vitality, making it easier to root and sprout after cutting.
2. Cutting Selection: Choose strong and plump new buds, remove them and clean them, then 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 surrounding soil to ensure the plant does not fall over.
4. Subsequent Maintenance: After cutting, water thoroughly and cover with a layer of plastic film to create a humid environment. Open for ventilation morning and evening, and after 15 days, the roots can grow, and the film can be removed after 20 days, preparing for transplantation.

II. Young Shoot Cutting
1. Cutting Time: Young shoot cutting of roses is usually done in two periods, one in spring (April to May) and one in autumn (September to October). The climate during these periods is relatively warm, resulting in a higher survival rate. High temperature and humidity in summer can easily cause the wound to rot, preventing rooting and sprouting.
2. Cutting Selection: Choose healthy 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. When the branches become sturdy, you can cut them. The length of the cut is 10 centimeters, retaining two compound leaves and small leaves, and removing the rest.
3. Cutting Process: Use a mixture of decomposed leaf soil and coarse sand for the potting soil. Dip the lower part of the cut branch in rooting powder and insert it into the potting soil, about two-thirds deep, ensuring 2-3 buds are exposed.
4. Subsequent Maintenance: After cutting, water thoroughly and cover the potting soil well. If new buds grow and the old leaves do not fall off, it means the cutting has succeeded.
III. Hard Shoot Cutting
1. Cutting Time: The cutting time for hard shoots is chosen at the intersection of winter and spring when the temperature is still relatively cold. Although the cutting will not root immediately, it has a longer preparation time.
2. Cutting Selection: Cut a sturdy hard shoot, removing the lower leaves, leaving 2-3 leaves to prevent the leaves from rotting in the soil, causing bacteria to grow and affecting root growth.
3. Cutting Maintenance: Insert the branch into the sand, water thoroughly, then set up a frame, cover with a layer of film, and place it in a sunny location to receive light. When the temperature gradually rises, the film can be removed, and when the leaves turn green, it can be transplanted.
