How to propagate roses by cutting
A brief knowledge of life, about how to propagate roses by cutting and the methods and timing of rose cutting for green plant maintenance, the specific content is as follows:
Roses have a strong adaptability and are widely distributed in China. They come in many varieties with rich flower shapes and colors. The flowering period is long, from August to April of the following year.
There are many ways to propagate roses, but the most commonly used is the cutting method. Depending on the location of the cutting, it is divided into new shoot cutting, tender shoot cutting, and hard shoot cutting. Let's learn about them together.
I. New Shoot Cutting
1. Cutting Time: The cutting time for new rose shoots is generally in spring when the new shoots have just grown and have vigorous vitality, making it easier to root and sprout after cutting.
2. Cutting Selection: Choose strong and plump new shoots, remove them and wash them clean, then set them aside for later use. If the new shoots 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 for rose cutting, such as sand, vermiculite, or perlite. First, make a hole in the soil surface with a stick, then insert the new shoot 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 plastic film to create a humid environment. Open the ventilation morning and evening, and after 15 days, they can root, and the film can be removed after 20 days, preparing for transplantation.

II. Tender Shoot Cutting
1. Cutting Time: Tender shoot cutting of roses is done in two periods, one in April to May in spring and the other in September to October in autumn. The climate during these periods is relatively warm, resulting in a higher survival rate. High temperature and humidity in summer can easily cause wound rot, preventing rooting and sprouting.
2. Cutting Selection: Choose healthy branches from the current year that are free from diseases and pests. Generally, after the flowering period, remove the flowers and old leaves to accumulate nutrients. When the branches become sturdy, they can be cut. The length of the cut is 10 centimeters, retaining two compound leaves and small leaves, 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 branches in rooting powder and insert them into the potting soil, about two-thirds deep, ensuring 2-3 buds are exposed.
4. Subsequent Maintenance: After cutting, water sufficiently and cover the potting soil well. If new shoots grow and old leaves do not fall off, it indicates successful cutting.
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 cuttings will not root immediately, there is a longer preparation time.
2. Cutting Selection: Cut a strong hard shoot, remove the lower leaves, retaining 2-3, to prevent leaf rot in the soil, which can cause bacterial growth and affect root development.
3. Cutting Maintenance: Insert the branches into sand, water thoroughly, then set up a frame, cover with a layer of film, and place in a sunny spot for sunlight. When the temperature gradually rises, remove the film, and when the leaves turn green, they can be transplanted.
