How to propagate roses through cutting to improve survival rate
An article on useful knowledge, introducing how to propagate roses through cutting to improve survival rate and the related experience of rose cutting time and methods for flower planting. Let's find out more from the introduction by the editor.
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 methods for propagating roses, but the most commonly used is cutting. Depending on the position of the cutting, it is divided into new shoot cutting, young 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 are full of vitality, making it easier for them to root and sprout after cutting.
2. Cutting Selection: Choose robust new shoots with full buds, clean them after breaking them off, and 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 soil around it to ensure the plant does not fall over.
4. Post-cutting Care: After cutting, water thoroughly and cover with a layer of plastic film to create a humid environment. Ventilate twice a day, and after 15 days, they can root, 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 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, which improves the survival rate. High temperature and humidity in summer can cause the wound to rot, preventing rooting and sprouting.
2. Cutting Selection: Choose strong, disease-free branches of the current year for young shoot cutting. After the flowering period, remove the flowers and old leaves to accumulate nutrients. When the branches become sturdy, cut them to a length of 10 centimeters, leaving two compound leaves and small leaves, and remove the rest.
3. Cutting Process: Prepare potting soil with decomposed leaves and coarse sand. Dip the lower part of the cut branches in rooting powder and insert them into the potting soil, about two-thirds deep, ensuring that 2-3 buds are exposed.
4. Post-cutting Care: After cutting, water thoroughly and cover the potting soil. If new buds grow and old leaves do not fall, the cutting has been successful.
III. Hard Shoot Cutting
1. Cutting Time: The cutting time for hard shoots 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, leaving 2-3 leaves to prevent them from rotting in the soil, causing bacteria growth, and affecting root development.
3. Cutting Care: Insert the shoot into sand, water thoroughly, set up a frame, cover with a layer of film, and place it in a sunny area to receive light. When the temperature gradually rises, remove the film, and when the leaves turn green, it can be transplanted.
