How to propagate roses for quick rooting
Main content core guide: This article provides knowledge on how to propagate roses for quick rooting, as well as related information on rose propagation methods and timing, followed by a comprehensive introduction.
Roses have a strong adaptability and are widely distributed in China. They come in many varieties with diverse 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 location of the cutting, it is divided into three types: new bud cutting, softwood cutting, and hardwood 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 are full of vitality, making it easier for them to root and sprout after cutting.
2. Cutting Selection: Choose strong and plump new buds, 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 for rose cutting, 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 press the surrounding soil to ensure the plant does not fall over.
4. Post-Cutting Care: After cutting, water thoroughly and cover with plastic film to create a humid environment. Ventilate morning and evening, and after 15 days, they will root, and the film can be removed after 20 days, preparing for transplantation.

II. Softwood Cutting
1. Cutting Time: Softwood cutting is done in two periods, either from April to May in spring or from September to October in autumn. The climate is relatively warm during these periods, 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. After flowering, remove the flowers and old leaves to accumulate nutrients. When the branches become sturdy, they can be cut. The length of the cut should be 10 centimeters, retaining two compound leaves and small leaves, removing the rest.
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 2-3 buds are exposed.
4. Post-Cutting Care: After cutting, water sufficiently and cover the potting soil. If new buds appear and old leaves do not fall off, the cutting has succeeded.
III. Hardwood Cutting
1. Cutting Time: Choose the intersection of winter and spring for hardwood cutting when the temperature is still relatively cold. Although the cutting will not root immediately, there is a longer preparation time.
2. Cutting Selection: Cut a strong hardwood branch, removing the lower leaves, retaining 2-3, to prevent rot and bacterial growth that could affect root development when inserted into the soil.
3. Cutting Care: Insert the branch into the sand, water thoroughly, set up a frame, cover with a film, and place it in a sunny location. When the temperature gradually rises, remove the film, and when the leaves turn green, it can be transplanted.
