What are the time and method for rose cutting propagation?
Today's sharing: What are the time and method for rose cutting propagation and related content about the best cutting techniques for roses, and the following editor will introduce them.
Roses have a 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 is the cutting method, which is divided into new bud cutting, tender shoot cutting, and hard shoot cutting depending on the location of the 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 are just sprouted and have strong vitality, making it easier to take root and sprout after cutting.
2. Cutting Selection: Choose robust and full new buds, remove them and wash them clean, 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 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 compact 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. Open for ventilation morning and evening, and after 15 days, the roots can take hold, 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 spring (April-May) and the other in autumn (September-October). The climate during these periods is relatively warm, and the survival rate is higher. High temperatures and humidity in summer can easily lead to wound rot, preventing root growth.
2. Cutting Selection: Choose healthy annual branches free from diseases and pests for tender shoot cutting. After the flowering period, remove the flowers and old leaves to accumulate nutrients. When the branches are robust, they can be cut. The length to cut is 10 cm, keeping two compound leaves and small leaves, and removing the rest.
3. Cutting Process: Mix potting soil with decayed leaves and coarse sand. Dip the lower part of the cut branches in rooting powder, insert them 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, 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 immediately root, they have a longer preparation time.
2. Cutting Selection: Cut a robust hard shoot, removing the lower leaves, keeping 2-3, to prevent leaf rot in the soil, which can cause bacterial growth and affect root development.
3. Cutting Care: Insert the shoot into sand, water thoroughly, then set up a frame, cover with a 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.
That is a detailed introduction to the time and method for rose cutting propagation and the best cutting techniques for roses. Do you understand now?
