What are the common propagation methods for roses?

Roses are also known as yueyuehong, siji hua, and so on. They are ornamental plants that bloom in all four seasons, with beautiful colors and graceful forms, blooming all year round, and are deeply loved by the public. Today, the editor will introduce to you the propagation methods of roses.

1. Propagation by sowing

Sowing is a commonly used propagation method for roses. The sowing time is generally in spring each year. Before sowing, the seeds need to be disinfected and germinated to improve seed vigor and increase the emergence rate. First, soak the seeds in warm water for about 10 hours, then treat the seeds with chemicals according to the pests and diseases that need to be controlled. After sowing, do a good job in management to promote seed germination. With proper management, they will germinate and emerge around Qingming Festival. After emergence, they can be transplanted immediately, or in autumn after their leaves fall.

2. Propagation by division

Division is also commonly used for roses, generally carried out in spring and autumn. When dividing, first dig out the entire rose plant with soil from the soil. When digging, be careful not to damage the large roots, so as not to affect the growth of the mother plant. Then select about two robust root strips with fibrous roots, control the planting density, and plant them in the trench. Carry out seedling management and regulate the basic growth conditions such as temperature, moisture, and nutrients. Usually, they can bloom in the same year.

3. Propagation by layering

When layering roses, first pay attention to selecting a thick, pest-free and disease-free branch, then carry out girdling at a position about 10 cm from the mother plant, scrape off the bark at the bottom, keeping the width at about 2 cm, just exposing the branch end. Then apply an appropriate amount of rooting agent to the girdled area, then press it into the soil, or use a breathable material filled with wet soil to wrap the girdled area, tie both ends tightly, and wait for roots to form. Observe its rooting situation regularly. When the branch has rooted and grown new leaves, separate it from the mother plant, and it becomes a new plant.

4. Propagation by cuttings

Cutting propagation has a high rooting rate and is a propagation method with a relatively high usage rate. It is usually carried out in spring and autumn after roses enter the dormant period. First, select a mature branch as a cutting. The cutting must have about 4 buds, then cut each bud into uniform cuttings. If the cuttings are relatively tender, then after cutting, shading work also needs to be done well, and then the soil must be kept moist. Under normal management, about one month after cutting, the cuttings will generally root, and the survival rate can reach about 75%. If the cut end is dipped in rooting agent before cutting, the rooting rate will be even higher.
