How to Propagate Roses? A Detailed Guide to the Latest Propagation Methods
The rose is a flower native to China, with a rich and colorful range of colors, and it can be seen in botanical gardens all over the country. The rose is also a flower that combines ornamental and medicinal value, and is loved by many people. Now most flower planting bases have roses growing in them. So when we grow roses, how should we propagate them? Below, the editor brings you the propagation methods for roses. Let's take a look!
1. Seed propagation
Sowing is a commonly used propagation method for roses, and the sowing time is generally in spring each year. Before sowing, the seeds should be disinfected and germinated to improve the seeds' germination capacity and increase the seedling emergence rate. First, soak the seeds in warm water for about 10 hours, then carry out seed dressing and disinfection with chemicals according to the pests and diseases that need to be prevented and controlled. After sowing, management work should be done well 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. Division propagation
Division propagation is also used relatively often for roses, generally carried out in spring and autumn. When dividing, first dig out the entire rose plant with soil from the ground. When digging, be careful not to damage the large roots, to prevent affecting the growth of the mother plant. Then choose about two robust root strips with fibrous roots, control the planting density well, and plant them in the trench. Carry out seedling management. Regulate temperature, moisture, nutrients, and other basic growth conditions well, and usually they can bloom in the same year.
3. Layering propagation
When layering roses, first be sure to choose 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, until the branch end is exposed. 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 moist soil and wrap it around the girdled area, tie both ends tightly, and wait for rooting. Observe its rooting situation regularly. When you find that the branch has rooted and grown new leaves, separate it from the mother plant, and it becomes a new plant.
4. Cutting propagation
Cutting propagation has a high rooting rate and is a propagation method with a relatively high usage rate among everyone. It is usually carried out after roses enter dormancy in spring and autumn. First, choose a mature branch as a cutting, and the cutting must be ensured to 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 should be kept moist. Under normal management, generally about one month after cutting, the cuttings will take root, and the survival rate can reach about 75%. If the cut end is dipped in a little rooting agent before cutting, the rooting rate will be even higher.
The above is a brief introduction to rose propagation methods. Roses also have propagation methods such as grafting. These are all commonly used propagation methods for roses. When propagating, we should pay attention to reasonably choosing a good method according to our own techniques and planting direction. That is all for today's introduction.
