How to propagate the刺梅 (thorn rose) through cutting and rooting
An introduction to the green plant flowers that explains in detail how to propagate the thorn rose through cutting, rooting, and the methods and precautions for its breeding. The following is an introduction for you.
The thorn rose, also known as Euphorbia milii, is a very beautiful flower with a rich variety of colors and lush green leaves, which many people find delightful. Some enthusiasts may know that it requires proper cutting for propagation. So how should it be propagated? What are the precautions for breeding thorn roses? Let me tell you below.
I. How to propagate thorn roses through cutting?
1. Cutting Time
The cutting time greatly affects the survival rate of the thorn rose. If we want to ensure the survival of the cuttings, it is best to choose the period from late April to early June every year because the temperature during this time is especially suitable for the growth of thorn roses, thereby significantly improving the survival rate.
2. Choosing Branches
The choice of branches also affects the survival rate of thorn roses. Generally, we should choose branches that are strong-growing and undamaged, which are one-year-old. These branches have a high germination rate and are easy to survive. Older branches have poor growth potential and are not easy to root, while very young branches lack adaptability and are not easy to survive.
3. Pruning Branches
After selecting the branches, we also need to prune them because thorn roses do not have roots during cutting and cannot absorb nutrients from the soil. If there are too many leaves on the branches, they will consume a lot of nutrients and affect the survival rate. Generally, we keep the branches about 10 centimeters long and retain the leaves of three nodes.
4. Start Cutting
First, use a stick to make a hole in the soil, which can reduce damage to the thorn rose branches. The depth of the hole should be about five centimeters, then insert the thorn rose cutting into the hole, and gently pat the soil firm. Usually, after about one month of care, the thorn rose can root.
II. Precautions for breeding thorn roses
1. Since thorn roses belong to the upright vines, the branches may fall over as they grow taller. You can use bamboo sticks or other objects to tie them for support, or use bamboo sticks to build a frame and shape it into various landscapes, such as spherical or animal shapes, which makes it more interesting to observe.
2. The rumor of thorn roses causing cancer is not scientific. There is no scientific basis for this claim so far. It is said that Euphorbia milii can release carcinogens, but if it could really cause cancer, it would have been banned long ago.
3. The toxicity of thorn roses: Euphorbia milii is indeed toxic, but only if the white latex secreted from the plant's wounds is ingested. If it is not eaten, there will be no poisoning.
4. Since Euphorbia milii prefers a warm environment, the temperature in winter should not be lower than 12℃.
