Catharanthus roseus is a plant that originated in tropical regions and was later introduced to our country. Nowadays, many people in our country are growing it, and as more people grow it, the question of how to propagate Catharanthus roseus has become a topic of concern. What are the propagation methods for Catharanthus roseus? Let's take a look together below.

I. How to Propagate Catharanthus roseus / Sowing / Cutting

The question of how to propagate Catharanthus roseus can roughly be divided into two methods: seed sowing propagation and cutting propagation. Both methods have been tested many times and both have high survival rates. As for how to carry out these two propagation methods specifically? There is a detailed explanation below, let's continue reading.

II. Propagation Methods for Catharanthus roseus

Seed Sowing Propagation

1. Sowing Time

Among the propagation methods for Catharanthus roseus, seed sowing is a relatively commonly used method. When carrying out seed sowing propagation, choosing a suitable time is very important. Generally, it is best to sow in spring, because the climate is more suitable and it can greatly improve the survival rate of the seeds.

2. Seed Selection

Regarding how to propagate Catharanthus roseus, seed selection is relatively important. When collecting seeds, when we see the fruit of Catharanthus roseus turning yellow and the black seeds inside becoming visible, we can carry out collection. After collection, the seeds need to be soaked in water for 3-5 days before sowing, which will make the seeds germinate more easily.

3. Sowing Method

When sowing, because the seeds are relatively small, we need to mix the seeds with fine sand and scatter them. After scattering, cover them with about 2-3cm of soil and then water. When watering, be careful to use a spray bottle. If you pour water directly with a watering can, it is very easy to wash the seeds away. Be careful to water thoroughly in one go, and after about 7-10 days the seedlings will emerge.

Cutting Propagation

1. Cutting Time

Regarding how to propagate Catharanthus roseus, choosing the time for propagation is very important. When carrying out cuttings, we can choose the period of late spring and early summer, because Catharanthus roseus prefers light, so this period is the most suitable and can greatly improve the rooting rate of the cuttings.

2. Cutting Selection

The cuttings mentioned here are the branches of Catharanthus roseus. At this time, it is best to choose branches that are relatively robust and free of pests and diseases, so that the survival rate will be relatively high. If you choose branches that already look relatively thin and small, it will be very difficult for them to survive.

3. Cutting Method

Among the propagation methods for Catharanthus roseus, cutting propagation is considered a relatively simple one. First, we can use chopsticks to poke a hole in the soil, then insert the selected cutting into the hole, then press the soil flat and water it. After watering, the cutting will take about 20 days to take root.

How to Sow Catharanthus roseus, Sowing Methods for Catharanthus roseus / Spring Sowing Has a Higher Survival Rate

Among the propagation methods for Catharanthus roseus, there are two types: seed sowing propagation and cutting propagation. Among them, seed sowing propagation is the more commonly used method. So how do you sow Catharanthus roseus? What are the sowing methods for Catharanthus roseus? Let's take a look together below.

II. Sowing Methods for Catharanthus roseus

1. Soil Selection

When sowing Catharanthus roseus, first we need to choose soil. In terms of soil, we can choose relatively loose leaf mold soil. This kind of soil has relatively good drainage and air permeability, and can allow the seeds of Catharanthus roseus to better absorb nutrients.

2. Seed Selection

Regarding how to sow Catharanthus roseus, seed collection is a very important step, because the flowering time of each flower is different, so the seed maturation period is also different, and they cannot be picked casually. When collecting seeds, when we notice that the fruit skin begins to turn yellow and the black seeds inside can be seen through it, we can carry out seed collection.

3. Sowing Time

The most suitable environmental temperature for the growth of Catharanthus roseus seeds is around 20-25°C, so sowing in spring is the most suitable. If sown at this time, the seeds of Catharanthus roseus can germinate more quickly.

4. Sowing Method

Regarding how to sow Catharanthus roseus, the method is actually very simple. First, we need to mix the seeds with fine sand and then evenly scatter them on the soil surface. After that, cover them with about 2cm of soil and then water. Water thoroughly in one go, and after about 7-10 days the seeds will germinate.

5. Follow-up Management

After the seeds of Catharanthus roseus germinate, we can carry out follow-up care. There are also many points to note during care. For specific details, everyone can refer to the article on Catharanthus roseus cultivation methods. I will not introduce too much here.

How to Take Cuttings of Catharanthus roseus, Cutting Methods for Catharanthus roseus / The Selection of Cuttings Is Very Important

Among the propagation methods for Catharanthus roseus, although cutting propagation is used by fewer people compared with seed sowing propagation, its survival rate is not low at all. So how do you take cuttings of Catharanthus roseus? What are the cutting methods for Catharanthus roseus? Let's take a look together below.

II. Cutting Methods for Catharanthus roseus

1. Cutting Time

Catharanthus roseus is a light-loving plant. During its growth, it is best to maintain sufficient light. Therefore, the most suitable time period for taking cuttings is from April to July each year. Taking cuttings at this time will greatly improve the survival rate.

2. Soil Selection

If you want to know how to take cuttings of Catharanthus roseus, soil selection is a relatively key point. Choosing a suitable soil can make the cutting process smoother and make it easier for the cuttings to take root. In terms of soil, we can choose leaf mold soil with relatively high looseness.

3. Cutting Selection

Cuttings refer to the branches of Catharanthus roseus. This part is very important. The quality of the selected branches directly determines the survival rate. In this regard, it is best to choose relatively robust branches, which will greatly improve the survival rate. If you choose branches that already look relatively thin and small, the cutting is basically declared a failure.

4. Cutting Method

Regarding how to take cuttings of Catharanthus roseus, the method is actually very simple. First, we need to find an object about as thick as the cutting and poke a hole in the soil, then insert the cutting into the soil, press it flat, and then water it. Water thoroughly in one go, and after about 20 days it will take root.
