How to propagate Cleome hassleriana? Introduction to seed sowing and cutting methods

Cleome hassleriana is a highly ornamental plant, and many people grow it. However, as more people grow it, people are also more curious about its propagation. So how do you propagate Cleome hassleriana? What are the propagation methods for Cleome hassleriana? Below, the editor takes everyone to learn about it.

I. How to propagate Cleome hassleriana, sowing/cutting

As for how to propagate Cleome hassleriana, it is mainly divided into two methods: propagation by sowing and propagation by cutting. As long as we operate properly, the survival rates of both propagation methods are relatively high. Below are the specific operation methods for propagation by sowing and propagation by cutting. Friends who are interested can learn about them.

II. Propagation methods for Cleome hassleriana (propagation by sowing)

1. Substrate selection, sandy loam soil

Cleome hassleriana relatively prefers loose, fertile, slightly acidic sandy loam soil, so we can choose this kind of soil as the substrate. This soil has relatively good drainage and air permeability, can let Cleome hassleriana grow better, and is also less prone to water accumulation.

2. Seed germination promotion, soaking in warm water

Before propagating Cleome hassleriana by sowing, we also need to promote germination of the seeds. We can soak the seeds in warm water at about 25-30°C for about 3-10 hours. When the seeds begin to absorb water and swell, we can take them out and sow them. This can make the seeds germinate faster.

3. Sowing method, cover with 1-2cm of soil

Among the propagation methods for Cleome hassleriana, propagation by sowing is a relatively commonly used one. Because its seeds are small, we can use a toothpick dipped in water to stick the seeds one by one and place them on the substrate, then cover them with 1-2cm of substrate and water them. When watering, we can put the flowerpot into water and let the water slowly soak up from below.

III. Propagation methods for Cleome hassleriana (propagation by cutting)

1. Cutting selection, choose robust branches

As for the substrate, propagation by cutting is the same as propagation by sowing. Everyone can prepare the substrate according to the above text. The editor will not repeat it here. However, before cutting, we need to first select the cuttings. This step is very important. The quality of the cuttings has a great impact on the survival rate. We had best choose Cleome hassleriana branches that grow robustly and are free of pests and diseases as cuttings. If we choose branches that already look rather weak, then it is basically very difficult for them to survive.

2. Cutting method, water thoroughly after inserting

Among the propagation methods for Cleome hassleriana, propagation by cutting is relatively simple. Before cutting, we can first use chopsticks to poke a hole in the soil, then insert the cutting into it and press the soil flat, then water it. When watering, be careful to water thoroughly at one time, then place it in a shady place for about a week before moving it outdoors.

3. Follow-up management, control temperature at 18°C-25°C

After cutting is completed, we need to control the ambient temperature. The optimum temperature for the cuttings to take root is 18°C-25°C. If the temperature is lower than 18°C, it is very difficult to take root, while if it is higher than 25°C, it is very easy for some pathogens to breed, thereby causing problems such as pests and diseases. So we had best control the ambient temperature between 18°C-25°C.

How to propagate Cleome hassleriana, sowing and cutting methods

How to propagate Cleome hassleriana? Generally, it can be propagated by sowing and cutting. Both propagation methods are acceptable. Flower friends can choose a suitable propagation method according to their own conditions. Below, the cutting and sowing propagation methods for Cleome hassleriana are separately organized for flower friends to consult.

The sowing time for Cleome hassleriana is generally in mid-April.

First sow Cleome hassleriana seeds in an open-field seedbed, and the seedlings emerge neatly. Generally, the seedlings of Cleome hassleriana grow slowly. After sowing, thinning should be done in time. Transplant when there are 2-3 true leaves, and set out or pot in June.

During the growth period, Cleome hassleriana is fertilized once every half month. If too much fertilizer is applied, the plants are prone to excessive vegetative growth, affecting plant form and flowering. Generally, those sown in spring bloom in autumn, and those sown in autumn bloom indoors in winter and spring.

First prepare the materials for Cleome hassleriana cuttings, such as nutrient soil or river sand, peat soil, and Cleome hassleriana branches, then insert Cleome hassleriana into the prepared potting soil.

Generally, the optimum temperature for Cleome hassleriana cuttings to take root is 18-25°C. Below 18°C, the relative air humidity must be kept at 75-85%. Humidity can be increased by spraying the cuttings. At the same time, 50-80% of sunlight must be blocked. After the root system grows out, gradually remove the shading net.

How to cut Cleome hassleriana, Cleome hassleriana cutting method

Besides propagation by sowing, Cleome hassleriana can also be propagated by cutting. The cutting operation for Cleome hassleriana is not difficult either. Below, the methods and steps for cutting Cleome hassleriana are organized.

For the soil used for cutting Cleome hassleriana, generally nutrient soil or a mixture of river sand and peat soil can be used. In addition, the cutting soil must be disinfected.

For selecting Cleome hassleriana branches, generally flower friends can, when pinching Cleome hassleriana, use the robust, pest-free and disease-free top shoots that are pinched off as cuttings, and directly use the top shoots for cutting.

Once the branches are all selected, the branches can be directly inserted into the prepared soil. After the branches are inserted, they need to be pressed firm, and then the soil only needs to be kept moist.

Humidity control: After cutting, the relative air humidity must be kept at 75-85%. The cuttings can be sprayed to increase humidity, 1-3 times a day is enough. If it is cloudy and rainy, the lower the temperature, the fewer times to spray or do not spray, to avoid the cuttings being easily infected by pathogens and rotting.

Light control: After cutting, light is indispensable, but strong light should be avoided, so after cutting, 50-80% of sunlight must be blocked. After the root system grows out, gradually remove the shading net: on sunny days, remove the shading net at 4:00 pm every day, and cover the shading net before 9:00 am the next day.

Temperature control: The suitable temperature for Cleome hassleriana cuttings to take root is 18°C-25°C. If the temperature is lower than 18°C, the cuttings will have difficulty taking root and will be slow. If the temperature is higher than 25°C, the cut ends of the cuttings are easily infected by pathogens and rot, and the higher the temperature, the greater the proportion of cuttings that rot.
