Reproduction methods of Catharanthus roseus
The editor will explain the reproduction methods of Catharanthus roseus in the field of green plants and flowers. Let's understand together.
Reproduction methods of Catharanthus roseus
There are several reproduction methods for Catharanthus roseus, not only soil insertion but also water insertion for root growth, as well as cutting, sowing, and tissue culture methods. Among them, sowing is the most commonly used method with a high survival rate, usually carried out in April of spring, with the temperature controlled at around 20 degrees after sowing. Seedlings emerge in about half a month and require sufficient light after emergence for maintenance.

Sowing Reproduction
(1) Timing: When sowing Catharanthus roseus, it is usually done in April of spring when the temperature is stable at around 20 degrees, which is suitable for germination and root growth.
(2) Method: Place disinfected leaf mold, fine sand, and cultivation soil in the flower pot, sprinkle the seeds evenly, control the temperature at around 20 degrees, and seedlings emerge in about half a month. After the seedlings grow, provide sufficient light and water every 3-5 days, with appropriate application of phosphorus and potassium fertilizer.
Cutting Reproduction
(1) Timing: Catharanthus roseus prefers a warm and well-lit growing environment, so the cutting time is around April to July, making sure that the temperature around the cuttings does not exceed 30 degrees.
(2) Method: Cut 10 cm long tender branches from the perennial old plants, remove the lower leaves, leaving only 3-4 leaves at the top, and insert the branches directly into the sand bed. Maintain the soil moisture and control the temperature between 20-24 degrees. The cuttings root after 15-20 days, and when the seedlings grow to about 10 cm, pinch the top.
Tissue Culture
Tissue culture is a highly challenging cultivation method, using professional culture dishes and nutrient solutions, and selecting shoot tips for culture. After 30 days, adventitious buds will grow, and then replacing the nutrient solution, after another 15 days, small white roots will grow and gradually develop into plants. Tissue culture is quite difficult, so it is better to understand it and it is not recommended to try it.
