Comprehensive analysis of how to propagate Catharanthus roseus by cutting and the experience of green plant maintenance regarding the method and timing of Catharanthus roseus cutting, details as follows:
Catharanthus roseus has a long blooming period. As long as the growing environment is suitable, it can bloom almost all year round, making it a plant suitable for ornamental flowers. These pink flowers are often used to decorate urban flower beds. To enjoy more Catharanthus roseus, you need to learn to propagate them. The propagation of Catharanthus roseus is done through cutting. Next, we will introduce the propagation method of Catharanthus roseus through cutting, including soil selection, cutting preparation, cutting method, and planting management.
I. Soil Selection
The soil suitable for the growth of Catharanthus roseus is slightly acidic sandy soil, which can be mixed evenly with humus soil and river sand to make cultivation soil. This cultivation soil is soft and breathable with good drainage.
II. Cutting Preparation
Select one-year-old tender branches from the mother plant of Catharanthus roseus, with a length of 8-10 centimeters being ideal. Cut off the branches and remove the leaves at the bottom of the branches, leaving 2 pairs of leaves at the top. The sap of Catharanthus roseus is toxic. When cutting branches and leaves, the branches will release a large amount of liquid. To prevent direct contact with the sap, gloves should be worn during pruning.
III. Cutting Method
Insert the prepared branches into the cultivation soil, leaving two-thirds of the cutting outside the soil. After inserting, keep the potting soil moist. Maintain the soil temperature at 20-24°C, and wait for about 15-20 days, after which the cuttings will grow roots.
IV. Planting Management
After the cuttings grow roots, they can be planted in a flower pot. Since Catharanthus roseus grows rapidly, it will soon become lush, so a larger pot should be prepared. Place sufficient organic fertilizer at the bottom of the potting soil. After planting, water the soil thoroughly, place it in a shaded and well-ventilated area for a week, and after the plant has adapted, you can move it to a sunny spot.
