Vinca roseus , as a common ornamental plant, is famous for its long-lasting flowering period. As long as the conditions are right, it can bloom almost all year round, attracting many flower lovers to grow it at home. For friends who want to propagate vinca roseus by cuttings, the good news is that the method of propagating vinca roseus by cuttings is very simple. Let’s learn how to make cuttings of Catharanthus roseus take root quickly.

1. Choose healthy branches

When selecting vinca branches for cuttings, you should choose healthy branches that are free of diseases and insect pests. Avoid using branches that are too old or too tender to ensure the success rate of cuttings.

2. Use sterilized tools for pruning

Use sharp, sterilized scissors or blades to prune periwinkle branches, making sure the cuts are smooth to reduce the risk of infection and increase rooting rates.

3. Disinfect flower pots and soil

Thoroughly disinfect the flower pots and soil before cuttings, especially reusable flower pots. It is recommended to use a ceramic pot, a clay pot or a terracotta pot, with a depth of 12 to 18 cm.

4. Hydroponic cuttings

Use rainwater, well water, purified water, or tap water that has been left to stand for a few days for hydroponic cuttings. Hydrogen peroxide can be added to the water to increase the oxygen content and promote rooting.

5. Use sandy soil or humus soil

Make sure to use new, loose, breathable and well-drained potting soil. You can add a small amount of well-rotted compost to the bottom of the pot and avoid using chemical fertilizers .

6. Branch pruning and processing

When pruning, cut below the growth nodes and avoid cutting above the nodes to prevent cut rot. If rooting powder is not available, fungicide can be used instead.

7. Keep an appropriate amount of leaves

When cutting, only 2 to 4 young leaves need to be retained on each branch to reduce water consumption and promote rooting.

8. Hydroponic cutting rooting

Soak the bottom 3 cm of the branches in a transparent container, change the water regularly to keep the water fresh and promote root growth. After the hydroponic roots have taken shape, provide appropriate soft light, maintain the ambient temperature at about 22 degrees, and the humidity above 50%.

9. Cuttings with river sand and potting soil

River sand cuttings provide good drainage and air permeability. After cleaning the river sand, use pots of appropriate depth for cuttings. Water regularly to keep moist.

In short, through these detailed steps, you can effectively improve the success rate of vinca cuttings. Whether it is hydroponics or soil cultivation, you can easily breed beautiful vinca at home.
