Cutting propagation method of Catharanthus roseus

1. Soil preparation

When taking cuttings, the substrate is generally prepared with peat, perlite and vermiculite in a ratio of 4:1:1. After preparation, put it in the flowerpot and water it thoroughly.

2. Cut branches

Generally speaking, pinch 10 to 12 centimeters from the top to the bottom, then use scissors to cut off both sides, cutting off all the leaves at the bottom and leaving 1-2 leaves at the top. Be careful to use scissors, and it is best not to use your hands to avoid infection.

3. Insertion matrix

After cutting, the cuttings are carried out. The cutting time is generally between June and September. The temperature during this period is higher, which is conducive to rooting. When taking cuttings, insert the cuttings to a depth of one-third in summer and two-thirds in spring. In summer, the temperature is high and the seeds are prone to rot. In spring, the temperature is low and the humidity is low, so they should be planted deeper.

4. Post-maintenance

After insertion, spray water immediately and cover with a plastic bag. If conditions are good, you can make a seedbed, cover it with a film, and pay attention to moisturizing. The temperature should be controlled at 20-25 degrees, and it will take about 20 days to take root.
