Catharanthus roseus cutting time

Catharanthus roseus is usually propagated by cuttings in spring and autumn every year, generally around April to July. The surrounding temperature should not exceed 30 degrees. The temperature during this period is relatively high, which is conducive to rooting. If the temperature is high in summer, it is easy to rot, so the cuttings should be shallow. The temperature and humidity are low in spring, so they should be inserted deeper.

Catharanthus roseus cutting method

Before cutting Catharanthus roseus, prepare the soil with peat, perlite and vermiculite in proportion and water it thoroughly. Then cut branches of about 10 cm to 12 cm and trim the branches to leave only 1-2 leaves on the top. When cutting, pay attention to the appropriate depth, spray water in time and cover with a plastic bag. Place it in an environment between 20-25 degrees. It will take root in about 20 days.

Rooting of Catharanthus roseus cuttings

The fastest way to make Catharanthus roseus cuttings take root is to first select acidic sandy soil before cuttings, select one-year-old shoots from the mother plant of Catharanthus roseus, and cut the prepared branches into the culture soil. Two-thirds of the cuttings should be left outside the culture soil. After cuttings, keep the potting soil moist and the soil temperature between 20-24℃. Wait for about 15-20 days, and the cuttings will grow roots.
