Catharanthus roseus is a versatile and easy-to-grow plant that can be propagated in several ways.

The two primary methods of propagation are sexual and asexual. Sexual propagation involves the use of seeds, which can be purchased online or collected from mature plants.

When collecting seeds from plants, it is essential to harvest only those from plants with desirable traits, as the seeds are likely to pass on those traits to the offspring. To sow seeds, plant them in soil that has been loosened and moistened.

Cover them lightly with soil and keep them in an area where the temperature is between 70-75F. Keep the soil moist until the seeds have germinated, which should take between one to three weeks.

Catharanthus roseus can also be propagated asexually through stem cuttings, which is a faster and more reliable method. To propagate the plant through stem cuttings, first, choose a healthy, mature plant from which to take cuttings.

Cut off a stem with a sharp, sterilized blade just below the leaves and remove the lower leaves to prevent them from rotting. Dip the stem cutting in rooting hormone, which will help it take root more quickly, and plant it in soil that has been loosened and moistened.

Keep the soil moist and the cutting in a warm, well-lit area, but not in direct sunlight. Within two to four weeks, the cutting should start to produce roots, and after eight to ten weeks, it should be fully rooted.
