Catharanthus roseus leaves are bright and shiny, and its branches are covered with dense flowers, which are neat and consistent when blooming, and have good ornamental value. Coupled with heat and drought resistance, less pests and diseases, it is very suitable for potted home landscaping. So when is the best time to grow Catharanthus roseus at home?

First, sowing time

Catharanthus roseus likes warm, slightly dry and sunny environment, and avoids stagnant water, cold and rain and waterlogging.

Second, the sowing conditions

It is recommended to choose open-air sowing when sowing. Catharanthus roseus seeds germinate faster in the case of sufficient sunshine, so we should pay attention to rain and waterlogging prevention in rainy days. If you can't sow in the open air, you should also ensure sufficient light for at least four hours.

In order to prevent Catharanthus roseus from rotting due to moisture, planting soil with good drainage should be selected when selecting soil. Peat soil and perlite can be prepared according to the ratio of 3: 1, or decomposed soil can be used. Choosing shallow pots for potted plants can achieve better drainage effect.
