Is it better to use a large or small pot for Periwinkle?

The size of the pot you choose for Catharanthus roseus depends on the size of the plant. If it is a seedling, you can use a pot with a diameter of about 15 cm. If it is an adult plant, you need to use a larger pot. A small pot is not conducive to the growth of the plant.

Growth environment: Catharanthus roseus likes high temperature and high humidity. The suitable temperature for growth is 20-33℃. It needs to be watered every 3-5 days during the growing period, and fertilizer should be applied frequently and in thin amounts.

Repotting time: Catharanthus roseus needs to be repotted every 2-3 years. March to May in spring is the best time to repot, as the survival rate is the highest at this time.

Do you use a deep or shallow pot for Periwinkle?

Catharanthus roseus is a shallow-rooted plant, so you can use a shallow pot when growing it. The depth of the pot needs to be about 3 cm deeper than the root system, which is most suitable for the growth of the plant.

Catharanthus roseus is best grown in a purple clay pot, which is not only breathable but also beautiful. However, this type of pot is relatively expensive, so it is not very cost-effective to use it to grow Catharanthus roseus.
