How many years can vinca roseus be grown

1. Annual cultivation

Generally speaking, Catharanthus roseus is cultivated as an annual. If the breeding technology is not good, the flowers will be very small and weak starting from the second year, which will seriously affect the appearance.

2. Perennial Flowers

Catharanthus roseus is actually a perennial flower, which means that during the cultivation period, if the maintenance method is proper, a favorable living environment is provided for it, and sufficient fertilizer is applied in time to supplement sufficient nutrients, it can bloom and reproduce every year. However, if the maintenance method is improper, if you don't know how to grow it, and if you can't give it careful care, the flowers that bloom in the second year and after will be very small, which greatly reduces its ornamental value.
