Harvesting can be done either once per year or year round, depending on the species and the climate. The flowering and fruiting of the plants are dependent on the cycle of rainy seasons. The blooming of flowers often occurs during the rainy season, while the fruit matures within 9 to 11 months afterwards. The perfectly ripened berries are bright red, glossy, and firm.
