Cultivation of Didymosalpinx parviflora Keay
Didymosalpinx parviflora Keay, commonly known as the Chinese lantern plant, is an evergreen shrub that requires well-draining soil and a warm climate to grow. The plant thrives in tropical and subtropical regions and prefers partial to full shade. These plants can grow up to 4 meters tall when grown under optimal conditions.
Watering Needs
When it comes to watering Didymosalpinx parviflora Keay, it is best to keep the soil moist but not waterlogged. During hot and dry weather, it is essential to water the plant frequently to avoid drying out of the leaves and flowers. Overwatering can lead to the development of root rot, which is detrimental to the plant's health.
Fertilization
To keep the plant healthy and vigorous, regular fertilization is necessary. Feed the plant every two weeks during the growing season using a balanced fertilizer. However, avoid fertilizing the plant during the winter months when it is dormant, as this may lead to the burning of the roots.
