How to grow and maintain Goldfish Plant (Columnea gloriosa):
It thrives best in bright light but keeps out of direct sunlight, which will turn leaves brown. An eastern facing window is perfect. They can also successfully be grown under lights indoors, especially during the winter.
It grows best in well-drained, any good potting mix. Use a peat moss-based mix, such as African violet potting mix.
Water thoroughly, spring through fall and allow the top inch of soil to dry out between waterings. In the winter, water less often and allowing the soil to become almost dry between waterings. However, the soil should never dry out completely.
It prefers average room temperatures 65°F – 75°F / 18°C – 24°C year-round. Exposure to cold will cause its leaves to fall off.
It prefers moderate to high humidity. Use a room humidifier or a humidity tray to maintain moist air. Mist foliage every day, use room-temperature water because cold water will cause brown spots on the foliage.
Fertilizer every 2 weeks spring and summer with a high-phosphorus liquid fertilizer (such as 10-30-10) diluted by half.
It can be easily propagated by stem-tip cuttings. Take 10 cm (4-inch) stem tip cuttings (without flower buds on them) in spring or summer.
Pests and Diseases:
