Renanthera coccinea, also known as orange topaz phoenix and orange-yellow cattela, is a plant of the genus Orchidaceae. Flame orchid is native to tropical and ** regions of Asia, including India, Malaysia, Indonesia and other countries. The flowers of the flame orchid are bright and beautiful, and they have a high ornamental value. The following are the cultivation methods and precautions of flame orchid:
Light: Flame orchids prefer plenty of light and are best provided with at least 6-8 hours of direct sunlight per day. When growing indoors, it is best to place the flame orchid near a south- or east-facing window to ensure adequate light.
Moisture: Flame orchid prefers a moist environment, but is not tolerant to moisture. During the growing season, the soil should be kept slightly moist, but not waterlogged. In winter, the growth rate of flame orchids will slow down due to the lower temperatures, and the amount of watering should be reduced appropriately at this time to avoid root rot.
Temperature: Flame orchid prefers a warm and humid environment, and the suitable growth temperature is 18-30. In winter, the flame orchid should be moved indoors to keep warm to avoid poor plant growth due to low temperatures.
Soil: Flame orchid prefers loose, well-drained soil. Cultured soil made from a mixture of humus, river sand, perlite, etc. can be used. When planting, an appropriate amount of bone meal or decaying organic fertilizer can be added to the soil to increase the fertility of the soil.
Fertilization: Flame orchids need adequate nutrients during the growing season. During the growing season, you can apply a well-rotted organic fertilizer or compound fertilizer every 2-3 weeks. During the flowering period, phosphorus and potassium fertilizers should be added to promote the opening of flowers. During the winter months, the amount of fertilizer should be reduced due to the slowing growth rate of the flame orchid.
Propagation: Flame orchids can be propagated by dividing the plant. In spring or autumn, the plants of the flame orchid are removed from the pot, the separated seedlings are planted in a new pot, and then watered thoroughly. After planting, attention should be paid to keeping the soil slightly moist and placed in a cool and ventilated place, and gradually increase the light after the seedlings resume growth.
Precautions: Flame orchid is not cold-tolerant, and should be kept warm in winter to avoid poor plant growth caused by too low temperature.
When watering, one should avoid pouring water directly on the flowers, which can cause the flowers to rot.
Flame orchids prefer a clean environment and should be cleaned regularly to maintain the photosynthesis of the leaves.
When planting flame orchids, you should choose the right potting utensils to avoid too large or too small pots that affect the growth of flame orchids.
