Soil Requirements
Polystachya praecipitis Summerh. is an epiphytic orchid and doesn't require soil to grow. Instead, it grows on the surface of other plants or on tree trunks in nature. When grown in pots, it should be planted in a loose, well-draining medium, such as sphagnum moss or bark chips. It should be watered when the potting medium feels almost dry to the touch. Providing good air circulation and avoiding waterlogged conditions will prevent root rot and promote healthy growth.
Cultivation Methods
Polystachya praecipitis Summerh. is an orchid species that is native to the tropical regions of Africa. It is an epiphytic orchid that grows on tree branches and trunks, which makes its cultivation relatively simple. To cultivate Polystachya praecipitis, it is recommended to grow it in a well-draining orchid bark mix or a mixture of sphagnum moss and perlite. The orchid should be planted in a small container with ample drainage holes to ensure that the roots do not stay wet, which can cause root rot. The container should be placed in a location that receives indirect or filtered light and away from direct sunlight.
Watering Needs
The watering needs of Polystachya praecipitis are relatively easy to manage. The orchid should be watered when the top layer of the growing medium feels dry to the touch, which is usually every seven to ten days. It is important not to overwater the orchid, as too much moisture can cause root rot. When watering, it is preferable to use room temperature water and avoid getting water directly on the leaves or pseudobulbs, as it can cause rot or fungal disease.
Fertilization
To ensure optimal growth and flowering of Polystachya praecipitis, the orchid should be fertilized regularly. It is recommended to use a balanced orchid fertilizer, which contains equal parts of nitrogen, phosphorus, and potassium, and an additional dose of trace elements. The orchid should be fertilized once a week during the growing season, which is usually from spring to early fall. During the dormant season, the orchid should be fertilized every four to six weeks.
Pruning
Polystachya praecipitis does not require frequent pruning, as it typically produces new growths from the base of the plant. However, dead or yellowing leaves and pseudobulbs can be removed with a clean, sharp tool to encourage new growth and to prevent the spread of disease. It is recommended to disinfect the tool with rubbing alcohol or a bleach solution before and after use.
Propagation methods for Polystachya praecipitis Summerh.
Polystachya praecipitis Summerh. can be propagated using various methods depending on the environmental conditions, available resources, and grower preferences. The following are some of the most common propagation methods.
Division
Division involves separating the plant into smaller sections, each with its own roots and stem. This method is best suited for mature plants and is usually done during the growing season when the plant is actively growing. The sections can be potted separately in a well-draining medium, watered regularly, and placed in a bright spot with indirect sunlight. They should be kept moist until new growth appears, after which the watering can be reduced to avoid root rot.
Backbulb propagation
Backbulb propagation involves using the old, dormant bulbs of the plant to grow new ones. This method is ideal when there are no healthy pseudo bulbs available or when a larger quantity of new plants is required. The backbulbs should be gently removed from the mother plant, cleaned, and inspected for any signs of damage or disease. They can then be potted in a growing medium composed of orchid bark, perlite, and sphagnum moss. The bulbs should be kept moist and placed in a warm, humid location with indirect light. New growth should be visible in a few weeks, and watering can be adjusted accordingly.
Sowing seeds
Seeds are another popular method of propagating Polystachya praecipitis Summerh. However, this method requires more patience and may take longer to produce mature plants. The seeds should be collected from a mature plant, cleaned, and disinfected to prevent any fungal or bacterial diseases. They can be sown in sterile, well-draining media, covered lightly, and kept moist and warm. The container should be covered with plastic wrap or a lid that allows for some airflow. The seedlings should be transplanted into individual pots once they have developed a few leaves, and care should be taken not to damage their delicate roots.
