Light Requirements
Polystachya fabriana Geerinck is an epiphytic orchid which means it grows on trees, stumps, or rocks. In its natural habitat, it thrives under the shade of tree canopies. It requires diffused or filtered light that mimics the light intensity and duration under a canopy to thrive. Direct sunlight can cause its leaves to scorch or wither.
Temperature Requirements
The ideal temperature range for Polystachya fabriana Geerinck's growth is between 18°C to 25°C. The orchid is native to tropical rainforests that have a year-round warm climate. Temperatures outside this range can harm the orchid, and exposing it to temperatures below 10°C can damage the plant's roots and leaves.
Soil Requirements
Polystachya fabriana Geerinck grows on the surface of other plants or organic materials. Because it is an epiphytic orchid, it does not require soil to grow. Instead, it needs a medium that can retain moisture and provide support for its roots. A good potting mix for Polystachya fabriana Geerinck should contain organic matter like sphagnum moss, bark, and charcoal. The mix should be well-draining to prevent the roots from rotting.
Cultivation Methods
Polystachya fabriana Geerinck is an orchid species that is natively found in Central Africa. It thrives in humid and warm conditions, making it an ideal indoor plant. To cultivate this plant, you will need to simulate its natural habitat by creating a humid environment.
You can grow Polystachya fabriana Geerinck in pots or mounted on logs or plaques. If you decide to use a pot, make sure to use a well-draining potting medium and ensure that the pot has proper drainage holes. The plant does well in medium to bright indirect light and can be grown in a variety of indoor settings, including homes and offices.
Watering Needs
Polystachya fabriana Geerinck requires frequent watering to maintain its humid environment. You can water the plant every 2 to 3 days or as soon as the potting material begins to dry out. Make sure not to overwater the plant as it can lead to rot and fungal infections.
If you decide to mount the plant on a log or plaque, you can mist it every day to keep it moist. Alternatively, you can immerse the plant and the medium in a bucket of water to ensure complete hydration.
Fertilization
Fertilizing Polystachya fabriana Geerinck is essential for healthy growth and blooming. The plant needs regular feeding every two weeks during the growing season, which is from spring to summer. You can use a balanced fertilizer that has equal parts of nitrogen, phosphorus, and potassium.
The plant also requires occasional feeding during the dormant period, which is in fall and winter. You can reduce the frequency of fertilizer application to once a month in this period.
Pruning
Polystachya fabriana Geerinck does not require much pruning. However, you can prune the plant to remove any dead or diseased foliage. This helps to promote healthy growth and prevent the spread of diseases.
You can also prune the plant after it blooms to remove spent flowers and encourage it to produce new blooms. Make sure to use sterile pruning equipment to prevent the spread of infections.
Propagation of Polystachya fabriana Geerinck
Polystachya fabriana Geerinck is a beautiful orchid native to Africa. It can be propagated through several methods:
Division
Division is the most common way to propagate Polystachya fabriana Geerinck as this orchid produces many pseudobulbs. When the plant has grown too big for the container, the rhizomes can be divided into smaller sections. Each division should have at least two pseudobulbs to ensure survival.
Keiki
Keiki is a Hawaiian term used for "baby" and refers to the miniature plantlets that grow on the sides of mature orchids. Polystachya fabriana Geerinck can produce keiki on its flower spikes. Once the keiki has developed a few roots, it can be separated from the mother plant and planted in its own container.
Seeds
Propagation through seeds is the most challenging way to propagate Polystachya fabriana Geerinck. The plant typically produces a large number of seeds, but they require specific conditions for germination. The seeds need to be sown on a sterile medium and kept moist at all times. They also require a consistent temperature of 70 to 80°F. It can take several weeks for the seeds to germinate, and even longer for the plant to reach a mature size.
Disease and Pest Management for Polystachya fabriana Geerinck
Polystachya fabriana Geerinck is a beautiful orchid species with fascinating blooms. However, like all plants, it is susceptible to diseases and pests. Here are some common diseases and pests that might affect the plant along with suggestions on how to manage them.
Diseases
Black rot, caused by the fungus Pythium ultimum, is a common disease that affects Polystachya fabriana. It causes the leaves to turn black, wither and fall off. To manage this disease, start by removing and destroying any infected plant material. Always use disinfected tools to avoid spreading the fungus. Additionally, reduce watering and increase the temperature and humidity levels to make the environment less favorable for the fungus to grow.
Another disease that can affect Polystachya fabriana is crown rot, which is caused by bacteria or fungi. This disease causes the leaves to yellow and wilt, and the roots to rot. To manage crown rot, start by removing all infected plant material and avoid watering the crown area. Always use clean tools and avoid over-fertilizing the plant as it can weaken it and make it more susceptible to the disease.
Pests
The most common pests that can affect Polystachya fabriana are mealybugs and spider mites. Mealybugs are small, white insects that suck sap from the plant and cause stunted growth. To manage them, physically remove them with a cotton swab dipped in alcohol. You can also use insecticidal soap or neem oil to control the infestation.
Spider mites are tiny, eight-legged insects that thrive in warm and dry conditions. They cause yellowing of the leaves, and the webs they make give the plant a dusty appearance. To manage spider mite infestations, start by spraying the plant with water to remove the webs and increase humidity levels. You can also use insecticidal soap or neem oil to control them.
Pests and diseases can be detrimental to the health and growth of Polystachya fabriana, but with proper management practices, you can keep your plant healthy and thriving.
