Light Requirements
Polystachya oxychila Schltr. ex Kraenzl. is an epiphyte that grows well in bright, diffused light. It is important to avoid direct sunlight, which may cause leaf burn. In its natural habitat, P. oxychila grows under the tree canopy, where it receives moderate light.
Temperature Requirements
Polystachya oxychila requires warm and humid conditions for optimal growth. It thrives in temperatures between 20°C to 30°C during the day and 15°C to 20°C at night. A temperature range lower than this may result in the stunting of growth or even death of the plant. In colder climates, the plant can be grown indoors or in a greenhouse with a heating system.
Soil Requirements
Being an epiphyte, Polystachya oxychila does not require soil to grow. Instead, it grows attached to a host tree or on a piece of wood. However, it can still benefit from a substrate that retains moisture and provides the necessary nutrients for growth. Suitable substrates include sphagnum moss, coconut coir, and orchid bark. These substrates should be kept moist, but not waterlogged, to prevent root rot.
Cultivation Methods
Polystachya oxychila Schltr. ex Kraenzl. is an epiphytic orchid that is found in mountainous regions of East and Central Africa. To cultivate this plant, you need to mimic its natural growing conditions and provide it with a suitable environment. Make sure you plant it in a well-draining medium, such as a mix of sphagnum moss, orchid bark, and perlite. You can also mount the plant on a piece of wood to simulate its natural growing conditions. The plant requires bright but filtered light and a warm, humid environment. Keep it away from direct sunlight, drafts, and extreme temperatures.
Watering Needs
Polystachya oxychila Schltr. ex Kraenzl. requires frequent watering, but you need to be careful not to overwater it, as this can lead to root rot. Water the plant two to three times a week, or when the top inch of the medium feels dry to the touch. You can water the plant by immersing the pot in a bucket of water for a few minutes, or by using a spray bottle to mist the plant. Avoid getting water on the leaves or flowers, as this can cause damage.
Fertilization
Polystachya oxychila Schltr. ex Kraenzl. requires regular fertilization to thrive. You can use a general-purpose orchid fertilizer, which you should dilute to half strength, or use a fertilizer specifically formulated for epiphytic orchids. Fertilize the plant once a month during the growing season, which is usually from spring to fall. Do not fertilize the plant during the winter months.
Pruning
Polystachya oxychila Schltr. ex Kraenzl. does not require frequent pruning. You should only remove dead or yellowing leaves from the plant. You can also remove the spent flower stems after the blooms have faded. This will encourage the plant to focus its energy on producing new growth and flowers.
Propagation of Polystachya oxychila Schltr. ex Kraenzl.
The propagation of Polystachya oxychila Schltr. ex Kraenzl. is typically done through vegetative means such as division, keiki production, or cloning techniques. These methods are preferable as the plant does not produce seeds frequently and they have low viability.
Division
Division is the easiest and quickest way to propagate Polystachya oxychila. It is best done during the active growing season when the plant is producing new growth. The plant can be divided into two or more sections, ensuring that each section has enough healthy roots and leaves. The divided sections can be potted up individually and kept in warm, humid conditions to encourage new growth and acclimatization.
Keiki Production
Keikis are small plantlets that develop along the stem of the mother plant. They can be separated from the mother plant when they have developed their own roots, typically when they are a few inches tall. The keiki can then be carefully removed and potted up in its own container. Keiki production is best done in the spring when the plant is actively growing and has developed strong aerial roots.
Cloning
Cloning techniques such as tissue culture or meristem culture can also be used to propagate Polystachya oxychila. Tissue culture involves the cultivation of cells or tissues in a nutrient-rich medium to promote growth. Meristem culture involves taking a small piece of meristem tissue and growing it in a similar medium. Both methods can produce large numbers of identical plants in a relatively short amount of time. However, they require specialized equipment and expertise, making them less accessible to most growers.
Disease and Pest Management for Polystachya Oxychila Schltr. ex Kraenzl.
Polystachya Oxychila Schltr. ex Kraenzl., also known as the Dancing Ladies orchid, is a stunning epiphytic orchid native to Madagascar. While this species is hardy and relatively easy to grow, it is still susceptible to a few diseases and pests that can hinder its growth and appearance.
Common Diseases
One of the most common diseases affecting the Polystachya Oxychila is root rot. This is caused by overwatering, poor drainage, or fungal infection. You can prevent root rot by watering the plant only when the top layer of soil is dry and providing adequate drainage.
Fungal infections can also cause leaf spots, which can be identified as small, water-soaked areas on the leaves. To manage leaf spots, remove the affected leaves and treat the plant with a fungicide solution. Additionally, make sure to improve air circulation around the plant by spacing your plants out or adding a fan to the area where you keep your plants.
Common Pests
There are a few pests that can infest the Polystachya Oxychila. One of the most common pests is the spider mite, which can be identified by fine webbing on the leaves and yellow, discolored foliage. To manage spider mites, rinse the plant with water and apply a miticide solution.
Mealybugs are another common pest that can infest this orchid species. They can be identified as small, white, cotton-like masses on the underside of leaves, and may also leave a sticky residue on the foliage. To manage mealybugs, wipe the plant with a damp cloth and apply an insecticidal soap solution.
Overall, keeping a close eye on your Polystachya Oxychila and ensuring that it is not overwatered, has sufficient air circulation, and is well-spaced from other plants, can help prevent the spread of disease and pest infestations.
