Platycoryne tenuicaulis is a terrestrial orchid species found in several African countries, including Uganda, Kenya, Tanzania and Malawi. The species is typically found growing in forested areas and river banks at altitudes ranging from 1100 to 2400 meters above sea level.
Light Requirements
Platycoryne tenuicaulis prefers bright but indirect sunlight in its natural habitat. When grown indoors, the plant should be placed near a window that receives partial sunlight, or under shade cloth if grown outdoors in hotter regions. Direct sunlight may cause the plant's leaves to turn yellow and wither.
Temperature Requirements
This species prefers cooler temperatures ranging from 20°C to 25°C during the day and 15°C to 20°C at night. It thrives in regions with moderate to high humidity levels, which should be maintained by misting the plant regularly. The orchid also cannot tolerate extreme temperature fluctuations.
Soil Requirements
Platycoryne tenuicaulis grows best in rich, well-draining soil with a slightly acidic pH of between 5.5 and 6.5. It requires frequent watering to keep the soil moist but not waterlogged. The medium should be allowed to dry slightly between watering, and any excess water should be drained from the pot to prevent root rot. Fertilizers should be applied monthly during the plant's growth stage with a balanced, water-soluble formula.
Cultivation of Platycoryne tenuicaulis
Platycoryne tenuicaulis is an epiphytic orchid that is best grown in a humid and warm environment. It needs bright, indirect sunlight to thrive and should be protected from direct sunlight, which can damage the leaves and cause dehydration. The orchid can be grown in a pot or mounted on a piece of bark or tree fern to mimic its natural habitat.
Watering Needs
Proper watering of Platycoryne tenuicaulis is essential for its growth and survival. The orchid should be watered frequently, but care must be taken not to overwater it. It's better to allow the soil to dry for a short time between watering periods. Watering should be done in the morning or early afternoon hours to allow the leaves and roots to dry out before nightfall.
Fertilization
Like other Orchidaceae species, Platycoryne tenuicaulis benefits from regular fertilization to promote its growth and flowering. Fertilizers that are high in nitrogen should be avoided as they can cause the orchid to produce foliage at the expense of flowers. A balanced fertilizer with an N-P-K ratio of 20-20-20 is ideal for this orchid. It's recommended to fertilize the plant once a month during the growing season.
Pruning
Pruning of Platycoryne tenuicaulis is essential to maintain its shape and promote its health. Dead or damaged leaves should be removed promptly to avoid the spread of diseases. The orchid can also be pruned to control its size, and this should be done in the early stages of its growth. Pruning should be done with sharp scissors or pruning shears, and care must be taken not to damage the remaining leaves or flowers.
Propagation of Platycoryne tenuicaulis (Rendle) Rolfe
Platycoryne tenuicaulis (Rendle) Rolfe is a terrestrial orchid that can be propagated through various methods, including:
Seed Germination
The most common method of propagating this plant is through seed germination. The seeds should be collected when the seed capsules turn yellow. The seeds should then be sterilized before sowing in a culture medium. The ideal temperature for germinating these seeds is between 20-25°C. The germination process can take anywhere from 6-12 months, and it requires a high level of humidity and good air circulation. After the seedlings have emerged, they should be transferred to separate containers with good drainage and a suitable substrate.
Division
Another propagation method for Platycoryne tenuicaulis is through division, although it is not commonly used. This method is best performed during the plant's dormant season. The entire plant can be carefully removed from the soil and divided into sections, making sure each section has at least one pseudobulb or new growth. The sections should be planted in suitable containers or directly in the garden with good drainage and appropriate soil.
Vegetative Propagation
Vegetative propagation of Platycoryne tenuicaulis is possible, but it is not frequently done. It involves taking a cutting from the plant and treating it with a rooting hormone to encourage root development. The cutting should be planted in a suitable substrate with good drainage and placed under high humidity and low light conditions. Vegetative propagation is not widely used because the success rates are low.
Disease and Pest Management for Platycoryne Tenuicaulis
Platycoryne tenuicaulis is a beautiful orchid plant that requires proper care and attention to prevent it from being affected by various pests and diseases. These issues can significantly damage the plant and reduce its overall health and vitality.

Diseases
Bacterial Soft Rot: Bacterial Soft Rot is a severe disease that causes the plant's leaves and roots to become soft and mushy, eventually leading to plant death. To manage this disease, remove infected parts of the plant immediately to prevent spreading. Disinfect all tools and equipment used to work on the plant with rubbing alcohol or use them only after they've been dried out in sunlight.
Black Spot: Black Spot is a fungal disease that causes black or brown spots to form on the leaves of the plant. To manage this disease, remove any infected leaves immediately. Make sure to keep the plant leaves dry and avoid overwatering. You can also treat the plant with a fungicide spray to prevent further spreading.
Virus Diseases: Platycoryne tenuicaulis is prone to virus diseases that cause yellowing and stunted growth of the plant. There is no treatment for virus diseases. Therefore, the best way to manage this is to remove and destroy infected plants immediately to prevent further spreading.
Pests
Mealybugs: Mealybugs are common pests that attack orchids and cause discoloration and yellowing of the plant. They produce a white, cottony substance on the plant, making them easy to spot. To manage Mealybugs, use a cotton swab dipped in rubbing alcohol to remove these insects. Repeat the process every few days until they are gone. Alternatively, you can use insecticidal soap or neem oil spray to keep them at bay.
Scale Insects: Scale insects look like tiny bumps on the plant's leaves and stems. They feed off the plant's sap, causing yellowing and wilting of the leaves. To manage scale insects, use rubbing alcohol or neem oil spray to remove them from the plant. Repeat the process until they are completely gone.
Spider Mites: Spider Mites are tiny insects that spin webs on the plant. They feed off the plant's sap, causing leaves to turn yellow and eventually fall off. To manage Spider Mites, spray the plant with soapy water, neem oil, or insecticidal soap to kill the mites. Increase the humidity around the plant to deter future infestations.
In summary, the key to preventing diseases and pests in your Platycoryne tenuicaulis plant is to keep it healthy and clean. Monitor your plant regularly and remove any diseased or infected parts immediately. By following these tips, you can ensure your plant stays healthy and beautiful for years to come.
