Platycoryne ochrantha (Schltr.) Summerh.
Platycoryne ochrantha, also known as the Yellow Crested Jewel Orchid, is a small but stunning species of orchid that belongs to the family Orchidaceae. This plant is native to the rainforests of tropical Africa, particularly Mozambique, Tanzania, and Zimbabwe.
Appearance
The Platycoryne ochrantha is a terrestrial orchid that grows to an average height of about 10cm. The plant typically has 3-4 large, ovate leaves that grow up to 10cm in length. Its inflorescence is upright and bears several small yet vibrant yellow flowers that have a distinctive fringed lip. The plant's unique crested labellum is what makes this orchid species so visually striking.
Uses
Platycoryne ochrantha is primarily used for ornamental purposes, valued for its unique appearance and ease of cultivation. It is a popular choice for indoor planting, particularly in terrariums and miniature gardens. This plant is also used in traditional medicine in some parts of Africa, although not much scientific research has been done to confirm its medicinal properties.
Conservation status
Currently, there is no specific data on the conservation status of Platycoryne ochrantha. However, like many other orchid species, this plant is at risk of habitat destruction and human activities. Therefore it's essential to protect the natural habitats in which this plant species thrives to ensure its survival and preservation for generations to come.
Light Requirements
Platycoryne ochrantha typically prefers bright but indirect sunlight. It can survive in partial shade as well, but it may not flower as often or as well. Direct sunlight should be avoided as it can damage the leaves and flowers.
Temperature Preferences
The ideal temperature range for Platycoryne ochrantha is between 20°C to 25°C during the day and 15°C to 18°C during the night. Temperatures below 12°C can harm the plant, leading to stunted growth and even death. In the summer, it's best to keep the plant in a position where it can get some natural air flow, as high temperatures and humidity can lead to fungal infections.
Soil Requirements
Platycoryne ochrantha prefers a well-draining substrate with a slightly acidic to neutral pH. A mixture of orchid bark and perlite works well, with a layer of sphagnum moss added to help retain moisture. The roots of the plant are sensitive to waterlogging, so it's essential to avoid pots without drainage holes or standing water. Fertilizer should be applied regularly in small amounts.
Cultivation Methods of Platycoryne Ochrantha
Platycoryne ochrantha is a terrestrial orchid commonly found in tropical Africa that prefers a humid and warm climate. When it comes to cultivation, it thrives well in a shaded spot with moist and well-drained soil.
The plant prefers a high level of humidity, making it an ideal candidate for terrariums or growing in a greenhouse. It grows well in small pots or containers, making it easier to manage its growth and care.
Watering Needs of Platycoryne Ochrantha
The watering routine for Platycoryne ochrantha needs to follow a strict schedule to avoid overwatering or underwatering the plant. Watering frequency should be done as often as when the top inch of soil is dry to the touch.
It is better to water small amounts of water frequently, ensuring that the soil remains moist but not waterlogged. Overwatering will lead to root rot, which can be disastrous for the plant.
Fertilization of Platycoryne Ochrantha
Platycoryne ochrantha requires regular feeding with a balanced fertilizer. Feed the plant once every two weeks during active growth periods, and feed the plant once a month during the dormant periods.
It is recommended to use a half-strength orchid fertilizer solution for the plant to prevent fertilizer burn, which can damage the roots and burn the leaves.
Pruning of Platycoryne Ochrantha
Platycoryne ochrantha does not require pruning beyond the removal of dead or dying leaves, which can be cut down to the base of the plant using a clean and sharp pair of scissors or shears.
It is essential to disinfect the cutting tool before use to prevent the spread of plant diseases. Regular pruning is not necessary as the plant grows slowly and retains its shape well with minimal intervention.
Propagation of Platycoryne ochrantha
Platycoryne ochrantha is a terrestrial orchid species that is propagated by means of vegetative division and seed germination. Both methods have their own advantages and disadvantages.
Vegetative propagation
Varieties of terrestrial orchids like Platycoryne ochrantha can be easily propagated by division of rhizomes. Although this method is straightforward, it requires utmost care and precision. For this, you need to select a healthy plant, remove it from its pot, and separate small units of rhizomes. Make sure each division has at least one growing tip and a good number of roots. Transplant each section into a new container and then give it plenty of water but avoid overwatering. Too much moisture can cause fungal or bacterial infections that will hinder growth.
Seed Germination
The process of seed germination is more complicated than rhizome division. However, it is the only way to obtain new plants with the same characteristics as the parent. Collect seed pods when the capsules are dry and swollen. Before sowing, soak the seeds in running water to remove the fleshy material and pulp. Use a sterilized substrate or moss, or bark, mix, or sphagnum moss. Scatter the seeds uniformly over the surface and tamp them lightly to ensure good contact with the substrate. Sow the seedlings in individual pots, keep them at a consistent temperature (around 21°C) and humidity, and well-ventilated till they germinate.
Disease Management
Platycoryne ochrantha (Schltr.) Summerh. is prone to several diseases that can affect its growth and yield. Here are some common diseases and their management:
Fungal infections
Fungal infections such as leaf spot, rust, and powdery mildew can affect the leaves and flowers of Platycoryne ochrantha (Schltr.) Summerh. To manage these diseases, it is recommended to remove and dispose of infected plant parts and avoid overhead watering that can wet the leaves. Fungicides can also be applied to control the spread of the disease.
Bacterial infections
Bacterial infections such as soft rot and bacterial leaf spot can affect the stems and leaves of Platycoryne ochrantha (Schltr.) Summerh. To manage these diseases, it is recommended to remove and dispose of infected plant parts and avoid overhead watering that can wet the leaves. Antibacterial agents can also be applied to control the spread of the disease.
Pest Management
Platycoryne ochrantha (Schltr.) Summerh. is also prone to several pests that can affect its growth and yield. Here are some common pests and their management:
Spider mites
Spider mites can cause damage to the leaves of Platycoryne ochrantha (Schltr.) Summerh. To manage these pests, it is recommended to keep the humidity level high and apply insecticidal soaps or oils to the plant.
Thrips
Thrips can feed on the leaves and flowers of Platycoryne ochrantha (Schltr.) Summerh. To manage these pests, it is recommended to use sticky traps to attract and remove the insects. Insecticidal sprays can also be applied to control the population of thrips.
