Origin
Platycoryne wilfordii (Ridl.) Rolfe, also known as Wilford's Platycoryne, is a species of orchid that is originally from Southeast Asia, specifically from countries such as Thailand, Singapore, Borneo, and Malaysia.
Common Names
Aside from Wilford's Platycoryne, this plant also goes by other common names such as spoon-lip orchid, elephant-ear orchid, and broad-lip orchid.
Uses
Although this orchid does not have any significant medicinal or commercial value, it is highly sought after by orchid hobbyists and collectors for its unique and attractive appearance.
General Appearance
The Platycoryne wilfordii is a terrestrial orchid that can grow up to 60 centimeters tall. It has large and elongated leaves that resemble elephant ears, hence its common name. Its inflorescence is upright and can bear up to 15 flowers that range in color from pinkish-purple to maroon. The most distinct feature of this orchid is its spoon-shaped lip which is broad and flat, giving the flower a unique appearance. The Platycoryne wilfordii blooms during the months of June to September and prefers shady and moist habitats.
Light Requirements
Platycoryne wilfordii requires moderate to bright indirect light. Direct sunlight can harm the plant and lead to leaf burn. The ideal location for this plant is near a window that receives filtered light for most of the day. Artificial light can also be used to grow this plant successfully.
Temperature Requirements
This plant prefers warm temperatures between 18°C to 25°C (64°F to 77°F). It is essential to keep the plant away from cold drafts or temperature fluctuations. If the temperature drops below 15°C (59°F), it can cause the plant to wilt.
Soil Requirements
Platycoryne wilfordii requires well-draining, aerated soil to grow and thrive. A mix of peat moss, perlite, and orchid bark is a good choice for this plant. The pH of the soil should be slightly acidic, with a range between 5.5 and 6.5.
Cultivation Methods
Platycoryne wilfordii (Ridl.) Rolfe is commonly known as the "Golden Water Spider Orchid." This plant is rare and can be challenging to cultivate. It needs a moist and shaded environment, making it an ideal plant for a greenhouse or terrarium.
The recommended temperature for the plant is between 20-25°C, and it is advisable to use a well-draining substrate such as orchid bark mix or sphagnum moss. Plant the orchid in a small pot with good drainage, and use a support stake to keep it upright.
Watering Needs
The Golden Water Spider Orchid needs to be kept moist, but be careful not to overwater as this can lead to root rot. Water the orchid when the top of the substrate feels dry but never let it dry out completely. Mist the foliage regularly, and avoid getting water on the flowers as this can cause them to deteriorate quickly.
Fertilization
It is essential to fertilize the Golden Water Spider Orchid during its growing season, typically in spring and summer. Use a balanced orchid fertilizer, diluted to half strength, and apply it every two weeks. Always water the plant before fertilizing.
Pruning
Golden Water Spider Orchids do not require pruning. However, it is essential to remove yellowing or dying leaves to prevent rot and disease. Sterilize pruning shears before use and remove the leaf at the base of the stem.
Propagation of Platycoryne wilfordii (Ridl.) Rolfe
Platycoryne wilfordii (Ridl.) Rolfe is an orchid species that can be propagated using two main methods: seeds and division.
Propagation by seeds
Seeds of Platycoryne wilfordii (Ridl.) Rolfe can be obtained from mature seed pods that are left to dry on the plant. The seeds are small and dust-like, and they should be sown immediately after collecting them, as they lose viability quickly. Sowing can be done in flasks or on small pots that contain a well-draining medium. It is advisable to sterilize the containers and the medium to avoid contamination. The seeds should be kept moist and in a warm, shaded area, under low light intensity or artificial light. Within a few weeks, small protocorms should emerge from the seeds, and they can be transferred to individual containers once they have grown enough.
Propagation by division
Platycoryne wilfordii (Ridl.) Rolfe can also be propagated by division, which involves separating the plant into smaller sections that can develop into individual plants. This method is usually done during repotting, and it is best to carry it out when the plant shows signs of new growth. The plant should be carefully removed from its container, and the roots should be inspected for healthy sections. The plant can then be divided into smaller clumps, each with a few healthy growth points and roots. The resulting sections can be planted in separate containers, with a well-draining medium, and kept moist until new growth shows.
Disease and Pest Management for Platycoryne wilfordii (Ridl.) Rolfe
Platycoryne wilfordii (Ridl.) Rolfe is a beautiful orchid species that is native to Borneo. Like all plants, it is vulnerable to diseases and pests that can affect its growth and overall quality. Here are some of the common diseases and pests that might affect this plant and ways to manage them:
Diseases
Bacterial soft rot: This disease can cause the plant to rot and eventually die. It is caused by bacteria that thrive in moist and warm conditions. To manage this disease, it is advisable to avoid overwatering the plants and ensure proper drainage. Infected parts of the plant should be removed and destroyed, and the remaining parts should be treated with a fungicide to prevent further spread of the disease.
Fungal leaf spots: This disease is characterized by the appearance of circular or irregular spots on the plant's leaves. It is caused by fungi that thrive in warm and humid conditions. Management strategies for this disease include keeping the plant's leaves dry, avoiding overcrowding, and proper spacing of plants to promote air circulation. Infected plants can be treated with a fungicide to prevent further spread of the disease.
Pests
Spider mites: Spider mites are tiny pests that like to feed on the plant's leaves, often causing discoloration and damage. To manage spider mites, regular inspection of the plants should be carried out, and any infested plants isolated. Infected plants should be treated with an insecticide as soon as possible to prevent further spread of the pests.
Scale insects: These insects are tiny and flat, and they attach themselves on the stems of plants and suck sap from the plant, leading to stunted growth. Management strategies include isolation of infected plants and treatment with insecticides. Care must be taken not to damage the plant's stem during treatment.
Overall, the best strategy for managing diseases and pests in Platycoryne wilfordii (Ridl.) Rolfe is to keep the plant healthy by providing optimal care conditions and conducting regular inspections.
