Overview
Pachidendron supralaeve, commonly known as the Stalkless Slipper Orchid or Haworth's Pachy, is a beautiful perennial orchid species belonging to the family Orchidaceae.
Origin and Distribution
The plant is native to the Himalayas in Bhutan and India at elevations of 1000 to 2300 meters. It prefers the cool, humid environment of sub-tropical to tropical climates.
Appearance
Pachidendron supralaeve has a compact growth habit and typically forms densely clumped growths. The plant grows to a height of about 30 cm and the leaves are oval-shaped, 6-10 cm long and 3-5 cm wide with a light green color. It produces large and colorful flowers that bloom from spring until summer, with a soft fragrance and long-lasting beauty. The flowers are usually white or green, with a light pink lip.
This plant does not produce pseudobulbs and its rhizomes are thick. It has a strong root system which anchors it firmly. Its leaves have a tough and leathery texture.
Uses
Pachidendron supralaeve is used for ornamental purposes because of its beautiful and long-lasting flowers. It thrives well in pots or baskets and can also be grown outdoors in shaded gardens. It can be propagated through division of clumps or by sowing seeds.
The plant is known to have medicinal properties. Its leaves, roots, and rhizomes are used to treat wounds, fever, diarrhea, and ulcers. The extracts are also used as a natural remedy for various ailments.
Additionally, some cultures believe that the plant has mystical powers and use it for religious and cultural ceremonies.
However, it is important to note that the plant can be toxic when ingested and should be kept away from children and pets.
Light Requirements
Pachidendron supralaeve requires moderate to bright indirect light. Direct sunlight can scorch the leaves, and insufficient light will cause the plant to become leggy. A north or east-facing window is ideal for this plant.
Temperature Requirements
This plant prefers warm temperatures, ideally between 18-24°C (65-75°F). It does not tolerate cold temperatures well and should be kept away from drafts.
Soil Requirements
Pachidendron supralaeve grows best in well-draining soil that is rich in organic matter. The soil should be kept evenly moist but not waterlogged to avoid root rot. A mixture of peat moss, perlite, and vermiculite is suitable for this plant.
Fertilizer Requirements
This plant benefits from regular fertilization during the growing season, which is from spring to fall. Using a balanced, water-soluble fertilizer once a month will provide the necessary nutrients for healthy growth.
Humidity Requirements
Pachidendron supralaeve needs moderate to high humidity levels. To increase humidity, the plant can be grouped with other plants, placed on a tray of pebbles filled with water, or misted regularly.
Cultivation Methods
Pachidendron supralaeve (Haw.) Haw., also known as the "Thick-lipped Pachidendron," is native to Brazil and can be grown in subtropical and tropical environments. For optimal growth, this plant needs a well-draining medium, preferably a mix of peat moss, perlite, and coarse sand. The plant prefers to be grown in partial shade, but it can tolerate a few hours of direct sunlight.Watering Needs
When it comes to watering Pachidendron supralaeve, it's important to water the plant deeply, but not frequently. Overwatering can lead to root rot and other fungal diseases. The frequency of watering will depend on environmental conditions, such as temperature and humidity. It's best to allow the top inch of soil to dry out before watering again.Fertilization
Fertilizing Pachidendron supralaeve is essential for optimal growth and flowering. Using a balanced, water-soluble fertilizer, such as a 20-20-20, every two weeks during the growing season is recommended. It's best to avoid fertilizing during the dormant season. Over-fertilizing can lead to burned roots, so it's important to follow the recommended dosage on the label.Pruning
Pruning is not necessary for Pachidendron supralaeve, but it can be done to control the plant's size and shape. Pruning should be done during the growing season, and it's best to remove no more than a third of the plant's foliage at a time. Pruning can also encourage new growth and promote a fuller plant. It's best to use sharp pruning shears or scissors and to sanitize them between each cut to prevent the spread of disease.Propagation Methods for Pachidendron supralaeve
Pachidendron supralaeve is a beautiful and exotic orchid plant commonly known as the Butterfly Orchid. It is native to Southeast Asia and is highly valued for its unique appearance and long-lasting flowers. Propagation is the process of creating new plants from existing ones, and Pachidendron supralaeve can be propagated through several methods.
Division
One of the easiest and most common ways to propagate Pachidendron supralaeve is through division. This method involves separating the plant's pseudobulbs, which are the small, bulb-like structures that store water and nutrients. To do this, carefully remove the plant from its pot and gently separate the pseudobulbs, making sure each section has a good root system. The new plant can be potted in fresh, well-draining soil and kept in a warm, humid location until it starts to grow.
Seed Propagation
Another way to propagate Pachidendron supralaeve is through seed propagation. This method requires more patience and expertise, as seeds can be finicky and slow to germinate. To start, collect the plant's seed pods when they are mature and brown. Sow the seeds in a mixture of orchid bark and perlite, and cover them lightly with soil. Keep the soil moist and warm, ideally between 68-77°F, and be patient as it may take several weeks to months for the seeds to germinate.
Meristem Culture
The final method of propagating Pachidendron supralaeve is through meristem culture. This method involves taking a small piece of stem tissue from the plant and growing it in a sterile, nutrient-rich culture. The tissue eventually grows into a new plant, which can then be transferred to soil once it has established roots. Meristem culture is a more advanced technique that requires specialized equipment and knowledge, and is often used by growers looking to produce large numbers of plants.
Overall, Pachidendron supralaeve is a beautiful and unique orchid plant that can be propagated through several methods. Division is the easiest and quickest option, while seed propagation and meristem culture are more advanced techniques that require more patience and expertise.
Disease Management
Pachidendron supralaeve is generally a hardy plant and is not vulnerable to many diseases.
However, occasionally, fungal diseases such as leaf spot and root rot may attack this plant. Leaf spot causes irregular patches of light to dark brown on leaves, while root rot appears as blackened, mushy roots.
To manage these diseases, it is important to ensure good drainage to prevent the accumulation of excess water around the roots. Pruning the plant to improve air circulation and removing affected leaves can also be helpful. Applying fungicides also helps in controlling the spread of fungal diseases.
Pest Management
Pests are not a significant issue for Pachidendron supralaeve, but the plant may occasionally be attacked by mealybugs, spider mites, and scale insects.
Mealybugs can be identified by the white, cottony masses they leave on leaves, while spider mites and scale insects attack the leaves and stems of the plant, causing them to turn yellow and wilt.
To manage these pests, regular cleaning of the plant leaves and stem using a soft, damp cloth is beneficial. You may also introduce natural predators such as ladybugs, which feed on mealybugs and other pests. Insecticides can also be used to control the spread of these pests.
It is essential to ensure proper cultural practices such as providing adequate light, water, and nutrients to the plant, which can help prevent pest infestation.
