Origin
Bulbophyllum velutinum, also known as the Velvet Bulbophyllum, is a species of orchid native to Southeast Asia. It is found in countries such as Thailand, Malaysia, Indonesia, and the Philippines, growing in lowland forests at elevations of up to 500 meters above sea level.
Common Names
Aside from Velvet Bulbophyllum, this plant is also known by other common names such as Hairy Bulbophyllum and Hairy Orchid.
Uses
Bulbophyllum velutinum is mainly cultivated for its ornamental value. Its unique appearance makes it a popular addition to indoor gardens and terrariums. Some orchid enthusiasts also grow this plant as part of their collection. However, this plant doesn't have any known medicinal or culinary uses.
General Appearance
Bulbophyllum velutinum is a small and compact orchid species that grows up to 15 centimeters in height. Its pseudobulbs are small and cylindrical, measuring 1 to 2 centimeters in diameter. The leaves are oval-shaped and grow up to 10 centimeters in length. They are dark green with a glossy surface and covered in fine hairs on the underside, hence the name "Velvet Bulbophyllum." The flowers, which only last for a few days, grow in clusters of up to 15 on each spike. They are small, measuring around 1.5 centimeters in diameter, and have a yellow-green color with reddish-brown stripes. Bulbophyllum velutinum blooms throughout the year, making it a great addition to any indoor garden.
Light conditions
Bulbophyllum velutinum requires bright, but indirect light for growth. Direct sunlight can burn its delicate leaves and hinder its growth. Placing the plant near an east or west-facing window where it can receive bright, filtered light for a few hours a day is ideal.
Temperature requirements
Bulbophyllum velutinum thrives in warm and humid environments. The ideal temperature range for this plant is between 20°C to 30°C (68°F-86°F) during the day and above 16°C (60°F) at night. The plant should be kept away from drafty areas and cold windows.
Soil requirements
Bulbophyllum velutinum is an epiphytic orchid, meaning it grows on other plants instead of in soil. It requires a well-draining potting mix with good aeration, such as fir bark, sphagnum moss, or perlite. It is important to ensure the potting mix is not allowed to dry out completely between watering, as this can cause damage to the delicate roots.
Cultivation Methods for Bulbophyllum velutinum
Bulbophyllum velutinum is an epiphytic orchid that requires a warm and humid environment to grow and thrive. The plant prefers to grow in well-draining soil, with medium to bright indirect sunlight. It can also grow in a semi-hydroponic setup or mounted on a tree bark or a piece of driftwood.
Watering Needs for Bulbophyllum velutinum
The Bulbophyllum velutinum requires regular watering, with its roots kept moist but not waterlogged. The frequency of watering increases during the growing season in summers and decreases in winters when the plant enters its dormant phase. It is necessary to avoid wetting the foliage as it can lead to fungal diseases.
Fertilization for Bulbophyllum velutinum
The Bulbophyllum velutinum requires a balanced fertilizer, with a higher nitrogen content during the active growing season. Fertilize the plant once every two to three weeks during the spring and summer growing season. Reduce the fertilization frequency to once a month during the dormant winter season.
Pruning for Bulbophyllum velutinum
The Bulbophyllum velutinum does not require frequent pruning. Remove any yellow, brown, or dead leaves, flowers, and aerial roots as soon as possible. It is necessary to inspect the plant regularly to identify any pest or disease issues. Trim off any affected parts as soon as they are identified to avoid the spread of the infestation.
Propagation of Bulbophyllum velutinum (Lindl.) Rchb.f.
Bulbophyllum velutinum (Lindl.) Rchb.f., also known as the velvety bulbophyllum, is a beautiful epiphytic or lithophytic orchid that originates from the Southeast Asian countries of Thailand, Laos, Vietnam, and Cambodia. The plant is loved for its stunning and fragrant flowers that can be long-lasting when given proper care and maintenance.
Propagation of Bulbophyllum velutinum can be carried out through different methods, including:
Division
Division is one of the easiest and most common methods of propagating Bulbophyllum velutinum. To do this, carefully remove the plant from its pot and gently separate the pseudobulbs. The ideal time to divide the plant is during repotting when the roots are strong enough. Once divided, plant each portion in a fresh pot with a suitable orchid growing mix.
Keiki Production
Bulbophyllum velutinum can produce keikis or baby plants along the flowering stem. Keikis can be removed after they have grown roots, as these indicate that they are strong enough to grow into a new plant. Cut the keiki off from the main plant, ensuring that you have a sufficient number of roots, and then pot it in a suitable orchid growing mix. Keikis usually produce a new plant faster than division.
Seed Propagation
Bulbophyllum velutinum can be propagated through seeds, although this method requires expertise and patience as it can take several years for the orchid to mature and start producing flowers. The seeds should be sown in a favorable growing substrate and kept moist but not waterlogged.
In conclusion, propagating Bulbophyllum velutinum can be achieved through division, keiki production, and seed propagation. Each method has its advantages and disadvantages, so choose the one that best suits your needs and gardening skills.
Disease and Pest Management for Bulbophyllum velutinum
Bulbophyllum velutinum (Lindl.) Rchb.f. is a beautiful orchid species that is commonly grown for its attractive flowers. However, like all plants, it is susceptible to certain diseases and pests that can affect its growth and overall health. Here are some common diseases and pests that might affect this plant along with suggestions for their management.
Diseases
1. Bacterial Soft Rot: This is a common disease that affects Bulbophyllum velutinum, especially when the plant is grown in excessively moist conditions. The symptoms include soft, water-soaked lesions on the leaves and pseudobulbs, which quickly turn mushy and emit a foul odor. To manage this disease, remove the infected parts of the plant, improve the air circulation around the plant, and avoid watering the plant excessively.
2. Anthracnose: This is another fungal disease that affects the leaves and blooms of Bulbophyllum velutinum. It appears as dark, sunken spots on the leaves, stems, and flowers that gradually enlarge and affect larger areas. To manage this disease, remove the infected parts of the plant and avoid getting water on the leaves and flowers. Also, ensure that you space your plants appropriately to facilitate good air circulation.
Pests
1. Scale insects: Scale insects are common pests that suck sap from Bulbophyllum velutinum, leaving a sticky honeydew on the foliage. This can make the plant appear unsightly and can lead to fungal infections. To manage scale insects, use a soft-bristled brush to remove them from the leaves and stems or apply insecticidal oils or soap sprays.
2. Spider mites: Spider mites are tiny pests that can cause the leaves of Bulbophyllum velutinum to appear stippled. If left unchecked, they can cause the leaves to turn brown and fall off. To control spider mites, spray the plant with a strong jet of water to dislodge them from the leaves and use insecticidal soaps or oils to manage heavy infestations.
By following these simple disease and pest management practices, you can keep your Bulbophyllum velutinum healthy and thriving for years to come.
