Overview
Bulbophyllum elongatum, also known as the African Bulbophyllum, is a species of orchid that is native to central and western Africa.
Description
The plant has a creeping habit and grows to a length of up to one meter. It produces a large number of small, unobtrusive flowers that are purple and yellow in color. Bulbophyllum elongatum has pseudobulbs - a specialized storage organ - that are brownish-red in color and approximately one inch in length. Each pseudobulb can produce one or two long green leaves that are up to ten inches in length.
Common Names
Bulbophyllum elongatum is commonly referred to as the African Bulbophyllum, Pseudobulbous Bulbophyllum, or the Orchid’s Orchid.
Uses
Bulbophyllum elongatum is primarily grown as an ornamental plant and is a popular choice for those who adore orchids. It is cultivated by collectors and orchid lovers because of its delicate and exotic flowers that bloom year-round.
Light Requirements
Bulbophyllum elongatum plants require bright, indirect light for healthy growth. Direct sunlight can burn the leaves. Therefore, a shaded area with filtered light or artificial light is ideal for these plants.
Temperature Requirements
The ideal temperature range for Bulbophyllum elongatum plants is between 20°C and 30°C. These plants require a warm and humid environment to thrive. They can tolerate slightly cooler temperatures, but they do not do well in temperatures below 15°C.
Soil Requirements
Bulbophyllum elongatum plants need well-draining soil that retains some moisture, but not too much. These plants grow naturally on tree trunks or rocks in their native habitat. Therefore, they require a mix of coarse bark, perlite, sphagnum moss, and charcoal to provide good drainage and aeration.
Cultivation methods for Bulbophyllum elongatum
Bulbophyllum elongatum is a terrestrial species that grows well in well-draining soil. Careful soil selection and preparation are essential to successful cultivation. A combination of peat, perlite, and charcoal is recommended for optimal growth. A layer of coarse gravel can help improve drainage, and the pot should be large enough to allow space for the roots to grow.
This plant thrives in warm temperatures and high humidity. In optimal conditions, it can grow up to a foot tall and produce numerous small, fragrant flowers. A mixture of sphagnum moss and charcoal can be used to simulate the high humidity levels that Bulbophyllum elongatum prefers.
Watering needs of Bulbophyllum elongatum
The watering needs of Bulbophyllum elongatum are unique. This plant is drought-tolerant and does not require frequent watering. Watering should only occur when the soil is completely dry; overwatering can cause root rot and damage the plant. It is best to water sparingly and allow the soil to dry out between watering sessions.
Fertilization of Bulbophyllum elongatum
Bulbophyllum elongatum is not a heavy feeder. However, it can benefit from occasional applications of fertilizers during the growing season. A balanced, water-soluble fertilizer that is high in nitrogen is recommended for optimal growth. Fertilization should be done around every two to three weeks, and the strength of the fertilizer should be diluted to avoid burning the roots.
Pruning Bulbophyllum elongatum
Pruning is not required for Bulbophyllum elongatum. However, pruning can be done to maintain the plant's shape and size. Trimming back dead or discolored leaves can help improve the plant's overall appearance and prevent the spread of diseases. It is important to use sterilized pruning tools to prevent infection.
Propagation of Bulbophyllum elongatum
Bulbophyllum elongatum (De Wild.) De Wild. is a terrestrial orchid native to Africa. Propagation of this plant is achievable through different methods such as rhizome division, keiki production, and seed.sowing.
Rhizome division
Rhizome division is the most common method of propagating Bulbophyllum elongatum. The best time to divide rhizomes is when the plant begins to grow and develop new roots. Cut the rhizome using a sharp and sterilized knife, making sure that every section has several growth shoots. Then, replant the divided rhizomes in a suitable potting mix.
Keiki production
Keiki production is an asexual propagation method where a plant produces small clones of itself. With Bulbophyllum elongatum, keiki production occurs on the stem. Once the keiki has formed roots and shoots, it can be detached from the mother plant and potted separately.
Seed sowing
Propagation by seed is an alternative method to produce Bulbophyllum elongatum. To grow this plant from seed, use sterile potting mix and sow seeds onto the surface of the medium. Cover the seeds with a thin layer of medium and place them under shade and warm conditions. During the germination process, the humidity level must be around 80%. Once the seedlings have developed enough, they can be transplanted into individual pots.
Disease and Pest Management for Bulbophyllum elongatum (De Wild.) De Wild.
Bulbophyllum elongatum (De Wild.) De Wild. is a popular orchid species known for its long, delicate flowers and attractive foliage. However, like any other plant, this species is at risk of being attacked by pests and diseases that can compromise its health and appearance.

Here are some common pests and diseases that might affect the plant and the best ways to manage them.
Pests
Some common pests that can infest Bulbophyllum elongatum (De Wild.) De Wild. include:
- Scale Insects: Scale insects are sap-sucking insects that can cause yellowing and wilting of the leaves. You can manage scale insects by removing them with a soft brush or cloth and spraying the plant with insecticidal soap or neem oil.
- Spider Mites: Spider mites are tiny pests that can cause discoloration of the leaves, webbing, and stunted growth. You can manage spider mites by spraying the plant with water to dislodge them and using insecticidal soap or neem oil.
- Mealybugs: Mealybugs are white, cottony insects that suck sap from the plant. They can cause wilting, yellowing, and stunted growth. You can manage mealybugs by removing them with a soft brush or cloth and spraying the plant with insecticidal soap or neem oil.
Diseases
Some common diseases that can affect Bulbophyllum elongatum (De Wild.) De Wild. include:
- Black Rot: Black rot is a fungal disease that causes brown or black spots on the leaves, stems, and flowers. The affected parts of the plant may have a foul odor. You can manage black rot by removing the affected parts of the plant, improving air circulation, and avoiding overwatering.
- Root Rot: Root rot is a fungal disease that causes the roots to rot and the plant to wilt and die. You can manage root rot by avoiding overwatering, improving soil drainage, and using a well-draining potting mix.
- Leaf Spot: Leaf spot is a fungal disease that causes small, circular spots on the leaves. The spots may be yellow, brown, or black. You can manage leaf spot by removing the affected leaves, improving air circulation, and avoiding overhead watering.
By taking proper care of your Bulbophyllum elongatum (De Wild.) De Wild. plant, you can prevent most problems caused by pests and diseases. Provide the plant with adequate light, proper humidity, and good air circulation to help it grow healthy and strong.
