Light Requirements
Rangaeris biglandulosa Summerh. is an epiphytic orchid that requires bright but indirect sunlight. Direct sunlight can scorch the leaves, while insufficient light can result in poor growth and insufficient blooming. The plant flourishes in an east or west-facing window with exposure to sunlight for 4-6 hours per day.
Temperature Requirements
Rangaeris biglandulosa Summerh. is a tropical plant that thrives in warm temperatures ranging between 18-29°C (65-85°F). During the day, the plant requires a temperature range of 21-26°C (70-80°F), while at night, the temperature should not fall below 18°C (65°F). Low temperatures can cause stunted growth, while excessively high temperatures can damage the plant.
Humidity Requirements
The plant requires high humidity of around 60-80% to thrive. Therefore, it requires regular misting or placement in a humid environment. In addition, proper ventilation is necessary to prevent fungal and bacterial growth due to excessive moisture.
Soil Requirements
Rangaeris biglandulosa Summerh. is an epiphytic orchid plant that does not require soil. Instead, it prefers a well-draining, coarse potting mix that replicates its natural environment. A combination of bark, sphagnum moss, and perlite is suitable for potting. The orchid should be watered thoroughly and allowed to drain before being returned to its elevated position.
Cultivation
Rangaeris biglandulosa Summerh. is an epiphyte orchid plant that requires proper care for proper growth. It can be grown in pots or mounted on driftwood or tree ferns. When grown in a pot, it requires special orchid potting soil or mix and should be mounted in a pot with a drainage hole to prevent waterlogging.
The plant prefers bright, indirect light, and temperatures between 60°F and 80°F. It can thrive under high humidity levels and good air circulation to ensure proper growth and blooming.
Watering
Rangaeris biglandulosa Summerh. requires adequate watering to develop and grow. The plant should be watered thoroughly and allowed to dry out before the next watering. It is essential to ensure that the roots do not stay too wet, as this can lead to root rot.
The plant should be watered using distilled, rainwater, or tap water that has been allowed to sit for at least 24 hours to remove any chlorine content. The frequency of watering should be adjusted based on the temperature and humidity levels in the environment.
Fertilization
Regular fertilization is essential to promote growth and ensure the plant has enough nutrients to support its development. Rangaeris biglandulosa Summerh. can be fertilized using liquid orchid fertilizers, which can be applied every two to three weeks during the growing season.
It is important to follow the recommended dosage and dilution instructions on the fertilizer package. During the winter months, fertilization can be reduced or suspended to allow the plant to rest.
Pruning
Pruning is essential to ensure that the plant maintains its shape, size, and health. The plant should be pruned after flowering, and any damaged or dead growth should be removed.
The flower spikes should also be cut back to promote new growth and re-blooming. The plant can be divided every few years to prevent overcrowding and promote new growth and bloom.
Propagation of Rangaeris biglandulosa Summerh.
Rangaeris biglandulosa Summerh. is a species of orchid that grows in the rainforests of West and Central Africa. The plant is known for its beautiful pink and white flowers and is a popular choice among orchid enthusiasts. Propagation of Rangaeris biglandulosa Summerh. can be done through different methods including:
Seed Propagation
One of the most common ways of propagating Rangaeris biglandulosa Summerh. is through seeds. However, due to the difficulty of obtaining viable seeds, this method is not widely used among growers. Seeds must be harvested when the seed pod has turned brown and begun to split, and the seeds must be sown immediately because they lose viability quickly. It is essential to use a sterile growing medium that is well-draining. Planting the seeds in a small pot that is covered with plastic wrap and kept in a warm and bright spot can help to increase the chances of germination.
Division
Division is another method of propagating Rangaeris biglandulosa Summerh. and is commonly used by growers. This method involves dividing the plant into smaller sections, each with its own growing point. Division is best done during the plant's active growth period when new shoots are starting to develop. The plant should be carefully removed from the pot and gently teased apart into smaller sections, making sure that each section has some roots and leaves. The divisions can then be potted in individual containers and kept in a warm, moist and bright spot until they become established.
Cloning
Cloning or tissue culture is a method of propagation that is used for commercial purposes as it allows mass production of identical plants. This method involves taking a small section of the plant and growing it in a nutrient-rich, sterile, and controlled environment. Tissue culture requires specialized equipment and expertise and is not recommended for novice growers.
Propagation of Rangaeris biglandulosa Summerh. can be a rewarding experience for orchid enthusiasts. By selecting the right method for your needs and following the correct techniques, you can increase your success rate and enjoy the beauty of this magnificent plant.

Diseases
Bacterial spot: This disease is identified by the presence of small, water-soaked lesions that eventually become sunken and turn brown. Bacterial spot can cause the leaves of your Rangaeris biglandulosa Summerh. plant to wilt and die. To prevent this disease, avoid overhead watering. Use a copper-based fungicide if the disease has already infected the plant.
Root rot: Root rot is caused by a fungus that thrives in moist soil. Symptoms of this disease include yellowing of leaves, wilting, and soft roots. To manage root rot, remove the infected plant from its pot and shake the soil off the roots. Cut away any soft or rotten roots and repot the plant in fresh, well-draining soil.
Fungal leaf spot: Fungal leaf spot is characterized by brown spots on the leaves that have a yellow or black margin. To prevent this disease, avoid overhead watering and improve air circulation around your Rangaeris biglandulosa Summerh. plant. If the disease has already infected the plant, remove the affected leaves and apply a fungicide.
Pests
Spider mites: Spider mites are tiny pests that suck the sap out of your Rangaeris biglandulosa Summerh. plant. You can identify them by the presence of tiny webs on the leaves of your plant. To get rid of spider mites, isolate the infected plant from other plants and spray it with insecticidal soap or neem oil regularly.
Scale insects: Scale insects are small, armored pests that suck the sap out of your plant, causing it to weaken and eventually die. They can be removed by using a cotton swab soaked in rubbing alcohol to wipe off the scales or by applying a systemic insecticide.
Mealybugs: Mealybugs are small, cotton-like pests that usually hide under the leaves and feed on your Rangaeris biglandulosa Summerh. plant. They can be removed by wiping the leaves with a cotton swab dipped in rubbing alcohol or by applying a systemic insecticide.
By keeping an eye out for these common diseases and pests and implementing the suggested management techniques, you can keep your Rangaeris biglandulosa Summerh. plant healthy and beautiful.
