Overview
Aerangis biloboides, also known as Angraecum biloboides or Aerangis coriacea, is a species of orchid that belongs to the family Orchidaceae. This plant is native to Africa and can be found in countries like Cameroon, Gabon, and the Republic of Congo.Common Names
Some of the common names for Aerangis biloboides include the Two-Lobed Aerangis and the Tough-Textured Aerangis.General Appearance
Aerangis biloboides is a small to medium-sized epiphytic plant that can grow up to 15 cm in height. It has clustered stems that are elongated and slender. The leaves are thick and fleshy, green in color, and arranged spirally along the stem. The plant produces a single flower stalk that arises from the base of the stem, which can bear up to six small flowers.Uses
Aerangis biloboides is primarily grown as an ornamental plant due to its attractive appearance. It has a long flowering season, producing flowers that are fragrant, white, and waxy in texture. This plant can be grown in a pot or mounted on a piece of bark, making it a versatile addition to any collection of orchids. Additionally, some of the species of Aerangis are used in traditional medicine for their medicinal properties, but there is little evidence to support these claims. In summary, Aerangis biloboides is a beautiful and adaptable orchid species that is widely grown for ornamental purposes. Its clustered stems, fleshy leaves, and fragrant flowers make it a stunning addition to any garden.Light Requirements
Aerangis biloboides requires bright, indirect light for optimal growth. This orchid should be protected from direct sunlight, as it can scorch the leaves and petals. This plant should be kept near a window with a sheer curtain that will provide it with filtered light throughout the day. East-facing windows are ideal for this plant.
Temperature Requirements
This orchid prefers temperatures that mimic the conditions of its natural habitat. During the day, the temperature should be between 21 to 29°C (70 to 85°F), while at night the temperature should drop to 10 to 18°C (50 to 65°F). These fluctuations in temperature help this plant thrive and encourage it to produce flowers.
Soil Requirements
Aerangis biloboides is an epiphytic orchid that grows on trees and rocks. As such, it requires a well-draining soil mixture that will not hold onto moisture for extended periods. A mixture of medium-grade bark, sphagnum moss, and perlite is ideal for this plant. This mixture will provide ample air circulation to the roots, preventing root rot and fungal growth. This orchid prefers to be slightly moist but not waterlogged.
Cultivation Method
Aerangis biloboides is an epiphytic orchid species that requires specific growing conditions. It is native to central Africa and requires warmth, medium light, and high humidity. Growing Aerangis biloboides may require adding a host tree or growing on a tree fern slab, then you can hang it on a shade house.
Watering Needs
Watering Aerangis biloboides can be tricky since it is susceptible to root rot. It is essential to maintain medium moisture throughout the growing season, and mist frequently during dry or low-humidity periods. Water a little less during the winter season when the plant becomes dormant.
Fertilization
Regular fertilization is also essential when attempting to grow the Aerangis biloboides. Apply a balanced orchid fertilizer to the roots or foliage weekly during the growing season. Dilute the fertilizer to half the recommended strength and make sure not to over-fertilize.
Pruning
When pruning Aerangis biloboides, you need to ensure adequate air circulation between the leaves to prevent fungal and bacterial infections. Remove any dead or diseased leaves with sterilized cutting tools. You can also trim longer leaves and flower stalks after they have bloomed. This prevents the plant from using its energy on an unnecessary part, thus focusing its energy on developing new growth.
Propagation of Aerangis biloboides
Propagation of Aerangis biloboides can be done through various methods, including:
Seed Propagation
The most common method of propagating Aerangis biloboides is through seed propagation. The seeds of the plant are small and require a delicate touch to handle. Sowing them in a well-draining medium, such as sphagnum moss or fine bark, is recommended. The seeds almost always require the presence of a fungus to germinate. This fungus helps the seed absorb nutrients from its surroundings and generally takes several weeks to establish. Seedlings require constant monitoring and appropriate watering and fertilization.
Division
Another method of propagating Aerangis biloboides is through division. This method involves dividing the plant into multiple sections and potting them into individual containers. It's best to do division when the plant is actively growing, and the roots are well-established. The divided sections should be promptly repotted and maintain appropriate care for the next few weeks until they are adequately established.
Stem Cuttings
Stem cuttings can also be used to propagate Aerangis biloboides. This method involves taking a stem cutting and planting it in a well-draining medium. The cutting should be taken from actively growing stem with at least two nodes. It's also recommended that the cutting be treated with a rooting hormone to encourage root development. The cutting should be monitored continuously and regularly watered and fertilized until it is established.
Disease Management
One common disease that can affect Aerangis biloboides is black rot. This disease is caused by the fungus Phytophthora cactorum and can be identified by blackened, mushy stems and leaves. To manage black rot, it is important to regularly inspect your plant for any signs of infection and remove any infected parts immediately. Ensure that the plant is not overwatered and that there is adequate air circulation around the plant. Fungicides can also be used as a preventative measure.
Another disease that can affect Aerangis biloboides is leaf spot. This disease is caused by the fungus Cercospora and can be identified by brown, necrotic spots on the leaves. To manage leaf spot, it is important to remove any infected leaves and improve air circulation around the plant to reduce humidity. Fungicides can also be used as a preventative measure.
Pest Management
The most common pest that can affect Aerangis biloboides is the mealybug. Mealybugs can be identified by their white, cotton-like appearance and can cause damage to the plant by sucking the sap from the leaves and stems. To manage mealybugs, it is important to regularly inspect your plant for any signs of infestation and remove any mealybugs manually. Insecticidal soaps or oils can also be used as a treatment.
Spider mites can also be a pest that can affect Aerangis biloboides. These pests are tiny and can cause damage by sucking the chlorophyll from the leaves, resulting in yellowing of the leaves. To manage spider mites, it is important to improve air circulation around the plant and clean the leaves regularly with water to remove any dust or debris. Insecticidal soaps or oils can also be used as a treatment.
