Angraecum occidentale requires high levels of light to grow and thrive. They need to be exposed to bright, filtered light with direct sunlight only in the early morning or late afternoon. Too much direct sunlight can scorch the leaves, causing them to turn yellow and fall off.
Temperature Requirements
The optimal temperature range for Angraecum occidentale is between 20°C and 30°C (68°F-86°F) during the day and a low of 15°C (59°F) at night. They are tolerant of a wide range of temperatures, but growth may slow down at temperatures beyond this range.
Soil Requirements
Angraecum occidentale is a epiphytic orchid that grows attached to trees in the wild. They do not grow well in soil, but instead, require a well-draining medium that mimics the bark of trees. Ideal potting media is a mixture of fine bark, perlite, and sphagnum moss that retains some moisture while providing enough air circulation.
Cultivation methods
Angraecum occidentale is an orchid species native to Cameroon, Equatorial Guinea, and Nigeria. It can be grown indoors in temperate regions or in a greenhouse.
The best way to grow this plant is in a basket, hanging from the ceiling, or on a support like a piece of wood or tree fern. The roots are slender and must have access to air, so the porous environment of bark or moss is suitable for cultivation, but overcrowding must be avoided. Additionally, the plant prefers bright, indirect light and temperatures between 60 and 80 degrees Fahrenheit.
Watering needs
Angraecum occidentale is also a relatively drought-tolerant orchid, so it is essential to avoid over-watering. During the growing season, watering once a week is enough, while in the dormant season, watering should be reduced to once every ten days. The potting medium must be completely dried out between watering cycles to ensure the root zone’s good health.
Fertilization
The plant's roots are particularly sensitive to the soil's nutrient content and pH level, use a balanced fertilizer with an equal ratio of nitrogen, phosphorus, and potassium and diluted to half the rate recommended on the bottle. Additionally, the recommended pH is nearly neutral or slightly acidic between 6.0 to 6.5.
Pruning
Regular pruning of Angraecum occidentale is not essential, but remove withered or damaged foliage, flowers, and air roots. Keep the leaves clean and free of pests by wiping them with a damp cloth. It would be best if you also kept an eye for pests, especially scale and spider mites, to catch infestations early and apply the necessary pesticides immediately.
Propagation of Angraecum occidentale (Kraenzl.) Rolfe
Angraecum occidentale (Kraenzl.) Rolfe, commonly known as Western Angraecum, is a species of orchid that is native to the African continent. This exotic plant is a popular ornamental plant due to its unique tubular flowers and small stature. It is a relatively hardy plant, making it suitable for novice gardeners. The following are the different propagation methods that can be used to propagate Angraecum occidentale:
Division
Division is one of the most common and straightforward propagation methods for Angraecum occidentale. This method is best carried out during spring, when the plant is just beginning to show new growth. To propagate through division, remove the plant from its container and gently separate the roots and leaves using a clean, sharp knife or scissors. Be sure to maintain the integrity of each new plant by ensuring that each section has enough roots and leaves. Afterward, you can place each new plant back into its pot with fresh soil and water.
Kikuyu grass Layering
Kikuyu layering is a propagation technique that involves burying the base of the mother plant within kikuyu grass and cutting it away from the mother plant once it has rooted. Although not a common propagation method, it can be successful for Angraecum occidentale. To propagate using this technique, first, bury horizontal stems of the plant into the ground while still attached to the mother plant. Next, cover the horizontal stems with kikuyu grass and water frequently to encourage the new plant to take root. Once stems have taken root, cut them away from the mother plant and transplant them to individual pots to grow further.
Keiki Paste
Keiki paste is a hormonal paste that can stimulate the development of new shoots and buds from the nodes of a plant. This technique is typically used on orchids but can be effective in propelling Angraecum occidentale. Keiki paste must be carefully applied to the node of the plant, and the developing bud must be monitored closely for signs of development. Once cut away from the mother plant, the new plant must be transplanted to its new container and maintained with proper care.
Regardless of the propagation method chosen, it is essential to provide the new plants with optimal growing conditions such as high humidity and warm temperatures to ensure its continued growth and development.
Disease and Pest Management of Angraecum Occidentale
Angraecum occidentale, also known as the West Indian orchid, is a beautiful species of orchid that is native to the West Indies and parts of South America. Like all plants, it is susceptible to various pests and diseases that can damage or even kill the plant. Here are some of the most common problems that can affect Angraecum occidentale and how to manage them.
Common Pests
One common pest that can affect Angraecum occidentale is the scale insect. These insects suck sap from the plant, causing it to weaken and become more vulnerable to disease. They also produce a sticky substance called honeydew, which attracts other pests such as ants and sooty mold. To manage scale insects, you can use an insecticidal soap or oil to suffocate them. You can also use a soft-bristled brush to remove them manually.
Another common pest that can affect Angraecum occidentale is the spider mite. Like the scale insect, spider mites also suck sap from the plant, causing it to weaken and become more vulnerable to disease. They are very small and difficult to see, but you can detect their presence by the presence of fine webs on the plant. To manage spider mites, you can use a miticide or insecticidal soap. You can also increase the humidity around the plant to discourage their growth.
Common Diseases
Angraecum occidentale can also be susceptible to various fungal and bacterial diseases, especially if the plant is exposed to too much moisture or is overcrowded. One common disease is black rot, which produces black, mushy lesions on the leaves and stems. To manage black rot, you can remove the affected parts of the plant and avoid getting water on the leaves and stems.
Another common disease is root rot, which occurs when the roots become waterlogged and begin to rot. To manage root rot, you can repot the plant in fresh, well-draining soil and allow it to dry out before watering it again.
Preventative Measures
One of the best ways to manage pests and diseases in Angraecum occidentale is to prevent them from occurring in the first place. This can be done by keeping the plant in good health, providing adequate light, water, and humidity, and avoiding overcrowding. You should also inspect the plant regularly for signs of pests and disease and take action immediately if you detect any problems.
In summary, Angraecum occidentale can be susceptible to various pests and diseases, but with proper management and preventative measures, you can keep your plant healthy and beautiful for years to come.
