Specifically, it is thought to aid in the treatment of various respiratory conditions, including asthma. It is also used to treat liver and stomach problems. In addition, the fragrant flowers of the plant are used to produce perfume.
Light Requirements
Angraecum schimperianum requires bright but indirect light to grow and thrive. It is recommended to place the plant in a location with filtered or diffused light. Direct sunlight can scorch the leaves and damage the plant.
Temperature Requirements
The ideal temperature range for Angraecum schimperianum is 60-80°F (15-27°C). The plant can tolerate slightly cooler temperatures at night but should not be subjected to temperatures below 50°F (10°C). High temperatures above 85°F (29°C) can cause damage and should be avoided.
Soil Requirements
Angraecum schimperianum is an epiphytic plant, which means it grows naturally on other plants rather than in soil. Therefore, it does not have specific soil requirements. However, it should be planted in a well-draining medium that is airy and provides good water retention. A typical mixture for orchids, such as bark, coconut coir, or sphagnum moss, is suitable. It is essential to use a medium that allows the roots to breathe and does not retain too much moisture, as this can lead to root rot.
Cultivation Methods
Angraecum schimperianum (A.Rich.) Rchb.f. is an epiphyte orchid species, which means it grows on tree branches in its natural habitat. Therefore, it is essential to replicate its natural surroundings by placing it in a pot that resembles a tree branch or attaching it to a piece of driftwood. An ideal potting medium for this orchid should consist of small-sized bark, sphagnum moss, and perlite, which provides good drainage and adequate aeration. Angraecum schimperianum (A.Rich.) Rchb.f. requires bright, indirect light and warm temperatures in the range of 18-28°C.
Watering Needs
Angraecum schimperianum (A.Rich.) Rchb.f. prefers to be moist for most of the time but without getting waterlogged. Its most effective watering technique involves immersing the pot in a bucket of water and allowing it to soak for up to an hour. Then, take out the pot and let it drain until there is no more dripping. It is better to water this orchid adequately once every five to seven days rather than misting or spraying daily.
Fertilization
Like most orchids, Angraecum schimperianum (A.Rich.) Rchb.f. requires a balanced fertilizer with an NPK ratio of 20-20-20. Using a concentrated solution of fertilizer is not recommended, as it can cause severe root damage. Instead, dilute the fertilizer in water and apply it at half or quarter strength once every two weeks during the growing season and reduce it to once every month during the dormant season.
Pruning
Angraecum schimperianum (A.Rich.) Rchb.f. does not require frequent pruning, but you can cut off damaged, dried, or yellowing leaves to maintain the plant's overall health. It is advisable to use sharp and sterilized scissors or pruning shears, preferably with a disinfectant solution such as rubbing alcohol. Avoid cutting off the green leaves as they are crucial for the plant's photosynthesis and food production.
Propagation of Angraecum schimperianum (A.Rich.) Rchb.f.
Propagation of Angraecum schimperianum can be done through various methods, including seed propagation, division, and stem cuttings. Each method has its own advantages and disadvantages, and the choice of method depends on various factors, such as the availability of plant material and the grower's expertise.
Seed Propagation
Angraecum schimperianum can be propagated by seed, which is the most common method. The seeds can be collected from the mature orchid plant during the fruiting season and sown immediately after harvesting. The seeds are very tiny and must be sown thinly on the surface of a sterile moist medium, such as sphagnum moss or a mixture of perlite and peat moss. The container must be sealed and placed in a warm bright location but out of direct sunlight. Germination can take up to several months, and it is essential to keep the seedlings in high humidity and low light until they are large enough to be potted.
Division
Division is a viable propagation method for Angraecum schimperianum, but it can only be used when the orchid plant has grown large enough to develop well-defined pseudobulbs. This method involves carefully removing the plant from its pot and dividing the root ball into smaller sections, ensuring that each section has at least one healthy pseudobulb and a few roots. Each division should be planted in a pot filled with a well-drained medium and kept in a warm, humid location until new growth appears.
Stem Cuttings
Propagation by stem cuttings is not a common method for Angraecum schimperianum because the orchid plant does not produce many stems. However, if a stem is cut, the cuttings should be at least 5-6 inches long and should contain one or two nodes. The bottom node should be dipped in rooting hormone and inserted into a well-draining medium. The container should be covered, and the cutting should be kept in a warm, humid place. Rooting can take a few weeks to a few months, and the cutting should only be transplanted to a bigger pot when new growth appears.
