It belongs to the genus Angraecum which is the largest genus in the subfamily Vandoideae. Angraecum backeri Kraenzl. is a rare orchid and is considered endangered in the wild due to habitat loss and over-collection.
Common Names of Angraecum backeri Kraenzl.
The common name for Angraecum backeri Kraenzl. is Bäcker's Angraecum.
Uses of Angraecum backeri Kraenzl.
Angraecum backeri Kraenzl. is highly coveted by collectors because of its beauty and rarity. It is commonly grown as an ornamental plant for its showy flowers. The plant has also been studied for its medicinal properties as some members of the Angraecum genus have been found to contain compounds that are effective against human cancer cells. However, further research is needed to determine the full potential of Angraecum backeri Kraenzl. in medicine.
Appearance of Angraecum backeri Kraenzl.
Angraecum backeri Kraenzl. is an epiphytic orchid that grows on trees and other plants. It has pendant roots that attach to the host plant. The plant has long, narrow leaves that can grow up to 30 cm in length. The flowers are greenish-white and have a star-shaped appearance. They have a sweet, pleasant fragrance and can grow up to 2.5 cm in diameter. The plant can reach a height of 30-40 cm when mature and blooms in the summer.
Light Requirements
Angraecum backeri Kraenzl. needs bright, filtered light to thrive. Direct sunlight can scorch its leaves, but too little light can slow its growth. It is recommended to place the plant near east or west-facing windows, where it can receive bright but indirect light. If growing the plant indoors, artificial light can also be used.
Temperature Requirements
The plant prefers warm temperatures ranging from 60°F (16°C) to 80°F (27°C). It cannot tolerate frost and should be protected from temperatures below 50°F (10°C). Consistent temperatures and humidity levels are important for the growth of Angraecum backeri Kraenzl.
Soil Requirements
Like most epiphytic orchids, Angraecum backeri Kraenzl. grows best in a well-draining, loose, and porous soil mix that mimics its native natural habitat. A suitable potting mix can be made by combining a high-quality orchid bark, sphagnum moss, and perlite. It is recommended to avoid using regular potting soil or soil mixes that retain water.
Additionally, the plant can also be mounted on a piece of bark or a tree fern slab instead of being potted. This method mimics the plant's natural growing conditions and allows for good airflow around the roots, which aids in its growth.
Cultivation Methods
Angraecum backeri Kraenzl. is an epiphytic orchid that grows naturally in the highlands of Madagascar. To grow this plant successfully, it is crucial to mimic its natural growing conditions. Therefore, it is best to mount it on a piece of cork or bark, rather than planting it in soil or a pot. The plant needs to be kept in a well-ventilated area, preferably in a shaded spot. It is recommended to use a humidifier or place a tray of water near the orchid to maintain a humidity level between 50-70%.
Watering Needs
The Angraecum backeri Kraenzl. requires consistent watering, but overwatering can lead to root rot. It is best to water the orchid early in the morning to prevent water from sitting on the leaves and causing damage. The plant should be watered every 5-7 days, depending on the humidity level, with lukewarm water. Ensure that the roots are thoroughly soaked, then let the water drain out of the pot or off the bark mount. In the winter months, reduce the frequency of watering but do not let the orchid dry out completely.
Fertilization
The Angraecum backeri Kraenzl. does not require frequent fertilization, but occasional feeding can help the plant grow healthy and strong. Use a balanced orchid fertilizer, diluted in water, once every two weeks during the growing season (spring to summer). Reduce the frequency of fertilization during the dormant season (fall to winter). Avoid fertilizing on dry roots as it can cause damage to the plant.
Pruning
Pruning the Angraecum backeri Kraenzl. is not necessary unless there are dead or damaged parts of the plant. In that case, use sterilized pruning shears to remove the affected areas. It is essential to sterilize the tools before use to avoid transferring any disease or bacteria to the plant. Remove any dried or yellow leaves and discard them to keep the plant healthy and clean.
Propagation of Angraecum backeri Kraenzl.
Angraecum backeri Kraenzl. can be propagated through either seed propagation or vegetative propagation.
Seed Propagation
Seed propagation is the most commonly used method of propagating Angraecum backeri Kraenzl. This method involves collecting the seeds from the mature pods and sowing them in a suitable medium. Mature pods are normally brown and have begun to dry out and split, making the seeds visible and easy to extract. It may take several tries before you succeed in getting good germination rates.
The seeds should be sown in a well-draining and airy medium, as this orchid requires good air circulation around its roots. A recommended medium for the seed sowing is a mixture of fine bark, perlite, and sphagnum moss, in equal parts. Young seedlings may take up to two years to produce their first flowers.
Vegetative Propagation
Angraecum backeri Kraenzl. can also be propagated through vegetative propagation. This method involves dividing the plant's pseudo-bulbs and replanting them to establish new growth. This method is most effective in the spring when new growth appears, and the orchid has an active growing season.
To propagate using this method, carefully remove the plant from the pot and gently pull apart the pseudo-bulbs. It is best to make sure that each separated pseudo-bulb has several roots attached. Once separated, plant each pseudo-bulb in a suitable medium in separate pots. It is recommended to use a medium made of sphagnum moss or a mixture of fine bark and perlite. Keep the newly planted orchids in a warm, humid area with bright indirect light.
Disease Management for Angraecum backeri Kraenzl.
Angraecum backeri Kraenzl. is generally resistant to plant diseases. However, the plant may be vulnerable to some fungal and viral infections. These diseases can be managed by following a few steps:
- Avoid high humidity levels in the growing environment as it can encourage the growth of fungal spores.
- Maintain proper spacing between plants to avoid overcrowding and promote good air circulation.
- Rotate the plant among different locations to reduce the likelihood of the same pathogen infecting the same location the following year.
- Remove any infected plant material to prevent the spread of the disease.
- Apply fungicides to manage or prevent infections from occurring.
Pest Management for Angraecum backeri Kraenzl.
Angraecum backeri Kraenzl. is generally not prone to pest infestation. However, some pests may occasionally attack your plants. The following pests are most common:
- Spider mites
- Mealybugs
- Scale insects
You can manage or prevent infestations by:
- Regularly inspecting your plants for signs of pest damage.
- Introducing natural predators such as ladybugs or predatory mites to your growing environment to feed on the pests.
- Removing and discarding any part of the plant that is heavily infested.
- Regularly washing and cleaning your plants to remove any visible pests or eggs.
- Using insecticides or miticides to manage infestations.
