Light Condition
Angraecum bicaudatum Lindl. requires moderate to bright indirect sunlight for healthy growth. It cannot tolerate direct sunlight as it can cause the leaves to get scorched.
Temperature Requirements
The ideal temperature range for the growth of Angraecum bicaudatum Lindl. is between 60°F to 80°F (15°C to 27°C). This orchid prefers warm and humid conditions for optimal growth.
Soil Requirements
Angraecum bicaudatum Lindl. has an epiphytic growth habit and grows well in a bark-based soil mix that allows proper drainage and aeration. It is important to keep the soil moist but not wet as it can lead to root rot.
Cultivation
Angraecum bicaudatum Lindl. is an epiphytic orchid that grows in high-altitude regions. It prefers to grow in well-draining soil and needs a lot of light to thrive.
To cultivate Angraecum bicaudatum Lindl., plant it in a mixture of sphagnum moss, perlite, and pine bark. This will ensure that the soil is well-draining and provides enough nutrients to the plant to grow.
It is best to plant the orchid in a partially shaded location, as too much direct sunlight can damage the leaves. The ideal temperature for Angraecum bicaudatum Lindl. is between 20 - 25°C, and it requires high humidity to grow well.
Watering
Angraecum bicaudatum Lindl. needs frequent watering, but it should not be overwatered. Overwatering can lead to root rot and ultimately damage the plant. It is recommended to water the orchid when the soil feels dry to the touch.
Misting the plant once or twice during the day can help maintain high humidity levels, which is essential for the plant's health.
Fertilization
Fertilization of Angraecum bicaudatum Lindl. is essential for healthy growth. It is recommended to fertilize the plant during its active growing season, which is from spring to early summer.
Use a balanced fertilizer with equal amounts of nitrogen, phosphorus, and potassium (NPK), and ensure that the fertilizer is diluted before application. Overfertilization can cause damage to the roots and other parts of the plant.
Pruning
Pruning Angraecum bicaudatum Lindl. is not necessary, but it can help prevent the growth of any dead or diseased plant parts.
If you notice any dead or yellowing leaves, it is recommended to remove them using a sterile pair of scissors or pruners to prevent the spread of any disease.
Also, as the plant matures, it may become too large for the pot. In this case, it is recommended to repot the orchid in a larger container to give the roots more space to grow.
Propagation of Angraecum bicaudatum Lindl.
Angraecum bicaudatum Lindl., commonly known as the Double-tailed Angraecum, is a beautiful epiphytic orchid native to Madagascar. Growing this plant from seeds or vegetative propagation is possible, but it requires some skills and knowledge.
Propagation by seeds
Propagation by seeds is the most common method of Angraecum bicaudatum propagation. You can start by harvesting the seed pod from the flower spike once it has completely dried out. When attempting to extract the seeds, it is important to be careful and avoid damaging the seeds. You can soak the seeds in water for a day or two before sowing them in a well-draining mix. The ideal mix for Angraecum bicaudatum should include fine bark, perlite, and sphagnum moss. You can then cover the seeds with a thin layer of mix and place them in a warm and humid environment. You should expect the seedlings to germinate in a few weeks, depending on the temperature and humidity.
Vegetative propagation
Vegetative propagation of Angraecum bicaudatum is possible but not as common as seed propagation. The most common method of vegetative propagation is through division. You can carefully separate a clump of the plant into two or more sections and plant them in separate pots. It is essential to make sure that each section has enough roots and leaves to sustain itself. You can also propagate the plant through back-bulbs. Back-bulbs are older bulbs that are still alive but no longer produce flowers. You can separate the back-bulbs from the main plant and plant them in a well-draining mix. It may take several months or years for a back-bulb to produce new growth, but it is a very effective method for Angraecum bicaudatum.
Propagation of Angraecum bicaudatum requires patience and attention to detail. With the right approach, you can easily increase your collection of this beautiful orchid.
Disease and Pest Management for Angraecum bicaudatum Lindl.

Common Diseases
One of the most common diseases that affect Angraecum bicaudatum Lindl. is root rot. This is caused by overwatering and poor drainage, which can lead to fungal growth. The roots of the plant will appear brown and mushy, and the leaves may turn yellow or brown. To manage root rot, it is important to cut off the affected roots and replant the orchid in fresh soil with better drainage. Additionally, it is important to avoid overwatering the plant and to allow the soil to dry out between watering sessions.
Another disease that can affect Angraecum bicaudatum Lindl. is bacterial soft rot. This is caused by bacteria that can infect the plant through wounds or openings in the leaves or stems. Symptoms include water-soaked spots that turn soft and mushy. To manage bacterial soft rot, it is important to cut off the affected parts of the plant and treat it with a fungicide or bactericide. It is also important to ensure that the plant is not exposed to too much moisture, which can encourage the growth of bacteria.
Common Pests
Angraecum bicaudatum Lindl. is also susceptible to pest infestations, which can damage the leaves and stems of the plant.
