The leaves are thin and elongated, measuring about 5-7 cm in length and 0.6-1.5 cm in width. The surface of the leaves boasts a glossy green color, with visible venation that gives them a distinctly veined appearance.
The inflorescence of the Arachnocalyx viscidus is held on a short peduncle, which arises from the base of the plant. The flowers form a dense raceme, and each individual flower is around 1.5 cm across. The petals are oval and rounded at the tip, while the sepals are lanceolate. The color of the flowers ranges from yellow to green, and they are covered in sticky secretions that attract insects such as flies.
Uses
Although the Arachnocalyx viscidus has no known medicinal properties, it is a popular plant in the horticulture industry due to its unique appearance. The plant is commonly grown as an ornamental plant in gardens and as a houseplant. Its striking appearance makes it an attractive display when placed in a terrarium or hung as a basket plant.
In conclusion, Arachnocalyx viscidus is a rare plant species that is native to West Africa. Its unique appearance sets it apart from other orchids, making it a favorite among gardeners and horticulturists.
Light Requirements
Arachnocalyx viscidus requires bright, indirect light to grow properly. It is advisable to keep it away from direct sunlight as it may lead to leaf scorching.
Temperature Requirements
The plant thrives well in warm temperatures ranging between 20-30°C during the day and slightly cooler temperatures of around 16-20°C at night. It's essential to keep the temperature consistent to prevent stress and shock in the plant.
Soil Requirements
Arachnocalyx viscidus prefers moist, well-draining soils rich in organic matter. The soil should have a pH range of 5.5-6.5, which is slightly acidic. It's essential to ensure that the soil doesn't become waterlogged as this may lead to root rot.
Cultivation Methods
Arachnocalyx viscidus (N.E.Br.) E.G.H.Oliv. is a rare orchid plant, so it must be grown indoors or in a controlled environment. The perfect temperature range for growing this plant is between 60 to 90 °F. Humidity level should be maintained around 60% to 70%. The best potting medium for Arachnocalyx viscidus is a mix of sphagnum moss, perlite, and charcoal. Ensure that the potting mix is well-draining, and the pot size is just right for the plant's root system.
Watering Needs
It is crucial to water Arachnocalyx viscidus orchid plant adequately. Watering should be done once every week during the growing season and once every two weeks during the dormant season. Avoid overwatering the plant, as it can lead to root rot. Additionally, use rainwater or distilled water instead of tap water as the plant may be sensitive to the minerals found in tap water.
Fertilization
Arachnocalyx viscidus orchid plant requires regular fertilization to help it bloom and grow. Begin feeding with a balanced orchid fertilizer, with an N-P-K ratio of 20-20-20 during the growing season. Fertilization should be done once every two weeks. In the dormant season, reduce the amount of fertilizer to once per month.
Pruning
Pruning helps to keep Arachnocalyx viscidus plant looking well-groomed. Prune the flower spikes carefully after the flowers finish blooming. Before pruning, ensure that you have a sterilized pair of scissors or pruning shears. The spikes should be cut above a node, which is a small raised bump. This will encourage new flower spikes to grow. Remove any yellow, damaged, or diseased leaves to encourage healthy growth.
Propagation methods for Arachnocalyx Viscidus
Arachnocalyx viscidus is a plant species that belongs to the orchid family and is native to Eastern Africa. The plant is known for its attractive flowers and is often cultivated for ornamental purposes.
Propagation through division
One of the most common methods of propagating Arachnocalyx viscidus is through division. This can be done when the plant has outgrown its pot, and the rhizomes have produced new growth points. The process involves removing the plant from the pot, separating the rhizomes with a sterilized knife, and replanting them in separate pots with fresh potting mix.
Propagation through stem cutting
Another method of propagating Arachnocalyx viscidus is through stem cutting. This process involves selecting healthy stems and cutting them into sections that contain at least one node. The stem cuttings can then be dipped in rooting hormone powder and planted in pots with moist potting mix. To increase the chance of success, keep the cuttings in a warm and humid environment.
Propagation through tissue culture
Tissue culture is a propagation method that is used for many orchid species, including Arachnocalyx viscidus. The process involves taking a small tissue sample from a healthy plant and placing it in nutrient-rich agar. The tissue sample will then develop new shoots, which can be removed and planted in pots with fresh potting mix.
Propagation through seed germination
Seed germination is a less common method of propagating Arachnocalyx viscidus. If you choose to propagate through seed germination, you will need to obtain fresh seeds from a reliable source. The seeds should be sown in sterile potting mix, kept moist, and kept in a warm and humid environment. The seedlings will need to be monitored closely and only repotted once they have developed enough size and strength to handle it.
Disease and Pest Management for Arachnocalyx viscidus:
Arachnocalyx viscidus is a sturdy tropical plant that is relatively resistant to disease and pests. However, it can still be affected by a few common issues that may impact its growth and cause damage. Here are some helpful tips on disease and pest management for Arachnocalyx viscidus:
Pests:
Aphids: Aphids are common pests that can be found on the leaves and stem of Arachnocalyx viscidus. They suck the sap from the plant and cause distortion or discoloration of foliage. It can be controlled using insecticidal soap or neem oil. Regularly spray the plant with any of the mentioned solution to keep aphids at bay.
Spider mites: Spider mites are tiny pests that are hard to spot with the naked eye. They can cause yellowing or bronzing of foliage, particularly in dry conditions. Consistent watering and overhead sprays of water can help keep spider mites under control. Apply soapy water or neem oil to the plants to deter and control spider mites.
Diseases:
Leaf Spots: Leaf spots typically appear on older leaves. It can be caused by poor air circulation, overwatering and leaf dampness. To manage leaf spot, remove infected leaves and discard them in the trash, avoid overhead watering, and try watering the plant at its base, while keeping the foliage dry.
Fungal and Bacterial Disease: Arachnocalyx viscidus might suffer from fungal and bacterial diseases like Rhizoctonia root rot, Alternaria leaf spot, or bacterial soft rot. As a preventive measure, keep the plant healthy, remove any infected parts immediately, and avoid overhead watering. If the plants still become infected, treat it with an organic fungicide or bacterial spray.
By following these pest and disease management tips, you can help protect and preserve the health of your Arachnocalyx viscidus plant.
