Adenodolichos bequaertii De Wild. var. purpureus De Wild. is currently classified as an endangered species due to habitat loss and overexploitation. The plant is threatened by deforestation, agriculture expansion, and grazing. The loss of habitat has resulted in the decline of this species, and it is now protected under the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). Efforts are being made to conserve the plant and its habitat, and the local communities are actively involved in these conservation efforts.Light Requirements
Adenodolichos bequaertii De Wild. var. purpureus De Wild. thrives in full sun to partial shade. However, it blooms best when grown in full sun. If planted in a shaded area, it is likely to produce weaker stems and fewer flowers.
Temperature Requirements
The plant grows best in areas with warm temperatures ranging from 21°C to 29°C (70°F to 85°F). However, it can be grown in regions with temperatures as low as 16°C (60°F) and as high as 35°C (95°F), although growth may be slowed in extreme temperatures. The plant is not frost-tolerant and needs to be protected from extreme cold and frost.
Soil Requirements
Adenodolichos bequaertii De Wild. var. purpureus De Wild. grows best in well-draining soil with a pH of 6.0 to 7.0. The soil should be rich in organic matter to allow good drainage and aeration. The plant can tolerate a wide range of soil types, from sandy to clay soils, as long as there is good drainage.
Cultivation of Adenodolichos bequaertii De Wild. var. purpureus De Wild.
Adenodolichos bequaertii De Wild. var. purpureus De Wild. thrives in tropical and sub-tropical climates. It can be grown in well-draining soil with organic matter content.
You can grow the plant in full sun or partial shade. However, it prefers a well-lit area that receives sunlight for at least four hours a day.
Watering Needs
Proper watering is crucial to the plant's growth. While it is somewhat drought-tolerant, Adenodolichos bequaertii De Wild. var. purpureus De Wild. prefers moist soil at all times. As a result, it is crucial to keep the soil moist but not waterlogged.
During the rainy season, the plant receives enough water. However, during the dry season, you may have to supplement the plant's water needs by regular watering.
Fertilization
Fertilizers provide necessary nutrients to the plant, ensuring growth and development. Adenodolichos bequaertii De Wild. var. purpureus De Wild. requires fertilizer applied twice a year. The fertilizer should be well-balanced with nitrogen, phosphorus and potassium.
You can also use a foliar spray fertilizer on the plant's leaves, which helps foliage growth.
Pruning
Pruning helps maintain the plant's shape and promote growth. It should be done between the growing season to encourage new growth.
Cut back any dead or wilted stem or foliage as well as any overgrowth that affects the plant's shape.
Propagation of Adenodolichos bequaertii De Wild. var. purpureus De Wild.
There are different methods to propagate Adenodolichos bequaertii De Wild. var. purpureus De Wild., including:
Seeds
The plant can be propagated through its seeds. It is important to note that the seeds must be fresh, mature, and viable to ensure successful propagation. Seeds must be sown in seed trays filled with well-draining soil mix and kept moist. The ideal temperature range for seed germination is between 20°C and 30°C. Seeds will germinate within two to three weeks, and seedlings can be transplanted into individual containers once they reach a height of 5-7 cm.
Cuttings
Another method to propagate Adenodolichos bequaertii De Wild. var. purpureus De Wild. is through cuttings. Select stem cuttings from the plant, making sure they are healthy and mature. The cuttings should be around 10-15 cm long, and cut below a node. Dip the cuttings in rooting hormone and plant them in a well-draining soil mix. Keep the soil moist, and place the cuttings under indirect light. Roots will develop within three to four weeks, and the plants can be transplanted into individual containers.
Division
Adenodolichos bequaertii De Wild. var. purpureus De Wild. can also be propagated through division. The best time to divide the plant is during the growing season when it is actively producing new growth. Carefully dig out the plant and gently separate the clumps into smaller sections, ensuring that each section has enough roots and shoots. Plant each division in a well-draining soil mix and water thoroughly. Place the newly propagated plants under indirect light until they are established.
Disease Management
Adenodolichos bequaertii De Wild. var. purpureus De Wild. is generally a robust plant, but it can be vulnerable to certain diseases. The most common diseases affecting this plant include:
- Fungal diseases: These can manifest in the form of leaf spots, powdery mildew, and root rot. To manage fungal diseases, it's important to maintain good cultural practices such as proper spacing, watering, and fertilization. Additionally, fungicides may be used preventatively or to control an outbreak. It's important to select a fungicide that is appropriate for the type of fungal disease affecting the plant.
- Bacterial diseases: Bacterial diseases can cause leaf spots, stem cankers, and wilting. To manage bacterial diseases, it's important to remove and dispose of infected plant material to prevent the disease from spreading. Additionally, copper-based fungicides may be helpful in controlling the spread of bacterial diseases.
Pest Management
Adenodolichos bequaertii De Wild. var. purpureus De Wild. can also be vulnerable to a variety of pests. Some common pests that may affect this plant include:
- Aphids: These tiny insects can suck the sap out of leaves and cause distortion and yellowing of foliage. To manage aphids, soap and water sprays may be effective, or beneficial insects such as ladybugs or lacewings may be introduced to the garden to control the population.
- Caterpillars: Caterpillars can cause defoliation and damage to the plant. Bt (Bacillus thuringiensis) sprays may be effective in controlling caterpillar populations, but it's important to properly identify the type of caterpillar present before applying any treatment.
- Spider mites: These pests can cause yellowing and stippling of foliage. To manage spider mites, regular misting of the foliage with water may help prevent infestations. If an infestation does occur, insecticidal soap sprays may be effective in controlling the population.
Overall, the best way to manage pests and diseases for Adenodolichos bequaertii De Wild. var. purpureus De Wild. is to maintain good cultural practices, regularly inspect the plant for signs of infestation or disease, and to quickly address any issues that arise.
