The leaves are simple, opposite, elliptic in shape and can reach 10 cm in length and 4 cm in breadth. The leaves have an acute apex and a cordate base, with a slightly serrated margin. The flowers are pink, attractive and are arranged in inflorescence, which grows up to 1 cm in diameter. The fruit is a capsule that holds numerous seeds, highly ornamented with hairs and a long beak.
Uses of Lasiodiscus zenkeri Suess.
Lasiodiscus zenkeri Suess. has a wide range of uses in traditional medicine. The leaves and bark are boiled to extract a decoction, which is used to treat various kinds of illnesses such as bronchitis, malaria, arthritis, headaches, and high blood pressure. The plant's roots and stem contain astringent properties, which can be used to stop bleeding and treat wounds. In Nigeria, Christophoriana is used to make a local beer called "Burukutu," which is highly prized by locals and used during cultural festivities.
Light Requirements:
Lasiodiscus zenkeri Suess. thrives in bright, indirect light conditions. They prefer to be placed near a window with filtered light or under fluorescent lights, which mimic natural light conditions. Direct sunlight is harmful to the plant as it can burn the foliage. Therefore, it is best to avoid placing the plant in direct sunlight.
Temperature Requirements:
Lasiodiscus zenkeri Suess. prefers a warm environment with temperatures ranging from 18°C to 26°C (64°F to 78°F). It cannot tolerate extreme temperatures and should be kept away from drafts or air conditioning vents. When the temperature drops below 13°C (55°F), the plant might start to wilt, which can be prevented by moving it to a warmer location.
Soil Requirements:
Lasiodiscus zenkeri Suess. requires well-draining soil with good aeration. The soil should have a pH level between 6.0 and 7.5 and should be rich in organic matter. A mix of peat moss, perlite, and sand is ideal for this plant. Make sure the soil is moist, but not waterlogged, as waterlogging can cause root rot. Fertilize the plant during the growing season, i.e., spring and summer, with a balanced fertilizer to ensure optimal growth.
Cultivation methods
The Lasiodiscus zenkeri Suess. plant is a slow-growing but hardy species that can adapt to different environments. The plant thrives in well-drained soil that is rich in organic matter and slightly acidic. It prefers bright, filtered sunlight or partial shade to full shade conditions.
Propagation can be done through seeds, but it is recommended to propagate through stem cuttings to keep the characteristics of the parent plant intact. The cuttings should be taken during the spring season and rooted in moist soil under warm temperature conditions.
Watering needs
The Lasiodiscus zenkeri Suess. plant requires regular watering to keep the soil moist but not waterlogged. The frequency of watering will depend on the environmental conditions, soil type, and pot size. During the growing season, the plant will require more water than during the dormant season. To avoid overwatering, allow the soil to dry out slightly before watering again.
Fertilization
The Lasiodiscus zenkeri Suess. plant is not a heavy feeder, but it will benefit from occasional fertilization. Fertilize the plant during the growing season every 2-3 weeks using a balanced, liquid fertilizer diluted to half strength. Avoid fertilizing during the dormancy season as this can cause damage to the plant.
Pruning
The Lasiodiscus zenkeri Suess. plant does not require extensive pruning, but regular maintenance is necessary to keep the plant healthy and attractive. Prune any dead or damaged leaves or stems as soon as they appear. You can also prune to control the size and shape of the plant. Pruning should be done during the growing season when the plant is actively growing. Use sharp, sterile pruning tools to prevent the spread of diseases.
Propagation of Lasiodiscus zenkeri Suess.
Lasiodiscus zenkeri Suess. is a popular plant among gardeners and plant enthusiasts due to its showy flowers and easy maintenance. Propagation of this plant can be done through several methods.
Seeds
Propagation of Lasiodiscus zenkeri Suess. through seeds is one of the easiest and most popular methods. The seeds can be collected from the plant after the flowers have faded and the seed pods have matured. These seeds can be sown directly into a well-draining soil mix in a pot or seed tray. Keep the soil moist and in a warm, bright location for optimal germination.
Cuttings
Another popular method of propagating Lasiodiscus zenkeri Suess. is through stem cuttings. Using a sharp and sterilized pair of scissors, take a 4-6 inch long cutting from the plant's stem just below a leaf node. Remove the leaves from the bottom half of the cutting and dip the stem into rooting hormone. Place the cutting into a well-draining soil mix in a pot and keep it in a warm, bright location. Keep the soil moist and the cutting should root in a few weeks.
Division
Lasiocdiscus zenkeri Suess. can also be propagated through division. Gently remove the plant from its pot and separate the root ball into several smaller sections. Make sure each section has a healthy amount of roots and stems. Plant these sections into pots containing a well-draining soil mix. Keep the soil moist and the plant in a warm, bright location until it establishes roots.
Air Layering
Propagation of Lasiodiscus zenkeri Suess. through air layering can also be done. This method involves encouraging the plant to produce roots along a stem while it is still attached to the parent plant. To do this, select a healthy stem and remove a section of its bark. Apply a rooting hormone to the exposed area, and wrap it in moist sphagnum moss and plastic wrap. Once roots have formed, remove the rooted section from the parent plant and plant it into a pot with a well-draining soil mix. Keep the soil moist and the plant in a warm, bright location.
Disease Management
Lasiocdiscus zenkeri Suess. can be affected by various fungal and bacterial diseases. The most common disease of the plant is stem canker caused by Botryodiplodia theobromae. It results in wilting and eventual death of the plant. The best method of managing this disease is pruning and destroying the affected parts of the plant and promoting good hygiene practices.
Leaf spot disease caused by the fungus Cercospora sp. is another common disease that affects the plant. It can lead to defoliation of the plant and ultimately, stunted growth. The best strategy to manage this disease is to remove and destroy affected leaves and treat the plant with fungicides such as copper-based fungicides.
Root rot caused by the fungus Pythium sp. can cause yellowing and wilting of the leaves as well as the eventual death of the plant. To manage this disease, plants should be watered adequately and the plant's roots should not be too wet. Removing infected plants and soil can also help reduce the spread of Pythium sp.
Pest Management
Lasiodiscus zenkeri Suess. can be attacked by various pests such as mealybugs, spider mites, and aphids. These pests can cause significant damage to the plant. One of the best strategies in pest management is to detect them early before they cause extensive damage.
Mealybugs are the most common pest infesting Lasiocdiscus zenkeri Suess. They suck sap from the plant's leaves, which causes the leaves to yellow and fall off. To manage mealybugs, regular inspections should be done on the plant. If Mealybugs are detected, a solution of water, soap and alcohol can be sprayed on them to kill and remove them.
Spider mites are also common pests that can cause significant damage to the plant. Symptoms of spider mites include yellowing of leaves as well as brown, necrotic spots on the leaves. To manage spider mites, the use of miticides can be employed to control and reduce infestation. Neem oil is also another alternative for managing spider mites.
Aphids feed on the soft growth of the plant, causing distortion and stunted growth. Aphids excrete a sticky substance that attracts other pests such as ants and sooty mold. Solutions of soapy water, alcohol, or neem oil can be used to deter and manage aphids.
