Light Requirements
Becium knyanum typically requires full to partial sunlight for successful growth. This plant can tolerate some shade, but it requires a minimum of at least four hours of direct sunlight per day.
Temperature Range
The ideal temperature range for the successful growth of Becium knyanum is between 18°C and 28°C. This plant can tolerate some temperature fluctuations, but extreme temperatures (above 35°C or below 5°C) can have adverse effects on its growth and development.
Soil Requirements
Becium knyanum requires well-draining, nutrient-rich soil for successful growth. The plant can be grown in a variety of soil types, including sandy loam, clay loam, and lateritic soils, as long as they are well-draining. A soil pH of 6.0 to 7.5 is preferred for optimal growth.
Adequate moisture is also critical for this plant's growth, and soil moisture levels should be maintained at a moderate level. Overwatering can cause root rot, so it is important to avoid waterlogging.
Additionally, organic matter can be used to improve soil quality and nutrient availability for the plant. Applying compost or a slow-release fertilizer once or twice a year can provide additional nutrients that become deficient over time.
Cultivation Methods for Becium knyanum (Vatke) N.E.Br. ex Broun & R.E.Massey
Becium knyanum is a plant that thrives in warm, sunny environments found in its native habitat. To cultivate this plant, it is important to mimic the natural conditions of its native habitat.
Firstly, make sure you plant the Becium knyanum in well-draining soil that is rich in organic matter. The soil should have a pH of around 6 – 7.5.
Seeds can be sown in trays or directly in the ground during the warm season. Provide the plant with ample sunlight, as this promotes growth and ensures healthy leaves.
It is best to avoid planting Becium Knaynum in cold weather as it prefers warm environments.
Watering Needs for Becium knyanum (Vatke) N.E.Br. ex Broun & R.E.Massey
Becium knyanum requires adequate watering to thrive, especially during the dry seasons. Ensure that the soil is moist but not waterlogged. Proper drainage is important to ensure the plant's survival.
Water Becium knyanum in the early morning or late evening when the sun is not high in the sky. This prevents the water from evaporating before reaching the roots.
Monitor the plant regularly and adjust the amount of water given based on the moisture level of the soil. A wilted appearance of leaves is an indication of under-watering, while the destruction of the stem indicates overwatering.
Fertilization for Becium knyanum (Vatke) N.E.Br. ex Broun & R.E.Massey
Becium knyanum benefits greatly from regular fertilization. Use organic fertilizers that are rich in nitrogen, phosphorus, and potassium, such as manure or compost.
Apply fertilizers at least twice a year, once at the beginning of the growing season and the second at the peak of the growing season. Avoid over-fertilizing as it may cause burning or damage to the plant.
Pruning for Becium knyanum (Vatke) N.E.Br. ex Broun & R.E.Massey
Pruning helps prevent the plant from becoming too leggy and encourages bushier growth of the plant. It is best to do the pruning in the early spring when the plant is just beginning its growing season.
Remove dead leaves, branches and flowers to ensure the plant uses its resources effectively. Pinch the tips of the branches, which promotes branching and encourages the plant's bushy growth.
It is important to utilize sharp pruning shears and clean them with alcohol to prevent the spread of plant diseases, such as bacterial wilt.
Propagation of Becium knyanum
Becium knyanum, commonly known as the "Kenyan Sage," is a perennial plant that can be propagated through several methods:
Seed propagation
Seeds of Becium knyanum are small and can be directly sown into the soil. It is recommended to soak the seeds in warm water for 24 hours before planting to promote germination. The best time to sow seeds is during the start of the rainy season to ensure adequate moisture for germination. The seedlings should be transplanted after 6-8 weeks when they reach a height of 10 cm.
Cuttings
Softwood cuttings of Becium knyanum can be taken in the spring or early summer. Cuttings should be approximately 8-10 cm long and taken from the terminal shoots. Remove the lower leaves and dip the cut end in rooting hormone before planting them in a well-draining rooting medium. The cuttings should be kept moist and require high humidity. Rooting should occur within 6-8 weeks.
Division
Becium knyanum can be propagated through division when the plant has become large enough. Dig up the plant and divide the roots into several sections. Replant each section in a prepared bed, ensuring they are well watered and mulched to reduce moisture loss. The best time to divide the plant is in the early spring.
Disease Management
Becium kyanum (Vatke) N.E.Br. ex Broun & R.E.Massey is prone to different diseases such as fungal, bacterial, and viral diseases. To manage these diseases, it is important to maintain proper plant hygiene. Remove all plant debris from around the plant and ensure that the plant is well ventilated. This will help reduce the spread of spores and provide an environment that is less conducive to the growth of pathogens.
Fungal diseases like powdery mildew and leaf spots can be managed by applying a copper-based fungicide. A broad-spectrum fungicide with active ingredients like mancozeb or chlorothalonil can be used to control different fungal diseases. Bacterial infections like leaf blight and bacterial wilt can be managed by cutting off the affected parts of the plant, removing them, and sterilizing pruning tools.
Viral diseases like mosaic and leaf curl cannot be cured. Infected plants should be removed and destroyed, and preventive measures should be taken to avoid further spread. It is also important to avoid cross-contamination of plants between different areas.
Pest Management
The most common pests that can affect Becium kyanum (Vatke) N.E.Br. ex Broun & R.E.Massey are aphids, spider mites, and whiteflies. These pests can be managed by regular monitoring and early detection. A strong water spray can be used to remove low infestations of aphids and spider mites.
Neem oil or insecticidal soap can be used to manage severe infestations. Pyrethroid insecticides can also be used, but they can harm beneficial insects and pollinators. It is important to apply insecticides early in the morning or late in the evening when bees are less active.
Preventive measures like crop rotation, removing weeds, and intercropping with plants that have natural repellent properties can help reduce pest populations. The use of sticky traps and pheromone lures can also be useful in monitoring and mass trapping of pests.
