Light Requirements
Becium obovatum (E.Mey. ex Benth.) N.E.Br. var. knyanum (Vatke) Cufod thrives best in full sunlight conditions. The plant requires at least 6 hours of direct sunlight every day for proper growth and development. The lack of sufficient sunlight can result in stunted growth and reduced flowering.
Temperature Requirements
The plant prefers warm to hot temperatures ranging from 20°C to 35°C (68°F to 95°F). Becium obovatum (E.Mey. ex Benth.) N.E.Br. var. knyanum (Vatke) Cufod cannot survive frost or extremely cold temperatures. It is essential to ensure that the plant is not exposed to temperatures below 5°C (41°F) as this can result in severe damage or death.
Soil Requirements
Suitable soil conditions for Becium obovatum (E.Mey. ex Benth.) N.E.Br. var. knyanum (Vatke) Cufod are well-draining soils with a pH ranging from 5.5 to 7.5. The soil should be rich in organic matter and nutrients. Adding compost or manure to the soil before planting can help to improve the soil structure and nutrient content. Avoid waterlogged soils as they can lead to root rot and other fungal diseases.
Cultivation
Becium obovatum var. knyanum is an herbaceous plant that thrives in a sunny position and well-draining soil. It is native to East Africa and can be cultivated in other tropical regions where there is enough sunlight, warm temperatures, and low humidity.
Watering needs
The plant requires constant moisture in its root zone, but it is essential to prevent waterlogging, which can cause rotting of the roots. Watering should be done regularly, especially during periods of low rainfall, but ensure the soil is dry before the next watering. Always water at the base of the plant to avoid wetting the leaves, which can cause fungal diseases.
Fertilization
To encourage healthy growth and flowering of Becium obovatum var. knyanum, it is essential to apply a balanced fertilizer rich in nitrogen, phosphorus, and potassium. Fertilizer application should be done in early spring before the growing season. An organic compost mix or a slow-release fertilizer can also be used to feed the plant.
Pruning
Pruning is a necessary practice that helps to maintain the health and shape of the plant. It is advisable to prune Becium obovatum var. knyanum after the blooming period to control its height and keep it compact. Cut off dead or damaged leaves and branches to allow proper air circulation around the plant. Regular pruning also encourages bushier growth and more flowering.
Propagating Becium obovatum var. knyanum
Becium obovatum var. knyanum, also known as Kikuyu Toilet Plant, is a perennial plant species found in East Africa. It is a small shrub that can reach up to 0.5 meters in height. The plant is commonly grown for its aromatic leaves and beautiful flowers. Propagation of Becium obovatum var. knyanum can be done using various methods.
Propagation from Seeds
Propagation from seeds is the most common method used to propagate Becium obovatum var. knyanum. The best time to sow the seeds is at the beginning of the rainy season. Sow the seeds in well-draining soil in a sunny location. The seeds can be sprinkled on the soil surface and covered with a thin layer of soil. Keep the soil moist, but not waterlogged. The seeds usually germinate within two weeks.
Propagation from Cuttings
Becium obovatum var. knyanum can also be propagated from cuttings. Collect cuttings of about 5-10 cm in length from the parent plant. Make sure the cuttings are taken from healthy branches. Remove the lower leaves from the cuttings, leave a few on the tip. Dip the cuttings in a rooting hormone and plant them in a well-draining rooting medium. Keep the soil moist and place the container in a warm and shady location. The cutting should root in 3-4 weeks.
Propagation from Division
Propagation from division is another method used to propagate Becium obovatum var. knyanum. Carefully dig up the parent plant and divide the root mass into several smaller sections. Each section should have at least one stem. Plant each section in a well-draining soil mixture and water them generously. Divide the plant during the rainy season for best results.
Disease Management
Becium obovatum var. knyanum is susceptible to various diseases which can cause irreparable damage to the plant if not managed appropriately. Some common diseases that can affect this plant are:
- Leaf spot disease: This disease often manifests in the form of yellow or brown spots on the plant's leaves. The spots can spread and cause defoliation, reducing the plant's ability to produce food. To manage this disease, affected leaves should be removed immediately, and fungicides can be applied to prevent the spread of the disease.
- Root rot: Overwatering can cause root rot, which can ultimately kill the plant. Plants with root rot show wilting, yellowing, and stunted growth. To manage root rot, reduce watering frequency and improve soil drainage.
- Powdery mildew: Powdery mildew appears as a white, powdery substance on the plant's leaves. It spreads quickly, leading to a decline in plant health. To manage powdery mildew, affected leaves should be discarded, and fungicides can be applied.
Pest Management
Becium obovatum var. knyanum is also susceptible to pest infestations, which can cause damage to the plant leaves, stems, and roots. Here are some common pests that might attack this plant and how to manage them:
- Aphids: These pests typically appear in colonies on the underside of the plant leaves and suck sap from the plant. To manage aphids, they can be sprayed with a strong jet of water, and insecticides can be applied.
- Caterpillars: Caterpillars chew on the leaves and stems of the plant, causing damage. To manage caterpillars, handpicking off the caterpillars can be a non-toxic method, or insecticides can be applied.
- Spider mites: Spider mites are small pests that feed on the plant sap, causing the leaves to develop a yellow or bronze color. To manage spider mites, they can be sprayed with water or treated with insecticidal soap.
