In Ethiopia, it is called "Billa" in Amharic and "Nabru" in Tigrinya. Other common names include "Kongo-beh" in Sierra Leone and "Mope-biri" in Cameroon.
Light Requirements
Blepharis macra requires full sun exposure for optimal growth and development. The plant cannot thrive in shaded areas and may experience stunted growth or poor flower production in areas with insufficient sunlight.
Temperature Requirements
The plant thrives in warm temperatures, with a minimum temperature of 25°C and a maximum temperature of 35°C. Temperatures below 20°C may adversely affect the plant's growth rate and overall health, while temperatures above 40°C may cause leaf burn or wilting.
Soil Requirements
Blepharis macra requires well-draining soils rich in organic matter. The ideal soil pH should range from 6.0 to 7.5. The plant tolerates a wide range of soil types, including sandy, loamy, and clay soils. However, it cannot thrive in waterlogged or poorly drained soils, which may impede root growth and development.
Cultivation Methods
Blepharis macra (Nees) Vollesen, commonly known as 'Kikuyu Eye,' is a perennial herb that is native to Africa. It belongs to the Acanthaceae family. To cultivate this plant, you should start by selecting a site that receives plenty of sunlight. The soil should be well-draining and rich in nutrients. The best pH range for this plant is between 6.0 and 7.5.
To propagate this plant, collect ripe seeds and sow them in a tray. Cover the seeds with a thin layer of soil and water gently. After three to four weeks, the seeds will germinate, and you can transplant the seedlings to their permanent location. Ensure that the plants are spaced at least 12 inches apart.
Watering Needs
Blepharis macra requires regular watering, but it's essential not to overwater the plant. Water the plant deeply once a week, especially during the dry season. Ensure that the soil is moist but not waterlogged.
During the rainy season, you can reduce the frequency of watering. Overwatering can lead to root rot and other fungal diseases, which can cause the plant's death.
Fertilization
Blepharis macra requires regular fertilization to thrive. Apply a balanced fertilizer every month during the growing season. The fertilizer should be applied at the base of the plant and watered immediately.
The use of organic fertilizers is highly recommended as they help improve soil fertility and enhance the plant's growth. Avoid over-fertilizing the plant as it can lead to the accumulation of excess salts in the soil, which can harm the plant.
Pruning
Blepharis macra does not require regular pruning. However, you can prune the plant to shape it or remove any dead or damaged branches. Prune the plant during the dormant season to encourage vigorous growth in the next growing season.
When pruning, ensure that you use clean and sharp pruning shears to prevent the spread of diseases. It's also essential to dispose of any infected plant debris appropriately.
Propagation of Blepharis macra (Nees) Vollesen
Blepharis macra is a perennial plant known for its beautiful flowers and foliage. The plant is native to East Africa and is often grown as an ornamental plant in gardens and landscapes. Here are some of the propagation methods used for Blepharis macra:
Seed Propagation
The most common method of propagating Blepharis macra is through seeds. The seeds can be harvested from mature plants and sown in pots or directly in the ground. The seeds should be sown in well-draining soil and covered lightly with a thin layer of soil. The ideal time for sowing seeds is during the rainy season when the soil is moist and warm. The seeds will germinate within seven to fourteen days, and the seedlings can be transplanted when they are around six inches tall.
Cuttings Propagation
Blepharis macra can also be propagated through cuttings. Cuttings taken from healthy plants can be rooted in a well-draining soil mix and kept in a warm and humid environment until roots develop. The cuttings can then be transplanted to their permanent location.
Division Propagation
Another method of propagation for Blepharis macra is through division. The plant can be divided into smaller clumps, each with its own root system. This method is best done during the rainy season when the soil is moist. The divided clumps can be replanted in a well-draining soil mix, and regular watering should be done until the plants are established.
With the proper care and attention, propagating Blepharis macra is a straightforward process. Whether through seed, cuttings, or division, the plant can easily be multiplied, allowing for the creation of many beautiful and healthy plants.
Disease and Pest Management for Blepharis macra
Blepharis macra is a hardy, drought-tolerant plant that belongs to the Acanthaceae family. However, like any other plant, it is still vulnerable to pests and diseases. Here are some common issues that may affect this plant and how to prevent or manage them:
Diseases
Leaf spots: Leaf spots are common in Blepharis macra, caused by fungi such as Alternaria and Cercospora. Symptoms include irregular spots on the leaves that may be yellow or brown with a dark border. To manage this disease, remove infected leaves and dispose of them. Ensure that the plant is not overcrowded and has adequate airflow around it. Fungicides may also help to control the spread of the fungus.
Root rot: Root rot is caused by fungi such as Phytophthora, Rhizoctonia, and Fusarium. Symptoms of root rot include yellowing and wilting of the leaves, stunted growth, and root decay. To prevent this condition, ensure that the soil has proper drainage and avoid overwatering. To manage root rot, remove infected plants, treat the soil, and sanitize tools and pots.
Pests
Mealybugs: Mealybugs are small, soft-bodied insects that suck sap from the plant, causing yellowing and wilting of the leaves. They also produce a sticky residue that attracts ants and encourages mold growth. To manage mealybugs, remove them manually or using a brush and soapy water. You can also use insecticides or neem oil to control their population.
Spider mites: Spider mites are tiny pests that cause yellowing and bronzing of the leaves. They also produce webbing, making the plant unsightly. To manage spider mites, increase the humidity around the plant by spraying it with water regularly. You can also use insecticides or neem oil to control their population and remove any infested leaves.
In conclusion, the best way to manage diseases and pests in Blepharis macra is through prevention. Maintaining ideal environmental conditions such as proper watering and adequate airflow, and promptly removing any infected plants or leaves can go a long way in preventing the spread of pests and diseases.
