Barleria blepharoides Lindau grows well under full sunlight exposure. It can also tolerate partial shade to an extent. Maximum hours of sunlight exposure result in better growth and blooming of the plant.
Temperature Requirements
The temperature range suitable for the growth of Barleria blepharoides Lindau is between 10°C to 40°C. However, the ideal temperature range for its growth varies from 20°C to 30°C. This plant can survive mild frost, but it may adversely affect the blooming if exposed to such temperatures for a longer duration.
Soil Requirements
The ideal soil type for Barleria blepharoides Lindau is a well-drained loamy soil that is rich in organic matter. It prefers a slightly acidic soil with a pH range from 6.0 to 6.5. Sandy and clay soils can also support the growth of this plant, but they need to be amended with organic matter for better growth results. The soil should be moist but not waterlogged, as excessive moisture might lead to fungal diseases.
Cultivation Methods
The plant Barleria blepharoides Lindau, also known as eyelash barleria, can be grown indoors or outdoors, depending on the climate. It flourishes in well-draining soil and partial sunlight. It tends to grow up to 3 feet in height and spreads to a width of 2 feet with time. The plant makes a great addition to a garden or a container on a patio with partial shade and good drainage. It is important to keep the plant in a location with temperatures above 50°F.
Watering Needs
The plant requires a moderate amount of water for healthy growth. Water the soil when the top inch feels dry. Too much watering can cause the roots to rot and decay. Over-watering can also lead to the plant's death. If the plant is indoors, it needs to be watered once a week or whenever the topsoil becomes dry. In outdoor environments, the plant needs to be watered during the growing period and may require more frequent watering during dry spells.
Fertilization
The eyelash barleria requires a balanced fertilizer every four to six weeks during the growing season, which is between spring and fall. Over-fertilization can lead to leaf burn and damage to the plant. Proper balance of nitrogen, phosphorus, and potassium is essential for maximum growth and optimum flower production. Stop fertilizing the plant during the fall and winter seasons, when the plant is in dormancy.
Pruning
It is important to prune the plant in the late winter or early spring before new growth appears. This helps shape the plant and remove damaged or leggy growth. Pruning the plant after the blooming period encourages new growth and more blooms in the next season. Pinching off flowers as they fade can also encourage more blooms to form. Pruning can be done using pruning shears or scissors, making sure to cut the stem just above a leaf node.
Propagation of Barleria blepharoides Lindau
Barleria blepharoides Lindau can be propagated via different methods including seeds, cuttings, and division.
Propagation through seeds
The plant produces seeds in abundance, making propagation through seeds an easy and successful process. Obtain the seeds by collecting ripe seed pods from the plant. Sow the seeds during the spring in trays with seed compost that's kept moist throughout the germination period. After germination, transplant the seedlings into individual pots and keep them in a warm environment with good lighting until they are large enough to be planted outdoors.
Propagation through cuttings
The plant can also be propagated through cuttings. Select a healthy semi-hardwood stem from the plant and remove a section cutting that is 4 to 6 inches long. Make a small cut at the base of the cutting and dip it in rooting hormone powder to encourage faster rooting. Plant the dipped cuttings into a pot with potting soil that has been moistened. Keep the cutting in a warm and humid area with good lighting until it has rooted. Once it has grown several leaves, it can be transplanted outdoors.
Propagation through division
The plant can also be propagated through division. Divide the plant by taking a root clump, carefully separating it, and planting it in a new location. The new location should have well-draining soil where the plant can receive adequate sunlight.
Disease and Pest Management for Barleria blepharoides Lindau
Barleria blepharoides Lindau, commonly known as the African Bush Violet, is a perennial shrub that is native to Africa. Although it is a hardy plant, it is still susceptible to certain diseases and pests. Here are some common diseases and pests that might affect the plant and ways to manage them:
Diseases
Leaf Spot: This is one of the most common diseases that affect the African Bush Violet. The symptoms include circular or irregular brown spots on the leaves, which may get larger with time. To manage this disease, you can remove the infected leaves and disinfect the pruning tool to prevent further spread of the disease. Also, avoid overhead watering and ensure good air circulation around the plant to prevent high humidity levels.
Fungal Infections: Fungal infections such as powdery mildew and root rot can also affect the African Bush Violet. Powdery mildew can be identified by the white powdery substance that appears on the leaves while root rot can be detected by the soft, mushy roots. To manage fungal infections, you can use a fungicide or a baking soda solution to spray the infected areas. Also, ensure proper watering of the plant and avoid overwatering to prevent the onset of root rot.
Pests
Aphids: Aphids are small insects that suck the sap from the plant causing deformation and yellowing of the leaves. The best way to manage aphids is to physically remove them from the plant using a strong blast of water or by using insecticidal soap.
Scale insects: Scale insects are small, flat, oval-shaped insects that feed on the sap of the plant. They secrete a sticky substance called honeydew that attracts ants and promotes the growth of black sooty mold on the leaves. To manage scale insects, you can use horticultural oil or insecticidal soap to suffocate them.
Spider mites: Spider mites are tiny, spider-like insects that infest the undersides of leaves and feed on the plant sap. They cause yellowing and browning of the leaves and produce fine webbing on the plant. To manage spider mites, you can use a strong blast of water to dislodge them or use a miticide to kill them.
Overall, ensuring proper care and maintenance of the African Bush Violet is key to preventing the onset of diseases and pests. This includes regular pruning, proper watering, and adequate fertilization to keep the plant healthy and strong.
