Blepharispermum spinulosum Oliv. & Hiern is a beautiful evergreen shrub that belongs to the family of Astareaceae. It has its origin in the tropical and subtropical regions of Africa and requires specific environmental conditions for optimal growth and development.
Light Requirements
Blepharispermum spinulosum thrives in areas with full sunlight exposure or partial shade. However, it is essential to avoid exposing the plant to excessive heat and direct sunlight during the hotter and drier months. In areas with extremely high temperatures, partial shading is necessary to protect the plant from dehydration and sunscald.
Temperature Requirements
The ideal temperature range for Blepharispermum spinulosum is between 18°C to 27°C. The plant can tolerate temperatures below 10°C but may experience stunted growth, especially if exposed for long. It cannot survive in areas with freezing temperatures below 0°C, and therefore, it is not suitable for cold regions.
Soil Requirements
Blepharispermum spinulosum thrives in well-drained soils that provide a stable root zone with mild levels of moisture. The soil should have a pH range of between 6 to 7.5, and it should be amended with organic compost that increases nutrient availability and soil structure. The plant prefers sandy loam and clay soils that absorb water and resist compaction, and it is sensitive to waterlogged soils that may cause rotting on the roots.
Cultivation of Blepharispermum spinulosum Oliv. & Hiern
Blepharispermum spinulosum Oliv. & Hiern is a plant that can be cultivated in pots or in the garden. It requires well-draining soil and adequate sunlight. The plant is suitable for cultivation in USDA Hardiness Zones 10-11, but it can also be grown in other regions if given proper care.
The plant is propagated by seeds which can be sown directly in the soil or in containers filled with a potting mix. The seeds should be sown at a depth of about 2 cm and spaced at a distance of about 10 cm. The soil should be kept moist until the seeds germinate, which usually takes about 1-2 weeks.
Watering Needs of Blepharispermum spinulosum Oliv. & Hiern
Blepharispermum spinulosum Oliv. & Hiern requires regular watering to thrive. The soil should be kept moist, but not waterlogged. It is important to avoid overwatering as this can lead to root rot.
The frequency of watering will depend on various factors including the temperature, humidity, and soil type. Generally, the plant should be watered about once or twice a week, but this may vary depending on the above factors.
Fertilization of Blepharispermum spinulosum Oliv. & Hiern
Blepharispermum spinulosum Oliv. & Hiern can benefit from regular fertilization. A balanced fertilizer with equal amounts of nitrogen, phosphorus, and potassium can be applied every two to three months during its growing season, which is generally spring to fall.
The amount of fertilizer applied should be as per the instructions on the package, and it should be applied to the soil, not to the leaves or stems of the plant.
Pruning of Blepharispermum spinulosum Oliv. & Hiern
Pruning of Blepharispermum spinulosum Oliv. & Hiern is not necessary, but it can be done to promote bushier growth and to remove dead or damaged leaves or stems. The pruning should be done in the spring before new growth starts.
To prune the plant, use clean and sharp pruning shears to make clean cuts. Cut stems at a 45-degree angle, just above a node or bud. The plant may be pruned back to about ? to ½ of its original size to promote bushier growth.
Propagation of Blepharispermum spinulosum Oliv. & Hiern
Blepharispermum spinulosum Oliv. & Hiern is a species endemic to southern Africa and is commonly known as the thorn apple. Propagation of this species can be achieved through the use of seeds and cuttings.
Seed propagation
Seeds of Blepharispermum spinulosum should be collected from mature fruits. The collected seeds should be air-dried before storage or sowing. Germination of the seeds is enhanced by the removal of the seed coat. This can be achieved through scarification (abrasion) of the seeds' outer layer. After scarification, seeds should be soaked in water for 24-48 hours before sowing in a well-drained soil mix. Seeds should be sown at a depth of about three times their size and lightly covered with soil. The soil should be kept moist, but not waterlogged, until the seedlings emerge.
Cutting propagation
Blepharispermum spinulosum can also be propagated through the use of cuttings. Stem cuttings should be taken from current year growth and should be about 10-15 cm long. All the leaves on the lower two-thirds of the cutting should be removed, and the cutting should be dipped in a rooting hormone powder. Cuttings should be planted in a well-draining soil mix and covered with a plastic bag to maintain humidity levels. After about six weeks, cuttings should have rooted and can be transplanted into individual containers or planted directly in the ground.
Disease and Pest Management for Blepharispermum spinulosum Oliv. & Hiern
Blepharispermum spinulosum Oliv. & Hiern is a plant that is known to be relatively resistant to pests and diseases. However, it is not immune to them, so it is essential to understand the common diseases and pests that might affect the plant and how to manage them.
Common Diseases
One of the most common diseases that can affect Blepharispermum spinulosum Oliv. & Hiern is powdery mildew. This fungus presents as a white powdery substance on the leaves of the plant. To manage this disease, it is recommended to keep the plant's environment dry and remove any infected leaves immediately. In severe cases, a fungicide may be necessary.
Another disease that can affect Blepharispermum spinulosum is rust. Rust appears as yellow or orange spots on the leaves of the plant. Like with powdery mildew, it is essential to remove infected leaves and keep the plant's environment dry. A fungicide specific to rust may also be necessary.
Common Pests
One of the most common pests that can affect Blepharispermum spinulosum Oliv. & Hiern is spider mites. These tiny pests suck the sap from the plant and can cause yellowing and wilting of the leaves. To manage spider mites, it is recommended to spray the plant with a strong stream of water to knock them off or use a miticide. It is also essential to keep the plant's environment humid to discourage spider mites.
Aphids are another pest that can affect Blepharispermum spinulosum. These small, soft-bodied insects also suck the sap from the plant and can cause curling of the leaves. To manage aphids, it is recommended to spray the plant with a strong stream of water or use an insecticidal soap.
Tips for Pest and Disease Management
Prevention is always better than treatment when it comes to pest and disease management. Keeping the plant's environment clean and dry, removing any dead or infected plant material, and promoting healthy growth through proper watering and fertilization can go a long way in preventing pests and diseases.
Regularly inspecting the plant for any signs of pests and diseases and catching them early can also help manage the issue before it gets out of hand. In severe cases, it may be necessary to use chemical treatments, such as fungicides and insecticides, but these should be used judiciously and only as a last resort.
