Light: Barleria longistyla Lindau thrives well in full sun to partial shade. It requires at least six hours of direct sunlight to grow optimally. If the plant is grown in low light areas, it will develop tall, spindly growth and produce fewer flowers.
Temperature: This plant prefers warm and humid conditions with temperatures ranging from 20-30°C. It is sensitive to frost and cannot tolerate temperatures below 10°C, which can kill the plant. Therefore, it is best to grow Barleria longistyla Lindau in tropical and subtropical regions.
Soil: Barleria longistyla Lindau grows well in well-drained soil that is rich in organic matter. It prefers slightly acidic to neutral soils, with a pH range between 6 to 7.5. To enhance the drainage capacity of the soil, it is recommended to add river sand, perlite, or other coarse materials to the planting soil and to maintain soil moisture.
Fertilizers: A well-balanced fertilizer with equal amounts of nitrogen, phosphorus, and potassium is recommended to promote flowering and healthy growth of the plant. Fertilization should be done every four to six weeks during the growing season but should be stopped during the winter months.
Watering: Barleria longistyla Lindau requires regular watering to maintain soil moisture. The frequency of watering depends on the climatic conditions; it must be watered weekly during the dry season and twice a week during the hot summer season. However, it is important not to overwater the plant as it can cause root rot and fungal infections, which can damage the plant.

Propagation of Barleria longistyla Lindau
Barleria longistyla Lindau, commonly known as the Long Style Philippine Barleria, is a fast-growing plant that belongs to the Acanthaceae family. Propagation of Barleria longistyla can be done by seed or vegetative methods, including stem cuttings and division.
Propagation via Seeds
Propagation via seeds is the most common method used to propagate Barleria longistyla. Seeds can be obtained from mature fruits that have turned brown, after which they are cleaned and dried for a day. After cleaning, sow the seeds in well-drained soil and cover with a thin layer of sand. Water regularly and place the container in a shaded area with temperatures ranging from 24-30°C. Germination usually occurs within two weeks, and the seedlings can be transferred to a bigger container once they have developed true leaves.
Vegetative Propagation
Propagation via stem cuttings is also a viable method for Barleria longistyla. To propagate through stem cuttings, cut healthy stems from the parent plant, making sure that the cuttings are at least 15-20cm long. Remove the lower leaves and dip the cuttings in rooting hormone before planting them in well-drained soil. Keep the soil moist and place the container in a shaded area. Roots will develop within 4-6 weeks, and the cuttings can be transplanted to a bigger container or directly planted in the ground.
Propagation through division is another method used for Barleria longistyla. This entails dividing the parent plant into smaller sections with at least one root and one stem per section. Plant the divided sections in individual containers containing well-drained soil. Keep the soil moist and place the container in a shaded area. Growth and development will occur within a few weeks, after which the plants can be transferred to larger containers or planted in the ground.
Disease Management
Barleria longistyla Lindau is prone to a few diseases that can be managed if detected early. Here are some common diseases that might affect the plant:
- Leaf Spot: This fungal disease causes small, dark spots on the leaves. To manage it, remove infected leaves and avoid overhead watering.
- Root Rot: This disease is caused by overwatering and poor soil drainage. To protect your plant, make sure the soil has good drainage and avoid overwatering.
- Mildew: This disease causes a white, powdery substance to appear on the leaves. To manage this, you can improve air circulation and avoid overhead watering. There are also organic fungicides that can help.
Pest Management
In addition to diseases, pests can also be a concern for Barleria longistyla Lindau. Here are common pests that might affect the plant and ways to manage them:
- Spider Mites: These tiny pests can be identified by tiny webs on the plant. To manage them, you can try using neem oil or insecticidal soap.
- Caterpillars: These pests can eat the leaves of the plant and cause damage. To manage them, handpick them off the plant or use Bacillus thuringiensis.
- Whiteflies: These pests can be identified by small white insects on the leaves. To manage them, try using yellow sticky traps or insecticidal soap.
