It can grow in both tropical and subtropical climates, as long as it is protected from frost and extremely high temperatures. The plant thrives in warm and humid environments, with an ideal temperature range between 20°C to 30°C. If temperatures exceed 35°C, it may cause the plant to wilt and eventually die.
Soil Requirements
Orthosiphon rufinervis G.Taylor grows best in well-draining soil that is rich in organic matter. The soil should be slightly acidic with a pH range of 6.0 to 7.0. The plant prefers loamy or sandy soils that are nutrient-rich, but it can still grow in clay soils as long as proper drainage is provided. It is also important to note that Cat's Whiskers requires consistent moisture, but the soil should not become waterlogged.
Overall, Cat's Whiskers is a hardy plant that can grow in a variety of conditions, as long as it receives adequate sunlight, is protected from frost and extreme temperatures, and is planted in well-draining soil that is moist and rich in nutrients.
Cultivation methods
Orthosiphon rufinervis G.Taylor, commonly known as purple head, is a tropical plant that thrives in warm climates with temperatures between 18°C and 35°C. It grows best in well-drained soil with a pH range of 6.6-7.8. When planting, ensure the roots are not exposed to air. The plant requires partial shade to full sun, and it's advisable to plant it in an area where it can get direct sunlight for at least six hours a day.
Watering needs
Orthosiphon rufinervis G.Taylor requires adequate water, especially during the growing season. For best results, water the plant deeply, ensuring the soil is moist but not waterlogged. Reduce watering during the dormant season to avoid root rot or fungal infections. Alternatively, you can use a drip irrigation system or a watering can to ensure the plant gets enough water.
Fertilization
Orthosiphon rufinervis G.Taylor needs fertilizer to thrive, and it's advisable to use a balanced, all-purpose fertilizer with an NPK ratio of (10:10:10). Fertilize the plant once a month, but reduce the frequency during the dormant season. Overfertilizing the plant can lead to leaf burn, stunted growth, or fertilizer burn, while under-fertilizing can lead to poor growth and nutrient deficiency.
Pruning
Orthosiphon rufinervis G.Taylor requires regular pruning to maintain its shape and promote healthy growth. Pruning also helps to get rid of dead and diseased branches. Use a sharp, sterilized pruning shears to avoid damaging the plant, and prune above a leaf node. Pruning can be done at any time, but it's advisable to do it during the growing season to prevent stunted growth and nutrient loss.
Propagation of Orthosiphon rufinervis G.Taylor
Orthosiphon rufinervis G.Taylor, commonly known as cat's whiskers, is a perennial herb that belongs to the family Lamiaceae. It is native to Southeast Asia and has been widely used in traditional medicine for various purposes, including the treatment of kidney stones, high blood pressure, and diabetes. If you want to grow this plant, the following propagation methods can be used:
1. Seed propagation
One of the easiest ways to propagate Orthosiphon rufinervis is through seeds. The seeds of this plant are very small and can be sown in trays or pots filled with seed-raising mix. The seeds should be lightly covered with soil and kept moist until germination, which usually takes about 2-3 weeks. Once the seedlings are big enough to handle, they can be transplanted into individual pots and grown until they are large enough to be planted in their final positions.
2. Stem cutting propagation
Orthosiphon rufinervis can also be propagated through stem cuttings. The best time to take cuttings is in spring or early summer when the plant is actively growing. Select a healthy stem that is about 10-15 cm long and has several leaves. Remove the lower leaves and cut the stem just below a node. Dip the cut end of the stem in rooting hormone powder and place it in a pot filled with a well-draining potting mix. Keep the soil moist and the cutting in a warm, bright location. After a few weeks, roots should start to form, and new growth will emerge from the top of the cutting.
3. Division propagation
Orthosiphon rufinervis can also be propagated through division. This method is best done in the early spring when the plant is starting to grow again. Dig up the plant carefully and separate the root clumps into smaller sections, ensuring that each section has some healthy roots and shoots. Replant the divided sections in their final position, and water them well for the first few weeks until they are established.
With the proper care, Orthosiphon rufinervis can be easily propagated and grown in your garden or as a potted plant.

This article outlines some of the common diseases and pests that might affect Orthosiphon rufinervis and ways to manage them.
Common Diseases
One of the most common diseases that affects Orthosiphon rufinervis is root rot. This disease is caused by waterlogged soil and can cause the plant's roots to decay, leading to stunted growth and yellowing leaves. To prevent root rot, avoid over-watering the plant and ensure proper drainage in the soil. If root rot does occur, remove affected plants and treat the soil with a fungicide to prevent it from spreading.
Another disease that can affect Orthosiphon rufinervis is powdery mildew. This fungal disease appears as a white powdery coating on the plant's leaves and stems and can cause them to wither and die. To manage powdery mildew, remove affected leaves and stems and treat the plant with a fungicide. Ensure that the plant has adequate air circulation to prevent the disease from spreading.
Common Pests
Orthosiphon rufinervis can also be affected by several pests, including spider mites and aphids. Spider mites are tiny insects that feed on the plant's leaves and can cause yellowing and wilting. To manage spider mites, spray the plant with a strong blast of water to dislodge the insects from the leaves. Alternatively, treat the plant with insecticidal soap or neem oil.
Aphids are another common pest that can affect Orthosiphon rufinervis. These insects feed on the plant's sap and can cause stunted growth and deformities. To manage aphids, use a strong jet of water to dislodge them from the plant or treat the plant with insecticidal soap or neem oil.
Conclusion
Orthosiphon rufinervis G.Taylor is a versatile plant that can thrive in a variety of conditions. However, it is vulnerable to several diseases and pests that can negatively impact its growth and yield.
