Water: Fish poison, native to tropical regions, prefers high humidity and tolerates drought. It thrives with watering every 2-3 weeks. As an evergreen, fish poison retains its leaves year-round and needs consistent moisture for vibrant foliage.

Fertilize: For optimal growth, fish poison needs balanced fertilizers, increasing nitrogen during peak growth. Apply quarterly, avoiding over-fertilization. Seasonal adjustments are essential—reduce in winter, increase in the growing season. Always water fish poison after feeding to ensure nutrient distribution and prevent root burn.

Pruning: Pruning fish poison in early spring significantly enhances its growth and flowering. Focus on removing dead branches and thinning dense areas for better air circulation. Cut just above buds to promote new growth. Use clean, sharp tools to prevent infections and reduce disease risk.

Propagation: Fish poison cultivation thrives with semi-hardwood cuttings from healthy, disease-free parent plants. Use rooting hormone for better establishment, well-draining soil to prevent waterlogging, and maintain consistent moisture. Gentle initial care fosters robust growth, enhancing the enjoyment of fish poison's unique attributes.
