Plant Needs
Sunlight
Full sun exposure required for optimal seed production; tolerates partial shade but yields reduce significantly
Watering
Water deeply when top 2–3 cm of soil is dry; avoid overwatering to prevent root rot and fungal growth
Temperature
Thrives in warm, tropical to subtropical temperatures; sensitive to frost below 10°C, which will kill young plants
Characteristics
- Leaf: Simple, opposite lower leaves, alternate upper leaves; ovate to lanceolate with smooth margins
- Flower: Pale pink, white, or purple tubular flowers, borne in leaf axils
- Fruit: Capsular pods containing small, oval seeds in varied colors (white, brown, black)
Care Guide
Watering
Keep soil consistently moist during active growth and flowering stages to support pod development
Fertilization
Apply balanced organic fertilizer at planting to support early growth. Avoid high-nitrogen fertilizers that promote excessive leaf growth at the expense of seed development
Composted banana peel tea：Steep fully composted banana peels in water for 24 hours; dilute 1:20 for root drench to avoid nutrient burn and odor buildupPruning
- Remove lower yellowing leaves to improve airflow and reduce disease risk
- Pinch back growing tips when plants reach 30 cm tall to encourage branching and increase pod production
- Trim senescent foliage after seed harvest to prepare for crop rotation or garden cleanup
