🌱

☀️

Sunlight Full sun to partial shade; requires at least 6 hours of direct sunlight for optimal pod production

💧

Watering Water deeply when the top 2–3 cm of soil is dry; avoid overwatering to prevent root rot and fungal growth

🌡️

Temperature Thrives in 18–27°C; young plants are frost-sensitive, so avoid exposure to temperatures below 10°C

🛠️

Watering

Keep soil consistently moist during pod development to prevent pod drop

Fertilization

Apply balanced granular fertilizer at planting. Avoid excessive nitrogen fertilizer, which can promote leaf growth over pod development

Eggshell powder top-dressing：Crush dried eggshells into fine powder; sprinkle 1–2 tbsp around base of plants to add calcium to soil

Pruning

Pinch growing tips of climbing varieties to encourage branching and increase pod yield
Remove yellowing or diseased leaves to improve airflow and reduce pest risk
Harvest pods regularly (every 2–3 days) to stimulate continued flowering and fruiting
