Soil Type

Water: Originating from tropical regions, sword bean flourishes in humid environments with consistent moisture. Weekly watering maintains growth, while brief dryness is tolerated. As an outdoor plant, sword bean benefits from rainwater, enhancing its natural growing season and hydration needs.

Fertilize: Fertilizing sword bean is essential for robust growth and bean production. Use high-phosphorus fertilizers quarterly during the growing season, adjusting for dormancy. Ensure soil is watered before application to prevent root burn. Proper fertilization promotes health and boosts yield, leading to a thriving plant.

Pruning: Sword bean features large, sword-shaped pods and thrives with strategic pruning in early to late spring. Remove dead branches to enhance air circulation, promote growth, and prevent pests. Post-pruning, apply balanced fertilizer for recovery. Consult reliable gardening resources for comprehensive techniques.

Propagation: Sword bean thrives through sowing in moist, well-drained soil with ample sunlight. Enhance germination by softening the seed coats. Maintain moisture without waterlogging, thin seedlings for growth, and handle carefully during transplanting to promote healthy development.
