Mung beans require consistent moisture, especially during their critical flowering and pod development stages. Water deeply once or twice a week, ensuring the soil remains evenly moist but never waterlogged. Good drainage is crucial to prevent root rot. Reduce watering slightly as pods mature and dry, but avoid letting the soil completely dry out for extended periods to ensure optimal yield and plant health.

Mung beans generally require minimal pruning. You can pinch back the growing tips of young plants to encourage bushier growth, which may lead to more pods. Remove any yellowing, diseased, or dead leaves and stems to improve air circulation and plant vigor. This helps prevent fungal issues and directs the plant's energy towards healthy growth and pod development.

Mung beans are primarily propagated by seeds. Sow seeds directly into well-prepared soil after the last frost, when soil temperatures are consistently above 18°C (65°F). Plant seeds about 2.5-5 cm (1-2 inches) deep and 10-15 cm (4-6 inches) apart in rows, with rows spaced 60-90 cm (2-3 feet) apart. Ensure consistent moisture for successful germination, which typically occurs within 5-10 days.

Mung beans are annuals and generally not repotted. If starting seeds indoors in pots, transplant seedlings carefully to their final outdoor location or larger containers once they have developed a few true leaves and the weather is warm enough. Choose a pot at least 20-30 cm (8-12 inches) deep and wide for mature plants to accommodate their root system and support pod development.
