Mung Bean

Vigna radiata

vegetable

Mung bean (Vigna radiata) is a small, fast, warm-season legume about 2 to 3 ft tall, best known worldwide as the source of crisp bean sprouts and, in South Asia, as the split pulse for dal. The bushy plants set slender pods that ripen unevenly to brown or black over a long window. It is frost tender and heat loving, drought tolerant once established, and like other legumes it fixes nitrogen, making it a useful rotation or green-manure crop. Mung beans can be eaten as dried beans, sprouted, ground into flour, or harvested as young pods.

✅ Plant alongside

Good neighbors that attract beneficial insects or deter pests

• Corn — Tall stalks offer light support and partner well with a nitrogen fixer
• Cucumber — Sprawling vines shade the soil while the beans enrich it
• Marigold — Helps deter nematodes and draws beneficial insects

• Aphids →

  Cluster on shoots and can spread virus; rinse off and conserve natural enemies

• Bean beetle →

  Beetles and larvae chew leaves; handpick and check leaf undersides for eggs

  White coating in humid crowding; space for airflow and avoid overhead watering

• Root-knot nematodes →

  Stunt plants via root galls; rotate crops and add organic matter

🌾 Harvest & storage

For dried beans, harvest when the pods turn brown or black and dry; because they ripen unevenly, either pick mature pods in several passes or pull whole plants once most pods have dried and finish them under cover. Thresh out the small seeds and store airtight. For sprouts, soak dried beans and rinse them several times a day in a jar until the white shoots are crisp and a couple of inches long.

🥗 Nutrition & benefits

Mung beans are high in plant protein, fiber, folate, and minerals, and are very digestible. They are eaten as dal, as fresh sprouts, and ground into flour for noodles and batters.
