Mung Bean

Mung beans prefer well-draining soil with a slightly acidic pH between 6.0 and 7.0. The soil should be loose, fertile, and rich in organic matter. Mung beans require full sun and warm temperatures, with a minimum soil temperature of 60°F for germination. In hotter climates, mung beans can benefit from some afternoon shade to prevent heat stress. Overwatering should be avoided as it can lead to root rot, and the soil should be kept consistently moist but not waterlogged. Mung beans can be grown in containers or directly in the ground, and they are a great option for small-space gardening or intercropping with other crops.

After the danger of frost has passed and daytime soil temps average at least 60 degrees, sow seeds 1" deep, 2” apart in rows 36” apart. Avoid planting when cool, wet weather is forecast as this can increase the occurrence of fungal diseases and damping off.

Insect Pests

Mung beans can be attacked by several insect pests, including aphids, bean beetles, thrips, and whiteflies. These pests can damage the leaves, pods, and stems of the plant, leading to reduced growth and yield. To control these pests, use physical barriers or insecticidal soaps, neem oil, or other organic insecticides. Regularly inspect the plants for signs of insect activity and remove any infested plant parts. Introducing beneficial insects, such as ladybugs or lacewings, can also help control pest populations.

Diseases & Other Problems

Mung beans are prone to diseases like powdery mildew, root rot, bacterial blight, and mosaic virus. To prevent these issues, ensure well-draining soil, avoid overwatering, and plant disease-resistant varieties. Regularly inspect the plants for signs of disease or insect activity and remove any infested plant parts. Proper crop rotation and avoiding overhead watering can also help prevent problems in mung beans.

To harvest mung beans, wait until the pods are plump and the seeds are fully developed and the pods are a blackish color, then pick individual pods or alternatively, cut the entire plant and remove the pods. Spread the pods out in a dry, well-ventilated area to dry completely, then remove the seeds from the pods. Store the dried seeds in an airtight container in a cool, dry place away from direct sunlight.

CONSIDERATIONS:

Mung beans are mostly self-pollinating and do not require isolation to prevent cross-pollination. However, if you are growing multiple varieties of mung beans in close proximity, there is a possibility of cross-pollination, which can affect the characteristics of the next generation of plants. To prevent cross-pollination, plant different varieties at least 25-30 feet apart or use physical barriers, such as netting or row covers. Additionally, stagger the planting times of different varieties to avoid overlapping flowering periods.

HARVESTING SEED:

To harvest mung beans, wait until the pods are plump and the seeds are fully developed and the pods are a blackish color, then pick individual pods or alternatively, cut the entire plant and remove the pods. Spread the pods out in a dry, well-ventilated area to dry completely, then remove the seeds from the pods. Store the dried seeds in an airtight container in a cool, dry place away from direct sunlight.

SEED LONGETIVITY:

Mung bean seeds can maintain their viability for up to 3-5 years if stored properly in a cool, dry place with low humidity.
