Germination of a Mung Bean


Mung beans are grown primarily as sprouts used in cooking. The dried beans are rinsed and placed in a dark, warm, moist environment until they germinate, at which time they split open and a shoot appears.


To germinate, mung beans are washed and rinsed in cold water. They are then drained and placed in a bowl or other container where they are covered in cold water to an amount that is two to three times more than the seeds. They are soaked overnight, drained, rinsed and drained again. The beans are placed in a jar that is covered in cheesecloth and placed in a warm place that doesn't get direct sunlight.

Desired Size

Mung beans can be germinated to different sizes depending on preference. After being rinsed and drained for two or three days, the sprouts will be 1/4 to 1/2 inches long. Extending the process for four or five days will produce sprouts that are from 1 to 3 inches long.


Mung beans sprouts that are fully germinated can be stored under refrigeration in plastic bags for up to three days. Daily rinsing could extend the storage time, and mung beans can be frozen for long-term use.
