Mongo beans -- also called mung beans -- are grown primarily for their nutritious sprouts. While mung beans have a high germination rate, it's important to take cleanliness and sanitation into consideration. Mung bean seeds and sprouts often harbour bacteria that cause food-borne illnesses. Proper handling produces safe sprouts and full-grown mongo bean plants.

  1. 1

    Fill a pot with 3 per cent hydrogen peroxide. The hydrogen peroxide level must be high enough to submerge all of the beans.

  2. 2

    Put the pot on the stove at medium heat. Check the temperature of the hydrogen peroxide; it must stay at a constant 60 degrees C (140 degrees F).

  3. 3

    Put the beans in a metal strainer. Lower the metal strainer into the heated hydrogen peroxide and allow it to sit for five minutes. Stir the beans every minute throughout the process to ensure even heating.

  4. 4

    Remove the strainer from the hydrogen peroxide after the five-minute heating period. Place the beans under cool running water to rinse away the peroxide.

  5. 5

    Pour the beans in a large bowl. Add water until the beans are covered with 2.5 cm (1 inch) of water. Discard any beans that float.

  6. 6

    Mix a solution of bleach and water in a bucket or sink. Use 180 ml (3/4 cup) of bleach to 4.5 litres (1 gallon) of water. Soak the planting container in the bleach solution for five minutes to sanitise it. Rinse the container after the soaking period.

  7. 7

    Fill the container with a loose potting soil. Moisten the soil until thoroughly damp, but not soggy.

  8. 8

    Scatter the mongo beans on top of the soil. Lightly cover the beans with additional soil and spritz with water.

  9. 9

    Place the container in a partially sunny area. Keep the soil damp. The beans should germinate within a week.
