How to Grow a Bean in Cotton Wool

Planting a bean in cotton wool turns gardening into a simple science project to share with children. To add an extra bit of knowledge to the experience, grow the bean in cotton wool in a clear container or a zippered plastic storage bag so everyone can watch the roots and sprout develop.

Cotton wool is raw and unprocessed, unlike the typical puff balls in a medicine cabinet.

Step 1

Clean and sterilize the container if you have used it before.

Step 2

Line the bottom of the container with cotton wool. If you are using a zippered bag, fill it about halfway with the cotton wool.

Step 3

Water the cotton thoroughly so it is completely saturated but not overly wet. You should not see dry cotton or standing water.

Step 4

Position the beans on the cotton wool. For the zippered bag, lay them between the cotton wool and one side of the bag before sealing the zipper.

Step 5

Place the container in a dry, cool place until the beans sprout and develop at least four leaves.
