"The next time you have green onions, don't throw away the white ends. Simply submerge them in a glass of water and place them in a sunny window. Your onions will begin to grow almost immediately and can be harvested almost indefinitely. We just use kitchen scissors to cut what we need for meals. I periodically empty out the water, rinse the roots off and give them fresh water."

Growing Celery From Discarded Bottoms Its one week old and look at all that celery growing up. Half of the base is submerged in water, and when the celery has roots, you can plant it out in the garden. The celery hasn’t been in direct sunlight, just in the window. Recommend using organic celery.
