Q.Growing Onions
My grandson brought to me a store bought onion that was starting to sprout, that he put into water. Can you plant this onion and will it produce more onions?

You can plant it, but it will not grow more onions. What it will do is grow and then flower. From those flowers, you can collect seeds that you can plant in your garden to grow more onions. Here is more information on growing onion seeds:
