Why won't my garden onions grow larger?
I consider myself having a green thumb, but the one thing I can't do is grow onions as large as the ones in the store. I use yellow or white onion sets, found at the local store, because I love to eat green onions, and they grow fast. However, when I stop harvesting the green onions, my other onions will not grow any larger than an oversized golf ball. What gives? My mom always said not to let the July rains get them, but I have left them in the ground until Sept. sometimes, and still no large onions.
