In the spring I put out several sets of shallots, not green onions. They were in the ground all summer but all I got were more little tiny shallots. They didn't grow. What happened? And can I replant these and try again?

It may have been a lack of phosphorous or it may have been heavy soil or it may have been a lack of water. All of these can cause undersized bulbs on shallots. Have your soil tested and amend for phosphorous as needed. If you have heavy soil, try amending with organic rich material like compost. And make sure that your shallots are getting enough water, deeply enough throughout the growing season.
