A few weeks ago i attempted a project to take the base of store bought celery and regrow it.
So far, as you can see in the picture, it is working splendidly. It is doing so well, I thought lets try this with green onions. Again, as you can see next to the celery, success.
I am anxious to get everything outdoors and see how they continue to grow. Now to get some lettuce and more onions started.
