I don't think this is going to work - Celery
I have never grown celery but was inspired to at least look into it by a posting by forum member Lathechuck. I found several mentions during an online search of the possibility of rooting and planting the butt end of a celery bunch. I gave it a try as seen in the photo below. Things started out well with visible growth of the top within a day. Unfortunately even after a week's time there was no root development. I removed it from the container shown and treated the bottom with the rooting hormone Indole-3-butyric acid and set the celery butt on a damp paper towel for several days then returned it to the pictured container. Four days further on there is still no significant degree of root development. I will give it a few more days but have little expectation of satisfactory result.
