Basil. I needed some fresh basil last week and had to buy "living" basil. I stuck the left overs into a pot of dirt. I've been watering it but it isn't looking good. Anyone have any suggestions for me?
Celery! I read in several different places that you could re-grow celery. I think it was originally posted HERE. After two days, I have a couple roots shooting out the bottom. Very cool!
Onions! I also have read about this in several different places.
I'll post an update in a few days. The celery is what I think will be really great if it works.
Are you growing anything inside? Have you tried growing any of the above?
