Several days ago I put the ends of two celery bunches in small bowls. I soaked a paper towel with water, so that the celery wasn't sitting in it , which I assumed would make the celery ends rot before they grew anything useful. Ideally I would have preferred to set them in wet sand, but don't have any sand at the moment. Thought I would give this experiment a try, and so far, so good!
Celery is so good for you, and I love to use it in broths, soups and stews. It is high in vitamin K ( I have a bleeding disorder so this one is important to me), is an anti-inflammatory and a good antioxidant. If I have found a way to keep it growing continuously, I would be very, very pleased. I'll keep you posted!
