After our success growing green onions from scraps, we decided to try the same experiment with our celery leftovers. We put the ends right side up in glass dishes and filled them with water to about halfway up the stalk. Once the leaves had grown to about 4-5″ tall we planted them into a pot filled with potting soil mixed with peat.
Hopefully they will continue to grow and we will be able to enjoy a continuous supply of celery through the coming winter. It never ceases to amaze me how much can be grown from things we would have discarded. Very empowering!
