We were able to take small celery stalks off of our kitchen scrap surprise for months. They never grew as big as when I bought the celery at the store, but it consistently grew new stalks. They were enough for us to chop up in salads or soups.

The green onion kept us in chives for months as well. Anytime I wanted some chives for my ramen or as a splash of color is salads all I had to do was snip some from my kitchen scrap surprise green onions.
