|Store bought bunch of Spring Onions|
Cut off the white parts and roots at the bottom of the spring onion about 4 cms up. Then it's basically the same as for the celery from my last post.
Place them in a jar of warm water and put them outside or in a window with good light. After a couple of days you should see new growth on the green tops.
By about day 5 and they are looking like I could cut some off and use them if I needed too however I think I will leave them to grow some more. However I did notice that the water had started to go a bit cloudy and smelt very oniony so I think that rinsing them each day and changing the water is probably a good idea. I think that after 12 - 14 days you should almost have a completely new bunch and best of all they were completely free!
