I posted earlier about regrowing onions and though admittedly I still haven’t tried it (I already have an innumerable amount of onions growing) I have started regrowing celery. I read an article about it and just happened to have bought a several bunches of organic celery so I had to give it a try. I took the bunches and chopped off the root about 2 inces up the stalks. Put them in a bowl of water and within 3 days I already started seeing results. It’s really amazing. You MUST try this. Celery is so finicky to grow from seed and takes forever. This gives you a huge jump start. It may be hard to tell from these pictures but I’ve already seen about an 1/8″-1/4″ of growth in just a couple of days.
Look at the center of the bunch in the top left corner. It’s hard to see but that’s all regrowth from 3 days.
