I tried it with some organic lettuce and lo and behold, it worked!
After just a few days, little leaves were peeking out of the stem of my lettuce.
Being the genius that I am, I decided to plant it in our flowerbed. (lettuce needs dirt for nutrients, right?)
Unfortunately, the birds also need lettuce for nutrients and they ate it right down to the ground and killed it.
I decided to try the same thing with some green onions that I got at the farmer's market, although this time I am keeping them inside.
I put the white ends with roots on them in a jar with some water and.....
The next morning there were green shoots sticking out!
You can see where the new growth is- the dark green part.
Ellie thought they were pretty.
Regardless, I am fascinated by it!
This is what they look like today, the second day they've been in the water.
It's raining today, so the lighting isn't as good.
So, don't throw away your leafy lettuce roots, celery roots or green onion roots. (I bet you could grow leeks too.) Use organic produce. Stick the ends in water and watch them re-grow, and make your money go further!
