WhenI saw this in Pinterest I knew I had to try it..and works!
yes, never again I will be buying green onions!
Just do not throw the white ends in the garbage after using them. Simply put them in water and exposed to lots of light, and soon, very soon the green starts to grow like crazy, and better, when you cut it to use, and it grows again, never stops! And I also like the nice scent it gives.
Just remember to change the water often and you are in for a steady supply of fresh green onions!
