In thé window of thé small stairwell off the back of the house that leads to the land where the dogs can roam free, and every tormenting hour of being locked up in a cage is released, this is where I have grown green onions over the past two weeks, from Groundswell Community Farm. I simply take the root ends from my green onions, and I put them in a cup of water in the windowsill. I would recomend changing the water everyday, or they may begin to rot. The rooting green onion root is awfull!
