I'm always trying to grow whatever happens to sprout in my kitchen. Onions, until recently, had always been an enigma. They grew green buds in my kitchen, but as soon as I put them in the garden they withered.
That was, until I learned the secret to growing fresh onions at home from kitchen scraps.
What a breakthrough!
How to grow onions from kitchen scraps, in 3 easy steps:
1) Cut off the bottom of an onion. Cut about 1/2 inch from the bottom - the "hairy" looking side. Use the rest of the onion to cook as your heart desires.
2) Leave the onion stump to dry for a few days. I have a potted plant next to my kitchen sink, where I set the stumps until I'm ready to plant them. There is no magic number for how long to leave them out, so long as they're dried out - I usually wait a week or so.
3) Press the stump about 1 inch down into rich soil and bury any exposed parts. In a few weeks, the onion will start to sprout.
Before long, you'll have a garden of fresh, free onions.
