# Spring Onions If you buy spring onions then it's possible, like us, that you buy them in a bundle and end up with half of them drying out in the refrigerator. Well, you can prolong their life by keeping them growing. ## Method Get a glass jar and place the onions inside (root down). Fill the jar with enough water to cover 3 inches or so of the onions. Place the jar on a window ledge and leave for a 3 to 5 days. After this time you should start to notice the roots growing back (if they have been trimmed). Once the roots have grown 20mm or so you can plant them in soil outdoors and they will continue to grow until you need them. This same method should also work for leeks.
