How simple is this! Grow your own green onions, beginning with a bunch from the grocery. Kitchens, Buy Green, Food, Tasti Recipes, Trim Plants, Years Long, Growing Green Onions, Green Onions Growing, Window Sill Gardens
The next time you have green onions, don't throw away the white ends. Simply submerge them in a glass of water and place them in a sunny window. Your onions will begin to grow almost immediately and can be harvested almost indefinitely. We just use kitchen scissors to cut what we need for meals. I periodically empty out the water, rinse the roots off and give them fresh water.
