Grow Your Own Vegetable Garden From Leftover Scraps Slideshow
Leeks, Scallions, or Green Onions
With leeks, scallions, or green onions, you can simply take the root end of the vegetable and place it in a jar with water, according to Itsafabulouslife.com. Once the roots begin to grow, you can replant into a container.
Greens
Greens — such as celery, bok choy, romaine, and cabbage — work similarly; just place the root end in a bowl of water. While it starts to sprout new leaves and roots grow, spritz the leaves with water to keep them damp. Then replant it in soil, leaving just the leaves showing above the ground.
Garlic
All you need to start growing garlic is one clove. Plant it root down and leave the container in a place with lots of direct sunlight. Once new shoots are established, cut them back so the plant will focus its energy on producing the garlic bulb.
Potatoes
Did your potatoes start sprouting "eyes"? Well, according to Wakeupworld.com, you can take 2-inch-sized pieces that have a couple of eyes and let them dry out. Then plant the pieces 8 inches deep with the eye facing up. You'll want to add more soil as the roots appear. You can do the same thing with sweet potatoes!
