Lettuce salads are healthy, tasty and easy to make. As you are making a salad you cut off the root of the plant and toss it in the trash or compost. These little root nubs can be used to successfully grow new plants that can be eaten in salad again. You can save money growing these roots for new food and it can also be a fun project for kids to do and learn about plants.
When you buy lettuce from a store the bottom of the lettuce head is cut off and toss it out. Instead of tossing it you can take that lettuce root nub and place it in a small amount of water. The lettuce root will grow some new lettuce to be used again.
Onion greens can be grown into new onions by placing the onion into a clear glass with just enough water to cover the roots. Every few days you will need to replace the water. You can cut off the onion greens and use them in your salads and cooking. Then the greens will grow up for use again in about a week. These onion greens are good for soups, stir-fries and salads.
Celery is a fun crop to grow from the root. You can use the celery stalks but leave the root nub intact. Then place the root nub into a glass of water that just covers the root part of the celery and it will start to grow. Once some roots have developed you can replant the celery into soil and it ill grow into a new celery plant that you can use again. The new plant will grow from the center of the celery root.
Ginger roots have little eyes on them that can be cut off and grown into a new ginger plant. Cut an eye off of a ginger and plant it two inches down in soil with the eye facing up. Plant it in direct sunlight and water it regularly. A ginger plant will start to grow with pretty leaves. Leave your ginger root to grow for at least four months but it could stay growing for as long as eight months. Dig up the ginger root and cut off the plant. Cut off a couple eyes from the new ginger root that you just harvested and place them back into the pot of soil and let it grow all over again. Ginger is a fun plant to regrow and use in many ways from stir-fries to tea.
