Vegetables that can Magically Regenerate from Kitchen Scraps

To me there is nothing better than when you can get something from nothing! Instead of composting your kitchen scraps, there are some vegetables that can regenerate and be grown again and again. Talk about sustainability! While you are waiting for your indoor seeds to germinate, this activity will yield results in the blink of an eye!

You’ll just need a little bit of time and patience to take care of the new plants and make sure they have the necessary water and sunlight. But the benefits are huge. You will have your own organic vegetable garden with regular supply at essentially no cost! Projects like these are great hands-on experiential learning and gratifying experiments for kids. They can hone their observations skills and watch in wonder as the scraps sprout and regrow. They can record their observations, taking note of physical changes such as color, texture and height. This is also a great way to apply the skill of measurement. Further, kids learn about recycling and how plants grow.

Sounds magical? Let’s get started!

Romaine Lettuce

You can regrow romaine lettuce from the bottom of the stump. Just put the romaine lettuce stumps in half inch of water for a few days. Refill water if the water level is below half an inch. When new leaves start to regrow, you can transfer and plant them in soil.

Carrots Tops

The leaves of carrots are actually edible and you can regrow them by putting carrot tops in water in a well-lit room or a window sill. This is a clever way to turn your carrot scraps into salad. They taste a little like parsley!

Green Onions

Green Onions are probably the easiest vegetables to regrow. You can regrow green onions by cutting them in about an inch from the roots and placing them in a glass of water. These literally regrow in front of your eyes!


Cut the stalk at about 1 to 2 inches from the bottom. Place the remaining stem in a shallow dish of water (about 1/2 inch). Place on a window sill or in a spot with a lot of light. Change the water every 1 to 2 days and voila! Watch the celery grow new shoots.

Sweet Potatoes or Potatoes

You can regrow sweet potato by placing it in a jar of water in direct sunlight and letting it sprout. Make sure only half the potato is immersed in the water. Then plant the well-rooted sprouts in soil.

For potatoes, just leave your spud in a dark corner, forget about it, and it’ll just sprout! Or you can cut a potato in half and place it directly in some soil. Where you see the dented “eyes” on the skin, plant the potatoes in soil with the “eyes” facing up. That’s where the plant will begin to sprout in a couple weeks.

Add some S.T.E.M. (Science Technology Engineering Math) challenges into the mix! Under what conditions do these plants regrow the best? Try manipulating different conditions to see which ones yield the best results!
