If you’re looking for ways to save money, reduce food waste, and enjoy an endless supply of fresh produce, look no further than your own kitchen scraps.
With just a bit of water, sunlight, and patience, you can regrow many healthy foods right at home — even if you don’t have a garden.
Regrowing food from scraps is one of the easiest ways to create a sustainable kitchen. It’s cost-effective, beginner-friendly, and a great project for anyone who wants to become more self-reliant.
Whether you live in a house with a backyard or a small apartment with a windowsill, these 12 healthy foods can be regrown at home forever.
1. Green Onions
Green onions (also known as scallions) are one of the easiest vegetables to regrow. All you need is the white root base of the plant.
How to regrow:
-
Save the bottom 1–2 inches of the green onion with the roots intact.
-
Place it in a glass of water with the root side down.
-
Set it on a sunny windowsill and change the water every 2–3 days.
-
New shoots will begin growing within a few days. Harvest as needed.
2. Garlic
Garlic is not only a staple in most kitchens but also has powerful immune-boosting properties. You can regrow garlic easily from a single clove.
How to regrow:
-
Plant a garlic clove, root-end down, in a small pot of soil.
-
Keep the soil moist and place it in a sunny spot.
-
In a few weeks, you’ll see green garlic shoots, which you can trim and use like scallions.
-
If you let it continue growing, it will eventually form a full bulb.
3. Lettuce
Leafy greens like romaine and butterhead lettuce can regrow from their base. This is a great way to always have salad greens on hand.
How to regrow:
-
Save the bottom 2 inches of a lettuce head.
-
Place it in a shallow bowl with water, cut side up.
-
Change the water every 2–3 days.
-
In about 7–10 days, new leaves will begin to grow. You can transplant it into soil for continued growth.
4. Celery
Celery is packed with antioxidants and vitamins, and it regrows just like lettuce.
How to regrow:
-
Cut the base of the celery (about 2 inches) and place it in a shallow bowl of water.
-
Keep it in a sunny spot and change the water regularly.
-
New growth will start from the center, and once roots appear, you can plant it in soil.
5. Basil
Fresh herbs like basil are expensive in stores but easy to grow from clippings.
How to regrow:
-
Cut a 4–6 inch basil stem just below a leaf node.
-
Remove the bottom leaves and place the stem in a glass of water.
-
Roots will begin to form in about 7–10 days.
-
Once rooted, transfer to a pot with soil and enjoy fresh basil indefinitely.
6. Carrot Greens
While you can’t regrow the carrot root itself, the leafy tops are edible and packed with nutrients. They can be used in soups, pesto, or as a garnish.
How to regrow:
-
Save the carrot tops with a bit of the root attached.
-
Place the cut side down in a shallow dish with water.
-
In a few days, green tops will begin to sprout.
-
Optional: transplant to soil for a longer harvest.
7. Ginger
Ginger is anti-inflammatory and excellent for digestion. It’s also surprisingly easy to grow from a piece of root.
How to regrow:
-
Choose a plump piece of ginger with visible “eyes” or growing buds.
-
Soak it overnight in warm water.
-
Plant it in a pot with the buds facing up, and cover with soil.
-
Keep in a warm, humid spot.
-
Shoots and roots will grow in a few weeks.
8. Potatoes
With the right care, one potato can turn into a whole crop.
How to regrow:
-
Use organic potatoes with “eyes” or sprouts.
-
Cut into chunks (each with at least one eye) and let them dry for 1–2 days.
-
Plant the chunks in soil, 4 inches deep.
-
As they grow, mound soil around the base to encourage more tuber formation.
9. Sweet Potatoes
Sweet potatoes are loaded with fiber, vitamins, and antioxidants, and can also be regrown with minimal effort.
How to regrow:
-
Cut a sweet potato in half and suspend it in water using toothpicks.
-
Roots will grow from the bottom, and slips (sprouts) will form on top.
-
Once slips reach 5–6 inches, remove them and plant in soil.
-
New sweet potatoes will form underground as the plant matures.
10. Lemongrass
Lemongrass is a fragrant herb with many health benefits, especially for digestion and inflammation. It’s perfect for tea or cooking.
How to regrow:
-
Place the bottom few inches of a lemongrass stalk in water.
-
Put in a sunny window.
-
Roots will develop within a week or two.
-
Once rooted, plant in soil for continuous harvest.
11. Leeks
Like green onions, leeks can regrow from their white root ends.
How to regrow:
-
Save 2 inches of the white base with the roots.
-
Place in a glass of water in a sunny spot.
-
Replace water regularly.
-
Within a week, you’ll see new growth from the center.
12. Chives
Chives are a hardy herb that regrow quickly and can be harvested year-round with proper care.
How to regrow:
-
Dig up or buy a clump of chives with roots attached.
-
Plant them in a pot with nutrient-rich soil.
-
Keep them well-watered and place in a sunny location.
-
They will continue producing leaves indefinitely.
Tips for Success
-
Use organic produce whenever possible, especially for root crops like potatoes or ginger, which may be treated with growth inhibitors.
-
Change water regularly when growing in jars or glasses to prevent rot or mold.
-
Provide sunlight — a bright windowsill or grow light will keep your regrown plants healthy.
-
Transplant into soil for long-term harvesting. Water and feed occasionally with organic fertilizer.
-
Harvest lightly — let the plant establish before taking large cuttings.
