In an era where sustainability and self-sufficiency are gaining traction, regrowing vegetables from kitchen scraps is a practical and eco-friendly way to reduce waste and cultivate your own food. Many common vegetables can be regrown from parts you might otherwise discard, such as stems, roots, or seeds. This practice not only saves money but also fosters a deeper connection to the food we eat. Below, we explore ten vegetables you can easily regrow from kitchen scraps, complete with step-by-step instructions and tips for success.
1. Green Onions (Scallions)
Green onions are one of the easiest vegetables to regrow, requiring minimal effort and space. The white bulbous base with roots can sprout new shoots when placed in water or soil.
How to Regrow:
- Step 1: Cut off the green tops, leaving about 1-2 inches of the white base with roots intact.
- Step 2: Place the root end in a shallow glass of water, ensuring the roots are submerged but the top is exposed. Change the water every 2-3 days.
- Step 3: Within a week, new green shoots will emerge. Harvest as needed or transplant into soil for continuous growth.
Tips:
- Grow in a sunny windowsill for best results.
- If planting in soil, ensure it’s well-draining to prevent rot.
- Harvest regularly to encourage new growth.
Green onions are versatile, adding a mild onion flavor to salads, soups, and stir-fries, making them a kitchen staple worth regrowing.
2. Lettuce
Lettuce scraps, particularly from romaine or leaf varieties, can be regrown into small heads or harvested for baby greens.
How to Regrow:
- Step 1: Save the bottom 2 inches of a lettuce head after removing the leaves.
- Step 2: Place the base in a shallow dish with about half an inch of water. Position it in a sunny spot and change the water daily.
- Step 3: Within 3-5 days, new leaves will sprout from the center. After 10-14 days, transplant into soil for fuller growth or continue in water for smaller leaves.
Tips:
- Romaine lettuce works best for regrowing full heads.
- Avoid submerging the entire base to prevent rot.
- Harvest outer leaves to prolong the plant’s life.
Regrowing lettuce is ideal for small spaces, providing fresh greens for salads or sandwiches with minimal effort.
3. Celery
Celery bases can regenerate stalks, offering a steady supply for soups, snacks, or salads.
How to Regrow:
- Step 1: Cut off the stalks, leaving the bottom 2 inches of the base.
- Step 2: Place the base in a shallow bowl with enough water to cover the bottom but not the top. Keep it in a bright area and refresh the water every couple of days.
- Step 3: After 5-7 days, new stalks and leaves will appear. Transplant into moist, fertile soil, covering the base but leaving the new growth exposed.
Tips:
- Ensure the soil stays consistently moist but not waterlogged.
- Celery prefers cooler temperatures and partial shade.
- Harvest outer stalks to encourage continuous growth.
Regrown celery may not be as thick as store-bought, but it’s equally flavorful and perfect for home cooking.
4. Potatoes
Potatoes can be regrown from scraps with “eyes” (small sprouts), making them a rewarding crop for gardeners.
How to Regrow:
- Step 1: Select a potato with visible eyes. Cut it into chunks, ensuring each piece has at least one or two eyes.
- Step 2: Let the chunks dry for 1-2 days to prevent rotting.
- Step 3: Plant the pieces 4 inches deep in well-draining soil, with the eyes facing up. Water regularly and mound soil around the stems as they grow.
- Step 4: Harvest after 2-4 months when the foliage dies back.
Tips:
- Use organic potatoes, as non-organic ones may be treated with sprout inhibitors.
- Grow in a sunny spot with loose, fertile soil.
- Small potatoes can be harvested earlier for “new” potatoes.
Potatoes are a staple crop, and regrowing them reduces reliance on store-bought supplies.
5. Carrots
While you can’t regrow the edible carrot root, the greens can be regrown from carrot tops for use in salads, pesto, or garnishes.
How to Regrow:
- Step 1: Cut off the top 1 inch of a carrot, including the green stem base if present.
- Step 2: Place the cut side down in a shallow dish with a small amount of water, ensuring the top remains above water. Keep in a sunny spot and change water daily.
- Step 3: Within a week, green shoots will emerge. Transplant into soil for continued growth or harvest greens directly.
Tips:
- Use fresh, organic carrots for best results.
- Carrot greens are slightly bitter but nutritious and flavorful in small quantities.
- If planted in soil, ensure good drainage to avoid rot.
Carrot greens add a unique twist to dishes, making this a fun and sustainable project.
6. Garlic
Garlic cloves can be planted to grow new bulbs, offering a low-maintenance way to produce homegrown garlic.
How to Regrow:
- Step 1: Select a single garlic clove with its papery skin intact.
- Step 2: Plant the clove root-end down, about 2 inches deep in well-draining soil, in a sunny location.
- Step 3: Water sparingly, keeping the soil moist but not soggy. After 6-9 months, harvest when the lower leaves turn brown.
Tips:
- Plant in fall for a summer harvest or spring for a smaller yield.
- Use organic garlic, as treated cloves may not sprout.
- Garlic scapes (green shoots) can be harvested earlier and used in cooking.
Homegrown garlic is more flavorful than store-bought and can be replanted year after year.
7. Ginger
Ginger roots can be regrown to produce fresh rhizomes, ideal for cooking or brewing tea.
How to Regrow:
- Step 1: Choose a piece of ginger with visible “eyes” or buds.
- Step 2: Soak the piece in water overnight to encourage sprouting.
- Step 3: Plant it 2 inches deep in rich, well-draining soil, with the buds facing up. Keep in a warm, partially shaded spot and water regularly.
- Step 4: Harvest after 8-10 months when the stems die back, or dig up small pieces as needed.
Tips:
- Ginger thrives in warm, humid conditions.
- Use a pot for easier harvesting and to control growth.
- Be patient, as ginger grows slowly.
Fresh ginger adds a zesty kick to dishes, and regrowing it is a cost-effective option.
8. Leeks
Similar to green onions, leeks can be regrown from their root ends, producing new stalks for cooking.
How to Regrow:
- Step 1: Cut off the green tops, leaving 1-2 inches of the white base with roots.
- Step 2: Place the base in a glass with enough water to cover the roots. Change water every 2 days and keep in a sunny spot.
- Step 3: New growth will appear within a week. Transplant into soil for larger leeks or continue in water for smaller harvests.
Tips:
- Leeks prefer cooler temperatures and rich soil.
- Harvest when stalks are thick enough for your needs.
- Regrown leeks are milder but still delicious in soups or roasts.
Leeks are a versatile allium, making them a great addition to your regrowing repertoire.
9. Basil
Basil cuttings can be rooted to grow new plants, providing fresh herbs for cooking.
How to Regrow:
- Step 1: Cut a 4-inch stem from a healthy basil plant, just below a leaf node.
- Step 2: Remove lower leaves and place the stem in a glass of water, ensuring the node is submerged. Keep in a bright spot and change water every 2 days.
- Step 3: Roots will form in 1-2 weeks. Transplant into soil once roots are 2 inches long.
Tips:
- Pinch off flower buds to encourage leaf growth.
- Basil loves warmth and sunlight, so place it in a sunny spot.
- Harvest regularly to keep the plant bushy.
Fresh basil enhances pastas, pizzas, and salads, making it a must-have for herb enthusiasts.
10. Sweet Potatoes
Sweet potato scraps can produce slips (sprouts) that grow into new plants, yielding more tubers.
How to Regrow:
- Step 1: Select a sweet potato and place it in a jar of water, with half submerged, using toothpicks to suspend it. Keep in a warm, sunny spot.
- Step 2: Change water weekly. Within 2-4 weeks, slips will sprout from the top.
- Step 3: Remove slips when they’re 6 inches long and root them in water or plant directly in soil. Harvest tubers after 4-6 months.
Tips:
- Sweet potatoes need warm weather and well-draining soil.
- Plant in a large container or garden bed for best results.
- Use organic sweet potatoes to avoid sprout inhibitors.
Sweet potatoes are nutritious and versatile, perfect for roasting, mashing, or baking.
