Best Kitchen Scraps to Regrow at Home
1. Green Onions (Scallions)
How to regrow: Place the white root end in a glass of water. Within 3–5 days, green shoots will reappear.
Pro tip: Change the water every two days and move to soil after one week for stronger regrowth.
2. Lettuce and Cabbage
How to regrow: Place the base in a shallow bowl with water and keep it in sunlight. New leaves will sprout from the center in 7–10 days.
Keep in mind: Only regrows once or twice, but great for salad toppings or garnish.
3. Celery
How to regrow: Set the root base in water for a week until leaves sprout. Then plant it in soil for full regrowth.
Why it’s great: Celery is water-rich and very rewarding to regrow with kids.
4. Basil and Mint
How to regrow: Cut a 4-inch stem and place in water until roots develop. Once they reach about 2 inches, plant them in soil.
Quick tip: Keep away from drafts and give them indirect sunlight.
5. Garlic Sprouts
How to regrow: When garlic cloves sprout, plant them in soil with the sprout facing up. In a few weeks, you’ll have garlic greens to harvest.
Bonus: Garlic greens taste like mild scallions and are perfect in stir-fries.
6. Carrot Tops
How to regrow: Place the top of a carrot in water and watch leaves sprout. Great for making pesto or garnishes.
Note: You won’t regrow the root, but the green tops are totally edible!
How to Start Your Scrap Garden
1. Use clear glass jars or bowls to monitor root growth
2. Place containers on a sunny windowsill or balcony
3. Change the water every 1–2 days to prevent mold
4. Transfer to soil once roots or shoots are established
5. Water and trim regularly to keep plants healthy
🌿 For best results, use organic scraps. Conventional produce may be treated with growth inhibitors.
Tips to Maximize Success
- Label each jar with the regrowth date
- Use rainwater or filtered water if available
- Compost leftovers that can’t be regrown (like citrus peels)
- Grow in upcycled containers to further support zero-waste habits
- Get the kids involved—it’s educational and fun!
