Did you know you can grow fresh plants from food scraps you would normally throw away? Many fruits, vegetables, and herbs can be regrown right from your kitchen with just a glass of water or a small pot of soil. It is a fun, almost magical project that saves money, reduces waste, and gives you a steady supply of fresh produce. Even better, it is incredibly beginner friendly. You do not need a garden, special tools, or any gardening experience to start.
Here are 15 easy plants you can grow from kitchen scraps and enjoy at home.
1. Green Onions
Green onions are the easiest plant to regrow. Place the white root ends in a small glass of water on a sunny windowsill. Change the water every few days, and you will see new green tops in just a week. Keep snipping the tops as you need them for cooking. They can keep growing for weeks.
2. Lettuce
Save the base of a romaine or butterhead lettuce after using the leaves. Place it in a shallow dish of water and put it in a sunny spot. Within a few days, new leaves will start growing from the center. After a couple of weeks, you can transplant it to soil for a longer harvest.
3. Celery
Celery is one of the most rewarding plants to regrow. Cut off the bottom 2 inches of a celery bunch and place it in a small dish of water. Change the water every few days and watch new stalks grow from the center. Once roots develop, plant it in soil for an even bigger harvest.
4. Garlic
Plant a single garlic clove in a small pot of soil with the pointed end up. Keep the soil lightly moist and place in bright light. The clove will sprout green shoots, called garlic greens, that taste like mild garlic. They are perfect for salads, soups, and garnishes.
5. Ginger
If your ginger root has small green eyes or sprouts, you can grow it into a new plant. Place a piece in a shallow pot of soil with the eyes facing up. Keep it warm, lightly moist, and in indirect light. Ginger takes time but eventually produces large, fragrant rhizomes you can harvest.
6. Basil
Basil cuttings root quickly in water. Take a 4 inch stem with a few leaves, remove the bottom leaves, and place the stem in a glass of water. Within a week or two, roots will appear. Once they are an inch or two long, plant the cutting in soil for a full basil plant.
7. Mint
Mint regrows beautifully from cuttings. Place a small stem in a jar of water and watch the roots form within days. Mint loves moisture, so it can even continue growing in water for a long time. Move it to soil for a fuller plant that produces leaves for tea, drinks, and cooking.
8. Potatoes
A potato with sprouting eyes is ready to grow into a new plant. Cut it into chunks with at least one or two eyes each, let them dry for a day, and plant in deep soil. With sunshine and steady water, you can harvest fresh potatoes in about 90 to 100 days.
9. Sweet Potatoes
Place a sweet potato in a glass of water with toothpicks holding it up so the bottom half is submerged. Within a few weeks, small shoots called slips will appear from the top. Twist them off, root them in water, and plant in soil to grow your own sweet potatoes.
10. Avocado
Save the seed from a ripe avocado, rinse it gently, and stick toothpicks around the middle. Suspend it over a glass of water with the pointed end up and the rounded end submerged. After a few weeks, you will see roots and a stem grow. It makes a beautiful houseplant.
11. Pineapple
Twist the leafy top off a pineapple, remove the bottom leaves, and place the stem in a glass of water. Within a few weeks, roots will form. Then plant in soil and place in bright light. While pineapple plants take years to produce fruit, they grow into beautiful tropical houseplants.
12. Cilantro
Place cilantro stems with bottom nodes in water until roots develop. Then transfer to soil for a fresh, fragrant herb plant. Cilantro grows quickly and can keep producing leaves for weeks with regular trimming.
13. Cabbage
Save the base of a cabbage or bok choy and place it in a shallow dish of water. New leaves will sprout from the center within a few days. After it has grown enough, transplant to soil for a more productive harvest.
14. Carrot Tops
While you cannot regrow a full carrot, you can grow the leafy tops, which are edible and great in pesto or garnishes. Place carrot tops in a shallow dish of water, and within days, fresh greens will sprout. Move to soil for a bigger plant.
15. Lemongrass
Lemongrass stalks from the store can be regrown easily. Place the bottom of the stalks in a glass of water on a sunny windowsill. Within 2 weeks, you should see new roots and shoots. Transfer to soil for a full lemongrass plant that lasts for years.
