Don’t Toss Those Green Onions! 9 Foods You Can Regrow From Kitchen Scraps

Q: Can all vegetables be regrown from kitchen scraps?

No. While many vegetables and herbs — like green onions, celery, lettuce, basil and ginger — regrow easily from scraps, others (root vegetables like carrots or mature fruiting plants) may not produce full replacements from scraps.

Q: How long does it take for regrown scraps to produce usable food?

Timing varies: quick greens (green onions, lettuce, carrot tops) show new growth in days to weeks; herbs take weeks to root and bulk up; potatoes, ginger and pineapple may take months to a year or more for significant harvests.

Q: Do regrown plants need soil or will water alone work?

Many scraps will sprout roots in water and can be harvested for greens that way, but for sustained growth and larger yields you should transplant rooted cuttings into potting soil for nutrients and stability.

Q: Are there special tips to prevent rotting when regrowing scraps?

Yes. Use fresh, healthy scraps, change water every few days if rooting in water, allow cut surfaces to dry slightly before planting, and avoid overwatering once in soil to reduce rot and fungal issues.

Q: Can regrowing scraps save me money and reduce waste?

Absolutely. Regrowing common kitchen scraps can lower grocery costs for herbs and some vegetables, extend produce life, and significantly reduce food waste from your kitchen.

Foods You Can Regrow From Kitchen Scraps — Easy Tips

Before you drop those food remnants into the compost or trash, pause — many can sprout into usable produce right on your windowsill. Re-growing kitchen scraps is an easy way to cut costs, minimize food waste and cultivate a tiny home garden. Below are nine typical kitchen scraps you can revive at home, no gardening expertise needed.

Green Onions

Green onions are one of the simplest items to regrow. Place the white root ends in a jar of water and situate them by a sunny window. New green shoots appear in just a few days. Refresh the water every couple of days and trim what you need.

Celery

Don’t throw out the base of the celery stalk! Place the bottom inch or so in a shallow dish of water and put it in a bright spot. Within about a week, new leaves will start emerging from the center. When it’s sturdier, transplant it into potting soil.

Lettuce

Romaine, butterhead or leaf lettuce can be regrown from the stem. Keep the bottom 2 inches submerged in water and, in roughly a week, new leaves should sprout. This works best when using fresh, crisp scraps.

Potatoes

Those sprouting potatoes tucked away in the pantry are ideal for regrowth. Slice them into pieces ensuring each section has at least one “eye” and let the cut surfaces dry for a day. Then plant them in soil with the eye facing upward. In several months you could harvest new potatoes.

Garlic

Garlic cloves that begin to sprout are ready for planting. Push a single clove into potting mix with the pointed end up and the root end down. Keep it in a bright spot and water lightly. Over time it will form a new bulb — saving you a trip to the market.

Basil

Leftover basil stems can be revived by placing a 4-inch cutting in water, removing leaves from the lower section. When roots develop — usually in about a week — move the cutting into soil. With a bit of attention you can enjoy fresh basil throughout the year.

Carrot Tops

You can’t regrow a whole carrot from the top, but you can grow flavorful greens ideal for garnishes, pesto or smoothies. Place the carrot tops in a shallow dish of water and new foliage will reappear within a few days.

Pineapple

You can indeed grow a pineapple from its crown. Remove the leafy top, strip off a few of the lower leaves, and let the crown dry for a day or two. Plant it in soil in a sunny spot. It requires patience — sometimes up to two years — but it’s a fun project.

Ginger

Pieces of ginger root can be propagated by planting a segment with its growth buds facing upward in moist, warm soil. Maintain steady moisture and warmth, and shoots and roots will begin to form. Ginger grows slowly, but it’s gratifying — and tasty.
