Imagine growing a thriving vegetable garden using scraps from your kitchen—without having to buy seeds or starter plants again.
Sound too good to be true? It’s not. Many common vegetables can be regrown from store-bought scraps, making your grocery store haul a long-term investment in self-sufficiency.
Whether you’re working with a backyard garden, a balcony, or just a sunny kitchen windowsill, you can buy these vegetables once and regrow them forever with a little patience and care.
In this article, we’ll explore the top 10 vegetables that regrow easily from kitchen scraps and how to do it the right way.

Let’s dive into 10 of the best vegetables you can buy once and regrow endlessly.
1. Green Onions (Scallions)
Why it’s great:
One of the easiest vegetables to regrow, green onions thrive in water and regenerate quickly.
How to regrow:
-
Save the white root ends (about 1–2 inches).
-
Place them in a glass with enough water to cover the roots.

Set on a sunny windowsill and change the water every few days.
-
In just a week, you’ll have fresh shoots ready to harvest.
Tip: After a few regrowth cycles, transplant into soil for long-term yields.
2. Celery
Why it’s great:
Celery regenerates easily from the base and grows well in water or soil.
How to regrow:
-
Cut the base (2 inches) from a celery stalk.
-
Place it in a shallow bowl with warm water, root-side down.
-
Leave it in a sunny window and mist the top daily.
-
Once new leaves appear (within a week), transplant into soil for full regrowth.
3. Lettuce (Romaine, Butterhead, or Leaf Lettuce)
Why it’s great:
Lettuce scraps can regrow fresh leaves quickly, ideal for salad lovers.
How to regrow:
-
Cut the base of the lettuce head (1–2 inches).

4. Garlic
Why it’s great:
Each garlic clove can become a full bulb, giving you endless garlic.
How to regrow:

Plant in soil with the pointy end facing up, 2 inches deep.
-
Water regularly and keep in full sun.
-
In a few months, harvest your garlic bulb and repeat the process.
Bonus: Let one clove sprout and use its greens as garlic chives.
5. Potatoes
Why it’s great:
Just one sprouting potato can lead to a new harvest of fresh tubers.
How to regrow:
-
Use organic potatoes with eyes (sprouts forming).
-
Cut into chunks, each with 1–2 eyes, and dry for 1–2 days.
-
Plant 4 inches deep in loose soil, eyes up.

As the plants grow, mound soil around the stems to increase yield.

Set in sunlight and change water every few days.

Keep in a sunny window and refresh water regularly.
