Let’s turn your kitchen scraps into something delicious.
Why Grow from Scraps?
Growing food from scraps is:

Beginner-friendly – minimal tools or gardening experience needed
Great for kids & families – a fun way to learn where food comes from
Perfect for small spaces – most scraps grow in water or tiny containers
Vegetables You Can Easily Regrow from Scraps
Below are some of the easiest kitchen scraps to grow—plus step-by-step instructions for each one.
1. Green Onions (Scallions)
Skill Level: Easiest
Time to see growth: 24–48 hours
Green onions are the most beginner-friendly crop to regrow.
How to grow:
Save the white root ends (about 1–2 inches long). Place them in a glass with enough water to cover the roots. Put the glass near a sunny window. Change the water every 2–3 days.
What to expect:
New green shoots will grow almost instantly. You can trim what you need and they’ll keep regrowing for weeks.
2. Lettuce, Bok Choy & Celery
Skill Level: Easy
Time to see growth: 3–5 days
These greens are great for beginners and regrow surprisingly well.
How to grow:
Save the base (the root end) after cutting. Place it in a shallow dish with ½ inch of water. Set it in sunlight and change the water every 2 days. After 7–10 days, transfer to soil for best results.
What to expect:
New leaves will sprout from the center. Lettuce won’t regrow a full head, but you’ll get tender baby greens.
3. Carrots (Tops Only)
Skill Level: Easy
Time to see growth: 1 week
You won’t regrow full carrots, but you can grow carrot greens, which are edible and flavorful.
How to grow:
Save the top 1 inch of a carrot. Place it cut-side down in a shallow plate with just enough water to touch the bottom. Put it in sunlight. Change the water every 1–2 days.
What to expect:
Feathery carrot tops grow quickly and can be used in: pesto salads sautés chimichurri
4. Potatoes & Sweet Potatoes
Skill Level: Medium
Time to see growth: 1–2 weeks
Potatoes grow from the “eyes” or sprouts on old potatoes.
How to grow:
Choose a potato with eyes or small sprouts. Cut it into chunks (each with at least one eye). Let them dry 24 hours to prevent rotting. Plant 4–6 inches deep in soil or a bucket with drainage.
What to expect:
These plants grow well in containers. The more soil you mound up as they grow, the more potatoes you’ll get.
5. Garlic
Skill Level: Easy
Time to see growth: 7–10 days
Garlic is one of the most satisfying kitchen scraps to regrow.
How to grow:
Plant a single clove pointed side up, 1–2 inches deep in soil. Water lightly. Place in full sun.
What to expect:
The green shoots (garlic scapes) can be harvested for cooking. If given enough time, the clove can grow into a full new bulb.
6. Herbs: Basil, Mint, Cilantro
Skill Level: Easy
Time to see growth: 5–7 days
Regrowing herbs helps you avoid buying new bunches every week.
How to grow:
Trim off leaves from the bottom of the stem. Place stem cuttings in a jar of water. Keep jars in bright, indirect light. After roots form (1–2 inches), transfer to soil.
What to expect:
Many herbs will grow a full new plant with proper watering and sunlight.
Tips for Growing from Scraps Successfully
1. Use Clear Jars or Containers
Seeing the water line helps prevent rotting and reminds you to refresh water.
2. Change Water Frequently
Every 1–3 days prevents bacteria and mold.
3. Use Filtered Water if Possible
Chlorine in tap water can slow growth.
4. Give Them Light — but Not Intense Heat
Most scraps love bright windows, not direct scorching sun.
5. Transfer to Soil When Ready
Growing in water starts the roots, but soil creates long-term plants.
6. Don’t Overcrowd
Give each scrap enough space for airflow and root growth.
