1. 🧅 Green Onions
The easiest vegetable to regrow in a jar of water.
Green onions are practically foolproof. After using the green tops in your recipes, save the white bulbs with roots attached.
How to regrow:
- Place the root ends upright in a glass of water.
- Set on a sunny windowsill.
- Change the water every 2–3 days.
🌿 You’ll see green shoots within a few days—and they’re ready to snip and eat within a week!
2. 🥬 Romaine Lettuce
Don’t toss that core—regrow fresh salad leaves instead.
The dense base of a romaine head still holds life, even after you’ve used the outer leaves.
How to regrow:
- Cut the base (2–3 inches from the bottom).
- Place it in a shallow dish with ½ inch of water.
- Put it near sunlight and mist the top occasionally.
🥗 In 7–10 days, new leaves will start to emerge. You can harvest baby greens, or replant in soil for full heads.
3. 🌿 Celery
Another easy windowsill regrower that gives you crunchy stalks and fresh leaves.
Celery follows the same principle as romaine, growing from its bottom stump.
How to regrow:
- Slice 2 inches from the base.
- Place in a shallow bowl with water (cut side up).
- Put in a sunny spot and change water every other day.
🌞 New stalks and leafy growth will emerge in about a week. For longer growth, transfer to soil once roots appear.
4. 🧄 Garlic
Plant a clove, get a bulb—or use the greens like scallions.
You can regrow garlic for full bulbs (takes several months) or harvest the green shoots for a mild garlic flavor.
How to regrow:
- Take a large garlic clove (pointed end up) and plant it in moist soil.
- Place in sunlight and water lightly.
- Shoots appear in days; bulbs mature in a few months.
🧪 Don’t toss sprouted garlic—it’s perfect for replanting and reproducing.
5. 🧄 Leeks
Regrow this allium just like green onions—for soup bases and stir-fries.
Leeks are another veggie that loves water propagation.
How to regrow:
- Save the bottom 2 inches of your leek (with roots).
- Set it upright in a glass with just enough water to cover the roots.
- Place in a sunny window and change the water every few days.
🌱 Harvest the new green growth when it’s a few inches tall. Repeat as needed.
6. 🌿 Basil
Propagate an endless basil patch with just one stem.
Fresh basil doesn’t need seeds to grow again. It can root quickly in water and thrive in soil.
How to regrow:
- Take a healthy 4-inch basil stem and strip the lower leaves.
- Place in a jar with water and leave in sunlight.
- In 7–10 days, roots will sprout.
🌿 Once rooted, transplant to soil and enjoy continuous harvests all summer long.
7. 🥔 Potatoes
Turn your old sprouting potatoes into a new harvest.
Those “eyes” growing on a potato? They’re ready to become a new plant.
How to regrow:
- Cut the potato into chunks, making sure each piece has at least one eye.
- Let cut pieces dry for a day to avoid rotting.
- Plant in deep soil or a container with room to spread.
🥔 With sunlight, water, and time, each chunk will produce a brand new potato plant.
