You can regrow a celery stalk from the base you normally toss in the trash.
It sounds too good to be true, but this is one of the easiest kitchen scraps to bring back to life.
If you’ve ever wondered how to regrow a celery stalk, you’re in the right place.
All you need is the leftover bottom, a little water, and a sunny windowsill to get started.
In this post, we’ll walk through exactly how to regrow a celery stalk step by step, plus how to move it to soil and keep it growing for months.
Let’s get into it.
How to Regrow a Celery Stalk from the Base
Learning how to regrow a celery stalk starts with saving the right part of the plant.
Here’s the simple process:
1. Save the Base
When you chop your celery, don’t throw away the bottom two inches.
That flat, pale base is where the roots and new leaves will sprout.
Use a sharp knife to cut a clean, straight line about two inches up from the bottom.
The cleaner the cut, the better your chances of regrowing a celery stalk successfully.
2. Place It in Shallow Water
Grab a small bowl or jar and fill it with about an inch of fresh water.
Set the celery base cut-side down in the water.
Make sure the water only covers the bottom of the base, not the whole thing.
Too much water can cause the base to rot before it has a chance to regrow.
3. Find a Sunny Spot
Place your bowl on a bright windowsill where it gets indirect sunlight.
Celery loves light, but harsh midday sun can dry out the tiny new shoots.
A warm spot near a kitchen window is usually perfect for regrowing a celery stalk.
4. Change the Water Every Couple of Days
Fresh water is key when you regrow a celery stalk in water.
Swap it out every two days to keep it clean and oxygenated.
If the water turns cloudy or starts to smell, change it right away.
Rotten water is the number one reason celery bases fail to regrow.
5. Watch for New Growth
Within five to seven days, you’ll notice tiny green leaves emerging from the center.
After about two weeks, small stalks will start to form.
This is the moment you know you’ve successfully regrown a celery stalk from just a scrap.
How Long Does It Take to Regrow a Celery Stalk?
Most people want to know how long it takes to regrow a celery stalk before they even start.
The honest answer is: it depends on the conditions, but usually two to three weeks.
Here’s what affects the timeline when you regrow a celery stalk:
1. Light Levels
More bright, indirect light means faster growth.
A dim corner will slow everything down and your celery stalk may never fully regrow.
2. Water Freshness
Clean water keeps the base healthy and speeds up regrowth.
Stale water invites bacteria, which stalls the process of regrowing a celery stalk.
3. Temperature
Celery prefers cool to moderate temperatures, around 60 to 70°F.
Extreme heat or cold will slow down how fast your celery stalk can regrow.
4. Size of the Base
A thicker base with more nodes regrows faster and stronger.
Thin, tiny bases may still work, but they take longer to regrow into a full celery stalk.
How to Regrow a Celery Stalk in Soil
Once your celery base has roots and a few inches of new growth, you can move it to soil.
This is how to regrow a celery stalk that actually gets thick and crunchy.
Here’s how to do it:
1. Wait for Roots
Don’t rush the transfer.
Wait until you see small white roots forming around the bottom of the base.
This usually happens within one to two weeks of regrowing your celery stalk in water.
2. Pick the Right Potting Mix
Use a rich, well-draining potting mix.
Celery loves moisture, but soggy soil will rot the roots you worked so hard to grow.
A mix with compost works great when you regrow a celery stalk in soil.
3. Plant It Shallow
Set the base into the soil so the crown sits just above the surface.
Burying it too deep can smother the new growth.
Firm the soil gently around the base to help your celery stalk regrow upright.
4. Water Regularly
Keep the soil consistently moist, not soaking wet.
Celery is a thirsty plant, so check the soil every day or two.
Consistent moisture is what helps a celery stalk regrow thick and healthy.
5. Feed It Occasionally
A diluted liquid fertilizer every two weeks gives your plant a boost.
This is especially helpful if you want to regrow a celery stalk that produces multiple harvests.
6. Harvest Outer Stalks First
When stalks reach about six to eight inches, you can start harvesting.
Snip the outer stalks first and leave the center to keep growing.
This way, you can regrow a celery stalk again and again from the same plant.
Common Mistakes When You Regrow a Celery Stalk
Even easy projects go wrong sometimes, so here’s what to avoid.
Skipping water changes is the fastest way to fail at regrowing a celery stalk.
Using tap water that’s heavily chlorinated can also slow things down.
And don’t skip the sunlight, because celery needs light to regrow properly.
So, How Do You Regrow a Celery Stalk?
You regrow a celery stalk by saving the base, placing it in shallow water, and giving it light.
Within a couple of weeks, new leaves and stalks will appear.
Once roots form, move it to soil for a thicker, longer-lasting plant.
Now you know exactly how to regrow a celery stalk from kitchen scraps.
Give it a try this week and you might never buy celery again.
