You can regrow celery indoors from the base of a store-bought bunch, and it’s one of the easiest kitchen projects you’ll ever try.
All you need is a celery stalk bottom, a shallow dish of water, and a sunny windowsill.
Within days, you’ll see fresh green shoots emerging from the center, ready to grow into a whole new plant.
If you’ve been wondering how to regrow celery indoors, the answer is simpler than you think.
In this post, we’ll walk through exactly how to regrow celery indoors step by step, plus tips to keep it thriving.
Let’s dig in.
How to Regrow Celery Indoors: The Basics
Learning how to regrow celery indoors starts with understanding what the plant actually needs.
Celery is a marsh plant by nature, so it loves moisture and cool temperatures.
That’s why the water method works so well for getting it started.
Here’s what you’ll need to regrow celery indoors successfully:
A fresh celery base about two inches tall, a shallow bowl or jar, fresh water, and a spot with indirect sunlight.
The key to how to regrow celery indoors is patience, because the first week is all about roots forming.
Once you master the basics, you can regrow celery indoors again and again from the same grocery haul.
1. Choose a Healthy Celery Base
The best way to regrow celery indoors begins with picking the right starting piece.
Cut the bottom two inches off a fresh bunch of celery and save it.
Look for a base that’s still firm and pale green, not brown or mushy.
A healthy base gives you a much better chance of regrowing celery indoors without issues.
2. Place It in Shallow Water
Set the celery base cut-side down in a shallow dish or glass of water.
Add just enough water to cover the bottom half inch of the base.
You don’t want the whole thing submerged, or it’ll rot instead of grow.
Change the water every day or two to keep it fresh and oxygenated.
This simple step is the heart of how to regrow celery indoors, so don’t skip it.
3. Give It Plenty of Light
Place your dish on a bright windowsill that gets indirect sunlight.
Celery needs light to grow those fresh green stalks, but harsh afternoon sun can scorch it.
A spot that gets four to six hours of gentle light is ideal.
If your window is dim, a small grow light works wonders too.
How Long Does It Take to Regrow Celery Indoors?
How long it takes to regrow celery indoors depends on the conditions you provide.
Most people see tiny roots forming within three to five days.
After about a week, new leaves start pushing up from the center of the base.
In two to three weeks, you’ll have fresh stalks you can actually snip and eat.
If you’re regrowing celery indoors in a colder room, expect things to move a bit slower.
Warmth speeds up growth, so keep your setup away from drafty windows in winter.
1. When to Move It to Soil
Once roots are an inch or two long, you can transplant your celery into potting soil.
Use a pot with drainage holes and a rich, moisture-retaining mix.
Bury the base so just the new shoots sit above the soil line.
Keep the soil consistently damp, but never soggy.
Moving to soil is how to regrow celery indoors for a bigger, stronger harvest.
2. Feeding Your Celery
Celery is a hungry plant and benefits from regular feeding.
Use a balanced liquid fertilizer every couple of weeks.
This keeps the stems crisp and encourages steady growth.
Without nutrients, your celery will grow thin and pale.
3. Common Problems to Watch For
The biggest mistake people make when learning how to regrow celery indoors is letting the water go stale.
Cloudy water breeds bacteria and rot.
Another issue is too much direct sun, which wilts the tender shoots.
Yellowing leaves usually mean the plant needs more light or nutrients.
Fix these small problems early and your celery will keep growing strong.
Tips for Regrowing Celery Indoors Successfully
Here are a few extra tricks to make regrowing celery indoors even easier.
Harvest outer stalks first and let the center keep growing.
Keep the plant away from heating vents, since dry air stresses celery.
Rotate the pot now and then so all sides get light.
And remember, you can regrow celery indoors over and over from the same base for several rounds.
So, Can You Regrow Celery Indoors?
You can regrow celery indoors from a simple store-bought base, and it’s a fun, rewarding project.
All it takes is water, light, and a little patience.

So the next time you chop celery for soup or a snack, don’t toss the base.
Now you know exactly how to regrow celery indoors and enjoy homegrown greens right from your kitchen.
