Learning how to regrow celery from the stalk is one of my favorite hacks to reduce food waste. Not only am I making better use of something that I would have otherwise composted (or threw in the stock pot), but I’m literally making more food by just adding water!
This tutorial will teach you how to grow celery from the stalk/stump/base of the bunch of celery you’ve purchased at the store.
This method works as long as you have the root end of an entire bunch of celery. Note that technically a “stalk” of celery is considered the entire bunch of celery, but a stalk is often referred to as a single piece of celery, so I don’t want you to be confused.
I don’t think it will work with an individual stalk (AKA rib) of celery, only the end of an entire bunch.
By regrowing the celery you got from the grocery store, you can essentially save 50% or more off of your purchases of it! You should be able to get at least a few stalks worth of celery out of the stump, if not more!
Depending on how to regrow it, you might get fresh celery growing for months from that single bunch from the grocery store!

How to grow celery in water
Regrowing celery in water is a very simple process that will provide you with fresh food in a couple weeks!
I love teaching people how to grow celery from scraps in water because it’s literally free food! You are getting more celery for your money compared to if you just composted the ends.
You’ll start to see new green growth appearing within a day or so. The process is very easy!
Here are the steps on how to regrow celery in water:
Time needed: 14 days.
Easily learn how to grow celery indoors with only water! There should be enough to eat after a couple weeks.
• Whole bunch of celery (not a single stalk or “rib”)
• Clear bowl or jar (wide enough for the whole base of the celery to fit in and sit flat)
• Fresh water
• Sunny windowsill
- Cut the celery
Cut the entire bunch of celery so there is at least 1″ (2.5cm) left at the root end.
- Put the celery stump in water
Set the stump of the celery in a bowl or jar, root end down. Add enough water to cover the end, but do no fully submerge the whole cutting. Half way is good.
Check the water level every few days. Add more water if the water level drops to make sure it doesn’t dry out. Change the water completely about once a week to keep it fresh.
- Give it light
Place the jar in a sunny windowsill, or underneath an indoor grow light. This one is perfect as it looks like a regular LED bulb, uses very little electricity and fits in regular sockets!
After there is at least a few inches of new growth, you can start harvesting. Just cut the new growth off, taking as much or as little as you need.
Note: the new growth is likely to be mostly leaves for a while. Wait longer to see the stalk growing.
- Plant in soil (optional)
If you wish, you can plant the celery in soil as soon as roots appear. The soil will provide nutrients to the celery plant and help it continue to produce for longer than using just water alone.
FAQ & Troubleshooting
Harvest your celery after they have at least a few inches of new growth on them. It’s best to wait a few weeks to allow the new growth to mature into stalks, rather than just the leafy growth you’ll see at first.
Cut the stalk back to the base with clean scissors or a knife.
Ideally you’ll wait until several ribs have grown out of the stump, then you’ll cut one off and leave the others. Try not to harvest more than 50% of the new growth at a time.
With proper care you should be able to regrow celery for several months in just water.
After a while, you’ll notice it slowing down and eventually will stop regrowing. That’s because it has run out of nutrients!
If you want to keep them growing, plant the green onions in a pot in your windowsill or outdoors (weather permitting). With proper care in soil, celery will grow much longer.
If you don’t have soil to grow them in, just harvest all the growth after it stops producing, then start the process over again with a fresh bunch from the store!
This might happen when you try to grow celery in water.
Plants need water, air, sunlight and nutrients to grow. When you grow celery in water, it has water, air, sunlight, and a small reserve of nutrients in the cutting. Those nutrients will eventually run out and the celery will stop growing.
When this happens, you have 2 options:
1. Plant the cuttings in soil
2. Use up the celery and restart the process with a fresh bunch of celery from the store.
Technically you could also grow celery hydroponically which involves adding the nutrients directly to the water, but that is a lot more technical and not accessible to most people.
If the roots of the celery growing in water become slimy, it’s a sign you need to change the water more frequently.
To fix it, pour out all the water from the jar, rinse the roots under fresh water, then place it back in a clean jar with fresh water, or plant it in soil.
Without any sunlight at all, the celery may grow a couple inches in water, but won’t grow much. If you have even just a bit of sunlight, regrowing celery in water should work, although the growth will likely be much slower than if you had enough sunlight.
You could also use a grow light for indoor plants. I recommend this one.
You really have nothing to lose in trying it, since the ends would have been scraps anyways!
If you don’t have any natural light in your home, keep the celery bunch standing in water in the fridge to make sure it lasts as long as possible and you don’t waste any. It should stay crisp and keep several weeks this way without going limp before you use it all.
Do not expect to regrow an entire bunch of celery, but instead, expect a few small stalks and leaves.
If you plant it in soil with the right conditions after the roots have grown, you can expect more growth and probably get a small bunch of celery out of it.
Yes you can regrow celery from the grocery store, as long as you have the whole bunch of celery, not individual ribs. You will regrow a small amount of new celery from the bunch you bought at the store. Don’t expect a whole new bunch to grow.
I hope this tutorial helped you understand how to regrow celery from scraps easily, even without a garden!
I’d love to hear from you. Did you have success growing celery in water? How do YOU regrow celery? Do you regrow any other food from scraps?? Let me know in the comments!
