The Viral Trick and Whether It Works
If you have seen the videos showing a cut celery base sitting in a shallow bowl of water and sprouting fresh green growth from the centre, you might have wondered whether it actually works or is just a social media trick. The short answer is yes, it genuinely works — the base of a celery bunch contains a living growing point (the apical meristem), and if you give it water, that growing point will resume activity and push up new leaves and thin stalks. It is one of the more reliable kitchen-scrap regrowing experiments you can do.
The longer answer, which the viral videos often gloss over, is that what you get is not the same as the bunch of celery you started with. Regrown celery in water produces thin, leafy growth rather than the thick, crunchy stalks you buy. To get anything approaching a proper stalk, you have to move the base into soil. Understanding why explains both the appeal and the limits of the trick.
How the Regrowth Actually Happens
A celery bunch is a cluster of stalks all growing from a single basal plate — the flat, slightly rounded disc at the bottom where the roots were cut off. Buried in that basal plate, just below the surface, is the apical meristem: the cluster of actively dividing cells that was driving the plant's growth when it was in the field. When you cut the stalks off about 5cm above the base, that meristem is still alive and dormant, waiting for the right conditions to resume growing.
Put the base in a shallow dish of water, cut side up, with the water just touching the bottom, and within a few days you will see small green shoots emerging from the centre. Leaves unfurl first, followed by thin, hollow stalks. The base is using the carbohydrates and water stored in its own tissue to fuel this growth, which is why it works even without soil. Roots will also start to emerge from the bottom of the base after about a week.
This is the same kind of regrowth you can get from other kitchen scraps. The principle is the same as in our guide to regrowing vegetables from scraps — you are relying on a surviving meristem that still has the blueprint and the energy to produce new tissue.
Why You Will Not Get Supermarket Stalks in Water
The growth you get in water is leafy and thin because celery stalks are mostly water held under pressure in pressurised cells — the turgor that makes them snap when fresh. To build those thick, water-filled stalks, the plant needs a steady supply of nutrients, especially nitrogen and potassium, and plenty of light to photosynthesise. Water alone does not provide the nutrients, so the plant cannot lay down the dense tissue that makes a thick stalk.
What you get in water is essentially celery greens — tender, flavourful leaves and thin stalks that are perfectly good to use as a garnish or in a salad or soup. They taste like celery and are arguably more intensely flavoured than the store-bought stalks. But if you want chunky stalks for ants-on-a-log or dipping, you need to move the base into soil.
The Better Method: From Water to Soil
To grow something closer to a usable celery plant, let the base root in water for about a week, then plant it in a pot of good-quality potting mix or in the garden, with the basal plate just below the soil surface and the new shoots above. Keep it well watered and in a spot with plenty of sun. Once in soil, the plant can take up nutrients and will produce thicker, more substantial stalks over the following weeks.
Even in soil, do not expect the celery to match a commercially grown bunch. Commercial celery is grown over several months from seed in carefully managed, nutrient-rich, consistently watered fields, and it is blanched (kept in the dark) to keep the stalks pale and tender. A kitchen regrown plant is starting from a tired basal plate with limited stored energy, so the stalks will be smaller, greener, and more strongly flavoured. It is a fun and useful project, but it is not a free replacement for buying celery.
The best use for regrown celery is as a continuous supply of celery leaves and thin stalks for flavouring stocks, soups, and salads. Snip what you need as it grows, and the plant will keep producing for several weeks.
Is It Worth Doing?
It depends on what you want from it. As a fun experiment, especially with kids, it is genuinely satisfying — you get visible results in days, and it teaches how plants grow from meristems. As a way to reduce food waste, it has some value, since you are using a part of the vegetable you would otherwise throw away (though the base is usually composted anyway). As a way to produce a meaningful amount of food, it is marginal — you will not feed a family on regrown celery.

The Bottom Line
Regrowing celery from the base in water really works — the basal plate has a living growing point that will push up new leaves and thin stalks within days. But the viral trick oversells the result. You get celery greens, not thick stalks. For anything closer to a real stalk, move the rooted base into soil and manage it as a plant. It is a fun, low-effort experiment, and the regrown greens are genuinely tasty, just do not expect it to replace the bunch you buy.
