Growing a massive vegetable isn't just about water and dirt. It’s an obsession. Most people walk into a supermarket and see those uniform, orange sticks packed in plastic bags and think, "Yeah, that’s a carrot." But for a very specific group of competitive gardeners, those are basically toothpicks. When we talk about the longest carrot in the world, we aren't talking about something you can dip in ranch dressing at a party. We are talking about a biological anomaly that looks more like a high-tension power cable than a root vegetable.
It’s huge. It’s spindly. It’s honestly kind of terrifying if you think about the physics involved in pulling it out of the ground without it snapping into a dozen orange pebbles.
The Record That Defies Logic
Joe Atherton is a name you need to know if you care about giant veg. In 2017, at the CANNA UK National Giant Vegetables Championship held at the Malvern Autumn Show, Joe brought a carrot that looked like it belonged in a museum of ancient artifacts. It measured a staggering 6.245 meters. To put that in perspective for you, that is over 20 feet long. That’s longer than a standard shipping container. It’s longer than a giraffe is tall.
Imagine trying to transport that. You can’t exactly toss it in the trunk of a Honda Civic. Joe has been doing this for a long time, and he’s basically a legend in the giant veg community. He didn't just wake up one day and find a 20-foot carrot in his backyard. This was the result of years of trial and error, specific soil mixtures, and a growing setup that looks more like a laboratory than a garden.
The previous record holder was Joe himself, which tells you everything you need to know about the competitive nature of this hobby. He beat his own 2016 record of 5.7 meters. It’s a game of inches—or rather, centimeters—at this level.
How Do You Actually Grow a 20-Foot Root?
You can’t just dig a hole in the ground. If you try to grow a carrot in standard garden soil, it hits a rock or a clump of clay and it forks. It gets stubby. To get the longest carrot in the world, you have to cheat the environment.

Gardeners like Joe use long plastic pipes. They stand these pipes up vertically, sometimes reaching high into the air or angled across a specialized frame. They fill these tubes with a very specific, sieved compost mixture. There can’t be a single pebble. Not one. The soil has to be so fine that the taproot feels zero resistance as it pushes downward.
Think of it like this: the carrot is "racing" to the bottom of the tube.
- The Tube: Usually PVC or industrial piping.
- The Mix: A blend of peat, sand, and fertilizers that provide enough nutrients without being so "hot" that they burn the delicate tip.
- Watering: This is the tricky part. You have to keep the moisture consistent all the way down. If the bottom is dry, the root stops. If the top is too wet, it rots.
It’s a balancing act. Honestly, it’s a miracle they don't break more often. When it comes time to harvest, they don't just pull. They have to lay the pipes down and carefully wash the soil away with a hose, inch by inch, to reveal the root without snapping it. If it breaks, the record is gone. No glue allowed.
The Difference Between Long and Heavy
There is a massive distinction in the world of competitive gardening between "long" and "heavy." They are two completely different sports.
If you want the heaviest carrot, you’re looking for girth. The current record for the heaviest carrot is held by Christopher Qualley from Minnesota. His carrot weighed about 22.44 pounds (10.17 kg). It looked like a gnarled, orange meteor. It’s a dense, mutated-looking thing that has multiple "fingers" or roots clumped together.

The longest carrot in the world, however, is all about that single, wandering taproot. It’s thin. It’s wispy at the end. It wouldn't win a beauty contest, and it certainly wouldn't be good in a stew. By the time a carrot gets that long, it’s incredibly woody and fibrous. You’d need a literal chainsaw to eat it, and it would probably taste like a damp cardboard box.
Why Do People Do This?
It’s easy to look at a 20-foot carrot and ask, "Why?"
But why do people climb Everest? Why do people restore old cars? It’s about the challenge of pushing a species to its absolute limit. Carrots weren't "meant" to be 20 feet long. Evolution designed them to store enough energy to survive a winter and then go to seed. By manipulating the environment, these gardeners are basically hacking the plant's DNA.
There’s also a massive community aspect. The Malvern Autumn Show or the Harrogate Flower Show aren't just events; they’re battlegrounds. There is a lot of "trash talk," though it’s usually polite British trash talk about nitrogen levels and pH balances. They share secrets, but only up to a point. Everyone wants that Guinness World Record certificate on their wall.
Common Misconceptions About Giant Carrots
- "They must be full of chemicals." Actually, most giant veg growers rely heavily on organic matter and very precise nutrient timing. If you over-fertilize, the carrot splits. It’s more about the physical structure of the soil than just dumping chemicals on it.
- "You can eat the leftovers." You really can’t. As mentioned, the texture is awful. These are grown for the scale, not the palate.
- "It's just luck." Luck plays a part—you need a seed with good genetics—but 99% of it is the engineering of the growing tube.
Is the Record Likely to be Broken Soon?
The jump from 5 meters to over 6 meters was huge. We are reaching a point where the sheer logistics of the growing tubes make it difficult to go much further. Imagine needing a 30-foot pipe. How do you mount that? How do you harvest it?

However, as long as people like Joe Atherton are around, the longest carrot in the world record is never truly safe. New hybrids are being developed specifically for length, and the "pipe technology" is getting more sophisticated. We might see a 7-meter carrot by the end of the decade.
Practical Steps for the Aspiring Giant Gardener
If you’re sitting there thinking you want to try this, don't start with a 20-foot pipe. You’ll just frustrate yourself.
- Get the right seeds: You can't use standard "Nantes" or "Chantenay" seeds from the hardware store. Look for "St. Valery" or specialized "Long Root" varieties from competitive seed suppliers.
- Build a "Station": Start with a 4-foot PVC pipe. Cut it in half lengthwise and tape it back together so it’s easier to open during harvest.
- Sieve everything: Your soil needs to be like powdered sugar. If you find a lump the size of a pea, get rid of it.
- Consistency is king: Use a timer for your watering. Any stress to the plant will cause it to stop focusing on that downward root growth.
Ultimately, growing the longest carrot in the world is a lesson in patience. You spend months tending to a plant you can't even see, hoping that deep inside that plastic tube, a tiny orange root is making its way toward history. It’s a hidden masterpiece that only sees the light of day for a few minutes on a judging table before it shrivels up. But for that one moment, it’s the greatest carrot on the planet.
To start your own journey, focus on soil aeration first. Compaction is the enemy of length. Even if you only grow a two-footer, you'll have a better understanding of the incredible feat Joe Atherton pulled off back in 2017.
