Chris Qualley, 34, has been growing giant veg for the past two years at his home in Minnesota.
The previous Guinness world record for the heaviest carrot was 20 pounds, set in 2014 by Peter Glazebrook from Newark, Nottinghamshire.
But Chris was determined to go one step further and has now grown the world's heaviest carrot - with the root veg weighing an impressive 22.4lbs.
And, it's not only carrots that Chris specializes in, he is also growing a giant watermelon, swedes, tomatoes and a pumpkin.
Green-fingered Chris credits his growing success to soil, seeds and lots of high-powered fertilizer.
The weather this summer was also somewhat cool and cloudy - perfect growing conditions for a carrot.
