One of Queensland's largest carrot growers will open the farm gate next month and let the public help chop down its oversupply problem.

The national carrot market is flooded due a range of factors, including trading restrictions.

Alice Gorman from Kalfresh Vegetables, south-west of Brisbane, said optimum growing conditions this season had also resulted in large crop yields.

"We're facing a problem that we haven't faced in the past 23 years.

"What we think is happening is that Russia has banned European imports, so then those growers are trying to sell carrots into export markets we may serve.

"Also Western Australia ... [is] now selling to the east coast.

"As Queensland growers, we're in a bind."

Growers said they needed to dispose of the carrots but also wanted to prevent waste.

There is a glut of carrots currently on the east coast.

"Some of the early crops that haven't had too much money spent on them will be ploughed into the ground," Ms Gorman told ABC Radio Brisbane's Steve Austin.

"Yet we've put a lot of time and energy in the carrots and we don't want to waste good food so we're inviting families to pick their own carrots.

We're calling it our carrot-astrophy day."

Buy local, help farmers

Ms Gorman urged Queenslanders to look out for locally grown carrots when shopping.

"We're expecting at a retail level that the carrots will be sold for $1 or $2 a kilo," she said.

"What we're asking people is to choose Queensland carrots as they have low food miles and are sweet and delicious.

"We're trying to get something positive out of this and we think by showing people what we do we can turn a negative into a positive."

She said the impact of the glut on farmers had been more than monetary.

"One farmer said to me it's not the money loss, it's the loss of effort and that's hard to mentally and emotionally deal with.

"If the farmers can see that the carrots aren't going to waste then a positive comes from it."

Chefs to do their bit

Ms Gorman said farmers hoped to also reach out to leading Brisbane chefs to help.

"We're talking to them about how they can hero the carrot this month by putting it more on the menu," she said.

"We do all we can with carrots including carrot cake, carrot sausages, carrot beer and carrot vodka to use the excess."

The farm will be open to the public to pick excess carrots on October 7. More details can be found through Kalfresh.
