Brussels sprouts fans are facing a shortage after what farmers are calling the “worst autumn in living memory”.

Christmas dinners could be under threat as farmers are struggling to harvest enough of the festive staple, along with other veg such as carrots, parsnips, swedes and potatoes.

Farmers have been struggling to harvest and plant their autumn crops as fields have been inundated with floodwater.

Meanwhile, billions of slugs attracted to the soggy ground have been munching their way through the rest of the yield – which for winter cereals is only around half of what it should be.

The National Farmers’ Union says wet weather conditions have had a “significant” impact on farmers and prices could be pushed up if there are shortages.

The flooding in recent times means that up to 50% of crops in the UK could be compromised

NFU crops chief Tom Bradshaw said: “For many farmers it is the worst autumn in memory.

“Even when they have managed to plant crops, the yields will be severely compromised.

“We estimate that about 40 to 50% of the winter cereal crop has been planted across the UK, with a similar situation in East Anglia.”

Deputy president Guy Smith said: “A dry run up to Christmas or a kind spring will allow farmers to get the growing year back on track to a certain extent.

“However, cropping programmes are severely disrupted and the 2020 harvest is already compromised.”
