The couple said on Facebook: "We have always been proud of being both a working organic dairy farm, whilst opening our farm up with our visitor attraction on site.
"COVID-19 has had an impact on everyones lives, and during the last 12 months it has given us the chance to reflect and take stock of what we are trying to manage as a family.
"Therefore we have made the incredibly difficult decision that we will not be reopening.
"We would like to thank everyone who has supported us since we opened in 2007, we have always been blown away by your loyalty.
"We would also like to say a special thank you to our team, both past and present, who have been on this journey with us for the past 13 plus years, you are simply amazing."
