Herdman delivered potatoes to isolating families and a home for disabled children in addition to placing a large bag of potatoes in North Yorkshire for people to pick up.
"I delivered all day Saturday and all day Sunday, from 8 a.m. to 8 p.m. I have backache, leg ache, had to pick them all by hand," she said. "I was inundated with hundreds of messages from people saying, 'in a world so dark and selfish, you have made us smile.'"
Herdman said she wanted to show the generosity of farmers as stores have faced empty shelves amid the pandemic.
"To me, it's not a big thing, we're just giving away potatoes," she said. "I don't understand selfish people, I've been a giver all my life. Hopefully, it proves that farmers aren't that tight."
North Yorkshire County Council member for the town of Boroughbridge, Robert Windass praised Herdman for her work.
"It is a fantastic and generous thing to do in these very uncertain times," he said. "This helps show there is plenty of food to go around."
