SHAFER, Minn. — Andrew Hanson-Pierre was only back at the farm for a brief spell after his morning gig as a fill-in school bus driver when Margaret, his wife and fellow farmer, had to leave for her own off-season work as a substitute teacher.
They shared a quick hug before Margaret headed to Chisago Lakes Elementary on that morning in early December, leaving Andrew to contemplate how to keep busy all day on their vegetable farm just west of the St. Croix River.
Minnesota's annual plunge into the deep freeze forces farmers to leave fields fallow for the better part of half a year. It's when non-farmers start to wonder: What do you do all winter?
"I get asked that question all the time," said Matthew Fitzgerald, a grain farmer near Hutchinson.
The four seasons dictate the farmer's workflow more than most professions. As winter arrives in Minnesota, farmers shift gears to focus on their business dealings — and maybe even to take some much needed respite.
"I'll read. Go for a hike later," Andrew Hanson-Pierre said, standing under a dim winter sun as wind swept over Clover Bee Farm. "Yesterday I baked bread. There's not a lot of time to cook in the summer. There's some clearing to do in the yard. And we're renovating the farmhouse, which has been sort of never-ending."

A farm is a small business, Fitzgerald likes to remind people. The four winter months when he's not planting, cultivating, harvesting and transporting crops is when he can concentrate on front-office demands. That means planning, marketing, lining up buyers, tax preparation and finances, networking with other farmers and learning the latest in ag techniques and technology.
"By the end of the growing season, I'm tired of being in a tractor and my body's shot," Fitzgerald said. "By the end of winter, I'm tired of looking at a screen and filling out Excel spreadsheets."
