Trowel & Error Farm is an Iowa City based vegetable farm with an experimental approach to farming. We grow over 50 different kinds of vegetables with a focus on crops that are harder to find in our area, including specialty greens like watercress, Chinese cabbage, broccoli raab, radicchio, endive, and more.
Grounded in the belief that growing practices matter just as much as the food we distribute, we are dedicated to growing organically (although we aren’t certified) and using regenerative agricultural practices.
We believe that food is a human right, and far too often people in our community are priced out of fresh produce. We accept SNAP and Double Up Food Bucks, offer reduced rates for our CSA, and work with Table to Table to glean extra produce from the farm for donation to local food pantries and other access sites.
We rent the two acres we farm on from Johnson County through the Land Access Program at the Johnson County Historic Poor Farm.
About the Farmer

Carly McAndrews (she/her) was inspired to start farming in 2011 after attending a panel of women farmers for an environmental studies course at the University of Vermont. After working on her first vegetable farm that season, she was hooked and continued working on different farms in Connecticut, Vermont, and Iowa, eventually meeting Bryant Mann in 2017 when they both worked at Echollective Farm in Mechanicsville, IA. In 2019, Carly achieved a Masters degree in Sustainable Agriculture from Iowa State University, and that Spring she and Bryant started Trowel & Error Farm together. Now a solo operator, Carly is grateful for Bryant’s continued support, which comes in the form of lending his truck, helping out with big projects, offering an empathetic ear, and being the best friend a person could have. Carly is most inspired by vegetable production that extends the season early in the spring and into winter, and some of her favorite vegetables to grow include leeks, carrots, and chicories.
