The Olson Garden Market is located four miles west of Grinnell on Highway T38N. You will find us at Grinnell Farmers Markets on Thursdays and Saturdays selling fresh seasonal produce. We are also open select times at the farm. We grow a wide variety of produce ranging from asparagus, summer squash, zucchini, tomatoes, carrots, beets, raddish, onions, kohlrabi,cabbage, potatoes, beans, and herbs. You name it, we likely grow it. Olson Garden Market is not just about great produce we provide, but the helpful tips and friendly smiles that we bring along the way.
