Iowans wishing to become Master Gardener volunteers choose a county to complete training through, participate in online learning modules, and attend at least 4 in-person training sessions organized by the county office. After passing the final exam, trainees put their knowledge to work with a 40-hour internship in their training county. Applicants have from January 15 to February 12 to apply for the spring session.
