AJ TaylorMarch 7, 2021Last Updated: March 4, 2021 The application window is opening for this year’s Master Gardener training, which will be offered 100% online in the fall. A total of 17 educational modules will be offered by Iowa State University Extension and Outreach, on topics that include houseplants, pollinators, vegetables and perennial flowers. Each course module includes a book chapter, lecture video, online discussion board and a quiz. “We have set up the course so that participants can work through the book chapters and online materials at their own pace, on their own time,” said Susan DeBlieck, Master Gardener program coordinator with ISU Extension and Outreach. “Participants will connect on online discussion forums to share ideas about how they plan to volunteer and what they are learning about plants.”
