Master Gardener Training

The Ohio State University Extension offices in Jefferson and Harrison Counties are currently accepting new applications for the 2022 Master Gardener Volunteer training program. Master Gardener Volunteers in Ohio contributed over 180,000 hours of service per year and offer assistance with home horticultural questions, pest identification, school programs, demonstrations, research, and continuing education programs. Participants interested in receiving the 50 hour intensive training will learn about basic botany, plant physiology, soils, entomology, plant pathology, plant diagnostics, integrated pest management, pesticide use and safety, lawn care, home vegetable and fruit production, backyard wildlife management and much more! Working with county Ohio State Extension personnel, Master Gardener Volunteers provide educational services to their communities. If you are a garden enthusiast, this is a great opportunity to share your gardening know-how and skills with others in your community. Cost of the program is $100 for those interested in the program.

**The 2023 Master Gardener Volunteer training this year will consist of both online modules, hands-on labs and tours, and either a writing or presentation project. Participants will be expected to attend orientation and a minimum of 5 labs but can pick and choose either by topic or date that best fits into your schedule. See below for the 2023 lab schedule:
