Jefferson County Colorado Master Gardener Program
Colorado Master Gardener Applications have closed for the 2025 year.
Please review the required dates of the Jefferson County program as you consider applying.
An apprentice year is a commitment of time, and is full of opportunity to learn the program, projects and community. Our staff, volunteers, and apprentice mentors are here to support you! We are excited for your interest and are available to answer questions at cmg_admin@jeffco.us.
Additional information on the Colorado Master Gardener (CMG) program is available at the State Master Gardener Program webpage. If you are interested in learning more about gardening without committing to the volunteer portion of the program, you can still follow the Green School curriculum led from October through March by CSU horticultural professionals.
