Become a Master Gardener

The Master Gardener program is a volunteer program of the University of Missouri Extension that requires training. Core training is the first step to become a Master Gardener. In addition to completing the Core Training, you will be asked to volunteer 20 hours in the demonstration gardens, which are on-site at the extension center, and 10 hours on other projects.

You can begin volunteering after Class 1 of the training, which is an orientation. When you complete your 30 hour volunteer commitment, you will be recognized as a Master Gardener with a certificate and Master Gardener name badge. You have one year from the completion of training to complete your initial volunteer commitment. In each subsequent year, you must give 20 volunteer hours and six continuing education hours to maintain your status as a Master Gardener. There are a variety of opportunities to complete the requirements each year.

Core Training is offered annually and meets weekly for fifteen weeks. It is important for you to attend all of the classes. The training and volunteer requirement is a substantial time commitment, both in and out of class. Please be sure this volunteer activity fits your schedule. If in doubt, you can always apply in future years.
