Volunteer Commitment

Once you are accepted as a MGiT, you will begin your volunteer commitment and begin to record your volunteer hours. All MGiT and Master Gardeners are required to provide a minimum of 30 hours of combined advice hours and administrative or education hours each year.

Once you have completed both the educational (within 3 years) and volunteer requirements for two years, you are officially a Master Gardener!
