About the Master Gardener Program

The DC Master Gardener volunteer training program trains volunteers in sustainable urban gardening practices. Residents who graduate from the program become certified Master Gardeners and go on to volunteer in their communities providing support to a wide range of garden-based projects and activities.

After going through the Basic Training and getting certified, Master Gardener volunteers become representatives of UDC, and work towards building a healthier city in partnership with DC residents.


To train volunteers on effective and sustainable horticultural practices, landscape problem solving, and vegetable and ornamental growing. The priorities of DC residents drive the content. It is DC-centric, urban-based, and most importantly, accessible to residents in all 8 Wards.

The program will be guided by UDC’s Equity Imperative and the sustainability goals of the District of Columbia.

  • Application Process | Participants submit an application form to the Master Gardener Coordinator. Applications are sorted by ward so that there is equal representation from throughout the city, and essays are evaluated by a review committee using a rubric that looks for volunteer interest and a commitment to garden education/urban gardening. The applicant is notified by the Master Gardener Coordinator whether or not they have been selected as a MG Trainee.
  • Trainee | The next stage of the program is 48 hours of basic training. Master Gardener Trainees are taught about a variety of horticultural subjects by specialists, educators, and other horticulture professionals. Once the course has been completed, participants take a Final Exam. If they pass the exam (75%), participants move on to the next phase of the program and are considered Master Gardener Interns.
  • Intern | Once a Master Gardener Trainee has completed the Master Gardener Basic Training and passes the final exam, they become a Master Gardener Intern. Interns must complete at least 40 hours of approved volunteer service over a twelve-month period to achieve the status of Master Gardener.
  • Certified Master Gardener | After completing those golden 40 volunteer hours, participants become Certified Master Gardeners. In order to remain active, Certified Master Gardeners must:
    Provide at least 20 hours of certified volunteer service each calendar year.
    Complete at least 10 hours of continuing education each calendar year.

About the Volunteer Training

The DC Master Gardener Basic Training will give students an overview of sustainable urban gardening theory and practice. The training is divided into two phases: the first is 48 hours of online learning; the second is 40 hours of volunteer experience. The curriculum is focused on sustainable urban gardening concepts and techniques that have practical application to the DC setting.

The first phase of the training will run for 16 weeks. Most classes will be held weekly on Wednesday evenings from 6 to 9 pm, with 4 classes on Saturday mornings from 9:00-12:00. The Wednesday classes will be held online, with recordings made available to participants, and the Saturday classes will be held in person at different garden locations. At the end of the 16 sessions, students will take an exam which they are required to pass with 75% or more in order to go on to the next phase of training.

The next phase of the training is practical and hands-on. The aim is for students to have practical, hands-on experience and develop manual skills. We believe that students will develop a deeper understanding through practice. Students will select a couple of topics they are most interested in and would like to develop a deeper understanding. They will build a plan to volunteer at different projects around the city to gain more knowledge and put their skills into practice. The plan must be submitted to the Master Gardener coordinator and approved before participants begin their volunteer activities.

Once the participants complete their volunteer activities satisfactorily, they become certified Master Gardeners. In order to maintain active status, MG volunteers are required to complete 20 volunteer hours and 10 continuing education hours per calendar year.


Participants will graduate from the DC Master Gardener Basic Training with sufficient skills to volunteer at various garden projects around the district. They will have a good understanding of sustainable urban gardening theory and practice. At the end of the training, students should feel confident in their ability to answer questions from the public about different aspects of gardening. They should also have a deep understanding of a handful of chosen topics and will feel confident in leading activities and delivering short workshops and classes on these subjects.
