Become a URI Master Gardener volunteer!

The URI Master Gardener Program is focused on strengthening local food systems and sharing information amongst community members to help people grow their own food. In 2023, URI Master Gardener volunteers donated 209,134 pounds of fresh produce to hunger relief agencies through donation gardens and on farm food recovery efforts (gleaning). Read more about our impact here. Graduates of the URI Master Gardener Core Training serve as grassroots educators, bringing their newfound knowledge to the community through service projects. URI Master Gardener volunteers have a positive impact locally, while continuing to learn through unique classes and field experiences. In-person and virtual volunteer opportunities are available.

After taking this class, I feel like my knowledge and skills are starting to match my passion and that’s empowering.

How to get Certified

How do I become a URI Master Gardener volunteer?

The road to becoming a URI Master Gardener begins with the core training, is followed by an internship, and continues longterm with continuing education and service. See the steps below for more information.

Step 1: Complete the core training course

The URI Master Gardener Program core training explores the science behind environmentally-sound gardening while honoring ancestral practices. Each class is taught by a different URI faculty, Extension staff member, or community subject matter expert.  The course is designed to be flexible for adult learners with busy lives.   Each participant receives access to an online class website and a Master Gardener mentor to guide you through the first year.  Pre-recorded lectures may be watched at your own convenience. Live webinars allow you to participate in engaging activities, interact with your classmates and instructors, and discover the practical application of course material.  By the end of the semester, you’ll be connected to a wide range of garden service projects that benefit the community.

The course runs from late January to the end of April and live webinars are held one evening per week from 6-7:30 pm.  Full course details are sent out upon acceptance. Learners from all walks of life with an interest in helping Rhode Islanders grow are encouraged to fill out the form ! Financial awards are available through a simple process embedded within the course application.

Step 2: Complete the volunteer internship

Upon successful completion of the core training, trainees become “Interns” and are required to complete 50 hours of volunteer service on an approved project to earn the title of certified “URI Extension Master Gardener”. This place-based, on-the-job training allows participants to extend their learning by working in teams with other volunteers at project sites throughout Rhode Island. Interns have at least two years to complete their internship hours. 

Step 3: Continue learning through our continuing education classes

Certified URI Extension Master Gardeners continue their process of lifelong learning through specially curated continuing education offerings. This includes online classes and in-person field experiences on sustainable gardening and inclusive community engagement. Dig into a topic of interest and build skills to bring back to your garden and community.

The initiatives detailed here, begun proactively in 2020, show the strides we’ve made toward these goals. 

10. I have participated in the Master Gardener Program in another state and would like to transfer to Rhode Island. What is the transfer process?

We encourage and welcome Master Gardeners certified in other states to participate in the URIMGP. To transfer affiliation from another state to the URIMGP, the following documentation should be provided to the State Program Leader (vventurini@uri.edu):

  1. Letter of recommendation from Extension staff at institution where initial certification was earned
  2. Evidence of participation in horticultural service activities/projects as a certified Master Gardener.

The above documentation will be reviewed by the State Program Leader; and one of the following recommendations will be made:

  1. If the transfer Master Gardener is current with their continuing education and service requirements or has participated in a Master Gardener Program in the past ten years, they may be asked to audit select core training classes as determined by the URI State Program Leader; or
  2. If the transfer Master Gardener has not fulfilled their continuing education or service requirements for over 10 years, they will be asked to complete the full URIMGP core training and pay a reduced (50%) registration fee.
