Do you enjoy gardening, learning about plants, and helping others succeed in their landscapes and gardens? The UConn Extension Master Gardener Program is now welcoming applications for the 2027 training class, offering Connecticut residents the opportunity to deepen their horticultural knowledge while making a positive impact in their communities.

For more than four decades, the UConn Extension Master Gardener Program has connected enthusiastic gardeners with research-based education and meaningful volunteer opportunities. Participants receive comprehensive training from UConn Extension experts and become trusted sources of gardening information in communities throughout Connecticut.

What is a Master Gardener?

UConn Extension Master Gardeners are trained volunteers who share university-based horticultural information with the public. They help residents answer questions about plants, soils, insects, diseases, invasive species, sustainable gardening practices, and more. Through educational outreach, plant clinics, demonstration gardens, community events, and other volunteer efforts, Master Gardeners help connect Connecticut residents with reliable gardening information.

What You’ll Learn

The Master Gardener certification program provides a strong foundation in horticultural science and practical gardening skills. Training includes topics such as:

• Botany and plant growth
• Soils and soil health
• Plant pathology
• Entomology
• Integrated Pest Management (IPM)
• Trees, shrubs, and ornamental plants
• Vegetable and fruit production
• Turfgrass management
• Invasive plants and weeds
• Water quality and environmental stewardship
• Plant identification and diagnostics

The program begins each January and includes sixteen weeks of intensive instruction led by UConn Extension educators and specialists. Participants gain the knowledge and confidence needed to answer gardening questions and provide science-based recommendations.

Learning Through Volunteer Service

Becoming a Certified UConn Master Gardener involves more than classroom learning. Participants also complete a 60-hour internship that combines hands-on training with community outreach. Volunteers learn how to research horticultural questions, assist the public, and support educational programs that benefit Connecticut communities.

Volunteer experiences may include:

• Assisting with plant and garden clinics
• Staffing educational exhibits at fairs and public events
• Working in demonstration gardens
• Presenting educational programs
• Supporting community gardening initiatives

Why Become a Master Gardener?

Many participants join the program to improve their own gardening skills, but they often discover additional benefits along the way. The program provides opportunities to:

• Learn from UConn Extension experts
• Connect with fellow gardening enthusiasts
• Support environmental stewardship efforts
• Give back to local communities
• Continue learning through advanced training opportunities after certification

Is the 2027 Program Right for You?

Whether you are an experienced gardener or simply eager to expand your understanding of plants and landscapes, the program offers a rewarding opportunity for personal growth and community service.

The 2027 class will begin in January, and interested applicants are encouraged to learn more about program requirements, training expectations, and the application process.

On a weekday morning at the Mark Twain House and Museum in Hartford, the parking lot tells its own story. Cars arrive from Pennsylvania, Virginia, New York, Vermont, and Indiana; the visitors are drawn to the iconic home, and increasingly to the gardens surrounding it. Winding through historic beds, pollinator pathways, urns, and terraces surrounding the home, they encounter living history stewarded by UConn Extension Master Gardener volunteers.

For more than a decade, Master Gardener volunteers have played a vital role in shaping, restoring, and sustaining the historic gardens at the Mark Twain House. Their work blends horticultural expertise with research, interpretation, and care, helping ensure these landscapes reflect the Victorian-era setting of Twain’s time while remaining resilient and relevant today.

Unlike the UConn Extension Master Gardener Program, the Fundamentals of Home Gardening course does not have a volunteer component. It is a fully online, self-paced program designed for individuals who want to deepen their gardening knowledge without the commitment of volunteer service. “Gardening is not just about planting; it’s about understanding the science behind it,” said Bonnie Burr, assistant director for UConn Extension. “This course gives participants the foundation they need to create and maintain healthy, productive gardens.”

Benefits of Gardening Participants in this course will not only gain practical gardening skills but also experience the many benefits gardening provides:

• Health & Well-being: Gardening is a great form of physical activity, reduces stress, and improves mental well-being.

“The program provides the opportunity for beginner, intermediate or experienced gardeners to increase their personal knowledge of the practice of gardening … The program allows you to meet with like-minded people over a common interest – growing plants,” says Advanced Master Gardener Ken Sherrick of Middletown.

UConn Extension Master Gardeners have an interest in plants, gardening, people and the environment.  Specifically, they are willing to share their knowledge, passion and enthusiasm with their communities, providing research-based information to homeowners, students, gardening communities and others. They receive horticultural training from UConn, and then share that knowledge with the public through community volunteering and educational outreach efforts. UConn Extension Master Gardeners help with community and museum gardens, school gardens, backyard projects, houseplant questions and more.

Classes begin the week of January 13, 2025. Subject matter includes basic botany, plant pathology, soils, entomology and other aspects of gardening such as plant categories, native plants, and pest management. After the classroom portion, students complete 60 hours of outreach experience during the summer, along with a plant identification project.

“The Master Gardener program gave me an understanding the role of plants and insects within the ecosystem, which fostered a passion for removing invasive plants,” says Advanced Master Gardener Karen Berger of Canton, who now volunteers on a project to remove invasives, replacing them with native plants that benefit the local environment.
