Aloha | E Komo Mai!

Welcome to the Kauaʻi Master Gardener (MG) Program homepage. The Kauaʻi MG Program is a volunteer program administered by the University of Hawaiʻi (UH) College of Agriculture and Human Resources (CTAHR) Cooperative Extension Service (CES). Kauaʻi Master Gardeners are trained volunteers who assist the University in its mission to deliver relevant, research-based, environmentally sound horticulture information to the public. Through community outreach and education, we strive to promote sustainable gardening practices and environmental stewardship on Kauaʻi.

Please look into these programs, active in our community, as sources of local food during this upset:

Also, here is a compiled list of local gardening resources:


Please contact James if you have other resources to share; centralized repositories of resources are preferred.

Training Program

Typically, the MG Training Program is offered once a year over a span of 16-weeks from February to May. The Training is conducted by UH faculty and local experts in botany, plant physiology, soil science, organic agriculture, plant pathology, entomology, native plants and more. Participants receive around 48 hours of classroom training, equivalent to a college-level introductory horticulture course. The program’s core curriculum covers the following topics:

  • Introduction to Gardening in Hawaiʻi
  • Basic Botany & Plant Physiology
  • Plant Propagation & Pruning
  • Soils & Fertilizers
  • Organic Gardening
  • Plant Pathology/Diseases
  • Entomology & Integrated Pest Management
  • Fruits
  • Vegetables
  • Tropical Plants & Lei Flowers
  • Tropical Trees
  • Lawns & Ground Covers
  • Native Plants of Hawaiʻi

Classes are held at the Kauaʻi Agricultural Research Center in Wailua, or via Zoom with hands-on activities. There is a course fee that covers materials and resources used in the course, and it is determined on a yearly basis. Last year it was $200.

Volunteer Service

In the first year after completing the training course, participants are required to fulfill a minimum of 50 hours of volunteer service in order to become certified Master Gardeners. Volunteer opportunities include:

  • Staffing the Plant Question Helpline
  • Developing demonstration gardens
  • Growing plants to sell at garden fairs
  • Writing for the MG newsletter, Facebook page, or local paper
  • Conducting internet or field research
  • Teaching and consulting at school and community gardens
  • Offering lectures and workshops at various venues around Kauaʻi

A minimum of 40 hours of volunteer service and 10 hours of continuing education per year is required in order to maintain active status in the program.


Certified Kauaʻi MGs enjoy many benefits, including the chance to join a community of like-minded people, passionate about gardening and making a difference on Kauaʻi. Other benefits include the opportunity to participate in ongoing membership activities such as the MG Continuing Education Program, monthly meetings, field trips, statewide conferences, free seeds, workshops, social events, and more!
