Located on the island of O’ahu with administrative offices at the University of Hawaii, Manoa, the O’ahu Master Gardener program operates out of the UH Urban Garden Center (UGC) in Pearl City. We answer plant questions, provide hands-on training opportunities, maintain garden displays and conduct public demonstrations at this 30-acre garden.
The UH Cooperative Extension Service and the UH Master Gardener program is dedicated to disseminating local, research based information promoting sustainable practices that affect ourselves, our neighbors and our local and global environment. Many UH CTAHR publications are available to the public for free, accessible by our searchable database.
If there is not a UH publication available on the subject you are interested in, we are trained to find research based information and other reliable sources of information.
Our Plant Helpline is available for calls or walk-ins 9AM-12PM, Monday – Friday. Our office is closed on holidays.
Master Gardeners are dedicated volunteers who disseminate researched based information to the public. We invite you to join us! We conduct a training class for new Master Gardeners every year, from January to end of May. We meet at the UGC Classroom 9AM -12PM, each Friday for 16 weeks.

Bring your home gardener question to our “Got a Plant Question” Booth at your local farmers market! Purchase UH Vegetable Seeds for your home garden!
Tips: When bringing plant samples with suspected plant disease be sure to bring new leaves AND old leaves, include flowers or fruits that show symptoms. Dead leaves or rotting fruit does not allow us to see all the symptoms of the problem! Pictures of the garden or plants showing stress is encouraged! Please read here for more information: Collecting Plant Disease and Insect Pest Samples for Problem Diagnosis.
