The Master Gardener Helpline
Hawai‘i Island Master Gardeners are trained volunteers who specialize in giving advice and assistance to home gardeners on pests, diseases and cultivation of plants in Hawai‘i. Research-based horticultural information is provided primarily through the Master Gardener Helpline. Home gardeners can call during office hours and ask to speak to a Master Gardener or drop by the office in person.
Beginning August 27, 2021, in-person visitors to the Komohana Research & Extension Complex will need to show proof of COVID-19 vaccination, or a negative COVID-19 test within the last 7 days.
