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. Home gardeners can also email us outside of helpline hours and we will get back to you when we are in the office on Friday. 

Also available are UH CTAHR Seeds for sale every Friday - see what is available CURRENT SEED LIST / PRICING
