Master Gardener Workshops

CTAHR has active Master Gardeners (MG) Programs in Pearl City, Lihue, Kahului, Kona and Hilo. The Pearl City Urban Garden Center is our flagship facility for home and urban gardening and is also home to our first and largest MG Program in Hawai‘i. The MG programs provide support to the College by helping with open houses, fairs, gardening demonstrations, answering questions telephoned in through the Home Gardening Helpline, and in many other ways.

Our lab supports the Master Gardener program by providing training opportunities across the state in topics relating to sustainable and organic gardening techniques.
