Master Gardener Volunteer & Home Horticulture Training
Master Gardeners are trained volunteers who provide educational information to Cooperative Extension clientele. They undergo intensive training.
Course topics include basic botany; climate and soils; composting; water and irrigation; ecosystems and native plants; plant selection, planting, staking and pruning; woody plants (fruit and ornamentals); vegetables and annuals; weed management; wildlife damage control; plant diseases; entomology; integrated pest management and pesticide safety.
The primary focus of the volunteer work is providing science-based horticultural information to the community. Some examples of volunteer work are:

- giving talks, demonstrations, etc. to groups
- sharing horticulture information at festivals, farmers' markets, etc.
- assisting students in school wildlife habitats
- providing horticultural advice to individuals, groups, and establishment
