Napa County Master Gardeners Integrative Grape Team (IGT) was established in 2005 to provide home gardeners with information and education on all aspects of grape growing. The team consists of professional grape growers, hobby grape growers and others who are interested in this valuable Napa horticultural gem. The team provides workshops on pruning, trellising, soil health, conservation, farming styles and so much more each year.
Additionally, the team supports the UC Master Gardener Help Desk to answer grape growing related questions.
