The Sandoval Extension Master Gardeners offer a variety of classes, for master gardeners and the public. Classes are offered at various times and locations. Some require a fee while others are free. For some classes space may be limited and pre-registration advisable.

Sandoval Extension Master Gardener Training Classes

The Master Gardener Training Program is offered each year for those wishing to become an Intern Master Gardener.

The current curriculum presents core classes over a 15-week period starting in January plus elective classes and hands-on workshops. These classes are based on material developed by New Mexico State University and other specialists and are intended to provide a basic understanding of horticulture and practical applications for the home gardener.

Classes are pre-recorded for online presentation followed by online live Q&A sessions to meet COVID-19 restrictions and provide maximum time flexibility in accessing classes. Veteran Master Gardeners may take these classes for continuing education credit.
