Master Pruner Series and Certification

Each year PlantAmnesty expert instructors teach pruning techniques in our twelve-part Master Pruner Series. Topics include: artistic pruning, fruit trees, landscape renovation, Japanese garden pruning, ornamental vines, pruning roses, and species-specific tutorials. This series provides students with a solid base in the science and practice of selective pruning. Students are given access to a broad range of pruning information at each two-hour presentation. 

For a full description of the program, including class descriptions, schedule and fees, see our Full List of Classes and Workshops.  Classes are open to master gardeners, landscapers, gardeners, horticulture students as well as the general public. Students may complete Master Pruner classes individually or complete the entire series.
