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 2017 Master Pruner Series, 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.

To receive a Master Pruner Certificate of Graduation, students are required to attend all twelve lectures (at either location) and three workshops provided by PlantAmnesty. A graduation ceremony is held each fall. Seminars attended at either location count towards the Master Pruner certificate, but the programs are administered and priced separately by the host organizations. 


Workshops are designed for home gardeners, landscape professionals, and students enrolled in the Master Pruner Series.  Complete details and materials are sent to students a few weeks prior to each workshop.  Do you know a yard that needs an Extreme MakeoverWe are on the look-out for renovation workshop sites.
