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.

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

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.

Spring Renovation Workshop—Saturday, March 31—10am to 3pm

Fall Renovation Workshop—Saturday, September 15—10am to 3pm

 

Renovation Workshops are a popular hands-on all-day event that features a rare 5:1 student-teacher ratio and real-world experience. Students will learn pruning and creative solutions for the overgrown garden through hands-on experience as an entire yard is renovated during the class. Topics discussed include pruning, transplanting, and landscape maintenance.  The group will move through an overgrown landscape while instructors give on-the-spot evaluations of plants and demonstrations of pruning. Workshop participants will then cycle between jobs to learn what the landscape has to offer.  These workshops typically take place at a private residence within King County selected for its neglected state and diverse plant material.  All participants receive a pruning DVD and handouts on various pruning topics.

Pre-registration is required. Cost is $85 (PlantAmnesty members) or $95 (non-members)
