PlantAmnesty Master Pruner Series
& Certification

PlantAmnesty founder and pruning expert, Cass Turnbull, and other expert guest instructors teach topic-specific pruning techniques in PlantAmnesty’s Master Pruner seminar series. The classes in the series are open to the public, master gardeners, landscapers, gardeners, horticulture students, and members of PlantAmnesty. The series was designed to provide a solid base in the science and practice of selective pruning. Students are given access to a broad range of pruning information while attending a 12-part series of two-hour PowerPoint presentations. Topics include the following:

  • landscape renovation,
  • pruning roses,
  • fruit trees,
  • ornamental vines,
  • artistic pruning,
  • Japanese garden pruning,
  • tree pruning, and
  • species specific tutorials
To receive PlantAmnesty’s Master Pruner certificate, students must attend all lectures and three hands-on, all-day workshops held annually in the King County, which are available through PlantAmnesty. See the list of upcoming classes and workshops below.

Students may take Master Pruner classes individually or complete the entire series. Students completing the seminar series and requisite workshops receive a Certificate of Graduation. The seminar series is available three ways:

  1. From PlantAmnesty, on second Sundays of the month at Magnuson Park in NE Seattle. Preregistration is not required for the Magnuson Park classes. The classes held at Magnuson Park are in building #406 (the Brig) at 7400 Sandpoint Way NE, Seattle 98115. No classes are held in August or December.
  2. Classes may be held through the Snohomish Master Gardeners in South Everett. Check their website for a schedule. See http://snohomish.wsu.edu/ for details.
  3. Throughout the winter at the University of Washington’s Center for Urban Horticulture's ProHort program on the second and forth Thursdays of the month (two lectures per day). Preregistration is required. See http://depts.washington.edu/uwbg/education/prohort.php for details.
Seminars attended at any location count toward a Master Pruner certificate, but the programs are administered and priced separately by hosting organizations. See specific class listings for costs and class descriptions.

People who join PlantAmnesty at a Seattle Magnuson Park class get the first class free, receive an informational two-hour DVD on pruning, and get a discount on all future classes. Seattle classes are interchangeable with the Master Pruner series offered on weekdays at the Snohomish Master Gardener site.


The classes are just $20 each for the general public; $15 for PlantAmnesty members, $5 for horticulture college students and native Spanish speakers. No pre-registration for classes at Magnuson Park is necessary.  Just show up and pay at the door. Questions? Email PlantAmnesty or call 206.783.9813
