Commercial Diagnostic Services
You may send commercial samples for diagnosis directly to the WSU Puyallup Plant Clinic and Diagnostic Laboratory. We no longer have a professional diagnostician on staff and WSU regulations do not allow Master Gardeners to answer commercial diagnostic questions.
Private Pesticide Applicator License
Information about pesticide applicator licensing is available from the Washington State Department of Agriculture. Study materials may be purchased at our office and some of the exams are also given at our office. Review the schedule and then call 1-877-301-4555 to make an appointment.
Horticultural Professional Training
Horticulture Professional Training that is offered in conjunction with the annual Master Gardener Training, is expected to resume in 2022.
