Horticulture Professionals

Dave Pehling, 425-338-2400, will take commercial calls and walk-ins. He is an expert diagnostician, who can often do plant disease, insect, weed and plant identification and save you the delay and fee associated with sending a specimen to the WSU Puyallup Lab. University regulations do not allow Master Gardeners to handle commercial questions, other than to take down information, so please identify yourself as a horticultural professional.


Horticultural Professional Training

Offered to a limited number of applicants once a year in conjunction with the annual Master Gardener Training, which is held once a week Thursday daytimes January through March. Training is the same as the Master Gardeners receive but without a volunteer commitment, so tuition is $775. Full-Tuitions Applications for the 2018 training class are now available here.
