Q: What is meant by the term "Certified Grape Planting Stock"?

Answer: "Certified grape planting stock" means vines, rooted cuttings, cuttings or grafted plants taken or propagated directly from foundation vines or registered. "Certified" planting material is the result of a process that is outlined in State code and is administered by the State's Dept. of Agriculture. It is a process where a nursery acquires State Registered Foundation planting stock and plants this material in a State registered Increase/Mother block for subsequent propagation purposes. The resulting propagated vines from the Increase/Mother block can be sold as "State Certified" and can be tagged as such. It is the responsibility of both the State's Dept. of Agriculture and the certified nursery to maintain the 'Registered' status of the Registered Increase/Mother blocks. The Certification tag is the end result of a process controlled by the State's codes. 'Certified' means propagated from Foundation or Registered vines and monitored under the watchful eye of the Washington State Department of Agriculture.
