GRADING

We grade to accepted industry standards of size, quality and count. We urge our customers with questions on expected grades to call and discuss our grading standards in advance of ordering. We also offer custom grading on large orders at a negotiated rate.

Height grades are measured from the root collar or soil line. Consideration in height grading is given to the shoot or top form, although acceptable limits will depend very much on the species and normally intended use.

Generally, our caliper graded stock is intended for rootstock purposes and in grading minimal consideration is given to the form and height of the top of the plant. Caliper grades are measured above the root collar and the following equivalences are adhered to in our catalog:

B-GRADE

B-grade is characterized as ornamental nursery stock that has been discounted due to cosmetic flaws/variations which do not meet our normal industry standard. This product has been sized similar to our high-quality A grade and entered into inventory as a result of customer request for reduced-cost, ornamental stock. Samples are available upon request if quantities are sufficient. B-grade material is not available until we are sold out of our A-grade stock.
