The objective of this Standard is to provide criteria for those who grow, specify or purchase tree stock for landscape use. The use of such criteria enables quality tree stock to be identified, regardless of the production method used to grow them.
This Standard specifies the criteria for the assessment of above-ground and below-ground characteristics of tree stock that are to be supplied for landscape use. It covers container-grown, containerized, bare-rooted and ex-ground tree stock, and can be applied to all stages of growth.
The specifications and criteria in this Standard apply to all methods of production systems and styles of containers.
NOTE Tree stock are not manufactured articles that can be produced to an exact specification. Variability between tree stock is expected, as trees are living organisms and individual differences are to be expected.
This Standard does not apply to palms, or tree stock that is specifically produced for topiary, espalier, bonsai, pollarding or coppicing. This Standard does not apply to tree stock that has been transplanted from a landscape situation (not a production nursery) to places other than a production nursery.
