American Standard for Nursery Stock

The purpose of the American Standard for Nursery Stock, Z-60.1 is to provide buyers and sellers of nursery stock with a common terminology in order to facilitate transactions involving nursery stock. For instance, the standards establish common techniques for (a) measuring plants, (b) specifying and stating the size of plants, (c) determining the proper relationship between height and caliper, or height and width, and (d) determining whether a root ball or container is large enough for a particular size plant.

In other words, this book is a communication tool, and does not provide buyers with any assurance of the health or quality of the nursery stock being specified or sold.

This resource is useful for those that are trying to grade/assess nursery stock and make sure they are receiving what they have ordered.
