Which of the following is NOT covered under nursery stock regulations?

The correct answer is that processed plant products are not covered under nursery stock regulations. Nursery stock regulations primarily focus on live plants and seedlings that are intended for ornamental use, cultivation, or propagation. This includes ensuring that these live plant items are healthy, pest-free, and properly labeled.

In contrast, processed plant products, such as dried herbs, cut flowers, or other products that are no longer living and have undergone some form of processing, do not fall under the same regulatory framework. They are typically governed by different sets of laws pertaining to food safety, packaging, and sales, rather than the horticultural standards applied to nursery stock. This distinction is essential for understanding the scope of nursery licensing and the specific regulations that apply to various categories of plant products.
