Plant Industries inspectors look for insect and plant disease pests on nursery stock. The Delaware Department of Agriculture’s Nursery section is responsible for the administration of the Delaware Nursery Law (Title 3 Chapter 13 – Nurseries and Nursery Stock Law). Delaware law defines nursery stock as “any plant for planting, propagation, or ornamentation, including, but not limited to:
a. All plants, trees, shrubs, vines, perennials grafts, cuttings and buds that may be sold for propagation, whether cultivated or wild, and all viable parts of these plants.
b. Any other plant or plant part, including cut Christmas trees or any non-hardy plant or plant part, including but not limited to, annuals, bedding plants and vegetable plants.”
In addition, the Nursery section issues certificates of inspection, phytosanitary certificates, and Nursery Licenses to businesses engaged in a nursery or nursery-related business within the state. Certification and inspections are conducted to prevent the introduction of unwanted plant pests into Delaware and facilitate grower shipments of nursery stock to other states and countries.
Anyone directly engaged with the distribution of plants, plant products, plant material, nursery stock, or horticultural products is required to let the Delaware Department of Agriculture know that they are conducting this business. They must obtain a nursery industry license before starting business operations. The nursery industry licenses are valid for one year (January 1 – December 31) and must be renewed annually.

The Invasive Plants Law went into effect on July 1, 2022, prohibiting any person from importing, exporting, buying, selling, transporting, distributing, or propagating any viable portion, including seeds, of an invasive plant in Delaware. An invasive plant includes any living part, cultivar, species, or subspecies not native to Delaware that has the potential to result in widespread dispersal and establishment; out-compete other species in the same area; exhibit rapid growth or high seed or propagule productions; or become established in natural areas in the State.
If an individual or group is interested in obtaining an exemption for a cultivar from the Invasive Plant List, the Petition to Exempt Cultivar NEW! must be completed and submitted for review.
