Companies that intend to market and trade propagating material (within the EU) for vegetable crops (vegetable plants, vegetable seeds, soft fruit, shallots,onion sets and garlic) must register with Naktuinbouw. Companies such as garden centres or hardware stores, that intend to supply or sell to consumers only, do not need to register.

About the inspection

This registration obligation is based on the Seeds and Planting Materials Act and the Dutch Plant Diseases Act. As a supplier of propagating material in the Netherlands, you have to be registered with Naktuinbouw. We are the authority tasked with monitoring companies active in the floriculture sector. This is obligatory under the terms of European Trade Directives and Dutch legislation.

Approximately 3,000 registered companies are listed with Naktuinbouw. These include breeders, propagators, producers, processing companies and traders. If your company is registered with Naktuinbouw, your propagating material may be traded within Europe. 

Read this brochure for more information on inspections.


European trade directives apply within each sector in horticulture. The terms of these directives must be taken into account. Directive 2002/55/EG and 2008/72/EG are basis for vegetables.
