Published Jan 2025: The Horticulture Code of Conduct (the Code) applies to traders (merchants and agents), and growers, who deal directly with each other in horticulture produce. As a grower, these questions will help you understand and negotiate a Horticulture Produce Agreement (HPA) with a merchant or agent. Understanding your HPA before you enter into it can help protect your rights under the Code and reduce the risk of a dispute in the future.
