Ornamentals Management Committee

A strategic grower group consisting of representatives across multiple sectors and the Chairs of our Retail Suppliers and Amenity Suppliers groups. This group is instrumental in the HTA’s lobbying activity and gives direction to where efforts should be channeled, providing crucial insight into experiences of the industry and what the future of Horticulture may look like.  

This group generates strategies for member growers by sharing essential updates and discussing methods for overcoming challenges, outlining how the group can collectively influence the industry to protect and promote the interests of those working within it.

The Ornamentals Management Committee has seen success in improving communication with Government, Defra, other decision-makers, and between the industry and the Animal and Plant Health Agency.

Our group meets three times a year, virtually, at our central hub, Horticulture House, and for a walking tour around a member’s nursery or site. All the events are networking opportunities with like-minded individuals who share mutual concerns and relevant news from the sector. Over the last couple of years, we have seen significant changes in the industry such as labour shortages, the challenge of growing in peat-reduced growing media, the future of research and development, supply and demand, and biosecurity. This group remains at the forefront of the changes offering support and knowledge to each other, other members’ and throughout the Horticulture industry.
