PARLIAMENTARY WRITTEN QUESTION
(2 February 2026)

To ask the Secretary of State for Environment, Food and Rural Affairs, what assessment has been made of the performance, environmental impact, and scalability of peat-free alternatives within horticulture.

Asked by:
Maya Ellis (Labour)

Using the Responsible Sourcing Scheme for Growing Media methodology to assess the environmental impact of different types of growing media, it has been shown that all materials have an environmental impact, but for the most part, peat-alternatives have a lower environmental impact.

We have funded research which has demonstrated that peat-alternatives can perform the same or better than peat-based growing media in commercial horticulture and we are continuing to fund the Royal Horticulture Society Transition to Peat-free Fellowship, which has already demonstrated successful peat replacement in commercial horticulture for some of the previously believed more challenging plants, e.g. ericaceous. We will continue to work with the industry to understand barriers to scale up.
