RHS medal for Catherine Dawson
In recognition of outstanding contributions to horticultural science and sustainability, the RHS has presented Melcourt’s Catherine Dawson with the Veitch Memorial Medal.
A pioneering soil scientist and horticultural innovator, Catherine Dawson’s work has revolutionised the development and adoption of peat-free growing media. With a background in soil science and agriculture, she has spent more than 30 years driving the horticultural industry toward sustainable, high-performance alternatives to peat.
Her expertise and leadership at Melcourt led to the creation of SylvaMix and SylvaGrow, groundbreaking peat-free alternatives that have set the standard for commercially viable, environmentally responsible growing media, now widely used by both professional growers and home gardeners.
As a respected industry voice, Catherine has played a key role in government and industry collaborations, including chairing the Growing Media Association, leading the Responsible Sourcing of Growing Media Scheme, and contributing to the RHS Transition to Peat-Free Fellowship. Her influence extends across the sector, advising academic institutions, nurseries, and royal residences, while also shaping policies that support the future of sustainable horticulture.
