The Royal Horticultural Society (RHS) introduces new guidance for exhibitors at the Chelsea Flower Show encouraging the use of peat-free compost, citing environmental concerns. According to the reports, the guidance is prompting some growers to question their participation, leading to a dispute over how the new rules are applied and whether they will affect growing methods and plants prepared for the show. The disagreement centers on the RHS’s push to move away from peat-based compost and the practical implications for horticultural businesses and suppliers that rely on existing substrates. The RHS’s position focuses on environmental impact and the benefits of peat-free growing media. The situation is reported as an ongoing row, with growers weighing whether they can comply with the peat-free direction in time for the event. The controversy is framed as part of broader changes in environmental standards affecting horticulture and how trade practices align with show requirements.
