RHP has published a factsheet about horsetail. This factsheet is part of a series on specific topics related to potting soil and growing media.
The factsheet on horsetail can be found in the knowledge base of RHP. The factsheet is intended to inform certified companies, their customers, and other stakeholders about this tough and difficult to remove weed. It is frequently seen in public spaces and gardens. What are the requirements of the RAG quality mark, and what should users take into account?
About once a quarter, a new factsheet will be added to the knowledge base. Topics that are planned next are, for example: unfertilized potting soil, (liver) moss, microplastics and PFAS.
