RHP certified mulch
RHP certified mulch and any additives must meet the requirements for plant safety, based on the RHP certification. For this reason, not just any mulch may be used under the RHP quality mark. Standards and requirements have been drawn up by RHP, whereby the origin, production and any necessary sanitation process of the mulch are monitored. This offers the most security as possible that the mulch can be applied safely, without any risks to the culture.
