The Mien Ruys Gardens have been managed by the Mien Ruys Garden Foundation since 1976.

The aim of the foundation is to keep the Garden open for a broad section of the public and find means to achieve this. Keeping the style of Mien Ruys in mind experiments in plantation and garden materials are carried out and passed on to garden lovers and contemporary gardeners. In this way a contribution is made to the widening of interest in and knowledge of garden architecture, plantation and garden maintenance. The Mien Ruys Garden Foundation is a non-profit organization.
