Workshop-type educational gardens with topics that echo the gardens in motion can be visited since June 2022 in the second semi-circle. These gardens in the Vast Circle are dedicated to transferring knowledge: garden of colours and scents, garden of medicinal and aromatic plants, garden of ancient cereals, permaculture garden, etc.
The priority given to respecting the site’s natural resources is a challenge, a source of creativity and a springboard for learning for students: minimised soil sealing, use of mulch to minimise drying of soil, development of composting over the site, precedence given to local materials and plants that do not need watering, etc. Classified a Sensitive Natural Area and with the Refuge LPO label, the Saline royale has been managed without herbicides since 2014.
