What if we took a closer look at what’s happening beneath our feet? On Saturday, December 5, 2026, the Maison de la Planète in Boulogne-Billancourt, in the Hauts-de-Seine department (92), is hosting a free Soil Day. The program includes hands-on workshops, an introduction to composting, a collaborative mural and a talk on permaculture. An outing for all ages to discover the soil that sustains us!
