The first major garden & nature event in Brussels
A public event, qualitative and inspiring, at the intersection of gardening, ecology and conviviality
The Gardens of the HippoDrohme are a new annual event dedicated to gardening, biodiversity and everyday ecology, inspired by the most beautiful plant festivals in Europe but adapted to the Brussels spirit.
A friendly meeting at the gates of the Soignes forest, aimed at all audiences, both amateurs and enthusiasts of gardening and nature between Uccle and Watermael-Boitsfort.
The 4 pillars

Plants, vegetable garden, balconies, terraces, biodiversity.
The event will highlight concrete solutions for gardening in the city, on balconies, terraces or small gardens, through a selection of specialized exhibitors and practical activities.
