Sustainable development of public and private outdoor spaces is achieved not just through the choice of materials and their sustainable production, but also primarily through a future-oriented design and planting choices. The art is in looking closely at nature. Creating a balance in which nature maintains itself and can continue to develop. The individuality and diversity of nature forms the starting point from this perspective. For the planting choice, this means the natural growth and natural growing-location conditions for a tree should be taken into account, for example. This way the planting will flourish now and in the future. And the desired green experience will be guaranteed not only in the short term but also in the long term.

More and more companies and institutions are recognising the importance of sustainability. The 450-hectare Ebben nursery operates sustainably, in accordance with the Dutch 'Milieukeur' ecolabel. Sustainable cultivation is not only better for the environment, but also produces better trees. The plant learns to protect itself in a normal habitat and is stronger when it is later positioned in a public space or garden. Ebben Nurseries works with biological resources for fertilisation and disease control, for example, and has managed to significantly reduce the use of pesticides by planting strips of grass and mixed flowers between the trees. Rain and irrigation water are also collected and reused, after natural purification through the ground.
