EGHN - Botanic Garden Münster

Management of orangery plants in Historic Gardens

Webinar: 7th of November 2023
Practical Workshop: 10th – 11th of September 2024, at Het Loo in The Netherlands

Orangeries can be considered as a kind of symbiosis between plants and garden architecture. Some plants would not be able to survive in our climate without the protection delivered by the orangeries and without the plants, orangeries would be meaningless and not even exist.

The exchange of knowledge about the care and maintenance of the plant stocks in the orangeries, about the preservation and development of the orangery buildings and related outdoor spaces and the about plant design and practical horticultural expertise are important.

In the webinar we discuss orangeries, their plants and their structures. We cover planting substrates, water and nutrient requirements, plants in the winter quarters, pruning and repotting. When it comes to structures, we address the history of orangeries, their modernisation (e.g. to reduce the carbon footprint) and the design of the spaces around the buildings.


The outcomes of the webinar will then be followed up and practical guidance and advice will be shared. EGHN, Schloss Dyck Foundation and Paleis Het Loo are working together to develop av program for the practical, on-site workshop. The venue for the workshop is Het Loo in Apeldoorn in The Netherlands, at Koninklijk Park 16.
