Juliet Sargeant is a garden designer who believes that gardens can do so much more than look good.

Nick Wray | The Development of the University of Bristol Botanic Garden

Nick Wray delivers a fascinating talk on the move and redevelopment of the University of Bristol Botanic Garden, of which he is curator. This marked the first university botanic garden to be redeveloped in the UK for over 40 years. 

As many Botanic Gardens are tied up in the constraints of their heritage, the opportunity to redesign an educational and research garden, from its layout to its collections, provided a unique opportunity to create a space specifically designed to fulfil the educational needs of today. The University of Bristol Botanic Garden is that garden.

Dr Mark Spencer | Murder Most Florid: The power of forensic botany

Plants too are silent witnesses to crimes. Their presence in many crime scenes can help an investigator identify a suspect or locate a victim. Apparently mundane plants such as brambles and nettles can provide valuable insights into when a crime was committed. Fragments of leaves and seeds embedded in soil on the footwear of a suspect can place them at the scene.

Join us to hear from Dr Mark Spencer, experienced consultant and forensic botanist who has worked on various missing person enquiries, murders and other serious crimes, about one of the more obscure yet fascinating fields of our industry.



Georgi Ennis | My Life in the Trees

Britain remains one of the least-wooded countries in Europe and the tiny area of surviving ancient woodland is still under threat. Join Georgi Ennis, Kew-trained arboriculturalist turned Woodland Officer for the Forestry Commission, for a guide to protecting, expanding and promoting the sustainable management of woodlands. 

Georgi has not only climbed trees, but has also climbed the ranks of the male-dominated industry of arboriculture. She spent five years climbing trees as a sub-contractor before coming to Kew to train in arboriculture. Now she manages thousands of hectares of woodland in South Hampshire and the Isle of Wight for the Forestry commission, but still finds time to do tree surgery on the side!



Prof. Duncan Cameron | Decoding the Secret Language of Soils

The soil is the foundation of most terrestrial life on Earth, yet its staggering complexity and value as a resource is often ignored. Most undervalued of all is the amazing array of organisms that make soil their home. Duncan Cameron, professor of Plant and Soil biology and co-Director of the Institute for Sustainable Food at the University of Sheffield decodes the language of life underground.

John Little | Kicking the Habit: Designing without topsoil

John Little is a brownfield gardener and creator of Grass Roof Company. His job consists of getting soils, plants, biodiversity and joy into new infrastructure and urban places.  

Come and hear about the huge potential of creating diverse plant communities and important habitats by freeing ourselves from the constraints of topsoil. John will look at how using mineral soils, construction waste and sands can help to redress the ‘bland-landscaping' within public space, developments and highways. Taking the open mosaic habitat as our template he’ll look at the possibilities of using soils to dictate the plants, invertebrates and future maintenance of new landscapes.

Prof. James Hitchmough | New garden and landscape plants: Indulgence or necessity in an era of climate change?

Climate change is widespread, rapid and intensifying, and across the globe the capacity of plants to cope is being challenged. This doesn’t just apply to the natural world, our cultivated plants also need to change if horticulture is to keep up. Dr James Hitchmough, Professor of Horticultural Ecology, answers the important questions: Where do new garden and landscape plants come from, and who will lead the charge?

Howard Sooley | Derek Jarman, Prospect Cottage and Me

Derek Jarman died in February 1994, leaving behind a fine legacy of films, paintings, books, and the wonderful garden of Prospect Cottage. As a garden it is unusual and inspirational, existing outside of the horticultural tradition in which cultivated space and nature are distinct.
