The Modern Garden Conference


Called ‘The Modern Garden’, the PlantNetwork Conference 2021 looks at technological developments in horticulture, and new innovations and thinking as well as topics of growing importance such as climate change, sustainability, and plant health threats. It is also an opportunity to look at the role of traditional skills alongside technological advancements. Individual sessions look at different topics that will have an impact on modern gardening, providing an opportunity to hear the latest research findings and practical interventions being trialled in horticulture.

Explore the sessions in more detail using the session tabs below, and see the ‘Programme’ at the bottom of the page for further information.

More detail about the individual sessions:

Innovations in Horticulture

Compare modern gardens with, for example, gardens of the late Victorian period and two things will be immediately noticeable: modern gardens have far fewer gardeners and much more machinery. In this session, we look at the latest innovations in gardening in the 21st century. The internal combustion engine revolutionised gardening in the 20th century, what will change our gardening practice this century?

Session takes place 2-4pm.

Chair: Kate Hughes, Royal Botanic Garden Edinburgh

Speakers:

Dominique Exmann – MD of Candide Gardens
Dr Waheed Arshad – Botanical Scientist for Hortis

Ecosystem Services & Multifunctionality

Natural capital and ecosystem services offer a new way of thinking – and potentially a new income stream – for gardens. The Office of National Statistics have estimated that there were 6,754 public gardens and parks in 2017 providing the majority functional green space (approx. 37,500 hectares) as well as a further 530,000 hectares of residential gardens and almost 8,000 hectares of allotments and community growing spaces, all of which offer services to society through the provision of flood protection, carbon sequestration, noise pollution mitigation, pollination services and health and wellbeing benefits (ONS, 2018). There are significant contributions that can be made to local communities, wider society and even the global battle against climate change through consideration of the ecosystem services and natural capital provided by gardens. In this session, we explore how gardens can make use of these concepts and provide a new way of thinking about gardens as multifunctional spaces with the potential to make significant social, economic and environmental impact.

Traditional Skills in Modern Gardens

Traditional gardening skills – from growing and cultivating plants to garden landscaping – have huge potential in the Modern Garden as they often make use of what is available in the garden, contributing to more sustainable practices. Whether it is growing coppice for garden building materials and plant supports to learning techniques such as scything for meadow management, there are many different crafts and skills to be employed. In this session, we explore some of these approaches and crafts, and discuss their role alongside more technological developments. Scything alongside a robot mower perhaps?

Session takes place 5-7pm.

Re-writing the Rules Workshop

Session takes place 2-4pm.

You are invited to participate in this workshop which will consider old, new and re-imagined horticultural practice. Why do we do certain activities in certain ways? Is it because we have always done it that way, have evidence that this is ‘good practice’ or simply a best guess? It is an opportunity to consider new approaches, new ways of doing things and/or the reasons behind traditional approaches.

Six topics have been selected for small group discussion, with the aim of creating a briefing note to help inform the development of new practices or principles in horticulture – or stimulate research/further discussion.

An excellent networking opportunity too!

Our six topics:

  • What and when to water: in an increasingly water scarce world, what is the best practice for watering plants from new plantings to issues of timing, methods, amounts…?
  • Weedy lawns: can perspectives of what makes an acceptable lawn change to include greater acceptance of ‘weeds’, longer grass and reduced mowing, miniature meadows etc.?
  • To dig or not to dig: is there still a role for double digging and how does this fit into soil management regimes that include green manures, mulching etc.?
  • Holistic plant health and the microbiome: do we need to reconsider what we mean by ‘plant health’ as we look to transition from treating pest and disease problems to preventing them by growing more resilient plants?
  • Growing media in a peat-free world: what makes a good substrate and how do you source this? Do we need to make our own substrates?
  • Re-interpreting the garden: are public gardens just about plants and plant placings or are they more than that? Are gardens gateways to greater environmental awareness such as climate change, food production, biodiversity, and sustainability? Do they tell more stories than simply what or where a plant is such history, diversity, inclusion etc.?

We will be joined by Dr Geoff Dixon and Doug Stewart who will help provide background to our practices and reflect on why we might need to enact changes to our horticultural approaches.

Gardening in 2046 – free session open to all

Session takes place 5-7pm.

The first hour includes a short series of Lightning Talks – five minutes long and showcasing a topic relevant to Gardening in 2046. Confirmed speakers are from the Sustainable Landscape Foundation, Silent Space, Young People in Horticulture Association, National Botanic Garden of Wales and Trewithen Gardens.

This will be followed by an hour-long panel discussion on what gardens in 2046 might be like. A panel of three with a chair will all discuss what they see as being the big issues of the future and what changes might be made to public gardens and gardening. Event participants will be asked to submit questions for the panel to discuss.

The session chair is Philip Turvil, Eco Business Director of the Field Studies Council and panelists are Mark Brent (Curator of Oxford Botanic Garden), Kirsty Wilson (of the Royal Botanic Garden Edinburgh and presenter on BBC’s The Beechgrove Garden) and Cailean Iain Stewart (from the Royal Horticultural Society).
