The Future of Gardens: Climate, Diversity and Inclusion
Gardens are changing.
The climate in which they grow is changing, the wildlife they support is changing, and the way people use and value outdoor spaces is changing. Future gardening will therefore involve more than selecting attractive plants. It will require an understanding of climate, water, soil, biodiversity, resources and the different people who use gardens.
A garden can be both a private space and part of a much larger environmental system. Collectively, gardens contribute to wildlife habitat, water management, urban cooling, food production and human wellbeing.
The future of horticulture lies in designing gardens that can perform these different functions while adapting to changing conditions.
1. Gardening in a Changing Climate
Climate change is altering the conditions under which plants grow.
For gardens in the UK, important changes include increasing temperatures, periods of drought, intense rainfall and other forms of extreme weather. Seasonal patterns may also become less predictable, affecting flowering, plant growth, pest activity and disease development (IPCC, 2023; Met Office, 2022).
The challenge is therefore not simply to grow plants in warmer weather.
A resilient garden must cope with variation.
A summer may contain both drought and intense rainfall. A mild winter may be followed by a late frost. A plant may experience a warm spring followed by an unusually cool period.
Garden design must therefore account for both normal conditions and extremes.
2. Designing for Change
Traditional horticulture often begins with the question:
What conditions does this plant require?
Future horticulture must add another question:
How might those conditions change?
Plant selection should consider tolerance of heat, drought, wind, waterlogging and changing seasonal conditions. Site assessment becomes particularly important because gardens can contain very different microclimates.
A wall may create a warm, dry environment.
A mature tree may create shade and root competition.
A low-lying border may remain wet.
An exposed lawn may experience considerable wind and evaporation.
The principle of “right plant, right place” therefore becomes increasingly valuable. Selecting plants according to the conditions they are likely to experience reduces the need for excessive irrigation, protection and replacement.
3. Diversity as a Form of Resilience
Plant diversity can help spread environmental risk.
If a garden contains only a small number of plant species or closely related cultivars, a particular pest, disease or extreme weather event may affect a large proportion of the planting.
A more varied planting scheme creates differences in:
- drought tolerance;
- disease susceptibility;
- flowering time;
- growth habit;
- root structure;
- habitat value; and
- response to temperature.
This does not mean that simply increasing the number of species automatically creates a resilient garden. The plants need to be appropriate to the site and should provide complementary ecological functions.
Diversity is most useful when it creates a range of characteristics rather than merely a long plant list.
The conservation of cultivated plant diversity is also important because existing varieties may contain characteristics that become valuable under future environmental conditions (RHS, 2025a).
4. Biodiversity in the Future Garden
Biodiversity includes the variety of organisms within an ecosystem, including plants, animals, fungi and microorganisms.
A garden can support biodiversity by providing:
- food;
- shelter;
- nesting sites;
- flowering plants;
- water;
- soil habitat;
- deadwood;
- leaf litter; and
- connected areas of vegetation.
Different organisms require different conditions. A manicured lawn provides a different habitat from a hedge, pond, flowering border or mature tree.
The future garden should therefore be considered as a mosaic of habitats.
This approach can be more valuable than attempting to make every part of a garden equally tidy or uniform.
Gardens can also contribute to wider ecological networks. Hedges, trees and other planted areas can connect gardens with parks,
woodland, allotments and other green spaces (RHS, 2025b).
5. Plants for a Changing Wildlife Calendar
Climate change can affect the timing of biological events.
Plants may flower earlier, while insects and other organisms may alter their seasonal activity.
A diverse range of flowering plants can help provide resources across a long period of the year.
Rather than concentrating all flowering into a short spring or summer display, gardens can include plants flowering from late winter through to autumn.
This provides continuity of nectar and pollen resources for insects.
However, biodiversity is not simply about planting more flowers.
Wildlife also requires places to shelter, reproduce and overwinter.
A garden containing flowers, dense vegetation, trees, shrubs, soil habitat, water and undisturbed areas can therefore support a broader range of organisms than one designed around flowering alone.
6. Water: Too Much and Too Little
Water management will become increasingly important.
Climate change can increase the frequency or severity of both drought conditions and intense rainfall. Gardens therefore need to manage water rather than simply remove excess water or add more through irrigation.
Useful approaches include:
- collecting rainwater;
- improving soil structure;
- using suitable mulches;
- reducing unnecessary bare ground;
- creating rain gardens;
- using permeable surfaces;
- directing runoff into planted areas; and
- choosing plants according to local moisture conditions.
A rain garden, for example, can temporarily receive and hold runoff while supporting suitable vegetation.
Water can therefore become part of the design rather than simply being treated as a problem.
The RHS identifies water conservation, rain gardens and healthy soils as important components of climate-resilient gardening (RHS, 2024; RHS, 2026a).
7. Soil as the Foundation
Climate-resilient gardening begins below ground.
Soil provides physical support, water, nutrients and habitat for microorganisms. Its structure influences both drainage and water retention.
Compaction can reduce pore spaces, restricting root growth and reducing the movement of air and water.
Organic matter contributes to soil structure and supports biological activity, although the appropriate management depends on soil type and land use.
Plants themselves contribute to soil development. Roots create channels, dead plant material contributes organic matter, and microorganisms participate in decomposition and nutrient cycling.
Healthy soil therefore connects several elements of the future garden:
plant growth + water management + biodiversity + nutrient cycling.
8. Reducing Resource Use
Climate-conscious gardening also requires consideration of the resources used to create and maintain a garden.
These include:
- water;
- fertilisers;
- pesticides;
- plastics;
- growing media;
- machinery;
- fuel;
- electricity; and
- transported materials.
The future garden should aim to use resources efficiently and avoid unnecessary inputs.
Examples include:
- collecting rainwater;
- composting suitable garden materials;
- reusing containers;
- repairing tools;
- sharing equipment;
- reducing unnecessary irrigation;
- choosing durable materials; and
- reducing reliance on peat-based growing media.
The principle is not that every garden must operate without external inputs. Rather, resources should be used deliberately, with consideration of their environmental cost.
9. The Circular Garden
Natural ecosystems operate through cycles.
Leaves fall.
Organic material decomposes.
Nutrients return to the soil.
Plants absorb them again.
Gardens can imitate some of these cycles.
For example:
garden residues → compost → soil organic matter → plant growth
fallen leaves → leaf mould → soil amendment
rainfall → water storage → irrigation
pruned branches → habitat or mulch
This approach reduces waste and keeps useful materials within the garden for longer.
A circular approach can also change the way gardeners think about materials. Something previously regarded as waste may become a resource when its biological function is understood.
10. Managing Pests and Diseases
Changing climate conditions may influence the distribution and seasonal activity of pests and pathogens.
However, the response should not simply be to increase pesticide use.
Integrated Pest Management (IPM) provides a more systematic approach.
It begins with observation and identification.
The gardener asks:
- What organism is present?
- Is it actually causing significant damage?
- What environmental conditions are contributing?
- Can the problem be prevented?
- Are natural enemies present?
- Is intervention necessary?
Management can then combine cultural, physical, biological and, where appropriate, chemical methods.
The objective is to maintain healthy plants while avoiding unnecessary disruption of the wider ecosystem.
This approach also recognises that insects and microorganisms are not automatically harmful simply because they are present.
11. Gardens for People
A garden is an ecological system, but it is also a human space.
People use gardens for very different reasons.
They may be places for:
- growing food;
- recreation;
- exercise;
- education;
- social interaction;
- relaxation;
- cultural expression;
- wildlife observation; and
- therapeutic activities.
The future garden therefore needs to consider human diversity alongside biological diversity.
There is no single type of gardener and no single way of experiencing a garden.
12. Accessibility
Physical access is one of the first considerations in inclusive garden design.
Features may include:
- stable paths;
- appropriate path widths;
- manageable gradients;
- accessible entrances;
- raised beds;
- suitable seating;
- accessible water points;
- clear routes;
- suitable working heights; and
- areas where people can rest.
These features can benefit people with mobility impairments, but they can also make gardening easier for older people, children and anyone who finds prolonged bending or kneeling difficult.
Accessibility should therefore be incorporated from the beginning of the design process rather than added later.
13. Sensory and Neurodiverse Gardening
People experience sensory environments differently.
A garden may contain intense smells, bright colours, noise, movement, complicated pathways and dense planting.
For some people these characteristics may be enjoyable.
For others they may be overwhelming.
An inclusive garden can provide choice by combining different types of space:
- quiet areas;
- open areas;
- sheltered spaces;
- highly planted areas;
- simple routes;
- sensory planting;
- places for observation; and
- social spaces.
The purpose is not to assume that everyone within a particular group has the same preferences.
Instead, good design provides different ways of using and experiencing the garden.
14. Cultural Diversity
Gardens also express culture.
Plants may have significance as:
- food crops;
- medicinal plants;
- religious plants;
- traditional materials;
- ornamental species; or
- symbols associated with particular communities.
Community gardens can provide opportunities for people to share horticultural knowledge and growing traditions.
Inclusion is strongest when communities participate in deciding what is grown and how spaces are used rather than simply being represented through decorative planting.
A garden can therefore become a place where different forms of horticultural knowledge meet.
15. Equality and Equity
Access to gardens and green space is not equal.
Some people have private gardens.
Others live in flats or housing with little or no private outdoor space.
Access can also be affected by:
- income;
- location;
- age;
- disability;
- transport;
- availability of community facilities; and
- the cost of gardening materials.
This makes community gardens, allotments, school gardens and public green spaces particularly important.
Equality does not necessarily mean giving every person exactly the same resources.
Equity recognises that people may face different barriers and therefore require different forms of support to participate.
In horticulture, this might mean providing accessible beds, subsidised growing opportunities, shared tools or community growing spaces.
16. Gardens and Education
Future gardens can function as outdoor classrooms.
A single garden can demonstrate:
- photosynthesis;
- soil science;
- biodiversity;
- water cycles;
- climate adaptation;
- food production;
- plant propagation;
- pest management; and
- ecological relationships.
This is particularly valuable for children and young people because horticulture combines scientific knowledge with practical activity.
Gardens can also provide opportunities to develop the green skills required for horticulture, landscape management, conservation and environmental work.
The RHS identifies skills and education as important components of the future of gardening and horticulture (RHS, 2025a).
17. Gardens and Wellbeing
The social value of gardens extends beyond gardening itself.
Outdoor spaces can provide opportunities for movement, contact with nature, social interaction and creative activity.
A garden can be designed to encourage different levels of participation.
Someone might grow vegetables.
Another person might sit beneath a tree.
Someone else might observe insects or birds.
A child might explore soil and plants.
A group might work together on a community growing project.
The value of a garden therefore cannot be measured solely by its appearance.
Its value also lies in what people are able to do, experience and learn within it.
18. Technology and Observation
Technology will increasingly influence garden management.
Sensors can measure:
- soil moisture;
- temperature;
- humidity;
- light;
- rainfall; and
- other environmental conditions.
Digital mapping can help gardeners understand variations across a site.
Weather information can inform irrigation and planting decisions.
Plant databases can provide information about species and cultivars.
However, technology should support rather than replace observation.
A moisture sensor can report that soil is dry.
The gardener still needs to decide whether watering is appropriate.
The future gardener will therefore need both digital literacy and horticultural judgement.
19. Gardens as Living Laboratories
Gardens provide opportunities for observation over long periods.
Gardeners can record:
- flowering dates;
- first and last frosts;
- pest activity;
- disease outbreaks;
- bird and insect visits;
- plant survival;
- drought effects; and
- changes in seasonal behaviour.
When observations are collected systematically, they can contribute to broader understanding of environmental change.
This creates a useful relationship between practical horticulture and scientific research.
The gardener becomes an observer of ecological change.
20. The Garden as Shared Infrastructure
The combined area of gardens can represent a significant part of the landscape.
Individually, a small garden may appear insignificant.
Collectively, gardens can provide:
- habitat;
- vegetation corridors;
- water management;
- shade;
- cooling;
- food production;
- carbon storage;
- recreational space; and
- opportunities for social connection.
This changes the way gardens can be understood.
A garden is not necessarily an isolated piece of land.
It can form part of a wider green infrastructure network.
The RHS identifies gardens as an important resource for biodiversity, climate adaptation and human wellbeing (RHS, 2025a; RHS, 2025b).
21. Designing the Future Garden
A future-oriented garden can be assessed through five questions.
1. Can it cope with environmental change?
Consider heat, drought, intense rainfall, wind and changing seasons.
2. Does it support life?
Consider plants, insects, birds, fungi, soil organisms and other wildlife.
3. Does it use resources responsibly?
Consider water, soil, materials, energy, fertilisers and pesticides.
4. Can different people use it?
Consider physical access, sensory experience, cost and cultural inclusion.
5. Can it adapt?
Consider whether planting, infrastructure and management can change as conditions change.
These questions provide a practical framework without prescribing a single style of garden.
Conclusion
The garden of the future will be shaped by environmental and social change.
Climate science indicates that gardeners will increasingly need to plan for higher temperatures, periods of water scarcity, intense rainfall and greater climatic uncertainty. Plant selection, soil management and water use will consequently become important parts of climate adaptation.
Biodiversity will also be central. Diverse planting and varied habitats can support wildlife and increase the range of ecological functions provided by a garden.
At the same time, gardens are human spaces. Their future must consider who has access to them, who participates in their design and management, and whether people with different physical, sensory, cultural and economic circumstances can benefit from them.
This creates a broader definition of successful gardening.
A successful future garden may be one that:
supports biodiversity,
uses resources carefully,
manages water,
protects and builds healthy soil,
adapts to climatic uncertainty,
provides meaningful opportunities for people,
and
forms part of a wider network of living spaces.
The future of gardening is therefore not simply about finding plants that survive a warmer climate.
It is about creating places where plants, wildlife, soil, water and people can interact successfully in a changing world.
