Sustainability in Garden Design
Materials
Minimise hard surface coverage, especially when it is impermeable
Use reclaimed or recycled materials and materials from renewable sources
Exclude unsustainable materials such as fake grass (astroturf) and tropical timber unless reclaimed
Reduce the movement of materials on and off site, to minimise transport and waste disposal
Water
Contain and manage as much water within the site as possible, by way of rain gardens, pools, swales and soakaways
Minimise fresh water use as much as possible, using stored rainwater for watering plants
Include still water for nature wherever possible
Planting
Choose species that provide varied habitats and food sources to support a range of wildlife
Choose lower-maintenance species resilient to the growing effects of climate change
Choose plants with a range of functions to minimise the effects of extreme weather events
Plant at the right times of year to reduce losses
Plant from smaller pots wherever possible, and use bare root perennials and seed mixes when appropriate to reduce transportation and plastic waste
Soil
Reduce soil disturbance to an absolute minimum because soil excavation releases carbon
Protect the soil with ground cover plants and mulches when needed
Release ‘trapped’ soil from underneath existing sealed surfaces like paving
Grow your own food, reducing the pressure on the wider landscape
Biodiversity
Create habitats for wildlife - the possibilities are endless
Change the way we think about lawns - include flowering and species-rich lawns and let areas of lawn grow long throughout the year, reducing maintenance
Plant a wide variety of species, and as many as the brief allows
Keep garden lighting minimal, subtle or non-existent - nature needs night
Education
Share your enjoyment of your outside space with everyone you know, especially those with little or no access to a garden
Make spaces for children to learn and play freely within the landscape, not protected from it
Share your knowledge of sustainable garden practices with anyone who will listen
