There are over 600 thousand RHS members and 42 million people who garden in the UK. Imagine what a difference we could make to the environment together.
“We are now painfully aware that we face a climate and biodiversity crisis, and that every effort counts. The RHS is in a unique position to harness its science, reputation and reach to help address this in a positive way.”
Gardens can provide vital support for wildlife. Through the plants we choose and how we manage our spaces, we can all help tackle biodiversity loss.
Alongside creating habitats and gardening in wildlife‑friendly ways, it’s important to prevent the spread of pests and diseases that can harm gardens, trees and food crops across the UK. This is known as biosecurity.
Many everyday gardening choices have climate impacts, from what we buy to how we design and manage our spaces.
The materials we use, the energy we rely on, and decisions about paving, planting trees, fencing and hedging all affect carbon emissions and local climate conditions.
Water is essential for life, but climate change is bringing hotter temperatures, longer droughts and heavier rainfall.
To help biodiversity cope with these extremes and reduce pollution that threatens environmental and human health, we need to rethink how we use and manage water in our gardens.
