If the summer of 2026 was unusually hot and dry in England, as it was in many other regions around the world, experts are now preparing for such conditions to become more common in the years ahead. Scientists attribute this trend to global climate change, largely driven by human activities such as burning fossil fuels, which increase the concentration of greenhouse gases in the atmosphere. These gases trap heat, leading to rising global temperatures and more frequent extreme weather events, including prolonged droughts and heatwaves. In response to these challenges, the Royal Horticultural Society (RHS) has been working to adapt its gardens to the changing climate. One of its key projects is located at the RHS Wisley garden in the south of England, a renowned center for horticultural research and display. Here, gardeners and scientists are experimenting with new ways to maintain plant life in increasingly hot and dry conditions. This includes the use of drought-resistant plant species and improved irrigation techniques that use water more efficiently. A significant part of the adaptation strategy involves duplicating the garden’s plant collections. By creating multiple copies of each plant, the RHS ensures that if one collection is damaged by extreme weather or disease, another can quickly replace it. This strategy not only helps preserve the diversity of plants on display but also supports ongoing research into which species can thrive under future climate conditions. It also allows the garden to continue its role as a resource for both the public and horticultural professionals. The efforts at RHS Wisley are part of a broader movement among gardeners and environmental scientists to prepare for a warmer and drier future. As climate change continues to reshape the environment, such initiatives are becoming increasingly important in maintaining biodiversity and ensuring that green spaces can continue to flourish. By adapting now, these gardens are helping to build resilience against the unpredictable challenges of a changing climate.
