Research areas at RHS Science

Based at RHS Hilltop, the UK’s first dedicated research centre for gardening science at RHS Wisley, our science teams are carrying out pioneering research to combat global challenges such as the climate, biodiversity and health crises, promote sustainability in horticulture, and help improve the health of the environment, people and nature

RHS Science Strategy

From 2020-2025, we’ve been focussing our scientific work on garden plants: their diversity, their health and their effect on people’s wellbeing.

This five-year RHS Science Strategy focuses on ensuring that the UK’s 27 million gardeners have the tools they need to address the horticultural and societal challenges they face now and in the future.
