Supported by the Bumblebee Conservation Trust, the RHS is calling on all members of the public to observe bumblebee sightings on flowers in gardens and parks across the UK – from the 12th of February until 31st of May 2024, and record their findings and photographs.

Bumblebees are a vital group of wild pollinators, helping to pollinate our garden plants as well as much relied on crops such as apples, tomatoes, and peas. When the weather starts to warm, queen bumblebees emerge from hibernation seeking flowers to provide nectar as fuel for flight and protein-rich pollen to feed the developing larvae of the worker bees.

The duel challenges of habitat loss1 and climate change mean that the availability of flowers in springtime is critically important for helping bumblebees establish successful colonies at the start of the season.

Data gathered during this project will help boost bumblebee populations by ensuring that gardeners receive the best advice for what to plant, and improve our understanding of their habits. Wildlife specialists from the RHS will monitor the results that could also provide valuable insight into whether factors such as flower colour and how urban or rural a site is influence bumblebees’ plant choice.

Helen Bostock, RHS Senior Wildlife Specialist said: ‘Bumblebees are a vital part of our ecosystem, pollinating our crops and flowers, and playing a key role in much of the food we eat. In the face of large-scale changes to the countryside and the ensuing decline in their numbers, flowers in gardens and parks are an increasingly important source of pollen and nectar for bumblebees. This project is an opportunity to give back; the better we understand which plants these industrious insects most rely on, the more we can help them to thrive.”
