Hillingdon in Bloom

A free competition that encourages local gardeners to improve their environment through the imaginative use of flowers, trees, shrubs and landscaping.


In recent years the popularity of Hillingdon in Bloom has grown considerably, with amateur gardeners from all parts of the borough taking part throughout the summer months. From large front gardens to the smallest of window boxes, residents or businesses in the borough can take part.

As part of Britain in Bloom there will be an initiative that Hillingdon will take part in for three years called Greener Streets: Better lives, in an effort to 'green up' our grey spaces, such as streets and high streets.

Greener Streets is a Royal Horticultural Society Britain in Bloom initiative. By adding plants, we aim to transform these often dull and uninspiring areas to beautiful green spaces and improve the quality of lives of residents, business owners and visitors.

Our Green Spaces team will be happy to help with any gardening advice you may need, including your green streets ideas. Please email contact@hillingdon.gov.uk or call 01895556000. 

The council will also be providing, on application, financial grants of up to £1,000 for gardening materials to help residents and community groups to take part in the Green Streets initiative.
