Hillingdon in Bloom

Seasoned enthusiasts and 'greener' novices from across the borough are invited to enter this year's Hillingdon in Bloom.


The free-to-enter competition encourages local gardeners to get creative with imaginative use of flowers, trees, shrubs and landscaping and there are 12 categories, ranging from window boxes and balconies, to front gardens and communal spaces.

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. It's the competition that makes our borough so blooming marvellous! 

The deadline for entries has now closed.

Britain in Bloom

Hillingdon was success in the national Britain in Bloom awards, winning gold for the "large city" category in 2017. The borough also has the most Green Flag parks in the United Kingdom (49).

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.

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.
