I sometimes get complaints or questions about what the Council can do when a neighbour allows their garden to become completely overgrown with brambles and possibly harbouring rats.
The Council can sometimes help if there is a significant environmental health issue.
They have certain powers under the Town and Country Act.
However, what they can do is quite limited a lot of the time.
You cannot compel people to become tidy gardeners.
It is their land. Opinions differ as to what a good garden is.
Some people like it being a haven for wildlife.
The best thing is to share your concerns with the Environmental Health Department at NFDC.
They will normally investigate and see what might be reasonably done.
