Overgrown gardens
What to do about a neighbour's overgrown garden
Overhanging vegetation from overgrown gardens can be cut off by the affected property owner to the boundary line and passed back to the overgrown side; however, you should talk with your neighbour first to discuss any issues and try to find a suitable resolution before cutting back vegetation.
It may be that your neighbour is having difficulty coping with the garden and would appreciate some support, maybe from yourself or perhaps from local charities or volunteer groups.
Damage caused by overgrown vegetation (such as damage to boundary fences) is a civil matter and you should seek independent legal advice if this is the case. The Council is unable to assist in these matters.
