Hedges need your commitment to regular hedge cutting / trimming.

You can avoid a lot of problems in future if you choose the right hedging plants for your boundary.
Hedge planting - the right choice.
The many benefits of growing hedges on your boundary depend on selecting the right plants for the situation. If you choose an unsuitable variety you could be faced with a range of problems, especially if the hedge grows too big. It will be difficult to trim and may cut out light to your garden or house.
Its roots could deprive other plants of water and nutrients, and even interfere with paths and buildings.
Oversize hedges will intrude on your garden space, and may cause problems with neighbours.
Oversize hedges can be costly and time consuming to cut back and most conifers, including Leyland and Lawson's cypress, will not tolerate hard pruning.
If the hedge borders a road or path the local authority could get involved, and insist the hedge is cut back.
Luckily there is a wide range of plants available so it's not difficult to achieve an attractive healthy hedge - one which will take only as much upkeep as you can manage, and create an attractive feature in your neighbourhood, not a bone of contention.
