Experts reveal the everyday garden habits that annoy neighbours the most – and the simple ways to avoid causing complaints

Not every neighbour dispute starts with a major landscaping project - more often than not, it's the everyday garden habits that annoy neighbours. From mowing the lawn at the crack of dawn and letting hedges creep over the fence to installing outdoor lighting that shines into your neighbour's garden, small oversights can quickly become recurring irritations.

While these habits are rarely intentional, repeated noise, neglected planting and poorly positioned lighting can all create tension and build up over time. The good news is that most of these issues are easy to avoid with a little forward planning and regular maintenance.

Just as there are certain garden features that can cause disputes, the way you use and maintain your outdoor space can be just as important. To help you avoid the biggest neighbourly bugbears, we asked gardening and property experts to reveal the issues most likely to cause complaints, and what you can do to keep the peace.

1. Letting hedges and trees take over boundaries

'The biggest causes of neighbour disputes are usually plants that cross boundaries or start affecting how someone else can use their garden,' explains Liam Cleary, gardening expert at Old Railway Line Garden Centre.

Overgrown hedges are also a common issue when they begin blocking light, taking up too much space or becoming difficult to maintain. 'Trees that grow too large for their original position, drop excessive leaves or have roots affecting nearby areas can also become a source of frustration for those nearby,' adds Liam.

While it might be tempting to cut back your neighbour's hedges that extend across a boundary, there are some rules worth knowing first, as you could even be breaking the law in your own back garden. 'You have the legal right to prune branches or roots back to the boundary line; however, you should not step onto your neighbour's land without their permission while doing so, as this can be classed as trespassing,' warns Richard Barker, horticultural expert at LBS Horticulture.

The plant material cut off technically belongs to the plant's owner, so once trimmed, you should offer them back to your neighbour. 'If they do not want these, you are responsible for disposing of them and cannot throw them back over the fence,' adds Richard.

2. Allowing fast-growing climbers to run wild

Climbing plant ideas can add plenty of character to a garden, but when they're not kept under control, they can quickly become a source of tension between neighbours.

'Climbing plants can cause problems when they're not kept under control, especially if they start spreading onto fences or outbuildings that don't belong to the homeowner who planted them,' says Liam.

Fast-growing climbers, like ivy or wisteria, can cause issues if left unchecked. 'They can cling to brickwork, block guttering and spread under roof tiles, causing costly structural damage to shared walls,' warns Richard.

So what can you do if a climbing plant starts crossing a boundary? 'You're allowed to prune any part of a climbing plant that crosses your boundary line,' explains Richard. 'If plants have caused significant damage, your neighbour may be liable for the repair costs.'

Prevention is often the easiest solution. 'Fast-growing plants, self-seeding varieties and bamboo are also worth keeping an eye on because they can quickly spread beyond where they were originally planted,' adds Liam. Regularly checking growth and training climbers onto the structure they're intended to cover can help prevent problems developing.

3. Letting your garden become untidy

While a garden doesn't need to be tended to daily, a messy garden is among the garden habits that annoy neighbours.

'Garden maintenance can become a point of tension when lawns, borders or planting areas are left unmanaged for long periods,' says Liam. 'Issues such as weeds spreading through seeds, plants growing through fencing, branches hanging into neighbouring gardens and garden waste accumulating along boundaries can all create avoidable problems.'

The good news is that keeping on top of the basics can prevent most issues from escalating. 'With weeds, prevention is usually easier than removal,' adds Liam. This involves keeping borders covered with mulch and removing weeds before they set seed, which can help reduce the chance of them spreading.

'A tidy garden doesn't need to be perfectly maintained, but it does need some basic upkeep to stop plants becoming someone else's problem,' Liam says.

That said, it's worth approaching the situation with understanding. Richard recommends having a conversation with your neighbour in the first instance: 'A neglected garden can be the result of someone being physically unable to cope with the upkeep required, and they may need help.'

Rather than making the conversation about the state of their garden, focusing on the impact - such as plants spreading or damage to shared boundaries - can help keep things neighbourly.

4. Hosting loud garden parties or making noise at antisocial hours

We naturally spend more time in our gardens during summer, but with neighbours also enjoying their gardens and keeping windows open, noise can travel much further than you might expect.

'Beyond the visual, it is the behavioural habits that can be harder to address but just as damaging,' says Katie Cromwell, founder and director of No. 86 Estate Agency in Swansea. 'Loud parties, regular late-night gatherings or persistent noisy DIY at weekends create a reputation for a property that buyers can pick up on.'

Whether it's mowing the lawn, using a pressure washer at the crack of dawn or hosting a late-night BBQ, being mindful of the time can go a long way towards keeping the peace. If you are planning a larger gathering, giving neighbours a quick heads-up beforehand is a simple gesture that's often appreciated.

5. Watering your garden without thinking about next-door

It might not be the first thing you think of, but where your sprinkler or hose is pointing can affect more than your own garden. Sprinklers that spray over the fence, or hoses that repeatedly soak shared boundaries, can create problems with neighbouring gardens without even realising it.

'If your neighbour's garden watering is leading to an excessive amount of runoff or overspray, this can cause problems in your own garden, such as oversaturated soil, root rot and fungal diseases,' says Richard.

If your garden is at a lower level than your neighbours, excess water can naturally pool on your property and drown plants.

Repeatedly soaking a shared fence can cause damage, too. 'If they are soaking the fence when watering, this can make the wood rot and encourage mould growth,' adds Richard. 'You should begin by talking to them about redirecting their hose or adjusting their sprinklers so it does not affect your garden or fencing.'

6. Installing outdoor lighting that shines into neighbours' homes

If you're wondering whether neighbours can complain about outside lighting, the answer is unfortunately yes. Security and feature lighting is increasingly common, but poorly positioned fixtures can quickly become a sore point.

'Harsh, poorly positioned security lighting that floods a neighbour's garden is something buyers notice and ask about, particularly in the evening,' says Katie. 'It suggests an unresolved tension that they may inherit.'

Luckily, the fix is straightforward and low-cost. 'Replace directional security lights with motion-activated alternatives that are angled inward rather than outward. It costs very little and removes a potential source of dispute,' advises Katie.

7. Leaving bins or garden waste where they affect neighbours

First impressions count, and bins are often the first thing a neighbour or visitor will see. If you've ever wondered whether neighbours can leave their bins outside your house, you're not alone - where bins are stored between collections can also become a common source of frustration.

Katie says this is a bigger factor than most homeowners realise. 'Bins left permanently on display at the front affect first impressions before anyone has even knocked on the door.'

Katie's advice is simple. 'Move them out of sight where possible, and look at whether a bin store can be added permanently. Even a simple wooden screen makes a significant difference to how the front of a property presents.'

The same logic applies to garden waste left along a shared boundary, which Liam flags as an avoidable source of tension if it's allowed to build up over time. Garden maintenance can become a point of tension when lawns, borders or planting areas are left unmanaged for long periods,' he says. 'The best approach is to check your garden regularly.'
