Eight of the best defensive plants to keep thieves out of your garden

With summer burglaries on the rise, homeowners are being encouraged to implement a natural and eco-friendly method to bolster their garden security, with dense, spiky plants.

Garden experts at GardenBuildingsDirect.co.uk have shared eight of the best defensive plants that create natural barriers to deter intruders.

With summer in full swing and millions of Britons away on their summer holidays, it’s important to ensure gardens are secure while properties are left unattended, with burglaries in the UK typically increasing by up to 25% in July and August.

Bicycles, garden furniture, and even metal – which is sought out by criminals for its high scrap value – are amongst the most common items stolen from gardens.

To deter potential thieves, homeowners are encouraged to make their gardens as difficult to access as possible.

Security systems such as CCTV and motion sensor lighting, high-quality shed locks, and even gravel pathways can all help towards deterring potential theft.

But for those looking for a natural, eco-friendly security barrier, defensive planting is highly recommended too.

Dense hedging and prickly plants, such as species like hawthorn, holly and mahonia, all act as excellent deterrents against intruders while also providing habitats for wildlife.

Experts do warn against laying traps such as coils of barbed wire on the ground, however. These would give rise to injury claims, even in the context of trespassers, as they could harm innocent people or animals.

A spokesperson for GardenBuildingsDirect.co.uk said: “A few well-placed thorny plants can be as effective as any security measure, and much better looking too.

“Defensive planting is one of the most natural and low-cost ways you can secure your garden, while giving wildlife a home.

“With a bit of strategic positioning along garden boundaries, under windows, or near potential access points, you can create a barrier that’s both visually appealing and a burglar’s worst nightmare.”

Eight of the best security plants for your garden:

Hawthorn 

Thanks to their dense, thorny branches, Hawthorn hedge plants are excellent intruder deterrents and difficult to penetrate. They also provide a year-round habitat for wildlife.

Blackthorn

Blackthorn is dense with thorny branches, which makes it extremely tough to get through and a very effective barrier against humans and animals trying to cross property lines.

Holly

Holly forms an excellent barrier and privacy screen. With its evergreen, sharp, spiny-edged leaves, it can deter both animals and potential thieves.

Pyracantha

With long, needle-sharp thorns on its dense branches, Pyracantha is excellent for a trellis or wall, making it a formidable deterrent against intruders.

Berberis

A good choice for boundary planting and preventing unwanted access due to its dense, thorny growth, which makes it difficult to push through.

Rose

With stems armed with thorns, roses planted densely can create a difficult barrier, while climbing roses are perfect for a trellis, making a painful deterrent over fences and around gates.

Gorse

Its dense, vicious spines make it almost impossible to pass through, making for an excellent security barrier. As well as a physical deterrent, gorse is also a wildlife-friendly habitat.

Mahonia

With sharp, spiky leaves, and a habit of growing densely, Mahonia shrubs create thick barriers that make it difficult for intruders to penetrate.
