As the days lengthen and temperatures rise, encouraging people outdoors, numerous gardening enthusiasts across Britain are focusing on their outdoor spaces. A thriving garden can be a genuine source of pride - but certain widely grown plants in the UK could actually be causing significant harm to your property.
Without proper maintenance, these plants may penetrate walls and drainage systems - and they might even jeopardise your insurance coverage. Specialists at Norton Insurance Brokers have highlighted apparently harmless garden staples that can result in expensive repairs, rejected insurance claims and legal battles when left unmanaged.
Despite their attractive and delightful appearance, understanding the potential hazards is crucial.
Wisteria
This plant is breathtaking. It's a climbing species, frequently adorned with cascading purple flowers. Nevertheless, it can spread vigorously and produce substantial, woody stems that wind around whatever lies in their way.
As these stems develop, they can exert force on walls and guttering, progressively expanding cracks. Left to flourish without control, wisteria may even shift roof tiles or guttering. Should you make the error of positioning wisteria too near your home, it can also compromise foundations and drainage systems.
Bamboo
While it may appear attractive, bamboo represents one of the most significant threats to properties and gardens when not properly controlled. Its subterranean root system spreads with remarkable aggression, frequently extending several metres from its initial planting location. The emerging shoots are capable of displacing paving slabs, damaging driveways and penetrating gaps in building foundations.
Japanese knotweed
The troublesome nature of Japanese Knotweed is widely recognised; indeed, eradicating it once it's taken hold is virtually impossible. The plant is notorious for its rapid proliferation and capacity to exploit vulnerabilities in constructed features. It can penetrate gaps in paving, masonry and drainage infrastructure, and homeowners attempting to sell their property may be required to declare its presence in the garden prior to completion.
English Ivy
It's a quintessentially British image - a brick cottage adorned with climbing ivy. However, this picturesque scene conceals a potential hazard. Ivy is infamous for harming the surfaces it attaches to due to its powerful aerial roots. These roots penetrate fissures and mortar joints, widening vulnerable areas, potentially resulting in moisture penetration and structural deterioration.
Jasmine
Prized for its delicate blooms and enchanting fragrance, this climbing plant can inflict harm when not properly managed. During summer months, jasmine can create a dense green covering that conceals underlying structural issues. When brickwork is already deteriorated or damaged, this sustained moisture contact can result in damp issues, particularly in period properties. Jasmine may also block gutters, downpipes, vents, or air bricks, restricting ventilation and establishing perfect conditions for water penetration and mould growth.
