If you are a keen gardener in the UK, you will likely be familiar with some of the invasive species that are damaging the habitats of our native ones. This is something that receives a fair bit of attention in the press, as well as on programmes such as Countryfile. One such rogue plant is the Japanese Knotweed, which is now said to occupy a site in every 10km of England and Wales, and is also present in Scotland [1].<\/p>\n
This invasive species is causing problems to homeowners and businesses throughout the United Kingdom, especially in regards to structures such as concrete, tarmac, brick walls and foundations. The issue with Japanese Knotweed is the rate that it has spread, and the destruction to well cultivated gardens and even buildings.<\/p>\n
Here are some of the specific problems caused by Japanese Knotweed [1]:<\/p>\n
- \n
- \n
Damage to paving and tarmac areas<\/p>\n<\/li>\n
- \n
Damage to retaining wall structures<\/p>\n<\/li>\n
- \n
Damage to building foundations<\/p>\n<\/li>\n
- \n
Damage to flood defence structures<\/p>\n<\/li>\n
- \n
Damage to archaeological sites<\/p>\n<\/li>\n
- \n
Reduction in land values<\/p>\n<\/li>\n
- \n
Aesthetic issues<\/p>\n<\/li>\n
- \n
Reduction in biodiversity through out-shading native vegetation<\/p>\n<\/li>\n
- \n
Many insects \/ wildlife that are dependent on our native plants are lost or in danger<\/p>\n<\/li>\n<\/ul>\n
Some of these will be more relevant to you as a gardener, such as damage to paving, aesthetic issues and reduction in biodiversity. In rare cases, some would-be homebuyers have been refused a mortgage for properties when this plant is present, so it is something to watch out for in the future too.<\/span><\/p>\n
