Japanese knotweed in garden found during building survey.


From the stunning White Cliffs of Dover to the rugged peaks of the Scottish Highlands, the United Kingdom is a land blessed with an incredible diversity of flora. However, amidst this splendid diversity, a sinister problem looms large – invasive plant species. These plant invaders, with their aggressive growth and reproduction, pose a significant threat to the native ecosystems. Today, we’ll delve into three of the most notorious culprits: Japanese knotweed, giant hogweed, and horsetail.

Three of the UK’s Invasive Plant Species

In the diverse landscape of the UK, from iconic landmarks like the White Cliffs of Dover to the picturesque Scottish Highlands, there’s an escalating concern for homeowners and environmentalists alike: invasive plant species. These aggressive invaders, capable of endangering native ecosystems and posing threats to building structures, are a critical aspect that building survey reports address. Today, on www.flettons.com, let’s dive deep into three prevalent culprits: Japanese knotweed, giant hogweed, and horsetail, and why a building survey report can save you from potential property pitfalls.

Japanese Knotweed: A Homeowner’s Nightmare

Introduced in the UK during the 19th century as an ornamental delight, Japanese knotweed (Fallopia japonica) soon turned into an architectural adversary. Its intrusive root system threatens building foundations, pathways, and infrastructures. While it’s a menace for native flora, its potential damage to homes makes a building survey report essential before property transactions. Addressing it requires persistence and often chemical interventions, with newer biological control methods showing promise.

Giant Hogweed: Beauty with a Bite

Giant hogweed (Heracleum mantegazzianum) stands tall, reaching heights of over 5 meters, making a statement in gardens. However, its sap is detrimental to human health, causing phytophotodermatitis. A thorough building survey report identifies such threats, ensuring potential homeowners are aware of the dangers lurking in their backyards.

Horsetail: The Deep-rooted Issue

Horsetail (Equisetum), with its expansive history, is notorious for its widespread growth in varied soil conditions. Its extensive root system, stretching up to 2 meters deep, poses challenges for eradication. While it’s an ecological concern, understanding its presence and potential harm is crucial, reinforcing the importance of a detailed building survey.
