Japanese knotweed and various invasive plants have become a widespread presence throughout Wales since their introduction in the 19th century, establishing themselves in our gardens, parks, verges, and waterways. The origins of knotweed sightings near Wales’ main ports are believed to be linked to historical shipping and trading practices lacking in biosecurity. In the 19th and 20th centuries, ships returning to the UK from various parts of the world often carried ballast, including soil from foreign ports, which was then discarded to make room for the next cargo.
Among the invasive plants, Japanese knotweed poses the most significant challenge, closely trailed by Bamboo, which has gained popularity in recent years for its screening qualities but can proliferate unchecked. Other problematic species include Horsetail, Giant hogweed, Himalayan balsam, and Cotoneaster.
Knotweed is now prevalent throughout Wales, with notable concentrations in Conwy, Llanelli, Caerphilly, Swansea, and Bridgend.
The unwanted presence of Japanese knotweed has the potential to cause property damage, which means costly repairs, and its potential to spread to neighbouring properties can also cause complex legal issues. It can even lead to a depreciation in home values, making them challenging to sell.
Our team has successfully assisted hundreds of homeowners across the region in addressing issues caused by Japanese knotweed on their properties.
As invasive as Japanese knotweed, Bamboo, with its rhizomes extending 30 feet or more, spreads rapidly, causing new shoots to emerge through lawns and patios. When this encroachment affects neighbouring properties, it can lead to disputes among neighbours, potentially resulting in legal action.

We had a reservation on one of our developments where the customer was extremely nervous about historic Japanese knotweed. With help from Environet, including their treatment and a 5 year insurance backed guarantee, we were able to secure knotweed indemnity insurance. Thank you to Environet!
