Japanese knotweed and other invasive plants have become a common sight in London since their introduction in the 19th century, colonising the city’s gardens and parks, verges and waterways. Japanese knotweed is the most problematic, closely followed by bamboo which has become increasingly popular in recent years due to its screening qualities but will spread rampantly if left unchecked. Other invasive plants such as horsetail, giant hogweed, Himalayan balsam and cotoneaster can also cause considerable problems. 

Knotweed now grows rampantly throughout the capital, with particular hotspots around Clapham and Wandsworth, Croydon, Ealing, Hackney and Camden.

Japanese knotweed can damage property, lead to expensive repairs and spread to neighbouring properties, creating complicated legal issues. It can even cause home values to plummet and make them difficult to sell. We have successfully helped hundreds of homeowners across the region overcome problems that Japanese knotweed has caused on their properties.

Bamboo also spreads, its rhizomes extending 30 feet or more, with new shoots appearing through lawns and patios. Where this occurs in an adjacent property it can result in neighbour disputes which can ultimately lead to legal action.
