Japanese knotweed and other invasive plants have become a common sight in the East of England since their introduction in the 19th century, colonising our gardens, parks, verges, countryside and waterways. Japanese knotweed is the most problematic, but other plants such as bamboo, horsetail, giant hogweed, Himalayan balsam and cotoneaster can also cause considerable problems. 

Knotweed is found throughout the region, most often in built-up areas such as Norwich, Ipswich and Cambridge, as well as coastal areas including around Great Yarmouth and parts of the North Norfolk coast.

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.

If you’re looking for the best in invasive plant removal in the East of England, call Environet today to speak with our dedicated, highly experienced team. We’re able to offer our customers the benefit of working with a market-leading, specialist company, that prides itself on a personalised, local service.
