Japanese Knotweed Management Plan
What is Japanese knotweed?
Described by the Environment Agency as “indisputably the UK’s most aggressive and invasive plant”, Japanese knotweed has become the scourge of home and land owners, sprouting up in gardens, building sites and wildlife areas around the country. The pervasive weed has the potential to grow and spread at rapid rates.
Originating is Asia, Japanese knotweed was brought to the UK in the 1850’s for planting in botanical gardens. Its intent was not problematic at first because the bamboo-like appearance made it a favourite of gardeners. However, they soon realized that it had the ability to grow anywhere and everywhere at a very rapid rate. This aspect of Japanese knotweed became very problematic over time.
The troublesome plant puts wildlife at a risk, killing off any plants in its surrounding area. Japanese knotweed is strong enough to penetrate through weaknesses in concrete and tarmac, inflicting costly damage on the walls and foundations of buildings. The discovery of Japanese knotweed has led to mortgages and planning permissions being rejected, drastically reducing the value of the land if it’s not properly taken care of.
