Is Japanese Knotweed Growing on My Property?

Updated: May 12, 2023

During Spring, we receive many calls from clients and members of the public who are struggling to sell their land or their homes due to the presence of Japanese Knotweed.

What is Japanese Knotweed? Is it really that bad?

Japanese Knotweed is an exceptionally aggressive, invasive plant, capable of weakening concrete, tarmac, brick walls and foundations. Left untreated, it can cause serious structural damage, proliferate rapidly and create a legal liability that is now making many mortgage lenders increasingly reluctant to lend on properties where Japanese Knotweed is present.

What should I do if I think it's on my property?
