Japanese knotweed will flourish on any soil - no matter how poor or infertile, it is these characteristics that have caused many property owners, so many headaches. The good news is that there are several professional methods of Japanese knotweed removal that have proven to be very successful. Knotweed services UK offer many of these treatments.

Japanese knotweed – the problem

The problem and nuisance of Japanese knotweed has become much more wide spread in recent years.

It is now so wide spread and common, that mortgage providers are now very aware of the threat that Japanese knotweed poses.

What this means is that Japanese knotweed can affect either the purchase or sale of a house!

Experts have estimated it costs the UK £166 million annually. It is even estimated that in the UK, there is at least 1 infestation in every 6 miles squared.

The requirement of a Japanese knotweed removal service has never been greater. It is important to state that although you are not legally obliged to remove Japanese knotweed, if you are a land or home owner it is an offence to cause it to spread to neighbouring properties or land - so if you have Japanese knotweed and do not opt for a Japanese knotweed removal service and it then spreads - you will legally be liable.

Japanese knotweed and the law

Awareness of Japanese Knotweed (Fallopia Japonica) in the UK has become significantly widespread in recent years. In part, this is a result of the increased growth and impact of Japanese knotweed.

It is also due to the role that media attention has had to play in raising the public's awareness. The ease that Japanese Knotweed is spread, the alarming degree of its subterranean rhizome system and the incredible destruction it may cause are well acknowledged in environmental groups. However, less appreciated and understood by the general public are the potential legal implications that a Japanese Knotweed infestation brings with it.
