You may or may not have heard of Japanese Knotweed. Its large root system and ability to grow through 3-4 inches of concrete or brick makes it vastly unpopular with surveyors when it comes to selling or letting your property, so it’s always good to know what to look out for so you can have it dealt with before it becomes too big of a problem.

The plant which causes a lot of problems for sellers and landlords alike was originally introduced to the UK in about 1825 when it was planted in Chiswick botanical gardens. It became a lot more popular 20 years later when it won an award in Holland, and it was planted in more and more gardens.

Knotweed is a perennial root, and is spread by cuttings from the root system. Since the 1800s, the movement of soil has increased with more and more construction taking place, and soil taken from areas where Japanese Knotweed was already growing has meant the spread of the plant without anyone really noticing.
