Seasonal news

Japanese knotweed is an invasive plant that is damaging our wildlife and property. It starts to re-grow during the Spring, following a dormant period during the Winter months, and can grow up to 10cm a day. It spreads extremely quickly, and is a problem to the construction industry as it is capable of exposing weaknesses in buildings, foundations, concrete and tarmac.

It is a lush green colour, with heart shaped leaves. The stems are bamboo-like in appearance, and it produces white flowers during September or October. The stems can reach 3m high, and roots and rhizomes can grow up to 7m away from the visible stems.

Thomson Habitats treat and control invasive species, including Japanese knotweed, by using the most suitable method, including spraying, cutting down the stems and crowns, and using an excavator to “turn over” the ground. We hold a waste transfer licence, which means that we are able to remove the rhizomes from your site and dispose of them in a safe and controlled way.
