What is Japanese Knotweed?

Japanese knotweed is a fast-growing, invasive weed, It is rapidly becoming one of Britain’s most invasive weeds. Japanese Knotweed can remain dormant for over twenty years, but once it begins to grow, it can spread at a pace of 1.2 metres per month and up to a whopping 10cm a day. It develops a series of underground roots and shoots, referred to as rhizomes, which can grow out for several metres from the original stand. It is characteristic by its hollow, purple stems and heart-shaped leaves. If you need more information on this, we have a page dedicated to helping our clients to identify Japanese knotweed.

Why Should I Attend Your CPD Course?
