What is Japanese Knotweed?
Japanese knotweed is a fast-growing, invasive weed. It is relatively attractive to the eye and especially attractive to insects. Japanese knotweed can remain dormant for over twenty years, but once it begins to grow, it can spread at a length of 1.2 metres per month. 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 would like to know what Japanese Knotweed looks like in the Winter, carry on reading!
