Young Japanese knotweed shoots are typically brown with specs of dark green
Knotweed appears to ‘die back’ during winter, but it’s unwise to assume that the problem is simply gone. In the middle of winter, all that remains above ground is a collection of pale, dry canes with the Japanese knotweed dormant beneath the surface waiting for warm weather to sprout and spread further. Whilst the plant enters this dormant phase it is still very much alive.
When is the Best Time to Identify Japanese Knotweed?
Once spring is well and truly underway, shoots take on a greener hue and become easier to spot due to their accelerated growth . Now growing as spear-shaped shoots, sometimes described as ‘asparagus-like, the leaves are red and rolled up, but they soon turn green as the plant grows skyward.
Japanese knotweed flowers bloom in small clusters
Japanese knotweed has heart-shaped seeds that feature small wings. New growth from seeds is very rare , as only the female of the species was imported into the UK. For the most part, Japanese knotweed has been spread throughout the country by the transportation or fragmentation of its rhizomes. The rhizomes are effectively the plant’s root systems, with a fragment of the rhizome capable of generating an entirely new plant if given the proper conditions. Unfortunately, Japanese knotweed has been observed to hybridise with other related species  which has led to new plants that are able to then spread by seed down the line.
