How to Identify Japanese knotweed

When it comes to Japanese Knotweed identification, the different seasons throughout the year have a large part to play.

Japanese knotweed growth is usually at its most prolific from April to October, but mild winters and warm damp summers in recent years have seen the growing season extended. Early signs of growth are now seen in mid-March and new shoots have even been identified as late as November. This is why Japanese knotweed treatment or removal programmes often have to be reviewed annually to ensure the methods being used will continue to be effective.
