So what does Japanese knotweed look like? Like any plant Japanese Knotweed looks different depending on the time of year. Typically the growing season is from April to October, however mild winters and damp summers have extended the growing season from as early as mid-March to as late as November. This means that there is more time for the Japanese knotweed to take root and compromise your property or site.

The most defining characteristics of Japanese knotweed identification are its spade-shaped (as in the playing card shape)leaves and bamboo-like stems.
