Japanese knotweed typically grows to a max height of 2 metres, but in some extreme cases, it can grow even taller!
Japanese knotweed – or fallopia japonica – is an invasive species found in the UK and across most continents. If the name sounds familiar to you, that’s probably because it’s one of the most well-known (and hated) invasive species in the UK.
Knotweed is well-known for its very deep and extensive rhizome system, the very feature that makes it so difficult to permanently remove. While knotweed is known for its downward growth, if you’ve found your way to this blog, you’re likely wondering just how tall Japanese knotweed can grow.
How tall can knotweed grow?
Japanese knotweed typically grows to a maximum height of about 2 metres, but in some extreme cases, it has been known to reach heights of up to 3 metres! Anything taller that that is likely to be Giant Knotweed, a strain that is well known for being similar to knotweed, just much bigger!
Japanese knotweed reaches its tallest heights in the summer months, its peak growing season. If you’d like to learn more about identifying Japanese knotweed throughout the different seasons, check out our informational page on Identifying Japanese Knotweed.
