SHORT ANSWER: Japanese knotweed can grow up to 10cm per day during the summer months.
Japanese knotweed has a reputation for fast, aggressive growth. Not only can this invasive plant species grow through cracks in brickwork and concrete, it can do so with rather frightening speed!
Japanese knotweed's growth rate depends on the time of year. As we've discussed previously (see When Does Japanese Knotweed Grow?) the plant goes dormant during the winter months, then re-emerges in the spring.
Summer is when the plant hits its top growing speed. Japanese knotweed loves warm weather, and it has been known to grow by as much as 10cm per day during the summer months!
How to stop Japanese knotweed in its tracks
If you've got Japanese knotweed on your property, it's important to tackle it ASAP before it becomes a big problem. Since this plant grows so quickly, the wisest thing to do is take action right away!
That said, we don't recommend jumping in and attempting to remove Japanese knotweed yourself. Our blog on DIY Japanese Knotweed Removal goes into more detail, but suffice it to say that Japanese knotweed is subject to some pretty strict rules here in the UK and you can get in big trouble if, while attempting to get rid of it, you accidentally help this invasive species to spread into the wild.
Far safer, then, to call an expert. Get in touch with a specialist Japanese knotweed company like Taylor Total Weed Control - we can carry out a Japanese knotweed survey, assess the extent of your infestation, and recommend the best course of action.
