Japanese Knotweed - Early Stages - 13th April 2018 The above picture portrays the early stages of the Japanese Knotweed, and over the next few weeks we will be monitoring the growth and updating its progress via this page! The little weed might look innocent, but behind its false exterior lies a plant that can leave building foundations and drains in danger of uprooting. And if left to spread, it could leave homeowners facing a hefty fine or even a prison sentence.
Japanese Knotweed is capable of growing eight inches in one day, it deprives other plants of their key nutrients and water. The plant's roots can extend up to 3m in depth and 7m in all directions and in some cases, can grow at a rate of more than a yard a week.
Japanese Knotweed - Mid-Early Stages - 25th March 2018
The growth since our previous update, is highly noticeable. In just 12 days, it has grown substantially! This comparison alone really demonstrates the growth rate of Japanese Knotweed.
Japanese Knotweed is a fast-growing and strong clump-forming perennial, with tall, dense annual stems. Stem growth is renewed each year from the stout, deeply-penetrating rhizomes (creeping underground stems).
If you notice Japanese Knotweed on your property, ensure you seek the correct advice as quickly as possible. It is an invasive plant, and given the chance, will cause serious trouble to any property.
The Plant (scientific name Fallopia Japonica) was brought to Britain by the Victorians as an ornamental garden plant and to line railway tracks to stabilise the soil.
Japanese Knotweed - 2nd May 2018 - Back to the Early Stages! Unfortunately the JKW has been given a slight hair cut - So it's back to the early growth stages. Not all is in vain though, as the next few weeks will prove that a simple trim, is just not enough to repel the undeniable persistence, that is Japanese Knotweed.
It may be invasive. But some say it's also delicious... There are several interesting recipes to make using the plant's peculiarly sweet rhizomes. Why not try knotweed crumble “ it's apparently delicious! (We dont recommend growing your own!...)
In no more than 3 days alone, the Knotweed has really shown its persistence, and growth-rate. It's almost completed a full swing and returned back to its 'pre-haircut' stage on the 25th April.
It'll shed its leaves in winter and 'play dead'... But don't be fooled... It'll be back in spring.
Japanese Knotweed - 16th May 2018 - The Second Trimming We're not having much luck with the 'beloved' Knotweed... Once again it's been given a trim. Although as you can see, a trim alone is never enough to combat the persistence & enthusiasm of the Knotweed.
"Success for the JKW is stumbling from failure, to failure, with no loss in enthusiasm."
The plant is immune to burning. Phoenix-like, it rises from the ashes.
Japanese Knotweed - 31st May 2018 - Growth Update It's been 15 days since our last update, and as expected the Knotweed is once again growing at an expeditive rate.
Leave just one tiny piece of rhizome behind and it'll grow into a new plant, which will then spread like mad. We're not exactly keen on it, but you have to admire its sheer tenacity. As it rarely seeds, it is mostly spread by people, machinery and water transporting fragments to new sites.
Japanese Knotweed - 6th June 2018 - Growth Update 2 It has been 21 days in total without any known interruption to the growth of the JKW - Which is a surprise, considering it's classed as one of the UK's most hated, feared and potent invasive species!
In its homeland “ Japan, China and Taiwan “ Knotweed doesn't cause anywhere near as much harm and damage as it does out of its natural context. This is because it has plenty of natural predators like fungal pathogens and insects. Sadly it doesn't have any within the UK
Japanese Knotweed - 15th June 2018 - Growth Update 3 The Knotweed is now starting to grow more so outwards, than upwards. Still keeping consistent with it's tremendous growth rate (in some cases, 10cm a day) JKW can also reach heights of up to 3 metres long with a root spread of 7m or more!
JKW will grow absolutely anywhere, as happy on very poor soil as it is in good soil. It is so dense and strong it obliterates anything that tries to grow beneath it, and is strong enough to damage asphalt and even concrete. Which means it can significantly reduce the value of land and property.
And in the mean time, check out the damage below that Japanese Knotweed is capable of.
