Japanese knotweed on a development site

Japanese knotweed can make a site economically unviable to develop. 

Recently we were commissioned to assess a residential development site that had been undergoing a knotweed herbicide treatment programme by another Japanese knotweed specialist for 7 years, to check whether the knotweed was eradicated prior to site purchase. Our client was looking to build fourteen houses on the site.

Environet's Reflection on 2016

Another year has passed, making it over 20 years that we've now been in business.  

We've continued to grow, not only on the knotweed front. I'm pleased to say two of our employees have given birth this year, so we now have two beautiful babies being trained up on how best to tackle knotweed. There must be something in the air, as a further two employees are expecting babies in 2017, congratulations to all of them.

“Helloweed” - trick or treat time for Japanese knotweed

Trick or treat - don't be fooled, Japanese knotweed is still alive.

It's Halloween again that time of year in the knotweed calendar marking the conclusion of what many people think is the end of the knotweed treatment season. It’s true enough that the knotweed is preparing for its winter dormancy period, where the leaves go yellow and fall, leaving brittle hollow canes, tricking people into thinking the knotweed has at long last died. Of course it’s just disguised as dead, with healthy underground orange rhizomes the colour of pumpkins.

Japanese knotweed and construction sites – herbicide treatment or physical removal?

It’s a question we’re often asked, and there is a very clear answer. 

If your planned works are likely to result in ground disturbance do NOT rely on herbicide alone. The entire rhizome system should be removed, because the chances are that not all of the rhizome system will be killed by herbicide, the consequence being that your groundworks will spread the knotweed around the site, and possibly off-site too.
