Japanese knotweed 2018 so what now?

Friday 5th January 2018

Another year another season of Japanese knotweed and Im looking forward to it. I take great pride in signing contracts off, when the knotweed has been eradicated, monitored for re-growth and after two seasons with no growth, we can issue a Certificate of Eradication. That is the best part of my job!

The good news for us and our customers is that we can continue using glyphosate based herbicides. Without this vital resource, we would have no tools available to use in environmentally sensitive areas such as watercourses, etc. The other possible options in these areas (non-chemical) would involve the mass removal or burial of the affected soils which is hugely costly and uses huge amounts of fossil fuels.

I expect to see more invasive weeds in 2018. In recent years, we have seen more plants causing problems, and known weeds getting worse. The main terrestrial plans that are not (currently) included in Schedule 9 of The Wildlife and Countryside Act (1981) would for me include Himalayan knotweed (which hybridises readily with Japanese knotweed and is now spreading rapidly in many parts of the country) and also many species of bamboo.

Bamboo is an important weed in its own right and we see large infestations of this plant, which can cause very real issues with neighbours! Bamboo may also (like knotweed) lift paving slabs, destroy hard surfaces and infest surrounding ornamental areas, killing the other plants by outcompeting them. Its a real thug and takes a number of years to kill.
