Japanese knotweed is one of the first colonizers of volcanoes, it can break up through the hardened magma and grow successfully in these rocky soils. So a little heat from a flame thrower will have no effect at all and may even encourage more rampant growth.

The best way to go about killing off Japanese knotweed in Alfreton is through the use of herbicides, we use two different ones. One is not available to the public in any form and you have to have specific licences and qualifications to spray it. The other is 300x stronger than the version that is available to the general public.

Both herbicides are what they call translocating herbicides this means they are absorbed by the leaves and stems through the stomata and then travel throughout the plant inhibiting the natural internal process within the plant and thus killing the Japanese off from the root to the growing tip.
