Japanese knotweed in london

The best time to spay Japanese knotweed is when the plant is actively growing. This is because, at this stage, the plant is most vulnerable to herbicide treatment. The herbicide we use is a systemic translocating herbicide, which means that once it is absorbed, it moves through the plant, affecting it from within. Notably, the herbicide is most efficient on warm days. Warm temperatures help the plant to actively absorb the herbicide, increasing its effectiveness.

In our approach, we employ various chemicals to treat Japanese knotweed. Among these, one is significantly stronger than what is typically available to the general public, making it more potent and effective in combating the plant. Additionally, there is another herbicide that is not available to the public in any form, further ensuring that our treatment remains exclusive and highly targeted for optimal results. By using these specialised chemicals during the plant’s active growth phase and under the right weather conditions, we maximise the chances of effectively eliminating the knotweed.
