Why Professional Help is Essential for Japanese Knotweed Stem Injection Treatment
Japanese Knotweed is an extremely resilient weed, and can spread rapidly if managed incorrectly. As stated above, it is also able to grow back from the smallest of roots, and for these reasons, eradicating it permanently requires the attention of experts. Professional application of the stem injections is important, as it addresses both the visible weeds and treats the deep roots to try and halt re-growth.
At Japanese Knotweed Specialists, we have the experience, knowledge, and tools to be able to correctly apply stem injection treatments that without damaging the surrounding plants and environment. Knotweed, if left untreated, can have legal implications and even cause damage to property, which is why we always recommend choosing a professional service to take care of the problem, so as to guarantee results, protect your property in the future, and to ensure you avoid any legal issues that could arise from an outbreak.

Japanese Knotweed Stem Injection Treatment, Explained
Japanese Knotweed stem injection is an alternative to foliage spraying, which can affect and kill other nearby plants. By injecting a concentrated dose of Glyphosate Herbicide into each individual cane using equipment specifically designed for the treatment and eradication of Japanese Knotweed, only the invasive weed is targeted, leaving surround plants safe. Often this method is chosen on residential projects due to the precise nature of the application.
This method of direct Japanese Knotweed stem injection of herbicide is highly effective as it is absorbed throughout the rhizome and deep into the plant’s root system, helping to completely eradicate the troublesome plant.
Japanese Knotweed stem injection is far less risky to both the environment, waterways, and neighbouring plants. In environmentally sensitive areas, for example, where the Japanese Knotweed is on or near water, we will treat that too. Using the stem injection treatment method will minimise any risk to water and the environment. Our highly experienced team always carefully assess each project and Japanese Knotweed control method to ensure any risks are kept to a minimum.
Stem injection treatment offers a cost-effective approach to managing Japanese knotweed. However, if you’re planning further landscaping or development, additional steps such as excavation may be necessary. This approach applies to both residential and commercial projects, and our experts are fully equipped to handle these requirements.












Benefits of Japanese Knotweed Stem Injection Treatment
Stem injection treatments are a highly effective option for eradicating Japanese Knotweed, with a number of advantages over some of the other methods available, such as:
- Broad Applicability: Stem injections are suitable for a range of conditions, from residential gardens to commercial properties.
- Proven Superiority: Stem injections and herbicide treatments have been proven to be more effective at treating knotweed than manual removal.
- Long-Term Effectiveness: Japanese knotweed stem injection treatment can weaken the plant more rapidly, reducing the chance of regrowth and potentially eliminating the need for repeat applications.
- Reduced Environmental Impact: Since the treatment is injected directly, there’s minimal drift or contamination, making it safer for nearby plants, animals, and water sources.
Stem injection treatment is an effective option, especially when you need to control Japanese knotweed with minimal disruption to the environment and guarantee a long-term solution to the issue.
