Stem Injection is our preferred method to eradicate invasive weeds including Japanese Knotweed, Himalayan Balsam and Giant Hogweed. The process involves the application of a professional grade herbicide concentrate into the stem of the plant. The stem injection process enables the herbicide to be absorbed far quicker than if sprayed "foliar application" and poses no risk to surrounding vegetation. The stem injection process can be time consuming, however the cost is a fraction of the cost of some other methods of Japanese Knotweed Eradication. All treatments are undertaken in accordance with the COSHH, Control of pesticides regulations and the environmental Protection act 1990. Staff are fully qualified & hold relevent qualifications pa1, pa6, pa6w.
Japanese Knotweed was introduced to the UK in 1800's as an ornamental plant. The invasive nature of the plant was observed by early 1900's and its planting was no longer advised. Japanese Knotweed is now regarded as one of the most difficult invasive plants to deal with. The plant grows rapidly with new shoots appearing in the spring, by early summer they plant grows to around 3m in height. All Japanese Knotweed plants in the UK are female, meaning the plant is only spread by physical means such as moving contaminated soil, fly tipping and riverbank erosion. Selling a property with Japanese knotweed in close proximity can prove very difficult. Many mortgage providers refuse to lend on properties with a Japanese Knotweed problem due to its potential for causing structural damage and difficulty to eradicate.
Himalayan Balsam was introduced to the UK around the same time as Giant Hogweed and Japanese Knotweed. Within ten years, however, Himalayan Balsam had escaped from the confines of cultivation and begun to spread along river systems. Destroying Himalayan Balsam by physical means often makes the problem worse by aiding seed dispersal.
Giant Hogweed is a close relative to cow parsley is another common invasive which often reaches 10 feet in height. Chemicals in the sap cause photosensitivity which means skin becomes very sensitive to sunlight leading to blistering, pigmentation and long-lasting scars.
