Invasive Weed Control


Some non-native plant species can become a problem because they are bigger, faster-growing or more aggressive than native species.

Three of the most invasive non-native plants we are asked to treat are:

Japanese knotweed – Japanese knotweed appears to have no natural enemies in Britain. It’s hard to control, as tiny fragments of its root can produce a living plant. It can grow as much as two centimetres per day, will grow in any type of soil, no matter how poor, and can grow through walls and concrete.

Giant hogweed – Giant hogweed can grow up to five metres tall and grows mainly in areas of damp soils, like river banks. Giant hogweed can have adverse effects on skin following contact. Symptoms are usually noticeable within 24 hours, including blisters and swelling on the skin, which may be made worse by exposure to the sun. If you feel unwell after contact with giant hogweed, speak to your doctor.

Himalayan balsam – Himalayan balsam grows fast and can reach two to three metres in height. It rapidly spreads on the banks of slow-moving watercourses and becomes dominant, stopping other plants growing.


We have a range of tried and trusted cost-effective environmentally aware invasive weed solutions, to fit client’s timescales, budgets, and site specific requirements, as well as meeting all regulations

Our experienced and fully qualified in-house operatives will carry out site visits throughout the treatment period with continued monitoring to ensure eradication.

Legal Responsibility

It is an offence under section 14(2) of the Wildlife and Countryside act 1981 to “plant or otherwise cause to grow in the wild” any plant listed in Schedule nine, Part II to the Act. This includes Japanese knotweed. It is not an offence to simply have it growing in your garden or on your land and there is no specific legal requirement to control it if it is (unless doing so forms part of a legally binding contract or agreement with another party).
