Knotweed removal methods are not as simple as cutting back the foliage – the vast network of root systems below ground will also require treatment.
Treatment depends on how vast the knotweed is, what damage the root system has done below soil and the location of the weed.
Using our experience and honest approach, we can work with you to undertake the most effective and practical course of treatment at a fixed fee, with no hidden extra charges and the amount of the survey deducted from treatment costs. Our management plans will cover the length of your treatment and may also include periodic surveys to safeguard that your property stays weed free.
Some of ways of removing Japanese knotweed and treatments we use effectively are:
Herbicide foliage sprays
A foliage and root system herbicide spray is a cost effective option for the removal of Japanese Knotweed. Generally used on residential sites or sites that are not subject to strict Japanese knotweed deadlines. Once the herbicide spray is absorbed down to the rhizomes for the full length of the treatment plan then no regrowth will form.
Dependent on many factors, using herbicide treatment can take between 3-5 Growing Seasons. This is the most cost-effective treatment available.
Your guarantee will be issued from day 1 of proceeding with the treatment plan. Subject to our T’s & C’s.
Stem injection is a method of applying a concentrated dose of herbicide directly in to the stem of the plant, via a needle directly in to the stem, trans-locating the herbicide through the roots and rhizomes.
Stem Injection is less risky to the environment, as it reduces the risk of spray drift, which could cause harm to other plants and nearby water.
Stem injection can be completed in all weather and further treatment may be required until no further regrowth is observed.
Knotweed barriers are used to prevent the spreading of the weed. If laid correctly by a licenced contractor like The Knotweed Experts, the membrane is laid underground and contains the rhizomes. Knotweed membranes are particularly effective to help stop the spread of the roots on to neighbouring land or to stop the Knotweed coming back onto your property, they are usually used alongside other removal treatments.
Soil sifting and screening
The Knotweed Experts will sift through all of the soil and remove the Knotweed rhizomes, leaving knotweed free soil on site. Soil sifting is a popular course of treatment, as there is reduced waste to move from site and is an extremely effective treatment.
Generally used for larger land projects but can be used on residential sites, excavation is a quick and effective process for knotweed removal. Infested waste can be disposed of on site where able to, or the waste can be removed and located to a licenced landfill site.
