How to stop Japanese knotweed spreading in Sheffield

Japanese knotweed is becoming an increasingly common problem for homeowners, landowners and businesses across Sheffield, and without gaining control it will rapidly spread. We get knotweed under control or remove knotweed for good.


Excavation is the only option if you need to completely remove Japanese knotweed and eliminate risk of it spreading. We’ve been excavating knotweed in Sheffield and the north since 2010. Our services are fully compliant with industry standards and come with an insurance backed guarantee.

Japanese knotweed is a highly resilient invasive species of weed that is capable of growing new shoots from its root network. These special roots are known as rhizomes, and even a tiny piece as small as 0.5g is capable of allowing the infestation to regrow. With root systems that bury deep into the ground, excavation of the contaminated soil is the best way to completely remove the infestation.

A herbicide TREATMENT plan will control knotweed 

Chemical Treatment (herbicide) is a popular option in Sheffield and many cities – especially for residential properties. Herbicides control its growth, and therefore stop the spread. Japanese knotweed treatment will exhaust the plant’s ability to grow and will force it into a dormant state .

Over the course of the plan, the treatment programme will prevent the plant producing aerial growth and additionally, prevent the rhizomes from growing further. If the knotweed area is likely to be disturbed physical removal of the knotweed may be required instead.

The herbicide is typically applied via spraying, however in areas where other plants need to be protected from the herbicide we will use stem injection or leaf wiping. Our herbicide programmes are packaged within a  Knotweed Management Plan (KMP), which comes with an Insurance Backed Guarantee.

The average cost to remove Japanese knotweed in Sheffield varies, depending on the methods involved and the size of the affected areas. If it is identified and dealt with promptly, the costs of removing Japanese knotweed can be kept to a minimum. Long-term herbicide treatment is usually the most cost-effective control method. Our professionally delivered herbicide treatment programme will provide successful chemical control of Japanese knotweed within a period of 3-7 years.

Excavation of Japanese knotweed costs more than herbicide treatment due to labour, materials, waste removal and reinstatement costs. However, it ensures complete Japanese knotweed removal allowing free use or development of the property. We provide cost-efficient excavation due to our extensive experience whilst minimising waste volumes.

Following our professional surveys we will provide you with a no-nonsense, comprehensive report with no-obligation recommendations and quotes.
