How to Remove Japanese Knotweed
There are various options for Japanese knotweed removal, all of which come with our Insurance Backed Guarantee.
Knotweed Excavation is the best way to achieve complete Japanese knotweed removal and is the only way to ensure total knotweed removal. This solution involves removing all Japanese knotweed growth, the root system and all contaminated soil. Our experts ensure the thorough and complete knotweed removal. Leaving as little as 0.7g of rhizome can result in the recurrence of knotweed growth.
Root barrier is then used to prevent the spread or to lock in ground containing knotweed plant material.
Knotweed Chemical Treatment
Chemical Treatment (herbicide) will not remove Japanese knotweed, but will help control its growth. Japanese knotweed treatment will exhaust the plant from producing aerial growth and prevent its natural spread. If the knotweed area is likely to be disturbed physical removal of the knotweed may be required instead.
Treatment methods include stem injection, herbicide spray and leaf wiping. Our herbicide programmes are packaged within a 10-year Knotweed Management Plan (KMP), which comes with an Insurance Backed Guarantee.
Japanese Knotweed Removal Cost
The average cost to remove Japanese knotweed 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.
