Why Japanese knotweed is a problem

Why is Japanese knotweed a problem? In essence, Japanese knotweed has no natural enemies in Scotland and the UK. In its native Asia the plant is controlled by fungus and insects. Due to the lack of natural control and the speed of growth, Japanese knotweed competes and generally forces out other native plant species that cannot compete with the tall summer growth or the thick mulch of decaying canes and leaves in the winter - a perfect environment for rats and rodents.

Why Japanese knotweed is a problem to property

As Japanese knotweed can grow up to 10cm per day and because of this rapacious growth it has been known to cause damage to building structures and substructures. Typical damage includes:

• Damage to tarmac and paving areas
• Damage to building foundations
• Damage to retaining wall structures
• Reduction in property values

The knotweed exploits weakness in building structures as a result of its rapid growth. With the ability to grow through walls, tarmac and concrete it is no wonder that property owners should be concerned if they find Japanese knotweed on their property.
