The question: Is the legendary concrete-smashing, tarmac-raising Japanese knotweed really the thug it is often made out to be, for the unsuspecting, gardening home-owner? It is certainly not something you want sitting on your doorstep.
How Fast Does It Grow
You occasionally read horror stories where innocents buy properties where the previous owners have deliberately sought to deceive, by mowing out every trace of the weed before moving on, and there are all sorts of scary things said about property values where knotweed is known to be lurking.
But generally knotweed is not something that creeps into your property behind your back. Most gardeners know very well what they are dealing with, and it would seem that this plant, introduced innocently into this country from Japan as an ornamental plant almost two centuries ago, is always an invader from wild, untended ground beyond garden owners’ control.
As such, it is extremely difficult, if not impossible, to get the upper hand without the determined use of strong chemicals.
Digging out even what seems like a small infestation is generally not a successful option: major roots from which re-growth inevitably appears can be as much as 7ft below ground. As with other far less serious but much-dreaded perennial weeds, such as bind weed and ground elder, every scrap of stem that remains in the soil is capable of becoming a new, invasive plant.

On no account should any cut stems or roots be put into green waste bins or domestic compost bins without being dried-off thoroughly in the sun (and thus killed) for days or even weeks beforehand. The 1981 Wildlife and Countryside Act made it illegal to plant Japanese knotweed in the wild or to allow it to grow by carelessly disposing of unwanted cuttings or soil.
What can gardeners do about Japanese Knotweed?
The eradication of Japanese knotweed is a slow process. Here are some tips from the RHS. Visit the RHS website for more.
Digging out is possible, but given how deep the rhizomes can penetrate, the plant usually grows back. Disposal is also a problem as Japanese knotweed is classed as “controlled waste” under the Environmental Protection Act 1990, which means you have to dump it at a licensed landfill site.
To destroy any Japanese knotweed remains on site, allow the cut canes to dry out, then burn them. On no account add them to your normal household waste.
You could try one of the glyphosate-based weedkillers available from garden centres. Glyphosate is usually applied to the foliage and then passes within the plant to the underground parts. It usually takes at least three to four seasons to eradicate Japanese knotweed, but professional contractors have access to more powerful weedkillers and may reduce this period by half.
Glyphosate-treated knotweed will often produce small-leaved, bushy regrowth 50-90cm (20in-3ft) high the following spring. This looks very different to the normal plant but it is essential to treat this regrowth. Give us a call at Japanese Knotweed Removal Stoke on Trent
